Abstract

Objective: Inj thiopental is known to result in hypotension during induction, and the effect is more pronounced in hypertensive patients. This study aimed to compare the effect of two different anesthesia induction regimens with pentothal in managing the hemodynamic response to laryngoscopy and endotracheal intubation in known hypertensive patients.
Methodology: The study was conducted in Van Educational Research Hospital in 2014 after approval from the ethics committee and informed consent from patients were obtained. The prospective, double-blind, randomized study included the American Society of Anesthesiologists (ASA) grade II–III 90 patients, aged 40–65 y, scheduled for elective abdominal surgery with general anesthesia. Thiopental (3–7 mg/kg) was given to the patients in Group 1 (n = 45) with single dose injection in 20 s. In Group 2 (n = 45), first 75% of the thiopental dose was given, and after the bispectral index–based scale (BIS) value was < 60 and after injecting neuromuscular blocking agent, the rest of the thiopental dose was added and injection duration was recorded. In both groups, midazolam 0.05–0.1 mg/kg was administered for premedication. Fentanyl and rocuronium were used in both groups to complete induction. During the first 25 min, systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, and heart rate of the patients were recorded. Also, BIS values after induction and total additional fentanyl requirement were recorded.
Results: Heart rate, mean arterial pressure, and additional fentanyl requirement was significantly lower in Group 2. BIS values were also lower in Group 2. Induction duration was higher in Group 2, but hemodynamic control was more satisfying.
