[Behaviour of cardiovascular system during obstetric neuroleptanalgesia, using droperidol/fentanyl (author's transl)].

Intravenous injection of 2.5 mg of droperidol and 0,05 mg of fentanyl to ten women with clinically intact cardiovascular system in advanced pregnancy and the cardiovascular effects of such injection were studied by means of quantitative sphygmometry. - Mean arterial blood pressure was found to drop slightly but with significance, while the blood pressure amplitude went up. Heart rates remained largely constant. Significant increase in cardiac output, consequently, resulted solely from increase in stroke volume. Total peripheral resistance was reduced with significance. Medication, using the above combination of drugs, may be recommended for obstetric analgesisa, because of its favourable impact in terms of hemodynamics.
