Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This single-center, prospective, randomized, assessor-blinded clinical trial aims to compare the effects of sevoflurane and desflurane anesthesia on intraoperative mechanical power in adult patients undergoing elective laparoscopic cholecystectomy. Mechanical power will be measured at three standardized time points using a validated formula, and secondary outcomes include driving pressure values and early postoperative respiratory complications (desaturation, laryngospasm, bronchospasm, cough).

PREVENTION

Blinding Strategy

SINGLE

Outcome Assessors
Participants and postoperative outcome assessors are masked to group allocation. The anesthesia team administering sevoflurane or desflurane is not blinded, but all intraoperative data collectors and postoperative evaluators remain blinded to the inhalational agent used. Randomization is performed using sealed opaque envelopes to maintain allocation concealment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm S- Sevoflurane Group

Maintenance of general anesthesia with sevoflurane 2% during laparoscopic cholecystectomy. Mechanical power is measured at three intraoperative time points using standardized ventilator settings.

Group Type EXPERIMENTAL

Sevoflurane

Intervention Type DRUG

General anesthesia will be maintained with sevoflurane at 2% concentration in patients assigned to the Sevoflurane Group (Group S). Standardized ventilator settings will be applied for all participants, and mechanical power will be measured at three intraoperative time points while sevoflurane is used as the sole maintenance inhalational agent.

Arm D-desflurane group

Maintenance of general anesthesia with desflurane 6% during laparoscopic cholecystectomy. Mechanical power is measured at three standardized intraoperative time points under identical ventilator settings.

Group Type EXPERIMENTAL

Desflurane

Intervention Type DRUG

Maintenance of general anesthesia with desflurane 6% during laparoscopic cholecystectomy. Mechanical power is measured at three intraoperative time points using standardized ventilator settings.
