Aims and Objectives: To study the effect of pneumoperitoneum on hemodynamic and respiratory parameters using Proseal LMA and endotracheal intubation and compare risk and benefits of using these two devices for video-endoscopic surgeries in children. 

Method: Total 60 ASA grade I children of either sex in the age group of 1-10 years were assigned randomly into two groups of 30 patients in each. Group I - Consists of patients airway secured with Proseal LMA and Group II - Consists of patients airway secured with endotracheal tube. Haemodynamic parameters such as HR, SBP, DBP, MBP, ECG and various respiratory parameters such as SpO_2, EtCO_2, PIP and PP were recorded during the study period. 

Results: We found that HR, SBP, DBP, MAP increased significantly following ETT intubation as compared to response after PLMA insertion. There were similar changes observed in haemodynamic parameters during and after insufflation period in both the group. No significant changes observed in SpO₂ throughout study but EtCO₂, PIP, PP showed significant changes after insufflation and 5 min after desufflation in both the groups. There intergroup comparisons were analogous; however return of EtCO2 towards baseline was quite delayed in ETT as compared with PLMA. PIP and PP return towards normal was earlier in ETT group than PLMA group. 

Conclusion: Both PLMA and ETT can be safely used, PLMA can be a better choice as it doesn’t evoke any intubation response, return of EtCO₂ earlier towards baseline than ETT and not showed any added complication to ETT intubation.
