Comparison of the Analgesic Efficacy of Erector Spinae Plane Block, Paravertebral Block and Quadratus Lumborum Block for Pelvi-ureteric Surgeries: A Randomized Double-Blind, Noninferiority Trial.

Background: Effective postoperative analgesia enhances the patient's comfort and facilitates early mobilization and recovery.

Objective: This study compared the analgesic efficacy of the erector spinae plane block (ESPB), thoracic paravertebral block (TPVB), and quadratus lumborum block (QLB) for pelvi-ureteric surgeries. The primary outcome measure in the study was the total morphine consumption during the first 48 hours following the operation.

Laparoscopic assisted versus ultrasound guided transversus abdominis plane block in laparoscopic bariatric surgery: a randomized controlled trial.

Background: Transversus abdominis plane block (TAPB) guided by laparoscopy and ultrasound showed promise in enhancing the multimodal analgesic approach following several abdominal procedures. This study aimed to compare the efficacy and safety between Laparoscopic (LAP) TAP block (LTAP) and ultrasound-guided TAP block (UTAP) block in patients undergoing LAP bariatric surgery.

Patients And Methods: This non-inferiority randomized controlled single-blind study was conducted on 120 patients with obesity scheduled for LAP bariatric surgeries.

Effects of tidal volume challenge on the reliability of plethysmography variability index in hepatobiliary and pancreatic surgeries: a prospective interventional study.

Background: The plethysmography variability index (PVI) is a non-invasive, real-time, and automated parameter for evaluating fluid responsiveness, but it does not reliably predict fluid responsiveness during low tidal volume (V) ventilation. We hypothesized that in a 'tidal volume challenge' with a transient increase in tidal volume from 6 to 8 ml Kg, the changes in PVI could predict fluid responsiveness reliably.

Method: We performed a prospective interventional study in adult patients undergoing hepatobiliary or pancreatic tumor resections and receiving controlled low V ventilation.

The role of dexmedetomidine as an adjuvant for high-thoracic erector spinae plane block for analgesia in shoulder arthroscopy; a randomized controlled study.

Background: Management of postoperative pain after shoulder arthroscopy is an important issue. Dexmedetomidine, as an adjuvant, improves nerve block efficacy and decreases postoperative consumption of opioids. As a result, we designed this study to determine if adding dexmedetomidine to an erector spinae plane block (ESPB) that is guided by ultrasound (US) is beneficial for treating immediate postoperative pain following shoulder arthroscopy.
