A Comparative Evaluation of Respiratory Parameters Spo2 and Etco2 with Paediatric I-Gel, Proseal LMA Vs Endotracheal Tube

Abstract

Introduction: Supra Glottic Airway devices have set a new trend in airway maintenance since their invention. Availability of these devices in the paediatric sizes has revolutionized their use. Endo Tracheal Tubes have always been considered “Gold Standard” owing to their ability of maintaining stable respiratory parameters and in prevention of aspiration. We have compared the repiratory parameters achieved with Paediatric I-Gel, Proseal -LMA and Endo Tracheal Tube. Description: 120 children aged 2 to 12 years, both sex, ASA 1 and 2, posted for elective surgery were included in the study. They were divided into 3 groups of 40 each - Endo Tracheal Tube (E), Proseal LMA (P-LMA) and I-GEL respectively. The device was inserted after induction of anaesthesia and the respiratory parameters namely SpO2 and EtCO2 were recorded at various time intervals. Result: All values were analysed and expressed as mean +/– SD. Statistical comparison was done by unpaired student “t”- test and chi square test. The values obtained for various time intervals were found to be statistically insignificant for all the three devices. Conclusion: PaediatricProseal LMA (P-LMA) and I-GEL are very much comparable with Endo Tracheal Tube (E) with regard to respiratory parameters and hence can be safely used as an alternative airway in the paediatric population.
