Clinical trial for comparison of clinical performance of I-Gel with LMA-proseal in elective surgeries

Abstract

The I-gel is genuinely interesting second era supraglottic aviation route gadget with delicate gel like non inflatable sleeve. The objective of this study was to evaluate and compare the ease of insertion and number of insertion attempts, airway sealing pressure, and fibrotic evaluation of device position and occurrence of complication. A Total 70 adult patients were allocated to either i-gel group or P-LMA group with 35 patients in each group. Both i-gel and P- LMA were introduced with standard technique. The outcomes measured were ease of insertion, number of insertion attempts, airway sealing pressure, haemodynamic changes, fibrotic evaluation of device position and complications. For the i-gel group the success rate at ease of insertion was greater (97% vs 72% respectively; P=0.012). Airway sealing pressure was lesser (24.72±1.37 cm H2O vs 30.09±2.64 cm H2O respectively; P=0.0003). The incidence of postoperative sore throat was lower (2.8% vs 25.7% respectively; P=0.01). Changes in haemodynamic parameters were not clinically significant. The i-gel is easier to insert than P-LMA however with a lower airway sealing pressure. It has a lower incidence of postoperative complications.
