自制降温毯在小儿心脏术后应用的效果

目的观察心脏术后高热患儿使用自制降温毯的临床效果。方法选择心脏术后高热（肛温I〉39．5℃）患儿80例，按照随机数字表法随机分成对照组（n=40）和试验组（n=40）。试验组采用自制降温毯进行物理降温，对照组采用传统冰袋在头部、腋下等部位进行物理降温，比较采取降温措施后1，4，8h两组患儿的体温及心率。结果与降温前比较，试验组患者在1，4，8h后体温分别为（39．03±0．34）、（38．504-0．39）、（37．99±0．45）℃，对照组分别为（39．50±0．37）、（39．13±0．80）、（38．87±0．75）℃，两组比较差异有统计学意义（t分别为5．75，4．42，6．33；P均〈0．05）。试验组患者在1，4，8h心率均有所降低，与对照组比较在1h时差异无统计学意义，在4，8h时差异有统计学意义（t分别为2．58，3．69；P均〈0．05）。试验组患者在降温8h后体温降低幅度大于1h和4h，也大于对照组相应时段。结论应用自制降温毯降温效果优于采用传统冰袋降温，尤其是远期降温效果明显，有利于心脏术后患儿顺利康复。

Clinical effect of the self-made hypothermic blanket on temperature lowering for children with high fever after cardiac surgery

Objective To observe the clinical effect of self-made hypothermic blanket on children with high fever after cardiac surgery. Methods Eighty children with high fever after cardiac surgery （anus temperature I〉39.5 ~C ） were randomly divided into experiment group and control group. The experiment group used self-made hypothermic blanket to cool and the control group used the traditional ice bag on the head, armpits and other parts to cool. To monitor children＇ s body temperature and heart rate after 1 hour, 4 hours and 8 hours. Results The temperature at 1 hour, 4 hours and 8 hours were （39.03 ±0.34）, （38.50±0.39） and （37.99±0.45）°C in the experiment group and （39.50±0.37）, （39.13±0.80）, （38.87±0.75）°C in the control group, respectively; and the differences were statistically significant （ t = 5.75, 4.42, 6. 33 ; P 〈 0. 05 ）. Heart rate reduced at 1 hour,4 hours and 8 hours, but compared with that in the control group, the difference was statistically significant at 4 hours and 8 hours （ t = 2. 58,3.69 ; P 〈 O. 05 ）. The cooling amplitude of the experiment group at 8 hours was obviously higher than that at 1 hour and 4 hours and that in the control group. Conclusions The cooling effeet of self-made hypothermic blanket is better than the traditional cooling with ice bag, especially long-term cooling effect and it is cconduetive to the rehabilitation of children after cardiac surgery.
