This study on 71 ASA I-II women scheduled for gynaecological surgery, reported a 97% insertion success rate with i-gel®. Mean seal pressure was 30cm H2O. A gastric tube was inserted in 100% of cases. Only one case of coughing and sore throat occurred. The authors concluded that ‘the i-gel® is a reliable, easily inserted airway device that provides an adequate seal with a low morbidity rate.’
