Impact of Isoflurane and Sevoflurane on Oxidative Stress in Patients Undergoing Laparoscopic Cholecystectomy

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

The primary aim of this work is to assess the impact of exposure to isoflurane or sevoflurane as an inhalation anesthetic on the oxidative stress and inflammatory conditions in patients undergoing elective moderate invasive surgery (laparoscopic cholecystectomy).

Oxidative stress is defined as "an imbalance between oxidants and antioxidants in favour of the oxidants, leading to a disruption of redox signalling and control and/or molecular damage.

Isoflurane, which has been utilized since the 1980s, has a particularly low metabolism rate and solubility, leading to reduced induction of anesthesia during surgery and shortened recovery time after surgery.

Sevoflurane began to be used a decade later and has a lower blood-gas partition coefficient than the other anesthetics, leading to rapid induction of anesthesia and fast awakening after anesthesia.
