Abstract
The purpose of the studies was to compare and evaluate the effect of different anesthesia protocols for operative delivery in dogs. The studies were performed on 60 pregnant females of different breeds aged 2 to 6 years, with an average weight of 22 ±4.6 kg. Animals were divided into three groups, 20 in each. Animals of the first group for the introduction and maintenance of general anesthesia used Propofol at a dose of 4-6 mg/kg. Animals of the second and third groups were introduced into anesthesia using inhalation anesthetics through a mask, then tracheal intubation was performed and general anesthesia was maintained by an anesthetic-respiratory apparatus. In the second group, Isoflurane 0.5 - 2.0 vol% was used as the main anesthetic; in the third group, Sevoflurane 1.0 - 2.0 vol%. Sevoflurane had the least impact, minimally deviating the studied parameters from the original data. The greatest changes were always observed when administered to anesthesia, manifesting as moderate and severe hypoxemia and hypercapnia. Analyzing the data obtained, we concluded that the use of inhalation anesthetics isoflurane and, in particular, sevoflurane, during caesarean section is preferable due to their less pronounced effect on gas composition and acid-base blood composition.
