A proposal for a new scoring system to predict difficult ventilation through a supraglottic airway

Saito T, Chew ST, Liu WL, Thinn KK, Asai T, Ti LK. Br J Anaesth. 2016 Sep; 117 Suppl 1: i83-i86

By using previously reported derivation data, a score was validated in 5532 patients ranging between 0 and 7 points. Under this format, the authors conclude the scoring system to be easy to perform and reliable.

Supraglottic Airway Devices and Effect on Voice-Comparison of LMA Proseal and i-gel: Double-Blind Randomized Clinical Trial

Vaidya S, Kundra P, Gopalakrishnan S, Parida P, Yuvaraj K, Mohan PM. J Voice. 2016 Sep;30(5):631-7

90 adult patients were randomly assigned to LMA Proseal and i-gel groups, with voice evaluated using perceptive and acousitc analysis. In both groups voice results deteriorated comparably.

A comparison of QTc intervals after laryngoscopic intubation and i-gel insertion during propofol-sevoflurane anaesthesia

Byon HJ, Song J, Shinn HK, Song K, Lee C, Lim H. Minerva Anestesiol. 2016 Sep;82(9):950-6

Patients were randomly assigned to either the i-gel or intubation group and induced using propofol or sevoflurane. Peak QTc interval was lowever in the i-gel group. Authors conclude the i-gel 'may be advantageous' to patients at risk of QTc prolongation.
