This review article compares supraglottic airways to tracheal intubation for laparoscopic surgery. Evidence gathered so far indicates that supraglottic airways such as the i-gel® produce adequate ventilation and pressures with a reduced risk of complications such as aspiration. The authors state that further investigation should take place to determine whether these devices can be used in obese patients during laparoscopic procedures.
