This study aimed to determine the efficacy of the i-gel as compared to the ETT in terms of adequacy of ventilation in 80 children (2-8 years of age) undergoing paediatric laparoscopic surgeries. Several parameters were evaluated including peak airway pressure, end-tidal CO2, minute ventilation, SpO2, as well as desufflation of the peritoneal cavity. These variables were recorded after securing the airway, after carboperitoneum (CP) and after desufflation of the peritoneal cavity. Results showed a significant increase in the partial pressure of mean expired CO2 (PeCo2), peak airway pressure, as well as minute ventilation in both groups after creation of CP. On the other hand, no difference was observed in heart rate or mean arterial pressure. Moreover, the i-gel showed a smaller increase in peak airway pressure and fewer post-operative complications. Thus, both devices were comparable in terms of adequacy of ventilation, but the i-gel was able to provide a safe alternative to the ETT.
