The cardiovascular and respiratory responses to electrical stimulation of the buccal mucosa under general anaesthesia in ponies were measured in order to provide some insight into the cardiorespiratory effects of anaesthesia in equidae. This knowledge may be useful for reducing morbidity during clinical anaesthesia in horses. Anaesthesia was induced with intravenous thiopentone and maintained with 1.3 per cent inspired halothane in oxygen. Arterial blood pressure, heart rate, minute volume, tidal volume, respiratory rate, arterial blood gas tensions and clinical signs of anaesthetic depth were recorded while the buccal mucous membrane was stimulated electrically. A rise in arterial blood pressure was the most consistent response detected along with clinical signs. The response of individual animals varied considerably. Alterations of respiratory pattern sometimes occurred during stimulation but there was no consistent pattern of change in any animal.
为了深入了解马科动物麻醉对心肺的影响，对小马在全身麻醉下电刺激颊黏膜时的心血管和呼吸反应进行了测量。这些知识可能有助于降低马匹临床麻醉期间的发病率。静脉注射硫喷妥钠诱导麻醉，并用1.3%的氟烷与氧气混合维持麻醉。在电刺激颊黏膜时，记录动脉血压、心率、每分通气量、潮气量、呼吸频率、动脉血气张力和麻醉深度的临床体征。动脉血压升高是最一致的反应，同时伴有临床体征。个体动物的反应差异很大。刺激过程中有时会出现呼吸模式的改变，但任何动物都没有一致的变化模式。
