Comparison of perioperative analgesic effectiveness of ultrasound-guided erector spinae plane block and transversus abdominis plane block in patients undergoing laparoscopic nephrectomy.

Objectives: In this study, we aimed to compare the efficacy of two regional anesthesia methods, transversus abdominis plane (TAP) block and erector spinae plane (ESP) block, for intraoperative and postoperative pain relief in patients undergoing laparoscopic nephrectomy.

Methods: Fifty patients aged 18-80 years with American Society of Anesthesiologists (ASA) classification I-II scheduled for elective laparoscopic nephrectomy were included after ethical approval and informed consent. Patients were randomly assigned to either Group TAP (receiving TAP block) or Group ESP (receiving ESP block).

Comparison of Intra- and postoperative effectiveness of erector spinae plane block and patient controlled analgesia in patients undergoing coronary artery bypass grafting surgery.

The aim of our study was to compare bilateral erector spinae plane block (ESPB) efficacy on pain management with patient controlled analgesia (PCA) during the perioperative period in patients scheduled for coronary artery bypass grafting (CABG). After ethics committee approval (2019-7/31 dated 09.04.

Peri-operative blood transfusion in elective major surgery: incidence, indications and outcome - an observational multicentre study.

Background: Patients' demographic and epidemiological characteristics, local variations in clinicians' knowledge and experience and types of surgery can influence peri-operative transfusion practices. Sharing data on transfusion practices and recipients may improve patients' care and implementation of Patient Blood Management (PBM).

Materials And Methods: This was a multicentre, prospective, observational, cross-sectional study that included 61 centres.

Induction of anesthesia in coronary artery bypass graft surgery: the hemodynamic and analgesic effects of ketamine.

Objective: The aim of this prospective, randomized study was to evaluate the hemodynamic and analgesic effects of ketamine by comparing it with propofol starting at the induction of anesthesia until the end of sternotomy in patients undergoing coronary artery bypass grafting surgery.

Introduction: Anesthetic induction and maintenance may induce myocardial ischemia in patients with coronary artery disease. A primary goal in the anesthesia of patients undergoing coronary artery bypass grafting surgery is both the attenuation of sympathetic responses to noxious stimuli and the prevention of hypotension.

Preoperative multiple-injection thoracic paravertebral blocks reduce postoperative pain and analgesic requirements after video-assisted thoracic surgery.

Objective: The hypothesis was tested that preoperative multiple-injection thoracic paravertebral blocks reduce opioid requirements and promote early ambulation after video-assisted thoracic surgery procedures.

Design: Prospective, randomized, controlled, blinded study.

Setting: Single-university hospital.

Combination of intrathecal morphine and remifentanil infusion for fast-track anesthesia in off-pump coronary artery bypass surgery.

Objective: The purpose of this study was to assess the combination of intrathecal morphine and remifentanil infusion with isoflurane in off-pump coronary artery surgery, with a focus on postoperative analgesia and fast-tracking.

Design: Prospective, randomized, controlled, blinded clinical study.

Setting: University hospital.

Comparison of lumbar epidural tramadol and lumbar epidural morphine for pain relief after thoracotomy: a repeated-dose study.

Objective: The purpose of this study was to compare lumbar epidural morphine and lumbar epidural tramadol with respect to onset and duration of analgesia, analgesic efficacy, and drug-related side effects after muscle-sparing thoracotomy.

Design: Prospective, randomized, double-blind, clinical study.

Setting: Single university hospital.

Comparison of analgesic effects of morphine, fentanyl, and remifentanil with intravenous patient-controlled analgesia after cardiac surgery.

Objective: The purpose of this study was to compare the analgesic effects of remifentanil with 2 other opioid agents, morphine and fentanyl, after cardiac surgery.

Design: Prospective, randomized, and double-blinded study.

Settings: This study was performed at Uludag University hospital.

Declines in serum free and bound choline concentrations in humans after three different types of major surgery.

We examined the changes in circulating choline status in humans in response to major surgery by measuring serum free and phospholipid-bound choline concentrations before, during and 1-72 h after total abdominal hysterectomy, off-pump coronary artery graft surgery or brain tumor surgery. Preoperatively, the mean serum free and phospholipid-bound choline concentrations in patients scheduled for abdominal hysterectomy (n = 26), off-pump coronary artery grafting surgery (n = 34) or brain tumor surgery (n = 24) were 12.3 +/- 0.
