Baxter, S. Anaesthesia 2008; 63(11): 1265
This correspondence article reports a problem that occurred in two patients ventilated with an i-gel® during anaesthesia. In the first case, anaesthesia started to lighten and end-tidal sevoflurane fell. The user suspected air entrainment through the suction port. In the second case, anaesthesia remained stable but end-tidal sevoflurane still dropped. The user placed a finger over the suction port and sevoflurane levels returned to normal. In both cases, the i-gel® was replaced with a laryngeal mask airway.
