Comparison of Sevoflurane and Propofol for Insertion of I-Gel in Patients Undergoing Minor Elective Surgical Procedures under General Anaesthesia

ABSTRACT

A popular method of providing anaesthesia for I-Gel insertion is with the use of propofol. However, boluspropofol has been associated with adverse effects such as hypotension, apnea and pain on injection. Hence,time is needed to search an alternative. We aimed to compare the induction characteristics, ease of I-Gelinsertion, hemodynamic changes and complications with inhalation of 8% sevoflurane vital capacity breathand propofol. A prospective randomized study of 60 American Society of Anaesthesiologists’ Grade I and IIpatients was conducted and distributed among two groups with 30 each undergoing minor surgical proceduresunder general anaesthesia. Group P received the injection propofol and Group S received sevoflurane. At theend point of induction, the I-Gel insertion was attempted. Scoring systems were used to grade the conditionsfor insertion of the I-Gel. Induction, I-Gel insertion characteristics and hemodynamic changes were assessed.Data were recorded and analysed. Comparison among the study groups was done with unpaired t-test,Mann–Whitney test and Chi square test. Sevoflurane took a longer time for induction and for I-Gel insertionthan propofol. There was no statistically significant difference between the two groups, with respect to I-Gelinsertion characteristics, heart rate, and mean arterial pressure. It is concluded that sevoflurane is associatedwith good hemodynamic stability and may prove useful in cases where propofol is to be avoided. However,the ease of insertion provided with propofol is better.
