40 patients were split into equal gender groups prior to insertion. The EC50 of propofol in men was approximately 40% higher than in women. Gender should be considered when determining optimal dose of propofol, according to the authors.

This case report described the use of the i-gel for the management of ventilation in an ICU patient. A 49-year-old woman was hospitalized in ICU due to fever and respiratory distress. Three intubations using a bougie failed, but the airways were subsequently secured with an i-gel (size 3) at the first attempt. No issues were seen in mechanical ventilation using the i-gel for 48 hours in pressure-controlled ventilation. Thus, the i-gel can be used in difficult intubation scenarios, allowing mechanical ventilation up to 48 hours.

270 patients aged 0-12 years not requiring tracheal intubation were recruited. After induction, thenar eminence dimensions were measured and compared with the patient's inserted i-gel. Authors conclude their results showed that the dimensions of thenar eminence fitted the weight-based size selection of i-gel, and that it could be a practical way to choose the correct size device.

A cluster randomised trial of paramedics within one ambulance service in England over a 12-month period, split into groups using either the i-gel or LMA Supreme or usual practice for all patients with non-traumatic adult OHCA. Primary outcome was study feasibility, including recruitment and protocol adherence. Secondary outcomes included survival to hospital discharge and to 90 days. 184 of 535 paramedics consented, with 615 patients recruited. The LMA Supreme arm was suspended following 'adverse incidents'. No differences were reported in secondary outcomes.
