Basic systemic hemodynamic parameters were compared during intravenous anesthesia with calypsol (ketamine) and diazepam, promedol and diazepam, fentanyl and diazepam, fentanyl and sombrevin in 120 patients operated on the lungs with conventional and high-frequency jet ventilation. The studies have shown that in conventional controlled lung ventilation there were no distinctions in hemodynamic parameters depending on the type of the anesthesia. In high-frequency jet ventilation, specific hemodynamic effects of calypsol were observed. Unlike other anesthetics, calypsol administration is associated with elevated central venous pressure, increased cardiac output and enhanced left ventricular work, which can be accounted for by higher venous return.
