目的探讨影响患者机械通气时间的危险因素。方法随机选取在我院使用机械通气治疗的患者63例,根据患者使用机械通气时间的长短分为短期通气组(42例)和长期通气组(21例),分析影响两组机械通气时间的危险因素。结果两组患者浅快呼吸指数、PaCO2、体温、白细胞数、白蛋白等指标均存在明显差异(P<0.05),胸片感染像长期通气组明显多于短期通气组,APACHEⅡ评分、腹胀发生率、并发症(相关性肺炎等)的发生率长期通气组明显高于短期通气组(P<0.05)。结论胸片感染像、低白蛋白、APACHEⅡ评分、并发症、腹胀是影响机械通气时间长短的独立危险因素。
Objective To investigate the risk factors affecting the duration of mechanical ventilation in patients. Methods Sixty-three patients randomly assigned to receive mechanical ventilation in our hospital were randomly divided into short-term ventilation (n = 42) and long-term ventilation (n = 21) according to the duration of mechanical ventilation. The risk of mechanical ventilation factor. Results The fast breathing index, PaCO2, body temperature, white blood cell count and albumin were significantly different between the two groups (P <0.05). The incidences of chest X-ray in long-term ventilation group were significantly higher than those in short-term ventilation group, APACHEⅡ score, , The incidence of complications (related pneumonia, etc.) in the long-term ventilation group was significantly higher than the short-term ventilation group (P <0.05). Conclusions Chest radiography, low albumin, APACHEⅡscore, complications and abdominal distension are independent risk factors affecting the duration of mechanical ventilation.
