The Impact of Anterior Abdominal Wall Tissue Oxygenation During Pneumoperitoneum of Regional Anesthesia Methods

Not Applicable

• Conditions: Laparoscopy; Regional Anesthesia; Abdominal Wall
• Interventions: Device: regional oxymetry probe; Procedure: Quadratus Lumborum block; Procedure: Thoracic Epidural block

• Registration Number: NCT03652506
• Lead Sponsor: Bursa Yüksek İhtisas Education and Research Hospital

Brief Summary

During laparoscopic surgery, the abdomen is inflated with carbon dioxide for abdominal imaging and increased intraabdominal pressure affects intraabdominal structures and abdominal wall.

Detailed Description

The investigators aimed to investigate the effects of regional anesthesia methods administered during laparoscopic cholecystectomy on abdominal wall oxygenation and postoperative pain scores.
