Abstract

The proseal laryngeal mask is designed with many advantages that ensure a better ability to maintain ventilation. However, the anesthesiologist still concerned about maintaining ventilation in the lateral position for percutaneous nephrolithotripsy. Prospective, randomized clinical intervention study was conducted to compare the ventilation efficiency between proseal laryngeal mask and endotracheal tube. 60 patients, divided into 2 groups, underwent percutaneous lithotripsy at Vinh Phuc General Hospital from February to August 2020. Results: some anthropometric indices and surgery time were similar in the 2 groups. After lying on the side, the peak airway pressure increased, the lung compliance decreased, although the difference at each time point in the two groups was not statistically significant difference. Leakage volume (Vh %) in the laryngeal mask group was always higher than in the endotracheal group, the difference was statistically significant with p < 0.05. The change in leakage volume was not increased after postural change in each group. However, this leakage volume was not large and does not cause ventilation disturbances as well as gas exchange disorders. Conclusion: the proseal laryngeal mask had a higher leakage volume but still maintained ventilation and gas exchange compared to endotracheal intubation in patients undergoing percutaneous lithotripsy in the lateral position.
