100 participants were presented with a manikin and an airway management package containing a labelled i-gel and a mouthpiece with a filter which connected to the i-gel connector. They were given a sheet of instruction and attempted to ventilate the manikin. Time to ventilation, success rate, i-gel position and direction, and participant age and first aid experience were recorded. Participants rated their success and the ease of use, stated whether they would use the device in an emergency, and stated whether they would feel comfortable performing ventilation with the device. The three devices were generally comparable. However, the i-gel was quicker to insert, most likely due to the lack of inflatable cuff. The incidence and severity of both perioperative and postoperative complications was low.

100 participants were analysed using a labelled i-gel with an integrated mouthpiece and asked to follow an instruction chart. 79% were able to ventilate the manikin effectively, with 90% using the correct turn and direction.

Patients were assigned to a warm (at 42 degrees centigrade) or control room temperature group. Number of attempts until successful insertion and sealing pressure were compared. Authors conclude that pre-warming did not increase insertion success rate.

Collating data from 12 observational studies on the topic, covering both guidelines, the aim was to investigate the effect of both methods of treatment on cardiac arrest patients. Authors concluded that there is an ‘association with improved survival’ when cardiocerebral (CCR) protocols or 2005 Guidelines are compared with older versions, and that CCR appears to be a ‘promising resuscitation protocol for Emergency Medical Services’.
