ABSTRACT
SUMMARY: The application effect of transversus abdominis plane block (TAPB) combined with thoracic paravertebral block (TPVB) or erector spinae plane block (ESP) under ultrasound guidance in endoscopic radical resection of esophageal cancer under general anesthesia was studied. From March 2021 to February 2022, patients who underwent endoscopic radical resection of esophageal cancer in our hospital were selected as the research object, and 90 patients were selected as the samples. Patients were divided into groupA and group B according to the difference of blocking schemes. Group A received ESP and Group B received TPVB. The dosage of sufentanil, nerve block time, awakening time and extubation time of the two groups were counted. The postoperative pain, sedation effect, sleep satisfaction and analgesia satisfaction of the two groups were compared, and the complications of the two groups were observed. The nerve block time and extubation time in group A were shorter than those in group B (P0.05). At T2, T3 and T4, the visual analogue scale (VAS) scores of group A at rest and cough were significantly lower than those of group B (P0.05). The satisfaction of sleep and analgesia in group A was higher than that in group B (P0.05). The analgesic effect of ultrasound-guided TAPB combined with ESP is better than that of ultrasound-guided TAPB combined with TPVB, and it can shorten the time of nerve block and extubation, which is worth popularizing.
Se estudió el efecto de la aplicación del bloqueo del plano transverso del abdomen (TAPB) combinado con el bloqueo paravertebral torácico (TPVB) o el bloqueo del plano del erector de la columna (ESP) bajo guía ecográfica en la resección radical endoscópica del cáncer de esófago bajo anestesia general. Desde marzo de 2021 hasta febrero de 2022, en nuestro hospital, se seleccionaron como objeto de investigación pacientes sometidos a resección radical endoscópica de cáncer de esófago, y como muestra se seleccionaron 90 pacientes. Los pacientes se dividieron en el grupo A y el grupo B según la diferencia de esquemas de bloqueo. El grupo A recibió ESP y el grupo B recibió TPVB. Se contaron la dosis de sufentanilo, el tiempo de bloqueo nervioso, el tiempo de despertar y el tiempo de extubación de los dos grupos. Se compararon el dolor posoperatorio, el efecto de la sedación, la satisfacción del sueño y la satisfacción de la analgesia de los dos grupos y se observaron las complicaciones de los dos grupos. El tiempo de bloqueo nervioso y el tiempo de extubación en el grupo A fueron más cortos que los del grupo B (P0,05). En T2, T3 y T4, las puntuaciones de la escala visual analógica (EVA) del grupo A en repo- so y tos fueron significativamente más bajas que las del grupo B (P 0,05). La satisfacción del sueño y la analgesia en el grupo A fue mayor que en el grupo B (P0,05). El efecto analgésico de la TAPB guiada por ecografía combinada con ESP es mejor que el de la TAPB guiada por ecografía combinada con TPVB, y puede acortar el tiempo de bloqueo nervioso y extubación, lo que vale la pena popularizar.

Abstract Background: The present study explored the role of continuous erector spinae plane (ESP) block for analgesia as well as its impact on pulmonary functions in patients with multiple rib fractures. Methods: Ten patients with multiple rib fractures were enrolled after getting informed and written consent. Ultrasound-guided ESP block was performed at the level midway between the fractured ribs followed by the insertion of the catheter. Pre- and post-block VAS score, hemodynamics, respiratory rate (RR), peripheral oxygen saturation (SpO2), inspiratory capacity (IC), blood gases (PaO2 and PCO2), and complications were compared. Results: Pain scores at rest as well as on movement showed a significant reduction from 5.9 and 7.5 pre block to 1.6 and 2.5 respectively at 96 hours (p < 0.0001). Similarly, RR, SpO2, IC, and PaO2 were significantly better after the block placement (p < 0.001). Conclusion: Continuous ESP block provide adequate analgesia with better respiratory functions in patients with multiple rib fractures.
ABSTRACT
Objective To investigate the correlation between CT parameters of erector spinae muscle(ESM)and pulmonary function in elderly patients with chronic obstructive pulmonary disease(COPD),and to analyze its predictive value for the prognosis of patients.Methods A total of 120 COPD patients were included as the case group(including 60 cases in stable stage and 60 cases in acute exacerbation stage),and 60 smokers were selected as the control group.The differences of ESM CT parameters and pulmonary function parameters in each group were compared.According to the prognosis of COPD,patients were divided into good prognosis group(n=106)and poor prognosis group(n=14),and the predictive efficacy of ESM CT parameters on the prognosis of COPD patients was analyzed.Results The pulmonary function parameters,ESM cross sectional area(CSA)(ESMCSA)and ESM local volume in the case group were significantly lower than those in the control group(P<0.05).ESMCSA and ESM local volume were positively correlated with inspiratory capacity(IC),vital capacity(VC),forced vital capacity(FVC)and forced expiratory volume in one second(FEV1)(P<0.001).The average muscle density of ESM was positively correlated with IC,VC and FVC(P<0.05),but not with FEV1.The area under the curve(AUC)of ESMCSA and ESM local volume in predicting poor prognosis of COPD patients was 0.769[95%confidence interval(CI)0.661-0.876]and 0.827(95%CI 0.734-0.919),respectively.Conclusion There is a certain correlation between the CT parameters of ESM and the pulmonary function parameters of COPD patients,among which the ESMCSA and the ESM local volume have high predictive efficacy for the prognosis of COPD patients.
ABSTRACT
@#Phantom limb pain (PLP) is difficult to control, and patients frequently exhibit inadequate relief from medications or encounter unbearable side effects. We present here a novel application of erector spinae plane (ESP) block to manage PLP. Our patient is a 23-year-old, college student, diagnosed with high-grade osteosarcoma of the right humerus who underwent a right shoulder disarticulation. He reported PLP despite multimodal analgesia postoperatively. An ESP block using a high-frequency linear probe ultrasound was performed. A G23 spinal needle was advanced inplane toward the right T3 transverse process. After negative aspiration, 20 mL of therapeutic solution containing bupivacaine 0.25%, lidocaine 1%, epinephrine 5 mcg/ml, and 40 mg methylprednisolone was injected. After the procedure, the patient reported that his PLP went down to NRS 1/10. He consistently reported to have an NRS score of 0-1/10 on succeeding consultations despite discontinuation of opioid and pregabalin. In literature, ESP block has been used as a regional technique for shoulder disarticulation surgery and other neuropathic pain conditions, but no account has shown its use for PLP treatment. The procedure was successfully done to alleviate the upper extremity phantom limb pain, significantly reduce analgesic requirements, and improve tolerance of physical therapy and overall quality of life.

Objective To explore the efficacy of ropivacaine combined with dexmedetomidine for ultrasound-guided erector spinae plane block(ESPB)in elderly patients undergoing thoracoscopic radical surgery for lung cancer.Methods A total of 119 lung cancer patients who underwent thoracoscopic radical resection of pulmonary carcinoma at the First Affiliated Hospital of Henan Polytechnic University from October 2020 to October 2022 were selected and randomly divided into the observation group(n=59)and the control group(n=60),with 3 patients excluded from the observation group and 4 patients excluded from the control group.Finally,56 patients were included in each group.Patients in the control group received ultrasound-guided ESPB with ropivacaine,while patients in the observation group received ultrasound-guided ESPB with both ropivacaine and dexmedetomidine.The pre-anesthesia preparation,anesthesia induction,and anesthesia maintenance were the same for patients in both groups,and patients in both groups used patient-controlled intravenous analgesia to relieve pain after surgery.The heart rate(HR)and mean arterial pressure(MAP)of patients in the two groups after entry(T1),successful block(T2),skin incision(T3),and end of surgery(T4),as well as the visual analogue scale(VAS)scores at rest and activity 6,12,24,and 48 hours after surgery were recorded.The amount of analgesic medication used,the number of analgesia pump presses,and the incidence of delirium and adverse reactions were compared between the two groups 48 hours after surgery.Results The MAP and HR of patients in the two groups at T2 and T3 were significantly higher than those at T1 and T4(P＜0.05).However,there was no significant difference in MAP and HR between the two groups at T4 and T1(P＞0.05),and there was also no significant difference in MAP and HR between the two groups at T2 and T3(P＞0.05).The patients in both groups showed no significant difference in MAP and HR at T1(P＞0.05),while at T2,T3,and T4,the MAP and HR in the observation group were significantly lower than those in the control group(P＜0.05).The patients in both groups had lower VAS scores at rest and activity 12,24,and 48 hours postope-ratively compared to 6 hours postoperatively(P＜0.05).The patients in both groups had lower VAS scores at rest and activity 24 and 48 hours postoperatively compared to 12 hours postoperatively(P＜0.05).The patients in both groups had lower VAS scores in both resting and active states 48 hours after surgery compared to 24 hours after surgery(P＜0.05).There was no significant difference in VAS scores at both rest and activity 6 hours after surgery between the two groups(P＞0.05).At 12,24,and 48 hours after surgery,the patients in the observation group had lower VAS scores in both resting and active states compared to the control group(P＜0.05).Compared with the control group,the observation group used fewer analgesic drugs and pressed analgesia pumps less 48 hours after surgery(P＜0.05).The incidence of overall adverse reactions within 48 hours after surgery was 5.36％(3/56)and 8.93％(5/56),respectively;there was no significant difference in the incidence of overall adverse reactions between the two groups(x2=0.135,P＞0.05).The incidence of delirium within 48 hours after surgery in the control and observation groups was 14.29％(8/56)and 3.57％(2/56),respectively.The incidence of delirium in the observation group was significantly lower than that in the control group(x2=3.953,P＜0.05).Conclusion The use of ropivacaine combined with dexmedetomidine for ultrasound-guided ESPB in elderly patients undergoing thoracoscopic radical surgery for lung cancer can maintain perioperative hemodynamic sta-bility,improve analgesic effect,and reduce the dosage of analgesic drugs,the number of analgesia pump presses,and the inci-dence of postoperative delirium.
ABSTRACT
Objective:To compare the effects of transverse abdominis plane block and incision infiltration anesthesia on the early postoperative recovery in the patients undergoing thoracoscopic lung resection with general anesthesia.Methods:Eighty American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients, regardless of gender, aged 50-78 yr, with body mass index of 18-30 kg/m 2, scheduled for elective thoracoscopic lung resection under general anesthesia, were divided into 2 groups ( n=40 each) using a random number table method: incision local infiltration group (group D) and transverse abdominis plane block group (group E). In group E, the patients were changed to the lateral position after completion of anesthesia induction, ultrasound-guided transverse abdominis plane block was performed on the affected side, with 0.25% ropivacaine hydrochloride 30 ml injected. In group D, infiltration anesthesia with 0.25% ropivacaine hydrochloride was performed before incision. Postoperative patient-controlled intravenous analgesia was carried out, and flurbiprofen axetil was intravenously injected for rescue analgesia when the numerical rating scale score at rest >3 or numerical rating scale score≥6 while coughing. Quality of Recovery-15 scale scores were assessed at 1 day before surgery and 24 and 48 h after surgery. Plasma concentrations of interleukin-6 (IL-6) and IL-1β were measured by enzyme-linked immunosorbent assay before incision, at the end of surgery, and at 24 h after surgery. The amount of remifentanil used during surgery, the number of effective pressing times of patient-controlled analgesia within 48 h after surgery, requirement for rescue analgesia, first ambulation time after surgery, time to first flatus, length of hospital stay, and occurrence of nausea and vomiting and pulmonary infection within 48 h after surgery were recorded. Results:Compared with group D, Quality of Recovery-15 scale scores were significantly increased, the amount of remifentanil used during surgery and the number of effective pressing times of patient-controlled analgesia were reduced, the rate of rescue analgesia was decreased, the time to first rescue analgesia was prolonged, and the time to first flatus was shortened in group E ( P<0.05). There were no significant differences in the plasma concentrations of IL-6 and IL-1β at various time points, time to first ambulation after surgery, length of hospital stay, and incidence of nausea and vomiting and pulmonary infection between the two groups ( P>0.05). Conclusions:Compared with incision infiltration anesthesia, transverse abdominis plane block can reduce intraoperative consumption of opioids, alleviate postoperative pain, and promote early postoperative recovery when used for thoracoscopic lung resection under general anesthesia.
ABSTRACT
Objective To investigate the effect of L4 transverse process erector spinae plane block(ESPB)before general anesthesia hip surgery in elderly patients on reducing perioperative pain and stress,thus reducing opioid consumption and improving postoperative recovery quality.Methods Sixty patients aged 65 years old and above who underwent unilateral hip surgery from January to December 2023 were randomly divided into two groups(n = 30)by using the random number table method.The ESPB group received ultrasound-guided ESPB at the L4 level with 0.3%ropivacaine(0.5 ml/kg)before induction of anesthesia,while the control group did not receive ESPB.Laryngeal mask anesthesia was administered in both groups.The induction and maintenance methods were consistent in both groups.The Numerical Rating Scale(NRS)was used to evaluate the degree of pain at 8 h and 24 h after surgery.The times of pressing analgesic pump within 24 h after surgery were recorded.The hemodynamic changes at each time point during the operation were observed.The time interval from the end of the operation to the complete recovery and to remove the laryngeal mask were recorded.Intraoperative and Postanesthesia Care Unit(PACU)opioid consumption were noted.The incidence of postoperative agitation,postoperative nausea and vomiting(PONV),dizziness,and the recovery quality score were compared.Results The NRS scores of rest pain and motion pain at 8 h and 24 h after surgery were significantly lower in the ESPB group than those in the control group,and the times of pressing the analgesic pump within 24 h after surgery in the ESPB group was significantly less than that in the control group(P<0.05).The mean arterial pressure(MAP)of the ESPB group at 20 min after peeling was lower than that of the control group[(87.2±15.5)mm Hg vs.(96.7±16.9)mm Hg,P = 0.026].The sufentanil consumption,remifentanil consumption,and the number of cases using urapidil in the ESPB group were significantly lower than those in the control group[12.5(10.0,14.0)μg vs.12.5(12.5,17.5)μg,P =0.041;270(100,400)μg vs.600(448,800)μg,P<0.001;1 case vs.11 cases,P =0.001].The Steward score at30 min after entering PACU was significantly higher in the ESPB group than in the control group[6(5,6)points vs.5(4,5)points,P<0.001].There was no statistical significance in incidence of postoperative agitation,PONV,and dizziness between the two groups(P>0.05).Conclusion Preoperative ESPB at the level of the L4 transverse process can reduce the pain score within 24 h after surgery,reduce the amount of opioid used during and after hip surgery,and improve the quality of postoperative recovery in the elderly.
ABSTRACT
Objective To compare anesthetic effects between erector spinae plane block(ESPB)and intercostal nerve block(ICNB)in thoracoscopic lung wedge resection guided by surgical pleth index(SPI).Methods A total of 46 patients who underwent thoracoscopic lung wedge resection in Wenzhou People's Hospital from July 2020 to June 2022 were selected and divided into ICNB group and ESPB group according to random number table method,with 23 cases in each group.Remifentanil infusion rate,propofol dosage and intraoperative vital signs were compared between two groups.Results The intraoperative remifentanil infusion rate in ESPB group was significantly lower than that in ICNB group(P<0.05).There was no significant difference in intraoperative propofol dosage between two groups(P>0.05).The SPI,bispectral index and mean arterial pressure in ESPB group during lung wedge resection were significantly lower than those in ICNB group(P<0.05).There was no significant difference in heart rate between two groups(P>0.05).Conclusion Under the guidance of SPI,patients undergoing thoracoscopic lung wedge resection with preoperative ESPB had low opioid consumption and stable vital signs.
ABSTRACT
Introduction: Transversus abdominis plane (TAP) block provides somatic analgesia postoperatively in cesarean sections, however erector spinae plane (ESP) block has shown to provide both somatic and visceral analgesia. Objective: To compare the efficacy of TAP and ESP blocks for pain control after cesarean section under spinal anesthesia. Methods: In a double-blind superiority trial, pregnant patients undergoing cesarean section were randomized into either bilateral TAP or ESP block groups. Primary outcome was total consumption of patient-controlled analgesia (PCA) tramadol in the first 24 hours. Secondary outcomes included time required for first rescue analgesia, post-surgery visual analog score (VAS) for pain, patient satisfaction, and adverse effects. Results: 50 pregnant patients were randomized into TAP and ESP blocks. There was no difference in the amount of PCA tramadol within the first 24 hours between both groups [100mg (63-125) in TAP group vs 75mg (38-100) ESP group]. Pain score at rest and on movement and patient satisfaction were comparable in both groups, with no difference in adverse effects. There was a slight difference in the median time for first rescue analgesia [210min (135-315) in TAP group and 270min (225-405) ESP group] (p=0.03). Conclusions: TAP and ESP blocks provide similar analgesia with comparable consumption of tramadol in the first 24 hours post-cesarean section and no difference in pain scores at rest/on movement.
Introducción: El bloqueo del plano transverso abdominal (TAP - por sus siglas en inglés), ofrece analgesia somática postoperatoria en cesárea; sin embargo, el bloqueo del plano erector de la espina (ESP - por sus siglas en inglés) ha demostrado proporcionar analgesia tanto somática, como visceral. Objetivo: Comparar la eficacia de los bloqueos TAP y ESP para el control del dolor posterior a la cesárea, bajo anestesia raquídea. Métodos: En un estudio de superioridad doble ciego, las pacientes embarazadas sometidas a cesárea se aleatorizaron bien sea al grupo de bloqueo bilateral TAP o ESP? El desenlace principal fue el consumo total de analgesia controlada por la paciente (PCA - por sus siglas en inglés) con tramadol en las primeras 24 horas. Los desenlaces secundarios incluyeron el tiempo transcurrido para la primera analgesia de rescate, el puntaje en la escala visual analógica (EVA) para dolor, la satisfacción del paciente y los efectos adversos. Resultados: 50 pacientes embarazadas se aleatorizaron entre bloqueo TAP y bloqueo ESP. No hubo diferencia en la cantidad de tramadol de la PCA dentro de las primeras 24 horas entre los dos grupos [100mg (63-125) en el grupo TAP vs 75mg (38-100) en el grupo ESP]. El puntaje de dolor en reposo y en movimiento y la satisfacción de la paciente fueron comparables en ambos grupos, sin diferencia en los efectos adversos. Hubo una ligera diferencia en la media de tiempo hasta la primera analgesia de rescate [210 min (135-315) en el grupo de TAP y 270 min (225-405) en el grupo ESP] (p=0,03). Conclusiones: Los bloqueos TAP y ESP ofrecen una analgesia similar, con un consumo comparable de tramadol en las primeras 24 horas posteriores a la cesárea y no hay diferencia en los puntajes de dolor en reposo, o en movimiento.
ABSTRACT
Abstract Introduction Laparoscopic cholecystectomy (LC) is the common surgical intervention for benign biliary diseases. Postoperative pain after LC remains as an important problem, with two components: somatic and visceral. Trocar entry incisions lead to somatic pain, while peritoneal distension with diaphragm irritation leads to visceral pain. Following its description by Forero et al., the erector spinae plane (ESP) block acquired considerable popularity among clinicians. This led to the use of ESP block for postoperative pain management for various operations. Materials and methods This study was conducted between January and June 2019. Patients aged between 18 and 65 years with an American Society of Anesthesiologists (ASA) physical status I-II, scheduled for elective laparoscopic cholecystectomy were included in the study. All the patients received bilateral or unilateral ESP block at the T8 level preoperatively according to their groups. Results There was no significant difference between the groups in terms NRS scores either at rest or while coughing at any time interval except for postoperative 6th hour (p = 0.023). Morphine consumption was similar between the groups but was significantly lower in group B at 12 and 24 hours (p = 0.044 and p = 0.022, respectively). Twelve patients in group A and three patients in group B had shoulder pain and this difference was statistically significant (p = 0.011). Discussion In conclusion, bilateral ESP block provided more effective analgesia than unilateral ESP block in patients undergoing elective LC. Bilateral ESP block reduced the amount of opioid consumption and the incidence of postoperative shoulder pain.

ObjectiveTo explore the imbalance of paravertebral muscle group for patients with unilateral lumbar disc herniation. MethodsFrom January, 2022 to January, 2023, 30 patients with unilateral lumbar disc herniation (observation group) and 30 healthy people matching in general data (control group) were measured the tension and stiffness of multifidus and erector spinae with MyotonPRO, while the observation group was assessed with Visual Analogue Scale (VAS) for pain and Japanese Orthopaedic Association (JOA) score, and the time of disease was also recorded. ResultsThe mean of bilateral tension and hardness of multifidus and erector spinae was more in the observation group than in the control group (|t| > 5.407, P < 0.001), and the tension and hardness of multifidus and erector spinae of the affected side were more than those of the unaffected side in the observation group (|t| > 11.219, P < 0.001). The tension and hardness of multifidus and erector spinae of the affected side were positively correlated with VAS score (r > 0.942, P < 0.001), and negatively correlated with JOA score (|r| > 0.886, P < 0.001). ConclusionThe tension and hardness of multifidus and erector spinae of the affected side increase after unilateral lumbar disc herniation, resulting in asymmetry.
ABSTRACT
OBJECTIVES@#With the rapid development of aging population, the number of elderly patients undergoing posterior lumbar spine surgery continues to increase. Lumbar spine surgery could cause moderate to severe postoperative pain, and the conventional opioid-based analgesia techniques have many side effects, which are barriers to the recovery after surgery of the elderly. Previous studies have demonstrated that erector spinae plane block (ESPB) could bring about favorable analgesia in spinal surgery. As far as the elderly are concerned, the analgesic and recovery effects of ESPB on posterior lumbar spine surgery are not completely clear. This study aims to observe the effects of bilateral ESPB on elderly patients undergoing posterior lumbar spine surgery, and to improve the anesthesia techniques.@*METHODS@#A total of 70 elderly patients of both sex, who were selected from May 2020 to November 2021, scheduled for elective posterior lumbar spine surgery, and in the age of 60-79 years, with American Society of Anesthesiologists class Ⅱ-Ⅲ, were divided into a ESPB group and a control (C) group using a random number table method, with 35 patients each. Before general anesthesia induction, 20 mL 0.4% ropivacaine was injected to the transverse process of L3 or L4 bilaterally in the ESPB group and only saline in the C group. The score of Numerical Rating Scale (NRS) indicating pain at rest and on movement within 48 h after operation, time of first patient control analgesia (PCA), cumulative consumptions of sufentanil within 48 hours, Leeds Sleep Evaluation Questionnaire (LSEQ) scores on the morning of day 1 and day 2 after operation, Quality of Recovery-15 (QoR-15) scores at 24 and 48 h after operation, full diet intake times, perioperative adverse reactions such as intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation were compared between the 2 groups.@*RESULTS@#A total of 70 patients were enrolled and 62 subjects completed the study, including 32 in the ESPB group and 30 in the C group. Compared with the C group, the postoperative NRS scores at rest at 2, 4, 6, and 12 h and on movementat at 2, 4, and 6 h were lower, time of first PCA was later, sufentanil consumptions were significantly decreased during 0-12 h and 12-24 h after operation, LSEQ scores on the morning of day 1 and QoR-15 scores at 24 and 48 h after operation were higher, full diet intakes achieved earlier in the ESPB group (all P<0.05). There were no significant differences in the incidences of intraoperative hypotension, postoperative dizziness, nausea, vomiting, and constipation between the 2 groups (all P>0.05).@*CONCLUSIONS@#Providing favorable analgesic effects with reduced opioids consumption, bilateral ESPB for posterior lumbar spine surgery in the elderly patients could also improve postoperative sleep quality, promote gastrointestinal functional restoration, and enhance recovery with few adverse reactions.

Abstract Introduction: Inadequate pain control after major surgery can lead to significant complications. Ultrasound (US) guided plane blocks account for significant progress in regional anesthesia. Objective: This study explored the analgesic superiority of ultrasound-guided erector spinae (ESPB) and transversus abdominis (TAPB) plane blocks in patients undergoing major ovarian cancer surgery under general anesthesia. There have been no previous studies comparing their efficacy under these circumstances. Methods: This double-blind randomized comparative study included 60 patients undergoing major ovarian cancer surgery under general anesthesia. The ESPB group (n=30), received preoperative ultrasound-guided ESPB and the TAPB group (n=30), received preoperative low TAPB. Opioid consumption, HR, MAP, visual analogue scale (VAS) and adverse events were documented over 24 hours after surgery. Results: There was a highly significant difference in tramadol consumption between the two groups, with (95% CI: 16.23 to 50.43) and (95% CI: 59.23 to 95.43) for ESPB and TAPB groups, respectively. A significant difference (P < 0.01) was shown in intraoperative fentanyl consumption with (95% CI: 113 to 135.6) and (95% CI: 141.8 to 167.6) for ESPB and TAPB groups, respectively. A highly significant longer time to first analgesic request was recorded in the ESPB group (95% CI: 5.5 -15.3) (P < 0.001). VAS had a median of 2 (1-3) and 4 (2-6) for ESPB and TAPB groups, respectively, with F(1)=18.15, P=0.001 between groups. Postoperative HR and MAP in the TAPB group were significantly higher with more incidence of PONV. Conclusions: ESPB provided a more reliable analgesia versus TAPB in patients undergoing ovarian cancer surgery.
Resumen Introducción: El control inadecuado del dolor posterior a cirugía mayor puede generar complicaciones importantes. El bloqueo de los planos guiado por ecografía representa un avance significativo en anestesia regional. Objetivo: En el presente estudio se explora la superioridad analgésica de los bloqueos guiados por ecografía del plano erector de la espina (BPEE) y del plano transverso abdominal (BPTA) en pacientes sometidas a cirugía de cáncer de ovario bajo anestesia general. No se han hecho estudios previamente que comparen su eficacia bajo tales circunstancias. Métodos: Este estudio doble ciego, aleatorizado, comparativo, incluyó a 60 pacientes sometidas a cirugía mayor por cáncer de ovario, bajo anestesia general. El grupo del BPEE (n=30), recibió un BPEE guiado por ecografía, mientras que el grupo de BPTA (n=30), recibió un BPTA preoperatorio bajo. El consumo de opioides, la FC, la PAM, la escala visual analógica (EVA) y los eventos adversos, se documentaron durante las 24 horas posteriores a la cirugía. Resultados: Hubo una diferencia estadísticamente significativa en el consumo de tramadol entre los dos grupos, con un IC del 95% de 16,23 a 50,43 y un IC del 95% de 59,23 a 95,43 para los grupos de BPEE y de BPTA respectivamente. Se demostró una diferencia estadísticamente significativa (P < 0,01) en el consumo de fentanilo con un IC del 95%: 113 a 135,6 y un IC de 95%: 141,8 a 167,6 para los grupos de BPEE y BPTA, respectivamente. El tiempo transcurrido hasta la primera solicitud de analgésico en el grupo de BPEE fue significativamente más prolongado (IC 95%: 5,5 -15,3) (P < 0,001). La escala visual analógica - EVA - tuvo una mediana de 2 (1-3) y 4 (2-6) para los grupos del BPEE y BPTA, respectivamente, con F(1)=18,15, P=0,001 entre grupos. La FC y la PAM postoperatorias en el grupo de BPTA fueron significativamente superiores, con una mayor incidencia de nausea y vómito postoperatorios. Conclusiones: El BPEE proporcionó una analgesia más confiable que BPTA, en pacientes sometidas a cirugía de cáncer de ovario.
ABSTRACT
Abstract Multimodal analgesia in cardiac surgery sternotomy includes bilateral continuous erector spinae plane block (BC-ESPB). However, the effectiveness of the local anesthetic regimens is still uncertain. The purpose of this study was to assess pain control achieved with a multimodal analgesia regimen including BC-ESPB at the level of T5 with PCA with a 0.125 % bupivacaine infusion and rescue boluses. This is a descriptive case series study which recruited 11 adult patients undergoing cardiac surgery through sternotomy in whom multimodal analgesia including BC-ESPB was used, between February and April 2021, at a fourth level institution. All patients reported pain according to the numeric rating scale (NRS) ≤ 3 both at rest and in motion, at extubation and then 4 and 12 hours after surgery. After 24 hours the pain was NRS ≤ 3 in 100 % of the patients at rest and in 63.6 % in motion. At 48 h 81 % of the patients reported pain NRS ≤ 3 at rest and in motion. At 72h all patients reported pain NRS ≤ 3 at rest and 82 % in motion. The average intraoperative use of fentanyl was 2.35 µg/kg and postoperative hydromorphone was 5.3, 4.1 and 3.3 mg at 24, 48 and 72 hours, respectively. Hence, bilateral ESP block in continuous infusion plus rescue boluses allows for proper control of acute intra and post-operative pain.
Resumen En cirugía cardiaca mediante esternotomía, la analgesia multimodal incluye el bloqueo bilateral continuo del plano erector de la espina (BBC-ESP). Sin embargo, existe incertidumbre sobre la efectividad de los esquemas de dosificación del anestésico local. Se busca evaluar el control del dolor proporcionado por un esquema de analgesia multimodal que incluye el BBC-ESP a la altura de T5 con ACP de bupivacaína 0,125 % en infusión y bolos de rescate. Se trata de un estudio descriptivo, serie de casos. Se reclutaron 11 pacientes adultos sometidos a cirugía cardiaca mediante esternotomía en quienes se usó analgesia multimodal que incluía BBC-ESP entre febrero y abril del 2021, en una institución de cuarto nivel. Todos los pacientes refirieron dolor, según la escala numérica (EN) ≤ 3 tanto en reposo como en movimiento, a la extubación, a las 4 y a las 12 horas. A las 24 horas el dolor fue EN ≤ 3 en el 100 % de los pacientes en reposo y en el 63,6 % en movimiento. A las 48 h el 81 % de los pacientes refirieron dolor EN ≤ 3 en reposo y en movimiento. A las 72 h todos los pacientes presentaron dolor EN ≤ 3 en reposo y 82 % en movimiento. El consumo intraoperatorio promedio de fentanilo fue de 2,35 ug/kg y de hidromorfona posoperatoria de 5,3, 4,1 y 3,3 mg a las 24, 48 y 72 horas. Así, el BBC-ESP en infusión continua más bolos de rescate permiten el control del dolor agudo intra y posoperatorio.
ABSTRACT
Background: Patients posted for video-assisted thoracoscopic surgeries (VATS) are nowadays managed intraoperatively by general anesthesia (GA) with the use of oral and parenteral analgesics in the post-operative period. Ongoing research points out that the erector spinae plane block (ESP Block) with local anesthetics is a safe technique for the perioperative management of pain in thoracoscopic procedures. Aims and Objectives: Our study aimed at comparing ultrasound guided ESP block using local anesthetics versus GA for perioperative pain management in patients who underwent thoracoscopic procedures. The objectives of this research were to assess the hemodynamic changes in patients undergoing the procedure, to calculate the total amount of analgesics required by patients in the next 24 h, to assess the overall patient satisfaction and complications in the post-operative period. Materials and Methods: In this prospective comparative randomized controlled trial, 40 patients aged 18–65 years planned to undergo VATS were enrolled and randomized to either group G or group E in equal numbers depending on the anesthetic technique employed. Group G patients received GA and Group E patients received ultrasound guided ESP block. Both the groups were compared for hemodynamic stability, pain in postoperative period using visual analog scale (VAS), time to first rescue analgesia requested since induction, total amount of rescue analgesia requested, overall patient satisfaction, and post-operative complications. Results: Better control of hemodynamic parameters, less post-operative pain, prolonged duration of analgesia (P < 0.05), and requirement of lesser amount of rescue analgesics were observed in patients of Group E in comparison with patients of Group G. Side effects such as post-operative nausea and vomiting were more in patients of Group G in the first 24 h (P < 0.05). Conclusion: ESP block with local anesthetics can be used as an effective sole anesthetic technique for VATS <60 min providing a longer pain free post-operative period, lesser rescue analgesic requirement, better patient satisfaction, and lesser post-operative complications.
ABSTRACT
Aims:Chest wall blocks are effective alternatives for postoperative pain control inmitral valve surgery in rightmini?thoracotomy (mini?MVS).We compared the efficacy of Serratus Anterior plane block (SAPB) and Erector Spinae plane block (ESPB) on postoperative pain relief aftermini?MVS. Settings and Design: It is a prospective, observational study. Material and Methods: A total of 85 consecutive patients undergoing continuous SAPB and continuous ESPB for mini?MVS from March 2019 to October 2020 were included. The primary outcome was the assessment of postoperative pain evaluated as absolute value of NRS at 12, 24 and 48 h. Secondary outcomes were assessment of salvage analgesia (both opioids and NSAIDs), incidence of mild adverse effects (i.e. nausea, vomiting, and incorrect catheter placement) and timing of postoperative course (ICU and hospital length of stay, duration of mechanical ventilation, ventilator?free days). Results: The median NRS was 0.00 (0.00–3.00) at 12 h and 0.00 (0.00–2.00) at 24 and 48 h. No significant differences were observed between groups. Postoperative morphine consumption in the first 24 h was similar in both groups (P = 0.76), whereas between 24 and 48 h was significantly less in the ESPB group compared with SAPB group, P = 0.013. NSAIDs median consumption and Metoclopramide consumption were significantly lower in the ESPB group compared to SAPB group (P = 0.002 and P = 0.048, respectively). Conclusions: ESPB, even more than SAPB, appears to be a feasible and effective strategy for the management of postoperative pain, allowing good quality analgesia with low consumption of opioids, NSAIDs and antiemetic drugs.
ABSTRACT
Abstract We present a 9-year-old patient with end-stage renal disease, on peritoneal dialysis, who underwent a staged prone retroperitoneoscopic bilateral nephrectomy. Bilateral nephrectomy was indicated in preparation for renal transplant in the context of genetic predisposition malignancy when immunosuppressed. The two mirror-image surgeries enable the comparison of the anesthetic management and outcomes in a single patient. Features of interest to anesthesiologists include approach to a child with chronic kidney disease, different requirements for intraoperative antihypertensives; pain management strategies, including a comparison of erector spinae plane block with and without adjunct dexmedetomidine; anesthetic management of retroperitoneoscopic pediatric surgery and the first description of using a Foley bag attached to a peritoneal dialysis catheter to aid in diagnosis and repair of posterior peritoneal cavity entry.
Resumen Se presenta un paciente de 9 años de edad con enfermedad renal terminal, en diálisis peritoneal, quien se sometió a nefrectomía bilateral retroperitoneoscópica estadificada en posición prona. Se indicó la nefrectomía bilateral en preparación para trasplante renal en el contexto de predisposición genética hacia desarrollar una patología maligna al estar inmunosuprimido. Las dos cirugías en espejo permiten hacer una comparación del manejo anestésico y de los desenlaces en un mismo paciente. Las características de interés para los anestesiólogos incluyen el abordaje de un niño con enfermedad renal crónica, con requisitos diferentes de antihipertensivos intraoperatorios; estrategias para el manejo del dolor, incluyendo una comparación de bloqueo del plano del erector espinal con y sin dexmedetomidina adyuvante; manejo anestésico de cirugía pediátrica retroperitoneoscópica y la primera descripción del uso de una bolsa Foley conectada a un catéter de diálisis peritoneal para ayudar en el diagnóstico y la reparación de la entrada de la cavidad peritoneal posterior.

Objective:Thoracic Epidural Analgesia (TEA) was compared with ultrasound?guided bilateral erector spinae plane (ESP) block in aorto?femoral arterial bypass surgery for analgesic efficacy, hemodynamic effects, and pulmonary rehabilitation. Design: Prospective randomized. Setting: Tertiary care centre. Participants: Adult patients, who were scheduled for elective aorto?femoral arterial bypass surgery. Interventions: It was a prospective pilot study enrolling 20 adult patients who were randomized to group A (ESP block = 10) and group B (TEA = 10). Monitoring of heart rate (HR) and mean arterial pressure (MAP) and pain assessment at rest and deep breathing using visual analog scale (VAS) were done till 48?h post?extubation. Rescue analgesic requirement, Incentive spirometry, oxygenation, duration of ventilation and stay in Intensive Care Unit (ICU) were reported as outcome measures. Statistical analysis was performed using unpaired Student T?test or Mann?Whitney U test. A value of P < 0.05 was considered significant. Results: HR was lower in group B than group A at 1 and 2 h post? surgery and at 0.5, 16, 20, and 32 h post?extubation (P < 0.05). MAP were lower in group B than A at 60, 90, 120, 150, 180, 210, 240, 270 minutes and at 0 hour post?surgery and at 4 hours, every 4 hours till 32 hours post?extubation (P < 0.05). Intraoperative midazolam and fentanyl consumption, ventilatory hours, VAS at rest, incentive spirometry, oxygenation, and ICU stay were comparable between the two groups. VAS during deep breathing was more in group A than B at 0.5, 4 hours and every 4 hours till 44 hours post?extubation. The time to receive the first rescue analgesia was shorter in group A than B (P < 0.05). Conclusion: Both ESP block and TEA provided comparable analgesia at rest. Further studies with larger sample size are required to evaluate whether ESP block could be an alternative to TEA in aorto?femoral arterial bypass surgery
ABSTRACT
ABSTRACT BACKGROUND: There is still a debate about what constitutes effective and safe postoperative analgesia in hepatectomy surgery. Erector spinae plane (ESP) block may be an important part of multimodal analgesia application in hepatectomy surgery. OBJECTIVES: To compare the effects of ultrasound-guided bilateral erector spinae plane block combined with intravenous (iv) patient-controlled analgesia (iv PCA), in comparison with iv PCA alone, in hepatectomy surgery. DESIGN AND SETTINGS: Randomized prospective single-blinded study in a tertiary university hospital. METHODS: Fifty patients scheduled for elective hepatectomy surgery were included in the study. Patients were randomized into the ESP group or the control group. In the ESP group, bilateral ESP block was performed preoperatively and iv PCA was used. In the control group, only iv PCA was used. Numerical rating scale (NRS) scores at rest and coughing, analgesic requirements and occurrences of nausea and vomiting were recorded. RESULTS: Intraoperative and postoperative opioid consumption, rescue analgesia requirement and resting and dynamic NRS scores were significantly lower in the ESP group (P < 0.05). There was no significant difference between two groups in terms of the presence of dynamic pain after the first postoperative hour. While all patients in the control group had nausea and vomiting, 24% of the patients in the ESP group did not have nausea and vomiting. CONCLUSION: This study showed that ESP block can be used as a part of multimodal analgesia, with the benefit of reducing opioid consumption and postoperative nausea and vomiting in hepatectomy surgery.

Objective: To simulate and evaluate the scraping and grinding work of workers with different spinal anteversion angles, and to explore the effects of different anteversion angles on the erector spinae muscles of scrapers. Methods: In November 2019, 16 male college student volunteers were recruited to simulate workers' scraping and grinding work. The parameters were 25°, 15 times/min, 15°, 30 times/min, 5°, 60 times/min respectively. The surface electromyography (sEMG) was used to collect the electromyographic signals of the erector spinae muscles, and the surface electromyographic characteristics of the erector spinae muscles were evaluated with Borg Scale. Results: There were significant differences between the maximum voluntary contraction percentage (MVE%) of the left and right erector spinae muscles groups in the three groups with different spinal anteversion angles (F(left)=13.41, P(left)<0.001; F(right)=4.74, P(right)=0.005) , and the EMG amplitude was higher at 25°, 15 times/min. At 15°, 30 times/min, MVE% of the left side was significantly higher than that of the right side (t=2.58, P=0.021) . There was significant difference in the mean power frequency (MPF) of the right erector spinae muscle in the three groups (F=9.42, P<0.001) , but there was no significant difference in the MPF of the left erector spinae muscle (F=0.30, P=0.823) . The fitting line showed that the left erector spinae muscle showed a downward trend at 5°, 60 times/min (t=-5.39, P=0.012) . Conclusion: Scrapers are less likely to be fatigued when the posture is 15°, 30 times/min, but they are more likely to be fatigued when working at 5°, 60 times/min.
