However, few studies were related to hypothermia in Taiwan. The purpose of this study was to investigate the effects of prewarming on perioperative hypothermia prevention in abdominal surgery patients. A randomizes block assignment design was used for this study. Forty-two abdominal surgery subjects (23 patients for experimental group; 19 patients for control group) were recruited from a medical center operation room in Taipei area. A questionnaire including demographic characteristics, operative situations and anesthesia situations was used to collect data. The data for trend change and related factors were analyzed by Generalize Linear Model to Generalize Estimating Equation using SAS 9.0 version software package. The chi-square, t-test, survival function using SPSS 14.0 software package were also used. The results were as follows: 1) prewarming for thirty minutes with force air warming, the body temperature in the experimental group was statistically significant higher than the control group; 2) prewarming with force air warming for thirty minutes to maintain interoperative body temperature was statistically significant for the laparoscopy surgery; but no effect on the exploratory laparotomy surgery; 3) there was no significant effect on body temperature all subjects; the body temperature in the experimental group was higher than the control group, but the result was not statistically significant; there was no significantly different in the exploratory laparotomy surgery; 4) prewarming with force air warming for thirty minutes could decrease the incidence of postoperative hyperthermia on subjects with laparoscopy surgery, but the result was not statistically significant in the exploratory laparotomy surgery. In conclusion, prewarming with force air warming for thirty minutes can maintain body temperature when the subjects received laparoscopy surgery, and the body temperature in the laparoscopy group had a trend to keep higher temperature than the control group, but the result was not statistically significant. In terms of the findings, the effects of prewarming still need further study in the future.
