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.

Abstract Background: Endotracheal intubation (ETI), which is the gold standard in coronary artery bypass grafting (CABG), may cause myocardial ischaemia by disturbing the balance between haemodynamic changes and oxygen supply and consumption of the myocardium as a result of sympathetic stimulation. In this study, we aimed to compare two different videolaryngoscopes (C-MAC and Airtraq) in the hemodynamic response to ETI. Methods: Fifty ASA II-III CABG surgery patients were randomly assigned to C-MAC or Airtraq. The hemodynamic data included arterial blood pressure [systolic (SAP), diastolic (DAP) and mean (MAP)] and heart rate (HR) and were recorded at six different points in time: before laryngoscopy-T1, during laryngoscopy-T2, immediately after intubation-T3, and 3 (T4), 5 (T5) and 10 (T6) minutes after intubation. Intraoperative complications were recorded. Patients were questioned about postoperative complications 2 and 24hours following extubation. Results: The hemodynamic response to ETI was significantly greater with C-MAC. The increase in HR started with the laryngoscopy procedure, whereas increases in SAP, DAP, and MAP started immediately after ETI (p = 0.024; p = 0.012; p = 0.030; p = 0.009, respectively). In group analyses, T1-T2, T2-T3 and T1-T3 comparisons did not show any significant differences in HR with Airtraq. However, with C-MAC, HR after intubation increased significantly compared to the pre-laryngoscopy values (T1-T3) (p = 0.004). The duration of laryngoscopy was significantly reduced with C-MAC (p < 0.001), but the duration of intubation and total intubation were similar (p = 0.36; p = 0.79). Conclusions: Compared to C-MAC, the hemodynamic response to ETI was less with Airtraq. Thus, Airtraq may be preferred in CABG patients for ETI.

Resumo Introdução: A cirurgia de quadril é uma cirurgia de grande porte que causa dor intensa no pós-operatório. Embora a dor durante o repouso seja consideravelmente reduzida, a mobilização é importante em termos de complicações tromboembólicas. O bloqueio doquadrado lombar é uma técnica analgésica regional que bloqueia os ramos nervosos de T6-L3. Esse bloqueio pode fornecer analgesia adequada e reduzir o consumo de opioides após cirurgiasde quadril. Relato de caso: Realizamos o bloqueio contínuo do quadrado lombar tipo 3 em dois pacientes submetidos à artroplastia de quadril. Durante as 24 hs de pós-operatório foram registrados os escores de dor, o consumo de anestésicos locais em analgesia controlada pelo paciente e a necessidade de analgésicos adicionais. Em dois pacientes, os escores de dor pós-operatória foram < 6 durante o repouso e fisioterapia. O paciente foi mobilizado no período pós-operatório imediato, sem precisar de analgésico opioide adicional e sem fraqueza muscular. Discussão: O bloqueio contínuo do quadrado lombar pode ser usado para aliviar a dor aguda no pós-operatório de cirurgia de quadril porque fornece anestesia unilateral sem fraqueza muscular.

Abstract Introduction: Hip surgery is a major surgery that causes severe postoperative pain. Although pain during rest is usually considerably reduced mobilization is important in terms of thromboembolic complications. The quadratus lumborum block is a regional analgesic technique that blocks T6-L3 nerve branches. This block may provide adequate analgesia and reduce opioid consumption after hip surgery. Case report: We performed continuous quadratus lumborum type 3 block in two patients who underwent hip arthroplasty. Postoperative 24-h pain scores, local anesthetic consumptions on patient-controlled analgesia and additional analgesic requirement were recorded. In two patients, postoperative pain scores were less than 6 during rest and physiotherapy. Patient was mobilized in the early postoperative period without additional opioid analgesic requirement and without muscle weakness. Discussion: Continuous quadratus lumborum block may be used to relieve postoperative acute pain in hip surgery because it provides one-sided anesthesia without muscle weakness.
