Abstract
Background: The use of larger doses of neuromuscular blockers may shorten the onset of intubation. Aim of Study: This study aimed to evaluate the use of triple the (ED95) of rocuronium or cis-atracurium on the timing and the score of intubation in morbidly obese patients. Patients and Methods: Sixty adult morbid obese patients were included in this study and allocated randomly according to the muscle relaxant used for induction of anesthesia into either ROC group; in which 0.9mg/kg of rocuronium was used or CIS group; in which 0.15mg/kg of cis-atracurium was used. The onset and the duration of relaxation, the time of intubation, the intubation score, and the incidence of compli-cation were measured. In addition, the changes in the hemo-dynamic parameters were recorded. Results: In comparison to cis-atracurium, the use of triple (ED95) of rocuronium in rapid sequence induction of anesthesia significantly shortened the onset of relaxation from 96.00±13.29 to 84.00±18.50sec (p=0.005, CI 3.675; 20.325), and the time of intubation from 104.55±17.91 to 89.14±20.43 sec (p=0.002, CI 6.00; 24.82). However, the duration of relaxation was significantly prolonged from 58.76±9.27 to 69.86±8.38min (p=0.003, CI 2.533; 11.667). Moreover, the intubation score was comparable between the two groups (p=0.994). Conclusion: The use of triple the (ED95) of rocuronium as compared to cis-atracurium in rapid sequence induction of anesthesia of morbidly obese patients significantly shortened the onset of relaxation and the time of inubation with an insignificant effect on the intubation score.
