Abstract
The cardiovascular effects and blood levels of intravenous nitroglycerin in mother and foetus were studied in normotensive and hypertensive ewes. Although nitroglycerin produced a reduction in uterine blood flow following a decrease in blood pressure, there was little if any incidence of adverse effects in the foetus. Nitroglycerin was detected in all but two samples of foetal arterial blood but the foetal/maternal artery ratio was only 0.04. Nitroglycerin merits further evaluation for the treatment of acute hypertensive episodes in the preeclamptic patient. Les effets cardiovasculaires et le niveau sanguin maternel et foetal de la nitroglycérine ont été étudiés chez la brebis normotensive et hypertensive. Bien que la nitroglycérine ait causé une diminution du débit sanguin utérin à la suite de la baisse de la tension artérielle, on n’a pu constater que peu ou pas d’effets nocifs sur le foetus. La nitroglycérine a été détectée dans tous les échantillons de sang artériel foetal à l’exception de deux et le rapport entre le sang foetal et maternel n’a été que de 0.04. La nitroglycérine mérite une évaluation plus approfondie pour le traitement de la crise hypertensive de la parturiente pré-éclamptique.Keywords
