Abstract
The investigators examined the effect of infusing continuously warmed (ie, 37.0° C [98.6° F]) IV fluids in two groups of middle‐aged female patients undergoing laparoscopic cholecystectomy procedures. They hypothesized that increasing IV fluid temperature during surgery would decrease patients' risk for hypothermia. One group of patients received prewarmed IV fluids that cooled to room temperature during surgery. The second group received IV fluids that were warmed continuously by a fluid warmer during the surgical procedures. Analyses of covariance, with the first intraoperative temperature measurement treated as the covariate, revealed nonsignificant results at the P <.05 level. The results suggest that administering continuously warmed IV fluids intraoperatively has no significant effect on maintaining patients' body temperatures during short laparoscopic surgical procedures.
