Comparative evaluation of I-gel vs. endotracheal intubation for adequacy of ventilation in pediatric patients undergoing laparoscopic surgeries

Kohli M, Wadhawan S, Bhadoria P, Ratan SK. J Anaesthesiol Clin Pharmacol. 2019 Jan-Mar;35(1):30-35

This study aimed to determine the efficacy of the i-gel as compared to the ETT in terms of adequacy of ventilation in 80 children (2-8 years of age) undergoing paediatric laparoscopic surgeries. Several parameters were evaluated including peak airway pressure, end-tidal CO2, minute ventilation, SpO2, as well as desufflation of the peritoneal cavity. These variables were recorded after securing the airway, after carboperitoneum (CP) and after desufflation of the peritoneal cavity. Results showed a significant increase in the partial pressure of mean expired CO2 (PeCo2), peak airway pressure, as well as minute ventilation in both groups after creation of CP. On the other hand, no difference was observed in heart rate or mean arterial pressure. Moreover, the i-gel showed a smaller increase in peak airway pressure and fewer post-operative complications. Thus, both devices were comparable in terms of adequacy of ventilation, but the i-gel was able to provide a safe alternative to the ETT.

I-gel versus laryngeal mask airway-Proseal: Comparison of two supraglottic airway devices in short surgical procedures

Jadhav PA, Dalvi NP, Tendolkar BA. J Anaesthesiol Clin Pharmacol. 2015 Apr-Jun;31(2):221-5

Ease and time to insertion, airway sealing pressure and adverse events were measured in this study of 60 patients randomly allocated to i-gel and ProSeal groups. i-gel proved easier to insert and less traumatic.

Nasopharyngeal airway as an aid to remove i-gel™ after endotracheal intubation through the device

Sen I, Bhardwaj N, Latha Y. J Anaesthesiol Clin Pharmacol. 2014 Oct;30(4):572-3

Use of NPA to aid removal of i-gel was evaluated in 20 adult patients - in 17 the device was inserted at the first attempt. No complications such as gagging and laryngospasm were noted during insertion or removal of i-gel.
