RESUMEN
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 and Duration of study: Department of Anaesthesiology and 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
