Isoflurane versus sevoflurane effects on oxidative stress during laparoscopic gallbladder removal

A Comparative Study Between the Impact of Isoflurane and Sevoflurane on Oxidative Stress in Patients Undergoing Laparoscopic Cholecystectomy

Not applicable Interventional Ain Shams University · NCT07152912

What this trial studies

Adults scheduled for elective laparoscopic cholecystectomy will receive general anesthesia with either isoflurane or sevoflurane according to the protocol. Blood samples will be taken before and after anesthesia and surgery to measure markers of oxidative stress and inflammation. The study compares changes in those biomarkers between the two anesthetic exposures to see if one agent leads to less oxidant-related disruption. Participants meeting inclusion criteria and without the listed exclusions will be enrolled at a single center.

Who should consider this trial

Good fit: Adults aged 20–60 years with ASA physical status I–II who are scheduled for elective laparoscopic cholecystectomy and have no major chronic illnesses are the intended participants.

Not a fit: Patients with diabetes, chronic infection, major cardiac, hepatic, renal, endocrine, immune, mental or neurological disorders are excluded and the results may not apply to them.

Why it matters

Potential benefit: If one anesthetic produces less oxidative stress, clinicians could choose it to potentially reduce postoperative oxidative injury and inflammation.

How similar studies have performed: Previous comparisons of volatile anesthetics have shown mixed results, with some reports suggesting sevoflurane may be linked to lower oxidative stress but no clear consensus.
