Abstract

Purpose: The purpose of this study was to evaluate the effect of preoperative warming to prevent hypothermia in surgery for patients undergoing total hip replacement arthroplasty under spinal anesthesia.
Methods: A randomized experimental study was conducted. Data were collected at an S University hospital in Gyeonggido from December 3, 2019 to March 31, 2020. A random allocation program was used to randomize participants into intervention and control groups. A total of 90 participants were assigned to the study: 30 people were randomized to a pre-warming group using Bair Hugger forced-air warming blankets(Model 505) 30 minutes before surgery, 30 to a pre-warming group 15 minutes before surgery, or 30 to a control group. The findings from 88 participants were analyzed. For data analysis, x2 test and ANOVA were used utilizing the SPSS 21.0 program.
Results: The pre-warming group 30 minutes before surgery had significantly higher body temperature than the control group, from 30 minutes after inducing anesthesia to the end of anesthesia. Body temperature over anesthesia time showed significant differences among the three groups, but there were no statistically significant differences in interactions between time and groups.
Conclusion: Warming patients' body for 30 minutes before surgery was effective in maintaining normal body temperature while preventing intraoperative hypothermia.
