A Comparative Study of Propofol and Thiopentone with local Anaesthetic Spray as Inducing Agents for I-Gel Insertion
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 1
Abstract
Aim: Of the study is to compare insertion conditions for I gel using propofol and thiopentone with lignocaine spray as inducing agents in terms of haemodynamic stability as well as in terms of no of insertion attempts, success of insertion, time taken for insertion, manipulations required, patient response to i- gel insertion, subjective ease of insertion and success of ventilation Material and Methods: 80 patients of age between 18-60 years with ASA grade I/II undergoing elective minor surgeries were divided into two groups. Group P (n=40) - received injection propofol 2.0mg/kg over 30 seconds. Group TL (n=40)- received 2 sprays of lignocaine 10% (10 mg/puff) to each side of oropharynx (total 40 mg) followed by injection thiopentone 5mg/kg over 30 seconds, ten minutes later. Result: Results showed that propofol caused decrease in mean heart rate in group (P), while tachycardia had developed as compared to baseline in thiopentone group (TL). A slight decrease in blood pressure for short duration was seen in both groups but significantly more in propofol group, so propofol caused more cardiovascular depression than thiopentone. Both the groups were comparable in terms of no of insertion attempts, success of insertion, time taken for insertion, manipulations required, patient response to i- gel insertion, subjective ease of insertion and success of ventilation. Conclusion: propofol gives ideal condition for I gel insertion with cardiovascular depression,while thiopentone with lignocaine spray provides the conditions for i-gel insertion equal to those of propofol, with more hemodynamic stability
