ABSTRACT

Both the Supreme Laryngeal Mask Airway (SLMA) and the I-gel (I-gel) are supraglottic airway devices (SADs) commonly used for airway management in paediatric patients. This study aims to compare the efficacy in terms of insertion and ventilation profiles of size 2 SLMA and the I-gel in anaesthetised paediatric patients.

100 children were prospectively allocated to two groups depending upon the device inserted as SLMA (n = 50) and I-gel (n = 50). The primary outcomes were studied in terms of ease of insertion, haemodynamic changes, ventilation parameters, leak pressure and incidences of complications during general anaesthesia.

There were no failed attempts in the insertion of the airways in either group. The SLMA was more easily inserted in the majority of cases compared to the I-gel group. The number of attempts for insertion and the time taken for insertion were comparable in the I-gel and the SLMA group (13.8462.38 vs. 14.0261.7) (P .57, .66). Securing an effective airway took <30 seconds in both the groups with an overall median duration of 15 seconds. There was no difficulty in passing the gastric tube in either group (P<.30). There was a statistical difference between the oropharyngeal seal pressure (OSP), which was 25.1861.59 and 22.1061.36 cmH2O for SLMA and I-gel, respectively (P<.001). Haemodynamic parameters after the insertion of the device were comparable, and there were no clinically important complications in the post-operative period.

Both the devices appeared to be simple and suitable for airway management during elective surgery in paediatric patients. However, the SLMA was easily inserted with less insertion time in the majority of patients. Also, it provides higher OSP during anaesthesia and is better tolerated during emergence, with minimal risk of injury to the oropharynx.
