摘要
目的与方法:观察失血性休克犬在普鲁卡因、氯胺酮复合静脉麻醉下60min内体循环和冠脉循环血流动力学及心肌代谢的变化。结果:除外周血管总阻力下降外,其他体循环及冠脉循环血流动力学指标均无明显的改变。动脉血和冠状窦血乳酸含量增加,心肌乳酸摄取速率和摄取率明显上升。结论:在失血性休克状态下应用普鲁卡因、氯胺酮复合静脉麻醉后心血管功能基本稳定在麻醉前水平,心脏后负荷有所降低,心肌氧供略增,氧耗稍减。
Objective and Methods: The study was done to evaluate the systemic, coronary hemodynamics and myocardial metabolism responsing to intravenous procaine, ketamine anesthesia in hemorrhagic dogs. Results: As compared with preanethetic data, the systemic and coronary hemodynamics remained relatively stable. TPRI somewhat decreased. La.art, La.cs, MMRLa and MRLaextra increased correspondingly. Conclusion: The cardiovascular function remains stable after anesthesia. The myocardial blood flow does not increased, but the supply of myocardial oxygen is satisfactory by increasing MO 2avail and decreasing MVO 2.
