BackgroundAt 60 seconds, 2xED95 dose (0.6mg/kg) of rocuronium is frequently used for intubation. Some studies suggest 3XED95 (0.9mg/kg body weight) dose in achieving excellent intubating conditions. In this context, present study aimed at comparing intubating conditions with these two doses of rocuronium, using clinical criteria by cooper's score; assisted with adductor pollicis T.O.F response.Materials And MethodsPresent prospective randomized comparative clinical study was conducted on 60 patients subjected for general anaesthesia. Induction was done with fentanyl (1mcg/kg body weight) and propofol (2mg/kg body weight) and relaxation achieved with Rocuronium 0.6 mg/kg (Group A-30 cases); 0.9mg/kg (Group B- 30 cases). (n=30) intubation was done at 60 seconds. Intubating conditions were assessed clinically by cooper's score.T.O.F responses of AP by visual and tactile means.ResultsIntubating conditions clinically were excellent in 16 cases (53%), good in 12 cases (40%), and fair in 2 cases (7%) respectively in Group-A. In group-B excellent in 29 cases (97%) and good in 1case (3%). In group A in no case TOF-0 achieved. TOF 1, 2, 3, and 4 were observed in 1 case (3%), 7 cases (23%) 16 cases (54%) and 6 cases (20%) respectively. Whereas in group B, TOF 0, 1, 2, 3 were observed in 18 cases (61%), 4 cases (13%), 7 cases (23%) and 1 case (3%). In no case TOF-4 observed. Chi square test (p<0.0001) confirmed a highly significant statistical difference with respect to elicited TOFcounts, and intubating conditions achieved.Conclusion3xED95 dose of Rocuronium achieves more intense NMB and better conditions for intubation at 60 seconds than 2ED 95 dose.
