Abstract :

Background and aims:To avoid the complications associated with endotracheal intubation ⁽¹⁾the efficacy of newer supraglottic devices⁽²⁾ are being tested in term of ventilating patient.This randomised study was conducted with aim of compå I–gel and Laryngeal tube in terms of ease of insertion,ventilatory parameters like Leak pressures,Peak pressures,Dynamic airway compliance.

Materials and methods: a total of 60 patients ,scheduled for gynaecological laparoscopic surgeries were randomly allocated to group I (n=30)to be ventilated with i–gel and group L (n=30)to be ventilated with laryngeal tube. Ease of insertion,Ventilatory parameters like Leak pressures,Peak pressures,Dynamic airway compliance were noted. Sample size was calculated at 90% study power and alpha error 0.05, assuming standard deviation of 13ml/cm for all devices for the minimal detectable difference of 12ml/cm in dynamic airway compliance.Statistical analysis was done using Microsoft excel software using the students t–test and chi–square test (level of significance p=0.05).

Results : Ease of insertion in terms of number of attempts and time taken for insertion was better with I–gel. Leak pressures were higher for I–gel and Dynamic airway compliance were comparable in both groups..

Conclusion:I–gel is a better alternative to endotracheal intubation in compared to Laryngeal tube in electively ventilating gynaecological laparoscopic surgeries..
