i-gel® from Intersurgical: clinical evidence listing

Mitra S, Das B, Jamil SN. North American Journal Of Medical Sciences 2012; 4(10): 453-7

Investigation on the usefulness of paediatric i-gel® size 2.5 against the PLMA equivalent in 60 randomly assigned patients due for anaesthetised elective surgery. Leak pressure was the primary outcome recorded, with further results for ease of insertion, hemodynamic data and postoperative complications also measured. Most areas offered no significant difference, although i-gel® proved easier to insert and recorded a higher leak pressure. Due to author-defined parameters such as cost-effectiveness, they deduce that i-gel® ‘must be more frequently used’.

Three groups of 40 elective patients each were assigned to i-gel®, LMA Supreme® and Laryngeal Tube Suction-D for a prospective, randomised and comparative study of position (fibre optic) and clinical performance data during surgery. Speed of insertion and success rates, leak pressure, dynamic airway compliance, and signs of postoperative airway morbidity were recorded, with i-gel® registering a 95% insertion success rate and the highest airway compliance. In conclusion, all devices were considered suitable for ventilation in elective surgery.

An experimental study using i-gel® on 100 female patients undergoing elective gynaecologic surgery was performance-measured on ease of insertion, time to insert, peak airway pressure and leak pressure. A gastric tube was placed in each patient. Pharyngolaryngeal morbidities were also recorded. In 92% of patients, i-gel® was inserted successfully first time and there were no instances of blood on the device post-procedure. Authors confirm the i-gel® is a simple and easy to use device.

Following a short lecture and manikin training, novice airway users were randomly selected to insert either the LMA Supreme® or i-gel® into 80 patients undergoing breast surgery, to measure insertion success rate and ventilation profile.

A prospective, randomised and controlled test of 134 children, aged three months to 15 years old, undergoing general anaesthesia were inserted with either i-gel® size 1.5-3 or ProSealTM equivalent to gauge insertion performance. Outcome variables included leak pressure, ease of insertion, success rate and fibreoptic view. Most outcomes were very similar, however fibreoptic view was significantly better with i-gel®.
