The aim of the study was a comparative study of the status and changes of parameters of external respiration at carrying out of endoscopic surgery for tubal infertility using low-flow sevoflurane- or desflurane-based anesthesia, the application of epiglottis duct I-gel and the mode of ventilation with pressure support (PS). Investigated 100 patients with tubal infertility, which produced surgical treatment of infertility under General sevoflurane- or desflurane-based anaesthesia, using epiglottis duct and the use of ventilation with pressure support (PS). The study results showed that when conducting low-flow sevoflurane- or desflurane-based anesthesia with maintained spontaneous breathing through the epiglottis duct, the changes of parameters of the biomechanics of respiration in both groups are of unidirectional character and the highest values of deviation from the source parameters at the third stage of the research (15 minutes after the imposition of carboxyperitoneum), however, do not affect the gas exchange that shows the safety of these methods of anesthesia and the possibility of their application in everyday clinical practice.
