Postoperative sore throat: a systematic review

El-Boghdadly K, Bailer R, Wiles M. Anaesthesia 2016;71(6):706-17

Review into prevalence of sore throat after use of supraglottic airway devices against tracheal intubation in general anaesthesia. Authors suggest that, in adults, i-gel results in a lower incidence of post-operative sore throat.

Male patients require higher optimal effect-site concentrations of propofol during i-gel insertion with dexmedetomidine 0.5 μg/kg

Choi JJ, Kim JY, Lee D, Chang YJ, Cho NR, Kwak HJ. BMC Anesthesiol. 2016 Mar 22;16:20

40 patients were split into equal gender groups prior to insertion. The EC50 of propofol in men was approximately 40% higher than in women. Gender should be considered when determining optimal dose of propofol, according to the authors.

Pressure support ventilation with the I-gel in intensive care unit: case report

Akan B, Erdem D, Albayrak MD, Aksoy E, Akdur F, Gogus N. Braz J Anesthesiol. 2016;66(2):219-21

This case report described the use of the i-gel for the management of ventilation in an ICU patient. A 49-year-old woman was hospitalized in ICU due to fever and respiratory distress. Three intubations using a bougie failed, but the airways were subsequently secured with an i-gel (size 3) at the first attempt. No issues were seen in mechanical ventilation using the i-gel for 48 hours in pressure-controlled ventilation. Thus, the i-gel can be used in difficult intubation scenarios, allowing mechanical ventilation up to 48 hours.
