Effect of recorded mother's voice on emergence delirium in pediatric patients: a systematic review with meta-analysis

Abstract Objective: Emergence delirium is a common complication in children. Recorded mother's voice, as a non-pharmacological measure, is increasingly used to prevent the emergence of delirium in pediatric patients, but sufficient evidence is still needed to prove its efficacy. Methods: Embase, PubMed, Cochrane Library, Web of Science, CINAHL, and Sinomed databases were searched for randomized controlled trials exploring the efficacy of recorded mother's voice in preventing the emergence of delirium in pediatric patients undergoing general anesthesia. The original data were pooled for the meta-analysis with Review Manager 5.4.1. This study was conducted based on the Cochrane Review Methods. Results: Eight studies with 724 children were included in the analysis. Recorded mother's voice reduced the incidence of emergence delirium when compared with either no voice (RR: 0.45; [95 % CI, 0.34 - 0.61]; p < 0.01; I2 = 7 %) or stranger's voice (RR: 0.51; [95 % CI, 0.28 - 0.91]; p = 0.02; I2 = 38 %) without increasing other untoward reactions. In addition, it shortened the post-anesthesia care unit stay time when compared with no voice (MD = -5.64; [95 % CI, -8.43 to -2.58]; p < 0.01, I2 = 0 %), but not stranger's voice (MD = -1.23; [95 % CI, -3.08 to 0.63]; p = 0.19, I2 = 0 %). It also shortened the extubation time and reduced the incidence of postoperative rescue analgesia. Conclusion: The current analysis indicated that recorded mother's voices could reduce the incidence of emergency delirium, shorten post-anesthesia care unit stay time and extubation time, and decrease the incidence of postoperative rescue analgesia in children.

EVALUATION OF INTRAOPERATIVE PAIN OCCURRENCE AND NEED FOR SUPPLEMENTAL ANESTHESIA DURING EMERGENCY DENTAL CARE

Aims: This study aimed to evaluate the intraoperative pain (IOP) occurrence in situations of symptomatic irreversible pulpitis (SIP) and symptomatic apical periodontitis (SAP). Materials and Methods: Patients who sought emergency care presenting a diagnosis of SIP or SAP were included. IOP was measured with a Visual Analogue Scale (VAS) after five minutes of local anesthesia, during access to the pulp chamber, root canal exploration and at the end of procedures. In cases where pain was reported during treatment, supplementary anesthesia was performed. Pain scores were recorded and analyzed using a generalized estimating equation model with posthoc comparisons. Results: 56 patients were included. 35 had a diagnosis of SIP; and 21 a diagnosis of SAP. Mean preoperative pain scores for SAP and SIP were 6.69 (±1.54) and 6.39 (±1.48), respectively (p>0.05). In patients with SIP, significant differences were observed between: preoperative scores and other time points; scores after five minutes of local anesthesia and other time points; scores during pulp chamber access and at the end of procedures; and scores during root canal exploration and at the end of procedures (p<0.05). In patients with SAP, significant differences were observed between preoperative pain scores with all other time points (p<0.05). Chi-square test indicated an association between diagnosis and the need for supplementary anesthesia (p<0.05). Conclusions: In conclusion, there is a strong relationship between reduction of moderate/severe pain after application of local anesthesia. The need for supplemental anesthesia is significantly associated to the diagnosis of symptomatic irreversible pulpitis.

The duration-dependent and sex-specific effects of neonatal sevoflurane exposure on cognitive function in rats

Clinical studies have found that neonatal sevoflurane exposure can increase the risk of cognitive dysfunction. However, recent studies have found that it can exhibit neuroprotective effects in some situations. In this study, we aimed to explore the effects of sevoflurane neonatal exposure in rats. A total of 144 rat pups (72 males and 72 females) were assigned to six groups and separately according to sevoflurane exposure of different times on the seventh day after birth. Blood gas analysis and western blot detection in the hippocampus were conducted after exposure. The Morris water maze test was conducted on the 32nd to 38th days after birth. The expression of PSD95 and synaptophysin in the hippocampus was detected after the Morris water maze test. We found that neonatal exposure to sevoflurane promoted apoptosis in the hippocampus, and Bax and caspase-3 were increased in a dose-dependent manner. The 2-h exposure had the greatest effects on cognitive dysfunction. However, with the extension of exposure time to 6 h, the effects on cognitive function were partly compensated. In addition, sevoflurane exposure decreased synaptogenesis in the hippocampus. However, as the exposure time was extended, the suppression of synaptogenesis was attenuated. In conclusion, neonatal sevoflurane exposure exhibited duration-dependent effects on cognitive function via Bax-caspase-3-dependent apoptosis and bidirectional effects on synaptogenesis in rats.

Metahemoglobinemia congénita. Reporte de caso / Congenital Methemoglobinemia. A Case Report

Resumen La metahemoglobinemia ocasionalmente causa cianosis, particularmente cuando es congénita. Debido a sus vías enzimáticas deficientes y a la disminución de la capacidad de transporte de oxígeno, para los pacientes con metahemoglobinemia congénita es importante evitar la exposición a agentes oxidantes. A continuación, presentamos un paciente pediátrico con metahemoglobinemia congénita no diagnosticada preoperatoriamente que fue sometido a cateterismo con diagnóstico probable de hipertensión pulmonar bajo anestesia general. El paciente pediátrico era un niño de 10 años que presentaba una lectura de oximetría de pulso (SpO2) 92% antes de la inducción de la anestesia. La metahemoglobinemia se sospechó intraoperatoriamente por primera vez debido a un desajuste de la SpO2 de la oximetría de pulso digital y la SaO2 (saturación arterial de oxígeno), y luego se confirmó mediante múltiples longitudes de onda con la CO-oximetría. Se discuten la fisiopatología, etiología, manifestaciones clínicas, consideraciones anestésicas y opciones de tratamiento de la metahemoglobinemia.

Abstract Methemoglobinemia occasionally causes cyanosis particularly in congenital methemoglobinemia. Avoidance of exposure to oxidizing agents is important for patients with congenital methemoglobinemia because of their deficient enzymatic pathways and decreased oxygen-carrying capacity. Here, we present a pediatric patient with preoperatively undiagnosed congenital methemoglobinemia who underwent catheterization with probably diagnosis of pulmonar hypertension under general anesthesia. The pediatric patient was a 10-year-old who displayed a low pulse oximetry reading of 92% prior to induction of anesthesia. Methemoglobinemia was first suspected intraoperatively because of a mismatch of SpO2 of finger pulse oximetry and SaO2 of arterial blood, and was later confirmed by multiplewavelength CO-oximetry. The pathophysiology, etiology, clinical manifestations, anesthetic considerations, and treatment options of methemoglobinemia are discussed.

Effects of dexmedetomidine-assisted general anesthesia on the hemodynamics and cognitive function in elderly patients undergoing painless enteroscopy / 中国药房

OBJECTIVE To investigate the effects of dexmedetomidine （DEX）-assisted general anesthesia on hemodynamics and cognitive function in elderly patients undergoing painless enteroscopy. METHODS From July 2020 to February 2022， 180 elderly patients undergoing painless enteroscopy in the outpatient operating room of the Second People’s Hospital of Jiaozuo were selected and divided into a control group （n＝90） and an observation group （n＝90） according to the random number table method. The control group was given routine general anesthesia （induced with sufentanil and propofol anesthesia， maintained with propofol anesthesia）， while the observation group was given DEX-assisted general anesthesia after preoperative preparation. The hemodynamic indexes [mean arterial pressure （MAP）， heart rate （HR）]， dosage of general anesthesia， awakening time， cognitive function [minimized mental status examination （MMSE）]， and the incidence of adverse drug reactions were compared between the two groups. RESULTS There was no significant difference in various indicators before anesthesia （T0） between 2 groups （P＞ 0.05）. Compared with T0， MAP and HR of the two groups were reduced significantly 10 minutes after anesthesia （T1）， at the time of enteroscope reaching the ileum and cecum （T2）， enteroscope withdrawal after the examination （T3）， and 10 minutes after surgery （T4）； but MAP and HR of the observation group at T1， T2， T3， and T4 were all higher than those of the control group （P＜0.05）. Compared with the control group， the dosage of general anesthesia and the recovery time in the observation group were significantly reduced or shortened， the MMSE scores at 1， 2 and 3 days after the operation were significantly increased， while the incidence of cognitive dysfunction and adverse reactions were significantly reduced （P＜0.05）. CONCLUSIONS DEX can effectively improve the hemodynamics and cognitive function of elderly patients undergoing painless enteroscopy， which is beneficial to reduce the dosage of general anesthesia， shorten recovery time， and has better safety.

Comparison of effects of transverse abdominis plane block and incision infiltration anesthesia on early postoperative recovery in patients undergoing thoracoscopic lung resection with general anesthesia / 中华麻醉学杂志

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.

Anesthesia management of children undergoing resection of pheochromocytoma and paraganglioma / 中华麻醉学杂志

Objective:To retrospectively analyze the anesthetic management characteristics of children undergoing resection of pheochromocytoma and paraganglioma (PPGL).Methods:The clinical data from patients undergoing resection of PPGL and confirmed histologically from January 1, 2010 to June 30, 2023 were retrospectively collected. The baseline characteristics, intraoperative conditions and postoperative complications were recorded.Results:The clinical data from 47 pediatric patients were analyzed. The overall incidence of hemodynamic instability events was 68% (32 cases). Lowering preoperative blood pressure to normal levels and the maximum diameter of tumor≥6 cm was helpful in reducing the incidence of the intraoperative hemodynamic instability events ( P<0.05). Postoperative hypotension developed in 7 cases, acute left heart failure in 1 case, arrhythmia in 1 case, adrenocortical insufficiency in 4 cases, and pulmonary infection in 13 cases. Conclusions:Thorough preoperative preparation, evidence-based anesthetic management, and meticulous postoperative vital sign monitoring can increase the perioperative safety for children undergoing resection of PPGL, thereby reducing the incidence of complications.

Bilateral ibSLN block was performed with 0.375% ropivacaine hydrochloride 2 ml.The tracheal extubation time, emergence time, development of cardiovascular events within 15 min after extubation, emergence agitation, Ramsay sedation score, Steward recovery score, visual analogue scale scores at 10 min after extubation and development of postoperative sore throat and hoarseness in postanesthesia care unit were recorded. Results:Compared with group C, the incidence of emergence agitation, Ramsay sedation score, visual analogue scale scores and sore throat were significantly decreased, the incidence of hoarseness was increased ( P<0.05), and no significant change was found in the extubation time, emergence time and Steward recovery score in group U( P>0.05). No hypertension, hypotension, tachachycardia and bradycardia were found in two groups. Conclusions:Ultrasound-guided ibSLN block can improve the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.

Efficacy of esketamine combined with different doses of remimazolam for induction of general anesthesia in pediatric patients / 中华麻醉学杂志

Objective:To evaluate the efficacy of esketamine combined with different doses of remimazolam for induction of general anesthesia in pediatric patients.Methods:One hundred and sixty pediatric patients of either sex, aged 3-6 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, with body mass index of 13-20 kg/m 2, undergoing elective general anesthesia under a laryngeal mask, were divided into 4 groups ( n=40 each) by the random number table method: esketamine combined with propofol group (KP group) and esketamine combined with different doses of remimazolam group (0.2, 0.3, 0.4 mg/kg) groups (KR1 group, KR2 group, KR3 group). Esketamine 0.8 mg/kg was intravenously injected in the preanesthesia room. After entering the operating room, propofol 2.5 mg/kg was intravenously injected in KP group, and remimazolam 0.2, 0.3 and 0.4 mg/kg were intravenously injected in KR1, KR2 and KR3 groups, respectively. When the child lost consciousness and the Modified Observer′s Assessment of Alertness/Sedation Scale score<1, sufentanil and mevacurium were intravenously injected. When the Modified Observer′s Assessment of Alertness/Sedation Scale score≥1, rescue sedation was performed, and 3 min later the laryngeal mask airway was inserted. The onset time of sedation, response to laryngeal mask airway placement, rescue sedation, hypotension, tachycardia, bradycardia, bucking, hiccup, injection pain and apnea were recorded, and the increase rate of perfusion index (PI) was calculated. Results:No response to laryngeal mask implantation occurred in the four groups. Compared with KP group, the onset time of sedation was significantly prolonged, the incidence of hypotension, bradycardia, injection pain and apnea was decreased, the incidence of tachycardia was increased, and the increase rate of PI was decreased in KR1, KR2 and KR3 groups, and the rate of rescue sedation and incidence of bucking were increased in KR1 and KR2 groups ( P<0.05). Compared with KR1 group, the onset time of sedation was significantly shortened in KR2 group and KR3 group, and the rate of rescue sedation and incidence of bucking were decreased in KR3 group ( P<0.05). Compared with KR2 group, the onset time of sedation was significantly shortened, and the rate of rescue sedation was decreased in KR3 group ( P<0.05). There was no significant difference in the increase rate of PI, hypotension, bradycardia, tachycardia, injection pain and apnea among KR1, KR2 and KR3 groups ( P>0.05). There was no significant difference in the incidence of hiccup among the four groups ( P>0.05). Conclusions:Esketamine 0.8 mg/kg combined with remimazolam 0.4 mg/kg can be safely and effectively used for anesthesia induction and has milder inhibition of respiration and circulation as compared with esketamine combined with propofol in pediatric patients.

Application of Magnetic Resonance Imaging and Transrectal Ultrasound Image Fusion Targeted Transperineal Biopsy Technique Using Electromagnetic Needle Tracking Under Local Anaesthesia / 肿瘤防治研究

Objective To explore the effect and safety of magnetic resonance imaging and transrectal ultrasound (mpMRI-TRUS) image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia. Methods We retrospectively analyzed the clinical and pathological data of 81 patients with mpMRI-TRUS image fusion targeted transperineal prostate biopsy using electromagnetic needle tracking under local anesthesia. Visual analog scale (VAS) and visual numeric scale (VNS) were used to evaluate the pain level and satisfaction of patients during prostate biopsy (VAS-1 and VNS-1), one hour after puncture (VAS-2 and VNS-2), and one day after surgery (VAS-3 and VNS-3). The perioperative clinical data and tumor positive rate of postoperative biopsy were recorded. Results The average prostate volume of 81 patients was 53.39±29.46 cm3. The PSA values of patients with PI-RADS scores of 2, 3, 4, and 5 were 9.14±2.31, 9.95±4.10, 14.77±6.36, and 32.17±24.39 ng/ml, respectively. The scores of VAS-1, VAS-2, and VAS-3 were 1.70±0.73, 1.16±0.58, and 0.53±0.55, respectively; the scores of VNS-1, VNS-2, and VNS-3 were 2.74±0.44, 3.69±0.46, and 3.84±0.37, respectively. The average surgical time was 17.47±3.44 minutes. Postoperative pathological results showed that the tumor positive rate of targeted prostate biopsy was 64.20%. According to the PI-RADS score for subgroup analysis, the tumor positive rates of patients with PI-RADS scores of 2, 3, 4, and 5 were 21.43%, 44.44%, 61.11%, and 96.77%, respectively. After transperineal prostate biopsy, gross hematuria occurred in 19.75% patients, and urinary retention occurred in 3.70%. The latter were relieved after symptomatic treatment. All patients did not experience complications, such as perineal puncture area hematoma, urinary tract infection, hematospermia, hematoma in perineal puncture area, urinary tract infection, hematospermia, vagus nerve reaction, or septic shock. Conclusion For suspected prostate cancer patients, mpMRI-TRUS image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia is a feasible and easily tolerated surgical procedure. It has good safety and high tumor positive-detection rate, indicating that this technique is worthy of further clinical promotion and application.

ObjectiveTo investigate risk factors for postoperative sore throat in patients with double-lumen endotracheal intubation. MethodsThe data used in this post-hoc analysis were prospectively collected from a randomized， controlled trial. Age from 18 to 65 years old， ASAI-Ⅲ patients undergoing general anesthesia with a double-lumen endotracheal tube were enrolled. The perioperative data collected retrospectively were as follows： gender， age， smoking history， endotracheal tube diameter， duration of endotracheal tube， dose of Sufentanil， use of Flurbiprofen Axetil， cough after extubation， etc..Dynamometer was applied to assess extubation force. According to occurrence of postoperative sore throat， patients were divided into two groups： those who experienced sore throats and those who did not. Comparative analysis and multivariate logistic regression analysis were performed to screen the risk factors. ROC curve was used for predicting the predictive value of risk factors. ResultsAmong the 163 patients ， 74 （45.4%） had postoperative sore throat vs 89 （54.6%） not had. Multivariate logistic regression showed female ［OR95%CI=3.83（1.73， 8.50）， P=0.000 1］ and extubation force ［OR95%CI=1.78（1.45， 2.17）， P＜0.001］ were independent risk factors for postoperative sore throat. AUC value showed the extubation force was 0.773［95%CI（0.701， 0.846）， P＜0.001］. Youden index was 0.447， and the cut-off valve of extubation force was 13N. ConclusionFemale and extubation force were risk factors for sore throat in patients with double lumen endotracheal intubation.
