Insertion Time of the 1-Gel and LMA-C in Adult Patients under Anesthesia: A Comparison

Abstract

Objective: To evaluate the time required for the insertion of I-gel and LMA-C in adult patients under general anesthesia.

Study Design: Randomized Control Trial

Place and Duration of Study: This study was conducted at the Anesthesia department DHQ Teaching hospital Sahiwal, from December 2016 to May 2017.

Materials and Methods: A total of 166 Patients of either sex, meeting the inclusion criteria enrolled from outpatient department. All the patients were randomly divided into two equal groups, group A and group B with 83 patients in each group. In group A. patients laryngeal mask airway was administered and inflatable cuff was inflated to 60 cm H₂O. Similarly in group B. I-gel was administered.Mean and standard deviation was calculated for qualitative variables while frequency and percentage was calculated for quantitative variables. Chi square test was applied and P value less than and equal to 0.05 was considered as significant.

Results: Gender distribution was as follows; 56.6% males in group A and 55.4% males in group B while 43.4% females in group A and 44.6% females in group B. Mean and standard deviation of age in group A and B was 38.58+1.01 and 38.71+1.13 respectively. Mean insertion time was 30.76+0.71 in group B and 34.16+0.74 in
group A.

Conclusion: I-gel has significantly shorter average insertion time as compared to LMA Classic.
