Jain D, Ghai B, Bala I, Gandhi K, Banerjee G. Paediatr Anaesth. 2015;25(12):1248-53

30 children induced with sevoflurane in oxygen and administered atracurium intravenously. Oropharyngeal leak pressure in neutral, maximum flexion and maximum extension were primary outcomes measured. In extreme flexion of head and neck, caution is warranted during ventilation.

Eighty children were split between each device group, with leak pressure and fibreoptic view assessed at three intervals. i-gel was 'significantly easier' to insert and had high pressures at all measurement points.

Forty children 2-5kg in body weight were allocated to either i-gel or LMA Classic groups, with oropharyngeal seal pressure the primary outcome measured. Results showed that i-gel OSP was higher and statistically significant.

A total of nine studies were included using search keywords, with results finding that i-gel gave significantly higher leak pressure and ProSeal. Authors conclude it is an effective alternative to ProSeal and cLMA.

Total of 170 children were assigned to either the i-gel® or LMA Supreme®, with leak pressure the primary outcome measured. Secondary evaluations included insertion time, insertion success rate, fibreoptic view and complications, to name a few. Resulting median leak pressure was higher with i-gel® and the authors conclude it could be a ‘useful alternative to the Supreme®’.
