Comparison of LMA Classic and i-gel in anesthetized, spontaneously breathing patients during elective surgical procedures

Objective: The primary objective of this study was to compare two supraglottic airway devices regarding mean insertion time. Secondary objective was to assess the devices regarding first attempt success and ease of insertion. Tertiary objectives were to compare the post removal cough, laryngospasm and blood on device. Methodology: Interventional quasi experimental study conducted in Department of Anesthesiology, ICU & Pain Management Sheikh Zayed Hospital, Rahim Yar Khan from April 2012 to October 2012. 100 adult patients aged 15 to 70 years, ASA-I and II, Mallampati I and II, who were scheduled for various elective surgical procedures under general anesthesia were taken. Study was conducted in anesthetized spontaneously breathing patients. The patients were divided into i-gel and LMA groups by draw method. SPSS 16 was applied for analysis. Results: No statistically significant difference was reported between the groups, regarding mean insertion time, first attempt success, ease of insertion, cough and laryngospasm. Blood on LMA after removal had significantly greater incidence than on i-gel (10% on LMA group while none in i-gel group). Conclusion: Both i-gel and LMA Classic can be used safely and effectively in selected patients under general anesthesia with spontaneous breathing
