老年人术后持续静脉泵入吗啡止痛的应用研究

Continuous iv pumping of morphine to relieve pain for postoperative aged patient.

目前临床上老年人术后止痛常规使用肌肉注射杜冷丁，但不良反应较重，本文采用微量输液泵持续静脉泵入吗啡止痛，两者进行比较。将６０例老年术后病人随机分为２组进行研究，Ⅰ组用微量泵持续静脉泵入吗啡止痛；Ⅱ组采用肌肉注射杜冷丁止痛。观察２４小时内病人的止痛效果及用药后的不良反应。２组在止痛效果上无明显差异，但Ⅰ组不良反应明显少于Ⅱ组，有明显差异（Ｐ＜０．０５）。本组结果显示：老年人术后止痛采用微量输液泵持续静脉泵入吗啡较肌肉注射杜冷丁更安全、可靠、持续有效。

The objective of the study is to compare the effectiveness of two methods in relieving pain in postoperative aged patient. We divide 60 aged postoperative patients into two groups randomly. In group 1 we use micro volume continous infusion pump to give morphine intravenously and in the other group dolantin was given intramuscularly ,We observed the pain relieving effect and the side effect for 24 hours. There was no significent difference in the pain relieving effect, but the side effect was less in group 1 than in group 2 ( P <0 02).We believe that intravenous morphine injection through micro volume infusion pump is safer than intrmuscular dolantin injection.
