The effect of lavender aromatherapy on the level of intraoperative anxiety in caesarean case under spinal anesthesia: A randomized controlled trial.

BACKGROUND: Preoperative anxiety can be reduced by aromatherapy. This study aimed to evaluate the effect of lavender aromatherapy in reducing intraoperative anxiety in patients undergoing caesarean section (CS) under spinal anesthesia. METHODS: This study was two-armed and randomized controlled trial. A total of 96 patients who were scheduled for CS were randomly divided into two groups: the aromatherapy (A) group (n=48), comprising patients who were randomized to receive lavender aromatherapy with mask oxygen after the birth of the baby, and the control (C) group (n=48), comprising patients who inhaled carrier oil. During the preoperative period, baseline anxiety levels and Visual Analog Scale (VAS) pain scores were recorded using the State-Trait Anxiety Inventory (STAI-I) scale. After birth, two drops of oil were inhaled in an oxygen mask for 5 min. After 5 min, the Ramsey Sedation Scale was evaluated, and patients with a score of 1 received 2 mg of intravenous midazolam for sedation. The STAI-I and VAS pain scores were re-evaluated at the third postoperative hour. RESULTS: The primary outcome was the significant reduction in the need for midazolam brought about by lavender aromatherapy, and the secondary outcomes included postoperative third-hour STAI-I scores, intraoperative complications and patient satisfaction. CONCLUSION: The effectiveness of lavender aromatherapy, which reduced the need for intraoperative anxiolytics, can be offered as an alternative for pregnant women who undergo CS under spinal anesthesia.

Comparison of the postoperative analgesic effect of transversus abdominis plan block and quadratus lumborum block: A prospective randomized study.

Background and Aims: In this study, we aimed to compare the transversus abdominis plan block (TAP) and quadratus lumborum block (QL) efficacy for postoperative analgesia in patients undergoing varicocelectomy under spinal anesthesia. Methods: American Society of Anesthesiologists (ASA) 1 and 2 patients, aged 18-45 years, who underwent varicocelectomy operation under elective conditions, were included. Eighty patients were divided into three groups as TAP group, QL group, and control group by prospective randomization. The patients were operated under spinal anesthesia. At the end of the operation, TAP was applied to the TAP group with a posterior approach using ultrasound (USG) in the supine position. To the QL group, the patient was placed in the lateral decubitus position and the lateral QL was applied via USG. No block type was applied to the control group. Patient-controlled analgesia (PCA) device containing tramadol was administered intravenously at the end of the surgery in all groups. Visual analogue scale (VAS) score was questioned at 0, 2, 4, 6, 8, 10, 12, 18, 24 h in the follow-up of the patients. Intravenous 1 g paracetamol was given over VAS 4. PCA usage time and usage amounts were recorded. Results: As a result of comparing the groups according to the VAS scores at all hours were significantly different between the three groups (p < 0.001). There was a significant difference between the groups when comparing the number of PCA bolus administrations (p < 0.001). TAP and QL blocks significantly reduced the number of PCA bolus when compared with the control group (p < 0.001) but the number of PCA bolus was found to be similar between TAP and QL blocks (p > 0.05). Conclusion: TAP and QL, which are administered to evaluate the effectiveness of postoperative analgesia in patients undergoing varicocelectomy under spinal anesthesia, are both effective in reducing pain scores and the amount of analgesia consumption.

Compliance With the Surviving Sepsis Campaign Bundle: A Multicenter Study From Turkey.

Objectives Sepsis bundle compliance is not clear. We evaluated rates of compliance with sepsis bundle protocols among health care providers in Turkey. Methods Our study was carried out retrospectively. Forty-five intensive care units (ICU) participated in this study between March 2, 2018 and October 1, 2018. Results One hundred thirty-eight ICUs were contacted and 45 ICUs agreed to participate. The time taken for the diagnosis of sepsis was less than six hours in 384 (59.8%) patients, while it was more than six hours in 258 (40.2%) patients. The median [interquartile range (IQR)] times for initial antibiotic administration, culturing, vasopressor initiation, and second lactate measurement were 120.0 (60-300) minutes, 24 (12-240) minutes, 40 (20-60) minutes, and 24 (18-24) hours, respectively. The rate of compliance with tissue and organ perfusion follow-up in the first six hours was 0%. The rates of three- and six-hour sepsis bundle protocol compliance were both 0%. The ICU mortality rates for sepsis and septic shock were 22% and 78%, respectively. The ICU mortality rates for sepsis and septic shock were 22% and 78%, respectively. Conclusions The rate of compliance with sepsis bundle protocols was evaluated in Turkey for the first time and determined to be 0%.

Effects of Propofol versus Sevoflurane on Postoperative Pain and Neuroendocrine Stress Response in Oocyte Pickup Patients.

Background: Pain aggravates the autonomic response to stress and raises neuroendocrine stress hormone levels. We compared the effects of propofol and sevoflurane on postoperative pain and neuroendocrine stress hormones. A prospective, randomized, and controlled trial was conducted with 60 patients. Methods: We randomly allocated patients to groups P (remifentanil/propofol, n = 30) and S (remifentanil/sevoflurane, n = 30). Preoperative blood samples were taken to measure serum adrenocorticotropic hormone (ACTH), corticotropin-releasing hormone (CRH), glucagon, cortisol, aldosterone, and prostaglandin E2 (PGE2) levels. Intraoperatively and postoperatively, clinical parameters were monitored at different time points. The hormone levels were again measured in the follicular fluid and blood postoperatively. Result: Demographic data were similar. The preoperative serum aldosterone levels were significantly higher in group P (p=0.001). Preoperative and postoperative serum ACTH, glucagon, cortisol, and PGE2 levels were significantly different in group P (p=0.009, p=0.004, p=0.029, and p=0.002); serum ACTH, glucagon, and PGE2 levels increased while serum cortisol levels decreased postoperatively. In group S, serum CRH and aldosterone levels, both increased in the postoperative period compared to the preoperative (p=0.001, p=0.006). Postoperatively, glucagon and PGE2 levels were both higher in group P than group S (p=0.019, p=0.015). In postoperative follicular fluid, glucagon and PGE2 levels were higher in group P, while cortisol levels were higher in group S (p=0.001, p=0.007, and p=0.001). Conclusion: The effects of anesthetic agents were different. In group P, in the preoperative and postoperative evaluation, ACTH, glucagon, and PGE2 increased postoperatively, while cortisol decreased. In group S, aldosterone and CRH increased postoperatively. Glucagon and PG E2 were higher in group P than S, postoperatively.

Evaluation of the incidence, characteristics, and outcomes of pediatric chronic critical illness.

Our aim was to determine characteristics of children with chronic critical illness (CCI) admitted to the pediatric intensive care unit (PICU) of a tertiary care children's hospital in Turkey. The current study was a multicenter retrospective cohort study that was done from 2014 to 2017. It involved three university hospitals PICUs in which multiple criteria were set to identify pediatric CCIs. Pediatric patients staying in the ICU for at least 14 days and having at least one additional criterion, including prolonged mechanical ventilation, tracheostomy, sepsis, severe wound (burn) or trauma, encephalopathy, traumatic brain injury, status epilepticus, being postoperative, and neuromuscular disease, was accepted as CCI. In order to identify the newborn as a chronic critical patient, a stay in the intensive care unit for at least 30 days in addition to prematurity was required. Eight hundred eighty seven (11.14%) of the patients who were admitted to the PICU met the definition of CCI and 775 of them (87.3%) were discharged to their home. Of CCI patients, 289 (32.6%) were premature and 678 (76.4%) had prolonged mechanical ventilation. The total cost values for 2017 were statistically higher than the other years. As the length of ICU stay increased, the costs also increased. Interestingly, high incidence rates were observed for PCCI in our hospitals and these patients occupied 38.01% of the intensive care bed capacity. In conclusion, we observed that prematurity and prolonged mechanical ventilation increase the length of ICU stay, which also increased the costs. More work is needed to better understand PCCI.

Analgesic efficacy of the serratus anterior plane block in rib fractures pain: A randomized controlled trial.

BACKGROUND: Serratus anterior plane block (SAPB) was evaluated that in patients with the complaint of rib fracture pain in terms of total analgesic consumption and pain scores. METHOD: Sixty patients with rib fracture and NRS (Numeric Rating Scala) pain scores equal or greater than four were included in randomized controlled study. Patients were randomized to perform SAPB or control group. Primary outcome was total tramadol consumption in 24 h. Secondary outcomes were NRS scores (after Patient Controlled Analgesia (PCA) application 30 min, first, second, 4 th, 6 th, 12 th, 24 th hour), peripheral oxygen saturation (first and 24 th hour after PCA application), chronic pain. and complications. RESULTS: The total tramadol consumption significantly lower in group S (p = 0.02). NRS scores after 30 min, 1 h, 2 h, 4 h, 6 h, 12 h, and 24 h were significantly lower in group S than in group C (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p = 0.002, p = 0.026). The total number of patients who reported of chronic pain at rest and during effort was significantly lower in group SAPB than in group C (p = 0.006). Nine patients in group C were reported of pain, four of whom had pain at rest and five had pain during effort. One patient in group S was reported of pain during effort. CONCLUSION: This study demonstrated that SAPB, as part of multimodal analgesia in pain management due to rib fractures, is safe and effective in reducing acute pain.

Are high fresh gas flow rates necessary during the wash-in period in low-flow anesthesia?

In low-flow anesthesia (LFA), there is a wash-in period in which usually high fresh gas flow (FGF) rates are used to achieve the required initial concentration of anesthetic agent in the alveoli. The aim of this study was to compare the efficiency, safety and the consumption of desflurane in LFA using constant FGF (1 L/min) and conventional LFA using high FGF (4 L/min) during the wash-in period. Eighty patients, who were scheduled for elective surgery under general anesthesia with endotracheal intubation, were enrolled in the study. Wash-in was accomplished with 1 L/min FGF (50% O2, 50% air) and 18% desflurane in group 1; and by 4 L/min FGF (50% O2, 50% air) and 6% desflurane in group 2. Throughout the surgery, the vaporizer was adjusted to maintain 0.6 to 0.8 minimum alveolar concentration (MAC). The time required to reach 0.7 MAC was shorter in group 1 (160 seconds [135-181] vs 288 seconds [240-500], P < .001). In 6 patients in group 1 and 13 in group 2, vaporizer settings were adjusted to maintain 0.6 to 0.8 MAC (P = .048). Desflurane consumption in the first hour and total desflurane consumption were higher in group 2 (P < .001 and P = .012, respectively). The efficiency of anesthesia in both the first hour and in total was higher in group 1 (P < .001). It is safe, more efficient, and economical to use 1 L/min FGF during the wash-in period in LFA.

Retrospective Evaluation of Anesthetic Management in Cesarean Sections of Pregnant Women with Placental Anomaly.

BACKGROUND: In this study, patients who underwent cesarean section and had placenta previa and placenta accreta were examined and compared in terms of haemorrhagic indicators and perioperative anesthetic management. METHODS: A retrospective study was conducted in a university hospital in Kahramanmaras, Turkey. It included 95 pregnant women who had placental anomaly and underwent cesarean section between December 15, 2014, and February 15, 2016. RESULTS: The pregnant women were divided into two groups: Group P (previa) (n = 67) and Group A (accreta) (n = 28). The types of anesthesia administered were general anesthesia (GA), which was administered to 50 patients (74.6%) in Group P and 27 patients (96.4%) in Group A, and spinal anesthesia (SA), which was administered to 17 patients (25.4%) in Group P and one patient (3.6%) in Group A.. The mean blood loss was 685.82 ± 262.82 in Group P and 1582.14 ± 790.71 in Group A, and the given amount of crystalloid was higher in Group A with an average of 1628.57 ± 728.19 ml. The use of erythrocyte and fresh frozen plasma solution was higher in Group A than Group P. Eleven patients were intubated and taken to the Intensive Care Unit (ICU) in Group A. Postoperative mechanical ventilation duration was significantly higher in Group A (75.14 ± 43.84 h) (p < 0.001). ICU stay was longer in Group A with 2.80 ± 1.13 days. (p < 0.001). CONCLUSION: The intraoperative management and the availability of postoperative ICU conditions are important in placental anomalies cases. The communication between operation team with regard to the development of a standard protocol for these cases will be of great benefit in reducing morbidity and mortality.

Comparison of the efficacy of surgical tracheostomy and percutaneous dilatational tracheostomy with flexible lightwand and ultrasonography in geriatric intensive care patients.

AIM: To compare the applicability, technical difficulties and postoperative complications of surgical tracheostomy and percutaneous dilatational tracheostomy with the flexible lightwand + ultrasonography method applied because of prolonged intubation to geriatric patients in the intensive care unit. METHODS: A retrospective evaluation was made of 76 patients who received surgical tracheostomy (group 1) and 78 patients who received percutaneous dilatational tracheostomy (group 2). The patients were evaluated in respect of demographic data, duration of intubation, length of stay in the intensive care unit and discharge status, and after the intervention, the development of tube-related complications, early stage local complications and late-stage complications. RESULTS: The time from intubation to tracheostomy was determined as 22.73 ± 15.23 days in group 1 and 12.65 ± 7.64 days in group 2. The mortality rate of patients in group 1 was determined to be statistically significantly higher than that of group 2 (P = 0.048). When evaluated in respect to early and late complications, nine early- and seven late-stage complications developed in group 1, and three early- and three late-stage complications developed in group 2 (P = 0.05). In the evaluation of factors related to mortality, the time from intubation to tracheostomy (r = 0.249, P = 0.01) and the presence of a comorbidity (r = 0.325, P = 0.004) were determined to have a positive correlation with the development of mortality. CONCLUSION: Percutaneous dilatational tracheostomy with the flexible lightwand + ultrasonography technique is a safe, rapid and effective method with the advantage of management in respect to early complications, such as bleeding, and can be used safely in the geriatric patient population in intensive care conditions.

Comparison of quadratus lumborum block and caudal block for postoperative analgesia in pediatric patients undergoing inguinal hernia repair and orchiopexy surgeries: a randomized controlled trial.

BACKGROUND AND OBJECTIVES: Caudal epidural anesthesia is a widely used popular technique for postoperative analgesia but it has potential side effects and duration of analgesia is short. Quadratus lumborum block (QLB) was found to be an effective method for postoperative analgesia in lower abdominal surgeries. In this double-blind prospective randomized trial, we aimed to compare the postoperative analgesic efficacies of QLB and the caudal block in pediatric patients undergoing inguinal hernia repair and orchiopexy surgeries under general anesthesia. MATERIALS AND METHODS: After approval was obtained from the ethics committee, in this prospective randomized double-blind trial, 53 patients under general anesthesia undergoing inguinal hernia repair and orchiopexy surgeries randomly received caudal block or QLB. Demographic data, postoperative analgesic requirement, Face, Legs, Activity, Cry, and Consolability (FLACC) scores at 30 min, 1, 2, 4, 6, 12 and 24 hours, parent satisfaction scores and complications were recorded. RESULTS: The study included 52 patients, after excluding one patient because of a failed caudal block. There were no significant differences between the groups based on demographic data (p>0.05). The number of patients who required analgesics in the first 24 hours was significantly lower in QLB group (p=0.001). Postoperative 4, 6, 12 hours FLACC scores were significantly lower in the QLB group (p<0.001, p=0.001 and p<0.001, respectively). Parent satisfaction scores were higher in the QLB group (p=0.014). CONCLUSION: According to the results of this study, QLB can provide much more effective analgesia than caudal block without adjuvants in multimodal analgesia management of children undergoing inguinal hernia repair and orchiopexy surgeries.

Assessment of Somatic Support Process for Pregnant Brain Death Patients Occurring in a Transition Country Between Asia and Europe from Medical, Ethical, Legal and Religious Aspects.

In spite of the fact that brain death during pregnancy is not a common occurrence, it is an important ethical problem for all cultures and religions can have a significant influence on the donation decision after brain death. Therefore, this study aimed to present the case of a pregnant patient developing brain death which occurred in our intensive care unit and to compare the medical, ethical and legal problems relating to pregnant cases developing brain death with 24 cases in the literature. A 21-year-old 19-week pregnant case with gestational diabetes was monitored in the anesthesia intensive care unit and developed brain death due to intracranial mass and intraventricular hemorrhage. Though brain death is a situation well understood by organ transplant professionals, brain death developing in pregnant patients still involves many medical, ethical and legal problems.

The Effect of Flexible Lightwand and Ultrasonography Combination on Complications of the Percutaneous Dilatational Tracheostomy Procedure.

The aim of this study was to evaluate the effect of the flexible lightwand and ultrasonography (USG) combination on reducing the complications in percutaneous dilatational tracheostomy (PDT) opened with the forceps dilatation method. A retrospective examination was made of 138 patients between January 2014 and December 2018. Before starting to process, the anatomic structures of the patients were visualized with USG and the tracheostomy area was marked. Sedation and local anesthesia were applied to patients before the procedure, then the percutaneous tracheostomy was performed using the Griggs technique after confirmation of the tracheostomy localization defined with USG using the transillumination method with a flexible lightwand within an endotracheal tube. Complications that developed associated with the procedure were recorded. The mean age of the patients was 59.1±22.0 years and the mean length of stay in the intensive care unit was 42.3±35.5 days (range, 11-207 days). Overall, complications developed in 22 (15.6%) patients, of which 10.7% were early complications (1.4% related to the tube, 5.8% minor and 3.5% major complications). Tube- related complications were seen to develop in two patients. In the evaluation of the early minor complications, the most frequently seen complication was minor bleeding in 5.8% of the patients. No major vessel bleeding was determined in any patient in the early or late period. Of the late complications, the infection was seen to develop in four (2.8%) patients and stenosis in three (2.1%). The combination of flexible lightwand and USG in the PDT procedure minimized tube-related complications and contributed to the prevention of bleeding complications.

Severe burnout among critical care workers in Turkey.

OBJECTIVES: To determine the prevalence and risk factors for burnout in the intensive care units (ICU) staff in Turkey. Burnout is prevelant in physicians and nurses in the ICU worldwide. Most ICU workers with burnout plan to leave their professions. Frequent replacement of ICU staff increases cost and decreases the quality of care. Prevalence and risk factors of burnout in ICU staff in Turkey are largely unknown. METHODS: This is a cross-sectional study. Data were gathered using the Maslach Burnout Inventory (MBI) which was distributed during August 2018, among all 1161 ICU workers in Turkey. RESULTS: Burnout was detected in at least one subscale in 99% of participants and in all 3 subscales in 15% of the participants. Risk factors for emotional exhaustion included female gender (odds ratio [OR]=1.87 [95% CI: 1.26-2.78]; p less than 0.01), alternate-day shift (OR=3.93 [95% CI: 1.66-9.30]; p less than 0.01), and incidence of end of life care (OR=1.01 [95% CI: 1.00-1.03]; p less than 0.01). For depersonalization it included alternate-day shift (OR=2.22 [95% CI: 1.15-4.26]; p less than 0.05), incidence of end of life care (OR=1.02 [95% CI: 1.01-1.03]; p less than 0.01), and for reduced personal accomplishment it included incidence of end of life care (OR=0.97 [95% CI: 0.96-0.98]; p less than 0.01). Conclusion: The results indicated that ICU staff in Turkey had a high rate of burnout.

Low-flow anaesthesia with a fixed fresh gas flow rate.

During the wash-in period in low flow anaesthesia (LFA), high fresh gas flow is used to achieve the desired agent concentration. In this study, we aimed to evaluate the safety of fixed 1 L/min fresh gas flow desflurane anaesthesia in both the wash-in and maintenance periods in patients including the obese ones. 104 patients undergoing surgery under general anaesthesia were included. After endotracheal intubation, fresh gas flow was reduced to 1 L/min and the desflurane vaporizer was set at 18%. The time from opening the vaporizer to end-tidal desflurane concentration reaching 0.7 MAC was recorded (MAC 0.7 time). Throughout the surgery, hemodynamic variables, FIO2, MAC and BIS values were observed. MAC 0.7 time, BIS and MAC values at the start of surgery, number of adjustments in vaporizer settings, desflurane consumption were recorded. The average MAC 0.7 time was 2.9 ± 0.5 min. MAC and BIS values at the start of the surgery were 0.7 (0.6-0.8) and 39 ± 8.5 respectively. No individual patient had a BIS value above 60 throughout the surgery. Hemodynamic variables were stable and FIO2 did not fall below 30% in any patient. The number of adjustments in vaporizer settings was 56. Average desflurane consumption was 0.33 ± 0.05 mL/min. We demonstrated that LFA without use of initial high fresh gas flow during the wash-in period is an effective, safe and economic method which is easy to perform.

Extracorporeal carbondioxide removal (ECCO2R): case series and review of literature.

INTRODUCTION: Ventilation treatment has proven success in acute respiratory distress syndrome (ARDS), while it still remains a challenge to utilize it with lower tidal volumes especially in subjects with respiratory acidosis. The concept of supporting conventional ventilation with extracorporeal carbondioxide removal (ECCO2R) may contribute in adjusting respiratory acidosis consequent to tidal volume reduction in protective ventilation setting. This method allows an easier management of ARDS due to its less invasive approach. As shown by recent studies, ECCO2R can be preferred in subjects with exacerbation of chronic obstructive pulmonary disease (COPD) who are unresponsive to non-invasive ventilation (NIV). One of the most important aspects of this can be stated as the reduced rate of endotracheal intubation. MATERIALS AND METHODS: Subjects that were admitted to intensive care unit between March 2014 to November 2015 due to hypercapnic respiratory failure were treated using ECCO2R. RESULT: Over the study period, five patients received ECCO2R therapy. All subjects were managed with ECCO2R (Hemolung, A Lung Inc., Pittsburgh, USA) via a 15.5 FG percutaneously inserted cannula. CONCLUSIONS: We observed that ECCO2R is a promising method in the management of patients having COPD and can be used to protect lungs in patients with ARDS.

Efficacy of bispectral index monitoring for prevention of anestheticawareness and complications during oocyte pick-up procedure

Background/aim: This study was planned by considering that the use of bispectral index (BIS) monitoring ensures sufficient depth of anesthesia and avoids anesthetic awareness and patient movement in the oocyte pick-up (OPU) procedure.Materials and methods: Ninety-eight patients undergoing OPU were randomly divided into 2 groups as the control group (n = 48) and BIS group (n = 50). After propofol and remifentanil induction, the control group was given additional propofol according to reaction response, while the BIS group was given propofol at BIS values of 60 and above with the aim that BIS values be 40?60. Total procedure time, recovery time, patient movement, additional propofol consumption, total number of oocytes, and awareness during anesthesia were recorded. Results: Demographic data were similar in the two groups (P > 0.05 for all). The recovery time in the BIS group was significantly shorter compared to the control group (P < 0.001) while additional propofol consumption was found to be significantly lower (P < 0.001). Baseline BIS values fell compared to all other times after induction significantly (P < 0.001). No patient had anesthesia awareness.Conclusion: During the OPU procedure BIS monitoring is considered to prevent anesthesia awareness, intraoperative movement, and complications caused by insufficient anesthetic use as it ensures optimal doses of anesthetic agents used and early recovery.

Anesthesia Procedure for Congenital Insensitivity to Pain in a Child with Anhidrosis Syndrome: A Rare Case.

Congenital insensitivity to pain with anhidrosis (CIPA) syndrome is a neuropathy characterized by insensitivity to pain, impaired thermoregulation, anhidrosis, and mental retardation. A 9-year old boy with CIPA syndrome, underwent 2 operations for a calcaneal ulcer. During the first operation standard monitorization was performed. In the second operation, Bispectral Index (BIS) monitoring was added and temperature was monitored with an esophageal probe. In the first operation, in which anesthesia induction was applied with ketamine and midazolam, extremity movements with surgical stimuli were seen. Despite pain insensitivity, as extremity movements were seen with surgical stimuli, propofol was administered in the second operation. Throughout the operation, the BIS values varied from 19-58 and body temperature was measured as 36.1°C-36.9°C. In conclusion, despite the absence of pain sensitivity in CIPA syndrome cases, there is an absolute need for the administration of anesthesia in surgical procedures because of tactile hyperesthesia.

Ultrasound-guided versus surgical transversus abdominis plane block in obese patients following cesarean section: a prospective randomised study / Bloqueio cirúrgico do plano transverso abdominal versus guiado por ultrassom em pacientes obesas após cesárea: estudo prospectivo e randomizado

Abstract Background and objectives Ultrasound-guided transversus abdominis plane block demonstrated efficacy in providing post-operative analgesia by prolonging the time to first analgesic requirement and reducing the total analgesic consumption. The surgical transversus abdominis plane block, a novel technique, can be performed safely in obese patients in whom muscle layers cannot be sufficiently exposed. Here, we compared applicability, efficacy and complications of surgical transversus abdominis plane and ultrasound-guided transversus abdominis plane blocks in obese pregnant women following cesarean section under general anesthesia. Methods Seventy-five pregnant women with pre- and post-pregnancy body mass index > 30 were randomized and allocated into two groups: Ultrasound-guided transversus abdominis plane block (UT group; n = 38) and surgical TAP block (ST group; n = 37). Visual analogue scale scores at post-operative 0, 2, 6, 12 and 24 hours (h), time to first analgesic requirement, total analgesic consumption amount in 24 h, post-operative side effects, complications and patient satisfaction were recorded. Results and conclusions Age, American Society of Anesthesiologist score, operative duration, body mass index, mean time to first analgesic requirement and total analgesic consumption in 24 h were similar between groups, while significant differences in pre- and post-pregnancy body mass index were observed between groups. Block procedure durations were 7 and 10 minutes in ST and UT groups, respectively. No significant differences in visual analogue scale scores were observed between the groups at all times; itching and nausea was observed in one (UT group) and four (UT and ST groups) patients, respectively. Surgical transversus abdominis plane block was safe in obese pregnant patients and provided similar post-operative analgesia to ultrasound-guided transversus abdominis plane block.

Resumo Justificativa e objetivos O bloqueio do plano transverso abdominal (TAP) guiado por ultrassom (US) demonstrou eficácia no fornecimento de analgesia no pós-operatório ao prolongar o tempo até a primeira necessidade de analgésico e reduzir o consumo total de analgésico. O bloqueio TAP cirúrgico (uma nova técnica) pode ser realizado com segurança em pacientes obesas nas quais as camadas musculares não podem ser suficientemente expostas. Comparamos a aplicabilidade, a eficácia e as complicações do bloqueio TAP cirúrgico e do bloqueio TAP-US em gestantes obesas submetidas à cesárea sob anestesia geral. Método Setenta e cinco mulheres grávidas com índice de massa corporal (IMC) pré e pós-gravidez > 30 foram randomicamente alocadas em dois grupos: bloqueio TAP-US (Grupo TAP-US, n = 38) e bloqueio TAP cirúrgico (Grupo TAP-C, n = 37). Os escores da escala visual analógica (VAS) nos tempos 0, 2, 6, 12 e 24 horas de pós-operatório, o tempo até a primeira necessidade de analgésico, o consumo total de analgésico em 24 horas, os efeitos colaterais no pós-operatório, as complicações e a satisfação do paciente foram registrados. Resultados e conclusões Idade, estado físico ASA, tempo cirúrgico, IMC, média de tempo até a primeira necessidade de analgésico e consumo total de analgésico em 24 horas foram semelhantes entre os grupos, enquanto diferenças significativas foram observadas entre os grupos em relação ao IMC pré- e pós-gravidez. As durações dos procedimentos de bloqueio foram de 7 e 10 minutos nos grupos TAP-US e TAP-C, respectivamente. Não houve diferença significativa nos escores VAS entre os grupos em todos os momentos; prurido e náusea foram observados em um paciente (Grupo TAP-US) e em quatro (Grupo TAP-C), respectivamente. O bloqueio TAP cirúrgico foi seguro nas pacientes grávidas obesas e forneceu analgesia similar à do bloqueio TAP-US no pós-operatório.

Quadratus Lumborum Block Versus Transversus Abdominis Plane Block in Children Undergoing Low Abdominal Surgery: A Randomized Controlled Trial.

BACKGROUND AND OBJECTIVES: Truncal blocks have a place within multimodal analgesia techniques in abdominal surgery. The quadratus lumborum block is a new abdominal truncal block used for somatic analgesia of both the upper and lower abdomen. In this prospective, double-blind, randomized study, we aimed to compare quadratus lumborum block and transversus abdominis plane block in pediatric patients undergoing lower abdominal surgery. METHODS: Fifty-three children undergoing unilateral inguinal hernia repair or orchiopexy surgery were randomized into 2 groups: transversus abdominis plane block and quadratus lumborum block. All blocks were performed under general anesthesia before surgery. Pain levels were assessed using an FLACC (Face, Legs, Activity, Cry, Consolability) scale. RESULTS: The study included 50 patients, after excluding 3 patients who were not eligible. The number of patients who required analgesia in the first 24 hours postoperatively was significantly lower in the quadratus lumborum block group (P < 0.05). In the quadratus lumborum block group, the postoperative 30-minute and 1-, 2-, 4-, 6-, 12-, and 24-hour FLACC scores were lower compared with those of the transversus abdominis plane block group (P < 0.05). Parent satisfaction scores were higher in the quadratus lumborum block group (P < 0.05). CONCLUSIONS: The results of this study showed that in pediatric patients undergoing unilateral inguinal hernia repair or orchiopexy the quadratus lumborum block provided longer and more effective postoperative analgesia compared with the transversus abdominis plane block. CLINICAL TRIALS REGISTRATION: The trial was registered prospectively at clinicaltrials.gov (NCT02715999).

Bloqueio cirúrgico do plano transverso abdominal versus guiado por ultrassom em pacientes obesas após cesárea: estudo prospectivo e randomizado.

BACKGROUND AND OBJECTIVES: Ultrasound-guided transversus abdominis plane block demonstrated efficacy in providing post-operative analgesia by prolonging the time to first analgesic requirement and reducing the total analgesic consumption. The surgical transversus abdominis plane block, a novel technique, can be performed safely in obese patients in whom muscle layers cannot be sufficiently exposed. Here, we compared applicability, efficacy and complications of surgical transversus abdominis plane and ultrasound-guided transversus abdominis plane blocks in obese pregnant women following cesarean section under general anesthesia. METHODS: Seventy-five pregnant women with pre- and post-pregnancy body mass index>30 were randomized and allocated into two groups: Ultrasound-guided transversus abdominis plane block (UT group; n=38) and surgical TAP block (ST group; n=37). Visual analogue scale scores at post-operative 0, 2, 6, 12 and 24hours (h), time to first analgesic requirement, total analgesic consumption amount in 24h, post-operative side effects, complications and patient satisfaction were recorded. RESULTS AND CONCLUSIONS: Age, American Society of Anesthesiologist score, operative duration, body mass index, mean time to first analgesic requirement and total analgesic consumption in 24h were similar between groups, while significant differences in pre- and post-pregnancy body mass index were observed between groups. Block procedure durations were 7 and 10minutes in ST and UT groups, respectively. No significant differences in visual analogue scale scores were observed between the groups at all times; itching and nausea was observed in one (UT group) and four (UT and ST groups) patients, respectively. Surgical transversus abdominis plane block was safe in obese pregnant patients and provided similar post-operative analgesia to ultrasound-guided transversus abdominis plane block.
