Abstract
A randomized controlled trial was conducted at the Main Operation Theatre of Jinnah Postgraduate Medical Centre (JPMC) in Karachi to compare the recovery profile and hemodynamic effects of cisatracurium and atracurium among patients undergoing laparoscopic cholecystectomy. The study was conducted from 20th July 2019 to 19th January 2020 and included 68 patients aged between 20 to 50 years undergoing elective laparoscopic cholecystectomy under general anesthesia. Patients with a history of allergy to the study drugs, neuromuscular, pulmonary, renal, or hepatic diseases, smoking, pregnancy, or breastfeeding, and those on preoperative medication such as antipsychotics, aminoglycosides, steroids, or neuroleptics were excluded. The patients were randomly divided into two groups. In Group 1, comprising 34 patients, cisatracurium (0.2 mg/kg) was administered, whereas in Group 2, also with 34 patients, atracurium (0.5 mg/kg) was given. Neuromuscular blocking agents were administered three minutes before intubation. The primary outcomes measured were the recovery profile and hemodynamic effects. In Group 1 (cisatracurium), the baseline mean arterial pressure (MAP) was recorded as 98.40 ± 8.02 mmHg, which increased to 112.20 ± 8.88 mmHg before intubation, resulting in a change of 13.56 ± 5.59 mmHg. In contrast, in Group 2 (atracurium), the baseline MAP was 94.10 ± 7.91 mmHg, which rose to 109.07 ± 8.35 mmHg before intubation, indicating a change of 16.50 ± 4.38 mmHg. The study concluded that cisatracurium is more effective in exhibiting neuromuscular blocking properties than atracurium in patients undergoing laparoscopic cholecystectomy under general anesthesia.
