摘要
对３４例５０岁以上开胸手术病人进行分析，以探讨术中发生非容量性低血压原因，结果：非容量性低血压的发生与体位变换关系密切（Ｐ＜０．００５），与术前伴有高血压、小气道功能异常有一定关系（Ｐ＜０．０５），５０岁以上与６０岁～６９岁年龄组之间非容量性低血压发生率无差异（Ｐ＞０．０５）。预防措施：①摆放最佳的麻醉、手术体位，且动作轻柔；②对术前伴有高血压病人，术中应实施专业性的护理；③协助麻醉医师做好呼吸道管理。
Occurrence of non-quantitative hypotension in 34 patients aged 50 or more who received thoracotomy was analysed.As a result,the occurence of non-quantitative hypotension was closely related to postural alternation (P<0.005),and to preoperative suffered hypertension (P<0.05),the occurrence of this hypotension was similar in the two age group:50 and 60 years.It is suggested that:(1)be softly put the patient at a best anesthetic and operative posture;(2)during operation be specially care for the patients with hypertension;and (3)be help the anesthetist to well handle respiratory tract.
