COMPARATIVE STUDY OF SUPRAGLOTTIC AIRWAY DEVICES CLASSIC LMA, PROSEAL LMA AND I-GEL IN ADULT PATIENTS

BACKGROUND: The LMA has been used more than 150 million times word wide without a single death directly attributed to its use compare the supraglottic airway devices I-GEL, Proseal LMA and Classic LMA. AIMS : This study to evaluate the hemodynamic changes, time of insertion, ease of insertion , attempts of insertion, , gastric tube passage & post op complications. METHODS: 90 patients were randomized into three groups. (each group 30 patients) .Group C- Cassic LMA, Group  P- Proseal LMA, Group  I– I-GEL RESULTS :The airway leak pressure of the Proseal LMA group (22.06 ± 1.17 cmH2O) was significantly higher than that of the I GEL group (21.9 ± 2.17 cmH2O) and the  C LMA group (20.13 ± 1.24cmH2O). The success rates for first attempt of insertion were similar among the three devices. There were no differences in the incidence of postoperative airway trauma, sore throat or hoarse cry in all the three groups CONCLUSION: Both I-GEL, P LMA have an added advantage of gastric channel comparing these 2 devices easy passage of gastric tube through P LMA was easier than I GEL group.
