[Hemodynamic changes following the injection of lormetazepam under premedication and anesthesia conditions in coronary surgery patients].
Lormetazepam, a new short-acting benzodiazepine, was studied in 30 patients undergoing coronary artery bypass grafting (10 patients before induction of anaesthesia, 8 patients before extracorporeal circulation, 12 patients during extracorporeal circulation). Before induction of anaesthesia lormetazepam caused only a small reduction in CI, heart rate and a moderate hypoventilation. During anaesthesia (fentanyl, pancuronium bromide, ventilation with N2O/O2 1: 1) there was a decrease in CI (26%), SI (18%), HR (5,7%), dp/dt (15%) and an increase in TSR (25%) and TPR (32%); Part, PAP, PCWP and PRA remained unchanged. There was a small decrease in myocardial oxygen consumption. During ECC lormetazepam increased the arterial perfusion pressure (20%); the priming volume of the oxygenator decreased by 48% at the same time, indicating venous pooling.
