术前视频访视对ICU患者术后焦虑、心率、血压及谵妄的影响

摘要

目的 探讨ICU视频术前访视对患者情绪、心率、血压及谵妄发生率的影响.方法 选择我院ICU 2015年1月—2016年3月收治的患者188例,按照随机数字表法分为两组,实验组90例,接受ICU视频术前访视,对照组98例接受常规术前访视.比较两组患者访视前及术后意识恢复后焦虑情绪、心率、血压及谵妄发生率.结果 术后意识恢复后实验组中重度焦虑患者14例,对照组26例,差异有统计学意义(Z=2.079,P<0.05);意识恢复后实验组患者心率为(71.18±5.65)次/min,收缩压(124.44±10.76)mmHg,均低于对照组,差异有统计学意义(t值分别为10.8915、6.4448;P<0.05).实验组患者术后谵妄发生率6.67%,对照组为22.45%,两组比较差异有统计学意义(χ2=4.610,P<0.05).结论 ICU视频术前访视可有效缓解患者焦虑情绪,促进患者血压、心率平稳,减低患者谵妄发生率,值得临床推广应用.%Objective To explore the effects of preoperative video interview on postoperative anxiety, heart rate, blood pressure and delirium in ICU patients.Methods A total of 188 patients in ICU were divided into experimental group (n=90, preoperative video interview of ICU) and control group (n=98, routine preoperative interview) with the method of random number table between January 2015 to March 2016. The anxiety, heart rate, blood pressure and incidence rate of delirium of patients were compared between groups before interview and after operation when patients' consciousness recovered.Results There were 14 patients with moderate or severe anxiety in experimental group and 26 in control group with a significant difference (Z=2.079,P<0.05) after consciousness recovered. Moreover, heart rate, heart pressure and the incidence rate of delirium in experimental group[(71.18±5.65) times/minute, (124.44±10.76)mmHg, 6.67%] were all lower than those in control group with significant differences (t/χ2=10.8915, 6.4448,4.610;P<0.05). Conclusions Preoperative video interview of ICU can effectively relieve anxiety, improve heart pressure and heart rate, reduce the incidence rate of delirium of patients. It is worthy of being generalized and applied.
