The aim of this study was to compare two different airway devices; the laryngeal mask airway and the I-Gel regarding easiness of insertion, gastric insufflation ,end tidal Co2, oxygen saturation & postoperative complications in anesthetized spontaneously ventilated adult patients performing different non-emergency surgical procedures. 80 patients were enrolled in the study and were randomly allocated to one of treatment groups: I-gel group and LMA group. Patients were assessed for hemodynamic stability (HR, and arterial blood pressure), SPO2, end tidal CO2, easiness of insertion, leak pressure, gastric insufflation and post operative complications. Both studied groups were matched as regarding age, sex and BMI (p-value > 0.05).
As regarding the hemodynamic stability and effect of each of the supraglottic devices, no statistically significant difference was reported when comparing heart rate, systolic and diastolic arterial blood pressure throughout the surgery.
The differences between both groups of the study as regarding SPO2, end and tidal CO2 were not statistically significant at any time during operation.
The insertion and ventilation was possible at the first attempt in 90% of patients in the I-gel group and in 80% in ILMA group. In5% of the studied patients in LMA group, intubation and ventilation was possible after the third attempt. The mean duration of insertion attempts was 15.62 seconds in I-gel group while it was 26.2 seconds in LMA group. The difference between both groups regarding number and duration of insertion attempts was statistically significant (p-value < 0.05).
The difference between LMA and I-gel regarding post operative complications were not statistically significant.
It was estimated that leak pressure was significantly higher among studied patients of the I-gel group (25.62 versus 21.2 in LMA group; p-value < 0.05). Gastric tube was successfully inserted in 95% of patients of I-gel group.
The incidence of gastric insufflation was significantly more with LMA (22.5% versus 5% in I-gel group).
from the previous results we can conclude that both LMA and I-gel don’t cause any significant alteration in the hemodynamic status of the patients, end tidal CO2, and SPO2. The post operative complications are not significantly different among both LMA and I-gel. Insertion of I-gel is significantly easier and more rapid than insertion of LMA. Leak pressure is significantly higher with I-gel than LMA and thus incidence of gastric insufflation is significantly lower with I-gel.
