Abstract
We infused lidocaine intravenously into 13 pregant ewes at a rate sufficient to maintain plasma levels between 2-4 μgm/ml, which are those commonly seen with regional anaesthesia. These levels did not change maternal blood pressure, pulse rate, cardiac output, stroke volume, total peripheral resistance, uterine blood flow or intra-amniotic pressure. Foetal blood pressure and pulse rate remained stable as did both maternal and foetal blood gases and acid-base values. Treize brebis en gestation ont reçu une perfusion intraveineuse de Lidocaïne. La perfusion était ajustée à un débit suffisant pour maintenir le taux plasmatique de Lidocaïne entre 2 et 4 μg/ml, taux que ľon rencontre habituellement en clinique sous anesthésie régionale. Dans ces conditions, nous n’avons pas observé chez la mère de modifications de la pression artérielle, de la fréquence cardiaque, du débit cardiaque, de la résistance périphérique totale, du débit sanguin utérin et de la pression du liquide amniotique. Du côté du foetus la pression artérielle et la fréquence cardiaque sont demeurées stables. Les gaz artériels et ľéquilibre acido-basique n’ont pas été modifiés, tant chez la mère que chez le foetus.Keywords
