【 摘 要 】

Objectives: To compare efficacy in term of intubating condition between rocuronium and succinylcholine for rapid sequence induction in cesarean sectionMethodology: This randomized controlled trial was conducted at anesthesia department of our hospital at Nawabshah from January to December 2016. A total of 124 full term patients with Mallampati I & II and American Society of Anesthesiologists (ASA) physical status class I and II were randomly allocated into two groups. Group A (62 patients), was treated with succinylcholine chloride and Group B (62 patients) received rocuronium bromide for intubation. Intubating conditions were assessed by jaw relaxation, movement of vocal cords and bucking. Efficacy was labeled as ‘Yes’ when score 8 and 9 (excellent) otherwise ‘No’ if score was less than 8 “good and poor”. Blood pressure, heart rate, and SpO2 were monitored.Results: - The average age of the patients was 32.37 ± 1.98 y. Overall rate of excellent intubating conditions at one min was observed in 103 (83.1%) patients, good in 17 (13.7%) and poor in 4 (3.2%).  The frequency of clinically acceptable intubating conditions (i.e. excellent) was 87.1% in group A and 79.03% in group B which is not statistically significant.Conclusion: Rocuronium can be safely used for rapid sequence induction in caesarean sections and the intubating conditions are similar to those of succinylcholine.
