Abstract:
Objective: To assess symptoms of nausea and vomiting in laparoscopic cholecystectomy post-operatively, administered
anesthesia by sevoflurane or propofol and to assess the effect of dexamethasone and ondansetron anti-emetic combination.
Study design & Setting: It was an experimental study design conducted from 08-Oct-2017 till 11-Jul-2018 at Rawal
General & Dental Hospital.
Methodology: Patients were recruited in interventional groups by lottery method as n=160, with 80 cases allocated in each
group. The patients with gallstones planned for laparoscopic cholecystectomy after preoperative assessment were classified
to American Society of Anesthesiologist (ASA) physical status class I-II. All the patients placed in a particular ASA physical
status class were (exposed to both induction methods) either anesthetic induction by propofol 1-2 mg/kg (group-A) or by
employing sevoflurane 4-8% (group-B) in combination with oxygen, while maintenance was done in both study groups
with 2% sevoflurane and 50% nitrous oxide in oxygen. After procedure patients stayed in post-anesthesia care unit where
intra-operative monitoring was evaluated. The primary end point of the study was to note the rate of nausea and vomiting
in 24 hours interval after surgery.
Results: Both sevoflurane and propofol are equally effective anesthetic induction agents. The same combination of
dexamethasone and ondansetron was given to both groups and so the actual effect of both anesthesia drugs in terms of side
effects were nullified.
Conclusion: In laparoscopic cholecystectomy, both sevoflurane and propofol are good enough when administered with
dexamethasone and ondansetron anti-emetic combination, for post-operative nausea and vomiting up to 24 hours observation
time in study.
