为了观察氯胺酮、安定静脉复合麻醉对小儿血流动力和呼吸功能的影响，选择４６例中小型手术的患儿，用Ｐａｓｓｐｏｒｔ多导监护仪连续监测ＢＰ、ＨＲ、ＳＰＯ２和用ＴＥＰＬｕｓ呼气末二氯化碳浓度监测仪连续监测ＰＥＴＣＯ２、Ｒ。结果：麻醉后ＢＰ升高、ＨＲ增快，麻醉前后有显著性差异（Ｐ＜０．０１）；ＢＰ增高值与麻醉前相比小于１０％的有７例，１０％～２０％的有３３例，２０％～２４％的有６例，ＨＲ增快值均小于１５次／ｍｉｎ；Ｒ减慢、ＳＰＯ２＞９５％、ＰＥＴＣＯ２＜５．７３ＫＰａ在临床允许值范围内，麻醉前后无显著性差异（Ｐ＞０．０５）。作者体会：氯胺酮、安定静脉复合麻醉对小儿血流动力学和呼吸影响甚微，是简便、安全、实用的小儿麻醉方法。
In order to observe the effect of ketamine and diastolic anesthesia on pediatric hemodynamics and respiratory function, 46 children with small and medium-sized surgery were selected. Continuous monitoring of BP, HR, SPO2 and TEPLus end- Carbon concentration monitor Continuous monitoring of PETCO2, R. Results: After anesthesia BP increased, HR increased rapidly, there was significant difference before and after anesthesia (P <0.01); BP increased compared with pre-anesthesia less than 10% in 7 cases, 10% to 20% of 33 Cases, 20% to 24% in 6 cases, HR increased faster than 15 times / min; R slowed, SPO2> 95%, PETCO2 <5.73KPa within the allowable clinical range, no significant difference before and after anesthesia (P> 0.05). The author’s experience: ketamine, stable intravenous anesthesia on pediatric hemodynamics and breathing little, is simple, safe and practical method of pediatric anesthesia.
