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.

i-gel as an intubation conduit: Comparison of three different types of endotracheal tubes

This investigation aimed to compare the successful intubation rate of the i-gel using three types of endotracheal tubes (ETTs). 75 ASA I and II patients (age 18-60 years) undergoing elective surgery under general anaesthesia were randomly assigned into three groups based on the type of endotracheal ETT, which included polyvinyl chloride ETT (Group P), intubating laryngeal mask airway ETT (Group I) and flexometallic ETT (Group F). Recorded parameters included time taken for successful intubation, success rate, number of attemps, manoeuvres, and complications. Results demonstrated that Group P had the lowest time and mean time for intubation, as well as the highest first attempt and overall intubation success rate. Therefore, the combination of polyvinyl chloride ETT with i-gel to intubate patients with difficult airways represents the most successful approach compared to other combinations. However, additional studies are needed to validate these results.
