无线生命体征动态监测系统在ICU危重患者中的应用

目的采用目前最先进的射频识别（RFID）技术，实现体温动态监测，并实时监测患者当前的活动区域。方法90名危重患者实行随身佩戴内置温度感应器的标签，实现患者体温数值的动态采集，采用同期自身对照方法将通过RFID标签监测得到的体温精确度与腋温测量值相比较，并调查两种测温方法模拟每日所需护理耗时。结果不同时间测得体温值，传感器组分别为15min（36．58±0．92）℃，30min（36．69±0．97）℃，60min（37．08±0．85）℃，90min（37．34±1．03）℃，120min（37．45±1．03）oC，150min（36．88±0．97）℃，与水银体温计组相似15min（36．53±0．94）℃，30min（36．75±0．89）oC，60min（37．04±0．92）℃，90min（37．39±0．99）oC，120min（37．41±0．99）℃，150min（36．85±0．89）℃，两组比较差异均无统计学意义（t分别为0．34，-0．86，0．76，-0．54，0．35，0．63；P均〉0．05）；每日所需护理时间，传感器组（23．78±5．57）min，水银体温计组（201．25±16．37）min，两组比较差异有统计学意义（t=-9．75，P〈0．01）。结论采用RFID技术体温动态监测系统，可将实时监测的数据显示在生命体征动态监测系统的监测界面，同时实时向医院信息系统传输体温信息，护士无需在影响患者休息的情况下就可以立即监测到患者当前体温情况，大大减少了护理人员工作量，并能使医生、护士及与患者相关科室之间实现患者信息资源共享。

Objective To monitor dynamic.body temperature and active region of patients by using the most advanced RFID technology.Methods To gather 90 critically ill patients' dynamic body temperature and the axillaries temperature,who wear the built-in temperature sensor label,then to compare measurements and the daily eare required time-consuming in the same period of self-control method.Results The body temperature was (36.58 ±0.92),(36.69 ±0.97),(37.08 ±0.85),(37.34 ±1.03),(37.45 ± 1.03),(36.88 ±0.97) ℃ at 15,30,60,90,120,150 min,respectively,in the transducer group,and (36.53 ±0.94),(36.75 ±0.89),(37.04 ± 0.92),(37.39 ± 0.99),(37.41 ± 0.99),(36.85 ± 0.89) ℃ in the thermometer group,with no statistically significant difference ( t =0.34,-0.86,0.76,- 0.54,0.35,0.63,respectively ; P ＞ 0.05 ) ; daily nursing time was(23.78 ± 5.57 ) miu iu the transducer group and (201.25 ± 16.37) min in the thermometer group,and the difference was statistically significant ( t =- 9.75,P ＜ 0.01 ).Conclusions The RFID technology,that is dynanmic temperature monitoring system,can display the real-time data to monitor interface of vital signs dynamic monitoring system,and transfer temperature information to the HIS system in real time,in that case,nurses can monitor patients' current temperature without affecting patients' sleep,then reducing the workload of nursing staff and sharing patient' s information among the doctors,the nurses and the relevant departments.
