Abstract
Background & Objectives: Intubating laryngeal mask airway (ILMA) is a supraglottic airway device (SAD) frequently used as conduit for endotracheal intubation when intubation under direct laryngoscopy is undesirable. A newer SAD i-gel is popular now because of its ease of insertion and performance. It can be used as a conduit for endotracheal intubation also. This study compared the success rate of blind endotracheal intubation through ILMA and i-gel
Methods: A total of 86 patients undergoing elective surgery under general anaesthesia were divided in two groups of 43 patients each to receive intubation through the ILMA (Group L) or i-gel (Group G). Anaesthesia was induced and selected SAD was inserted. After confirming adequate ventilation with the SAD, blind endotracheal intubation was attempted through the SAD. Success of intubation was noted and time taken for tracheal intubation was measured. IBM SPSS Statistics 20.0 software was used to analyse the data. P < 0.05 was considered as statistically significant.
Conclusion: ILMA is superior to i-gel as a conduit for blind endotracheal intubation because of its overall higher success rate. However, the statistically similar success rate in first attempt of tracheal intubation and the significantly lesser time required for insertion of i-gel make it a reasonable alternative to ILMA for intubation and an excellent choice for rescue ventilation.
