精神分裂症暴力行为的心理行为干预方法研究

目的探讨3种不同呼吸机湿化管道系统对建立人工气道机械通气患者湿化效果的影响。方法收集建立人工气道机械通气48h以上患者90例，随机分为A、B、C3组各30例。A组使用MR410型（吸气与呼气管路均无加热丝）湿化管道系统；B组使用MR730型（吸气管路带加热丝而呼气管路无加热丝）湿化管道系统；C组采用MR850型（密闭式一次性、双加热式自动加水、加湿）湿化管道系统。3组湿化液均使用灭菌注射用水。对3组气道分泌物黏稠度、管道痰痂形成及气道痉挛情况进行比较。结果3组患者在气道分泌物黏稠度、管道痰痂形成、气道痉挛等方面的比较，差异有统计学意义（P〈0．01）；C组无管道痰痂形成，亦无气道痉挛发生。结论机械通气患者呼吸道湿化效果与呼吸机管道湿化系统的管道是否有加热丝有关，加热湿化系统管道，有利于改善气道湿化效果。

Study of psychological behavior intervention methods on the violence behavior of schizophrenia patients

Objective To discuss the psychological behavior intervention methods on reducing the violence behavior of schizophrenia patients. Methods 120 schizophrenia patients were admitted from January to December, 2007 and randomly assigned into the behavior intervention group (group A), the psy-chological support group (group B), the health education group (group C) and the control group (group D) with 30 cases in each group. Group A received routine nursing plus behavior intervention, group B was giv-en routine nursing plus psychological support, group C adopted routine nursing plus health education, group D only received routine nursing. The intervention effect was evaluated with MOAS and the relapse rate of violence behavior went through statistics. Results After intervention, the scores of MOAS decreased sig-nificantly in group A, B, C and D compared with those before intervention. The reduction of MOAS scores in group A, B and C was significantly higher than that of group D, with the highest reduction score in group A and group B and C followed subsequently. The relapse rates of the violence behavior in group A, B and C were significantly lower than those of group D. Conclusions Routine nursing, health education, psycho-logical support and behavior intervention can all reduce and decrease the violence behavior and the inci-dence of the violence behavior, among which behavior intervention proves to be the most effective, and psy-chological support and health education go subsequently.
