Effects of Preparatory Information Provision Program Combined with Forced-Air Warming Blanket on Body Temperature and Shivering of Elders Receiving Total Knee Arthroplasty

Abstract  This two-group pretest and posttest quasi-experimental research aimed to examine the effect of  preparatory information provision program combined with forced-air warming blanket on body temperature and shivering of elders receiving total knee arthroplasty. The samples were 40 older persons with osteoarthritis receiving total knee arthroplasty operation at Police General Hospital. They were divided into experimental group and control group equally. The control group received conventional care whereas the experimental group received the preparatory information provision program combine with forced-air warming blanket. The instruments using in this study were procedure booklets. Content validity of instruments were approved by five experts. Frequency, percentage, mean, and standard deviation were used for data analysis: The mean score of body temperature before and after implementing program between the experimental group and control group were compared the difference by using independent t-test. Shivering between two groups were compared the difference by using Chi-Square Test. The results revealed that:  The mean score  of body temperature in the experimental group was significantly higher than the control group at the .01 level The shivering in the experimental group and the control group were not significantly different at the .05 level.
