Сomparative analysis of respiratory support for endoscopic sleeve gastroplasty in patients with morbid obesity

Abstract

For the analysis of the effect of respiratory support on the parameters of external respiration, gas exchange, peripheral and central hemodynamics in endoscopic sleeve gastroplasty in patients with morbid obesity a randomized study of 58 patients with morbid obesity was conducted, in which endoscopic sleeve gastroplasty was performed under combined anesthesia. Depending on the choice of the mode of pulmonary ventilation (PV), the patients were divided into two groups. In the 1st group (n = 28) patients had respiratory support in the volume-controlled ventilation mode (VCV); in the 2nd group (n = 30) they had respiratory support in the pressure-controlled ventilation (PCV) mode. The parameters of central hemodynamics, external respiration, peripheral hemodynamics, ABB were monitored intraoperatively. It was found that a significantly higher level of oxygenation was detected with PCV mode: PaO2 - 96.8 (92.7; 99.8) mm Hg, (PaO2/FiO2) 322.6 (341.2; 304.7) mm Hg in comparison with VCV mode: PaO2 - 92.2 (87.5; 96.3) mm Hg, PaO2/FiO2 - 307.3 (286.2; 331.7) mm Hg, and in second stage of the study (p < 0,05).
