Brief Summary

The composite warming strategy has a certain effect on preventing hypothermia during cancer liver resection surgery. This study aims to explore the application of compound warming strategy in perioperative nursing of cancer liver resection.

This study will compare two groups: the control group using perioperative forced warming measures, and the experimental group using a composite warming strategy.

Main objective: Intraoperative temperature changes Secondary objective: incidence of complications The investigators' investigated the practicality and effectiveness of a combined warming strategy in open liver resection surgery. In addition, the investigators also conducted a quantitative correlation study on the incidence of hypothermia during the surgical process. This provides evidence-based guidance for the prevention of hypothermia during surgery.

Detailed Description

Research Title: Warming with a Composite Warming Strategy Reduces Intraoperative Hypothermia in Patients Undergoing Open Hepatectomy for Liver Cancer: A Randomized Controlled Study Background: Perioperative hypothermia is a clinical condition characterized by a core body temperature dropping below 36 ° C during the perioperative period, which is a common complication in anesthesia and open abdominal surgery. This state can lead to various perioperative complications, including but not limited to surgical site infections, arrhythmia, and cardiac obstruction.

Main objective: Intraoperative temperature changes Secondary objective: incidence of complications Meaning:The investigators' investigated the practicality and effectiveness of a combined warming strategy in open liver resection surgery. In addition, the investigators also conducted a quantitative correlation study on the incidence of hypothermia during the surgical process. This provides evidence-based guidance for the prevention of hypothermia during surgery. In addition, the investigators also conducted a quantitative correlation study on the incidence of hypothermia during the surgical process.

Innovation: The innovation of this article lies in the first verification of the practicality and effectiveness of the composite warming strategy in open liver resection surgery.

Expected outcome: The practical and effective use of a combined warming strategy in open liver resection surgery. In terms of anesthesia duration, blood loss, fluid replacement, and PACU observation duration, the composite warming strategy may have better results than the forced air warming system.

Primary Outcome Measures

Name	Time	Method
Intraoperative temperature changes	At the beginning of the surgery; every 5 minutes during surgery; after the surgery is completed.	Intraoperative temperature changes: After the surgery begins, a temperature monitoring device (disposable medical temperature sensor provided by the limited company) is inserted into the patient's nasopharynx to record the core temperature, while activating the water blanket and forced air.
