Comparison of Ease of I-Gel Insertion with Standard and Rotational Techniques in Adults.
J Surg Pak Jan ;21(4):122-5.

Objective: To compare number of attempts, mean time of Insertion, mean airway leak pressure, insertion success and blood staining at removal of l-gel insertion through standard and rotational techniques, in adult anesthetized patients. Study design: Randomized clinical trial. Place & Duration of study: Department of Anaesthesiology& SICU, Jinnah Postgraduate Medical Centre Karachi, from January 2016 to April 2016. Methodology: Patients scheduled for elective surgical procedures under general anaesthesia with controlled ventilation, were included in this study. A total of 150 patients were randomly assigned by random number into Group S (standard insertion technique - n=75) and Group R (rotational technique - n=75). Comparison was done in terms of mean time taken for I-gel insertion, mean air leak pressure, number of attempts taken for insertion and presence of blood staining on removal. Results: Mean time of insertion in Group S was 14.6 ± 3.7 second and in Group R 13.2 ± 2.7 seconds. Mean airway leak pressure was 23.1 ± 4.6 cm of H2O in Group S and 24.4 ± 2.9 cm of H2O in Group R. The median number of attempts taken for insertion in each group was 1. Success of insertion was 93.3% (n=70) in Group S and 98.7% (n=74) in Group R. Blood staining of I-gel at removal was noted in 22 (29.3%) and 14 (18%) patients in group S and R respectively. Conclusion: The rotational technique for I-gel insertion was better than the standard technique.
