Summary

This study looks at how lying in a head-up position (Reverse Trendelenburg) after laparoscopic gallbladder surgery affects oxygen levels in the blood. Researchers will compare obese and non-obese patients and also use the STOP-BANG score to check for sleep apnea risk. The goal is to better understand which patients might need extra oxygen support after surgery.
