Comparing I-Gel to Proseal Laryngeal Mask Airways in Infants: A Prospective Randomised Clinical Study.

Abstract

ObjectiveLaryngeal mask airways and the I-gel have become increasingly popular for children undergoing minor surgery. The goal of our study is to compare I-gel and ProSeal laryngeal mask airways (LMA) in infants by analysing different parameters, such as insertion success, ventilation, haemodynamic changes and postoperative complications.MethodsFor this prospective, randomised study, we selected 123 infants with an American Society of Anaesthesiologists (ASA) status I, who were undergoing minor elective lower abdominal surgery. After obtaining verbal and written informed consent from the parents, the infants were divided into two groups: the I-gel group (n=60) and the ProSeal LMA group (n=63). The times and ease of insertion, percentages of tidal volume leakage, and means and leakage pressures of these two supraglottic airways were noted. The complications and side-effects of each method were also recorded.ResultsThe insertion time of the ProSeal group was statistically shorter than that of the I-gel group. The peak and mean pressures and the leakage percentage of the ProSeal group were statistically lower than those of the I-gel group. The leakage pressure of the ProSeal group was statistically higher than the I-gel group.ConclusionIn comparison with I-gel, the use of ProSeal LMA in infants’ anaesthesia presents many advantages, such as the ease of its insertion, better oropharyngeal leakage pressure and less mucosal hyperaemia.
