Warming with a composite warming strategy reduces intraoperative hypothermia in patients undergoing open hepatectomy for liver cancer: A randomized controlled study.

BACKGROUND

This study investigated the application of a composite warming strategy in the perioperative care of patients who underwent open hepatectomy for liver cancer. The clinical efficacy of the composite warming strategy was observed and analyzed, and the factors causing hypothermia were discussed.

METHODS

From January 2020 to December 2021, 80 patients were selected for the study. The control group adopted perioperative forced-air warming measures, while the experimental group implemented a composite warming strategy. The clinical data of the 2 groups of patients were compared, and the factors influencing intraoperative hypothermia were explored.

RESULTS

The incidence of hypothermia in the composite warming strategy group was significantly lower than that in the forced-air warming group (P = .015). There were no significant differences in sex, age, BMI, stage of liver cancer, presence of liver cirrhosis, chronic hepatitis, history of alcohol consumption, PLT, PT, pain score, length of hospital stay, etc, between the 2 groups (P > .05). However, there were significant differences in intraoperative fluid volume, anesthesia time, intraoperative blood loss, and PACU observation time (P < .05). Multivariate analysis revealed that intraoperative blood loss, intraoperative fluid replacement volume, and operation time were factors influencing intraoperative hypothermia (P < .05).

CONCLUSION

The composite warming strategy plays a role in preventing hypothermia during open hepatectomy for liver cancer. The occurrence of hypothermia during open hepatectomy for liver cancer patients is related to intraoperative blood loss, intraoperative fluid replacement volume, and anesthesia time.
