Tracheal Intubation without Muscle Relaxant Comparison Between Three Techniques

Abstract

The standard techniques of tracheal intubation are usually done after induction of anaesthesia followed by skeletal muscle relaxation. The muscle relaxants are associated with many side effects. These side effects have spurred research into development of alternative methods for providing good intubation condition.

Forty-five patients with ASA grade I or II, having Mallampati class-I or II airways were divided in three groups depending on administration of drugs in a double blind randomized study. Group-A, thiopental sodium (5mg/kg) + fentanyl (10mcg/ kg) + lignocaine(1mg/kg), Group-B, thiopental sodium (5mg/kg) + fentanyl (10mcg/kg ) and Group-C, thiopental sodium (5mg/kg) + suxamethonium(1mg/kg) Group-C acted as control. The blood pressure and heart rate were measured before induction,after induction and after intubation. Ease of intubation was judged by Scheller intubation criteria. The intubation was possible in all patients of the three groups and there were no significant differences between them in respect to total score.
