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

Abstract

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 ≥39.5 ℃ ) 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)℃ in the experiment group and (39.50±0.37),(39.13 ±0.80),(38.87 ±0.75)℃ 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 ＜ 0.05 ).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 effect of self-made hypothermic blanket is better than the traditional cooling with ice bag,especially long-term cooling effect and it is cconductive to the rehabilitation of children after cardiac surgery.
