Comparison of I-gel versus Endotracheal Tube in Patients Undergoing Elective Cesarean Section: A Prospective Randomized Control Study

Panneer M, Babu S, Murugaiyan P. Anesth Essays Res. 2017 Oct-Dec; 11(4): 930–933 
 
The objective of this study was to compare the hemodynamic disturbances and possible complications caused by the i-gel and ETT in 80 patients (ASA II) undergoing cesarean receiving general anesthesia. A range of parameters was investigated including insertion time, ease of intubation, hemodynamics (insertion and removal) and postoperative complications (sore throat, blood on device, dysphagia, regurgitation, nausea, vomiting, laryngospasm and aspiration). Findings have demonstrated that patients in the ETT group had a higher incidence of difficult intubation, 20% higher mean arterial pressure and heart rate compared to the i-gel group. The ETT group also had a higher incidence of sore throat. Thus, the i-gel constitutes a superior alternative to the ETT in patients undergoing elective surgery under general anaesthesia.

Assessment of suitability of i-gel and laryngeal mask airway-supreme for controlled ventilation in anesthetized paralyzed patients: A prospective randomized trial

Radhika KS, Sripriya R, Ravishankar M, Hemanth Kumar VR, Jaya V, Parthasarathy S. Anesth Essays Res. 2016;10(1):88-93

Patients were split into i-gel and LMA Supreme groups, with insertion attempts, time and any manoeuvres needed forming outcomes, along with peak inspiratory pressure (PIP).  LMA-S was inserted successfully in more patients, but with no significant difference in PIP.

Effect of pneumoperitoneum and Trendelenberg position on oropharyngeal sealing pressure of I-gel™ and ProSeal LMA™ in laparoscopic gynecological surgery: A randomized controlled trial

Mishra SK, Sivaraman B, Balachander H, Naggapa M, Parida S, Bhat RR, Yuvaraj K. Anesth Essays Res. 2015 Sep-Dec;9(3):353-8

60 patients were enrolled to either i-gel or ProSeal groups, with the primary objective to compare sealing pressure. Authors conclude ProSeal gave a better seal.

Is I-gel airway a better option to endotracheal tube airway for sevoflurane-fentanyl anesthesia during cardiac surgery?

Elgebaly AS, Eldabaa AA. Anesth Essays Res. 2014 May-Aug;8(2):216-22

49 adult patients were randomly assigned between each device group, with fentanyl doses, hemodynamic parameters and mean arterial pressure among results taken at various points throughout the procedure. i-gel requires less anaesthetic doses in this scenario.
