Effects of Neostigmine-dose on Diaphragmatic Dynamics

Summary

The goal of this Randomized Clinical Trial is to compare the postoperative diaphragmatic excursion between patients receiving half-dose neostigmine (0.04 mg/kg) and those receiving full-dose neostigmine (0.08 mg/kg) for neuromuscular blockade reversal. The main questions it aims to answer are: * Does half-dose neostigmine result in similar postoperative diaphragmatic excursion compared to full-dose neostigmine? * Does half-dose neostigmine result in similar diaphragmatic thickening fraction compared to full-dose neostigmine? Researchers will compare patients receiving half-dose neostigmine to those receiving full-dose neostigmine to see if there are differences in postoperative diaphragmatic function, respiratory complications, and recovery. Participants will: * Undergo elective laparoscopic cholecystectomy. * Receive either half-dose or full-dose neostigmine for neuromuscular blockade reversal.
