Effect of Local Anesthesia and General Anesthesia Using I-gel Laryngeal Mask Airway in Diabetic Patients Undergoing Cataract Surgery: Comparative Study

Amer GF, Abdeldayem OT, Lahloub FMF. Anesth Essays Res 2019 Apr-Jun; 13(2): 209-213

This investigation assessed the use of the i-gel as an alternative to local anaesthesia (LA) in insulin dependents diabetic patients undergoing cataract surgery. 60 diabetic patients were randomly assigned to receive either LA or general anaesthesia (n = 30) in combination with the i-gel (n = 30). Several parameters were monitored including mean arterial blood pressure (MBP), heart rate (HR), as well as blood glucose levels and plasma cortisol levels. Results have shown no significant difference in either blood glucose or cortisol levels in both groups. However, blood glucose level increased in both groups after induction of anaesthesia. In addition, HR and MBP increased in the LA group but not in the i-gel group. In conclusion, these results show that both LA and general anaesthesia using the i-gel are safe and do not produce a marked impact in hemodynamics, blood glucose, or cortisol levels in diabetic patients.

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.

I-gel™ May be the Device of Choice for Controlled Ventilation in Patients with Hemophilia Undergoing Abdominal Laparoscopic Surgery

Sen S, Mitra K, Ganguli S, Mukherji S. Anesth Essays Res. 2018 Jan-Mar;12(1):288-290

Peri-operative management of patients with haemophilia involves the risks of excessive bleeding. This is especially true when securing the patient’s airways during anaesthesia with standard instrumentation (e.g. direct laryngoscopy), as this could lead to severe haemorrhage. Therefore, this case study assessed the efficacy of the i-gel in the airway management of a patient with haemophilia undergoing laparoscopic cholecystectomy.

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.
