In this study, the i-gel®’s placement and performance were studied for insertions carried out with and without the use of a gum elastic bougie. 50 patients were randomised into two groups. In the first group, the i-gel® was inserted using the standard method. In the second group, a bougie was used to insert the device via the gastric channel. The time taken for insertion and the number of attempts needed were similar for both methods. Leakage and patient discomfort were less common when the bougie was used. The authors conclude that using a bougie improves i-gel® placement without increasing insertion time or adverse effects.
