What is the golden rule in perioperative temperature management?




Before we start, we need to put out today’s question first:


Q: What is the golden rule in perioperative temperature management?

A: Core body temperature monitoring and active insulation measures constitute the golden rule of perioperative body temperature management.

Q: So, how do you understand this golden rule?


In recent years, perioperative body temperature monitoring and body temperature management have received the attention of clinicians. 

Core body temperature monitoring and active insulation measures constitute the golden rule of perioperative body temperature management. 

This golden rule can be summarized in one sentence, namely body temperature. The measurement is accurate and the insulation is well done.



Body temperature measured accurately

We all know that the human body’s normal core body temperature is between 36.5°C and 37.5°C. “The body temperature is accurately measured.” The body temperature here does not refer to the measurement of the body surface temperature, but the use of a medical temperature probe to monitor the patient’s core body temperature for 24 hours.

We all know that anesthetics can inhibit the body's autonomic nervous system and reduce metabolism, thereby weakening the body's response to temperature.


Core body temperature lower than 36°C is defined as accidental hypothermia during the perioperative period.

During the perioperative period, core body temperature drop is a common situation, with a rate as high as 60% to 70%. But this does not mean that medical staff can relax the control of the core body temperature of patients during the perioperative period, because the various complications caused by hypothermia cannot be ignored.



Good insulation

Perioperative insulation measures are divided into passive insulation and active insulation. The most common behaviors such as blankets are passive insulation measures.

Active thermal insulation measures can be divided into body surface thermal insulation (such as the application of active inflatable heating blankets) and internal thermal insulation (such as warming blood transfusion, warming abdominal cavity washing fluid).

Core body temperature monitoring combined with active thermal insulation measures is an important method for perioperative body temperature protection.
