摘要
目的探讨先天性心脏病肺动脉高压患者围术期肺换气功能的特点及呼吸机的合理使用。方法４３例室间隔缺损（ＶＳＤ）患者分为肺动脉高压组（２３例），对照组（２０例），对其围术期呼吸指数进行动态观察与分析。结果肺动脉高压组呼吸指数术后１小时降至较低水平后又逐渐增高，在术后１２小时达到高峰后逐渐下降，２４小时基本达到术前水平呈明显不稳定状态，而对照组相对平稳。结论肺动脉高压患者术后２４小时内肺换气功能处于不稳定状态，延长呼吸机辅助呼吸时间有利于渡过术后危险期。
Objective In order to observe the postoperative respiratory character of the patients with lefttoright shunting heart diseases and pulmonary hypertension, and to apply respirator properly. Methods 43 patients with ventricular septal defect were divided into pulmonary hypertension group (23 patients) and control group(20 patients) to be analysed for their respiratory index changes in different time in the operation. Results The respiratory index reduced to the lowest level at the first postoperative hour and then, gradually increased to the peak at the 12th postoperative hour. Thereafter, it reduced gradually again. At the 24th postoperative hour it returned to the preoperative level.Comparatively the control group did not showed fluctuation of the indices. Conclusion The patients with pulmonary hypertension have an unstable respiratory function in the first 24 hours after the operation. A longer time mechanical ventilation is helpful for the patients to pass this dangerous period safely.
