Randomized Controlled Trial[Efficacy of ultrasound-guided erector spinae plane block for analgesia after laparoscopic cholecystectomy: a randomized controlled trial].
The primary aim of this study is to assess the effect of ultrasoung-guided erector spinae block on postoperative opioid consumption after laparoscopic cholecystectomy. The secondary aims are to assess the effects of erector spinae plane block on intraoperative fentanyl need and postoperative pain scores. ⋯ Bilateral US-ESP block provided significant reduction in postoperative opioid consumption, intraoperative fentanyl need and postoperative pain scores of patients undergoing laparoscopic cholecystectomy.

Randomized Controlled Trial Comparative Study[Comparison of pressure-controlled volume-guaranteed ventilation and volume-controlled ventilation in obese patients during gynecologic laparoscopic surgery in the Trendelenburg position].
The aim of this study was to investigate the efficacy of the pressure-controlled, volume-guaranteed (PCV-VG) and volume-controlled ventilation (VCV) modes for maintaining adequate airway pressures, lung compliance and oxygenation in obese patients undergoing laparoscopic hysterectomy in the Trendelenburg position. ⋯ The PCV-VG mode of ventilation limited the peak inspiratory pressure, decreased the driving pressure and increased the dynamic compliance compared to VCV in obese patients undergoing laparoscopic hysterectomy. PCV-VG may be a preferable modality to prevent barotrauma during laparoscopic surgeries in obese patients.
