摘　　要：目的研究影响脑出血患者术后发生肺部感染的危险因素,探讨前馈控制对感染的预防效果。方法选取2013年1月-2014年12月在医院住院并确诊为脑出血患者540例,按时间分为两组,2013年1-12月为对照组,2014年1-12月为观察组,每组各270例;对照组给予常规干预,观察组则在常规干预的基础上应用前馈控制;比较两组患者的肺部感染情况、住院时间、排痰量、有效排痰液、血压和血氧饱和度(SaO2)水平;采用SPSS17.0软件对数据进行统计分析。结果观察组患者肺部感染率为7.78%,明显低于对照组的12.96%,住院天数更短,两组差异有统计学意义(P<0.05);观察组患者第1天的日均排痰量明显高于对照组,第1天和第3天的有效排痰明显较高,差异有统计学意义(P<0.05);干预前两组患者的血压、SaO2比较差异无统计学意义,干预后观察组患者的SaO2水平高于对照组,差异有统计学意义(P<0.05)。结论前馈控制可以有效降低脑出血患者术后的医院感染率,缩短住院时间,值得在临床推广应用。OBJECTIVE To explore the risk factors for postoperative pulmonary infections in the patients with cerebral hemorrhage and observe the effect of feedforward control on prevention of the infections.METHODS A total of540 patients with confirmed cerebral hemorrhage who were hospitalized from Jan 2013 to Dec 2014 were enrolled in the study and divided into two groups according to the time：the control group（from Jan 2013 to Dec 2013）and the observation group（from Jan 2014 to Dec 2014）,with 270 cases in each.The control group was treated with conventional intervention,while the observation group was treated with additional feedforward control based on the conventional intervention.The incidence of pulmonary infections,length of hospital stay,amount of expectoration,effective expectoration,blood pressure,and blood oxygen saturation（SaO2）were observed and compared between the two groups of patients,and the statistical analysis of data was performed with the use of SPSS17.0software.RESULTS The incidence of pulmonary infections of the observation group was 7.78%,significantly lower than 12.96% of the control group;the length of hospital stay of the observation group was significantly shorter than that of the control group（P〈0.05）.The daily expectoration amount on the first day was significantly higher in the observation group than in the control group,the effective expectorations were significantly high on Day 1and Day 3（P〈0.05）.There was no significant difference in the blood pressure or SaO2 between the two groups before the intervention;the level of SaO2 of the observation group was significantly higher than that of the control group（P〈0.05）.CONCLUSION The feedforward control can effectively reduce the incidence of postoperative nosocomial infections in the patients with cerebral hemorrhage and shorten the length of hospital stay,and it is worthy to be promoted in the hospital.
