Overview

Prospective observational study investigates the impact of analgesia techniques on pulmonary function post-surgery, indicating significant benefits of block techniques.

Key Points

  • The study aims to assess how two analgesia techniques affect pulmonary function after laparoscopic cholecystectomy.
  • Prospective observational study with 102 patients aged 18–65 years undergoing elective laparoscopic cholecystectomy.
  • Patients divided into three groups: Subcostal block, EOIPB, and Control, with final analysis on 90 patients.
  • Pulmonary function, pain scores, opioid use, and recovery quality were evaluated pre- and postoperatively.
  • Postoperative pulmonary function significantly declined in all groups, more so in the Control group (p < 0.05).
  • Predicted FEV 1 was lower in the Subcostal group compared to the EOIPB group at hour 1 post-surgery (p = 0.003).
  • Pain scores and opioid consumption were significantly lower in block groups versus Control (p < 0.05), while QoR-15 scores were higher in block groups (p < 0.05).
