脉波指示剂连续心排量监测在重度胸外伤并发急性呼吸窘迫综合征治疗中的应用

摘要

目的:观察脉波指示剂连续心排量(PICCO)监测在重度胸外伤并发急性呼吸窘迫综合征(ARDS)治疗中的应用效果.方法:选取60例重度胸外伤并发ARDS患者,将其随机分为PICCO组和肺动脉导管(PAC)组,每组30例.观察两组氧合指数(PaO2/FiO2)和急性生理学年龄和慢性健康评估Ⅱ(APACHEⅡ)评分,比较两组患者病死率、机械通气时间、入住ICU时间以及总治疗费用等差异.结果:PICCO组的PaO2/FiO2在治疗1 d、3 d和7 d时均明显高于PAC组,差异有统计学意义(t=4.46,t=3.87,t=5.15;P<0.05).PICCO组治疗7 d时的APACHEⅡ评分明显低于PAC组,差异有统计学意义(t=1.94,P<0.05).PICCO组机械通气时间、入住ICU时间和总治疗费用均明显低于PAC组,差异具有统计学意义(t=3.36,t=2.58,t=5.53;P<0.05),而两组的病死率比较差异无统计学意义(x2=0,P>0.05).结论:在重度胸外伤并ARDS患者的治疗中,PICCO监测有助于减少患者机械通气时间、入住ICU时间和总治疗费用,提高患者的治疗效果.%Objective:To observe the application of pulse indicator continuous cardiac output (PICCO) system monitoring in the treatment of patients with severe thoracic trauma with the complication of acute respiratory distress syndrome (ARDS).Methods: 60 patients with severe thoracic trauma with complication of ARDS were randomly divided into the PICCO group (30cases) and the PAC group (30cases). The differences of PaO2/FiO2 score, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, mortality, mechanical ventilation time, ICU stay time and total treatment cost between the two groups were observed.Results: The PaO2/FiO2 of PICCO group in 1d, 3d and 7d were significantly higher than that of PAC group, respectively (t=4.46,t=3.87, t=5.15,P<0.05). In the 7th day, the APACHE II of PICCO group was significantly lower than that of PAC group (t=1.94,P<0.05). Besides, the mechanical ventilation time, ICU stay time and total treatment cost of PICCO group were significantly lower than these of PAC group, respectively (t=3.36, t=2.58,t=5.53,P<0.05). While there was no difference for mortality between the two groups (x2=0,P>0.05). Conclusion: In the treatment for patients with severe thoracic trauma with ARDS, PICCO system monitoring could reduce the mechanical ventilation time, ICU stay time and total treatment costs of patients, and enhance the treatment effect of patients.
