Haemodynamic stability during anaesthesia induction and sternotomy in patients with ischaemic heart disease. A comparison of six anaesthetic techniques.
A comparison of haemodynamic stability with respect to arterial pressure, heart rate and cardiac output between six commonly used anaesthetic techniques: fentanyl (FE), halothane (HAL), morphine (MO), fentanyl/droperidol (NLA), and thiopentone (two dose levels: PE 3 and PE 6), all supplemented with nitrous oxide, was performed during induction of anaesthesia and sternotomy in 47 patients with good left ventricular function and maintained beta-blockers undergoing coronary bypass surgery. Interventions were kept to a minimum in order to characterize each anaesthesia group. Statistically, the material fell into two parts. The MO, PE 3 and PE 6 groups showed good stability under steady-state anaesthesia, but variable and often extensive hyperdynamic responses were seen to endotracheal intubation and surgical stimulation. The FE, HAL and NLA groups were characterized by a good stability during the induction-intubation phase but were unstable when combined with nitrous oxide in the absence of noxious stimuli.
