Best Recommended Method for Perioperative Temperature Monitoring


The experts suggest that the perioperative temperature monitoring should be included in the routine intraoperative monitoring index, which indicates the importance of intraoperative temperature monitoring.


What factors should be considered for the site of temperature monitoring?

As we know, due to the differences of body temperature in different parts of the body, the core temperature is more uniform and accurate than the peripheral and skin temperature, which can more accurately reflect the body's thermal state.

Therefore, the focus of perioperative period is to monitor the patient's core temperature, and the most recommended method is to use a medical disposable temperature probe connected with a monitor to monitor the patient's core temperature in real time.


Here are the pros and cons of several temperature monitoring tools and methods:


Mercury thermometer

It was once the most common clinical temperature monitoring tool, because it is simple to operate, easy to buy, easy to use.

But it has been phased out because of its low accuracy and the risk of mercury leakage.


Infrared thermometer

Infrared thermometer is most commonly used in the measurement of tympanic membrane temperature. Its product characteristics determine the rapid response to temperature measurement, and there is a good consistency between the measured temperature and the central temperature.

And the measurement is simple and does not cause discomfort.

It can be used to measure the temperature of patients when they are awake before and after surgery, but the disadvantage is that continuous measurement cannot be carried out to achieve real-time monitoring.


Noninvasive body temperature probe monitoring system

The new body temperature probe can be attached to the body surface and insulate the loss of body surface temperature through heat insulation material, forming isothermal effect of core temperature and body surface temperature, and thus recording the core temperature. Its biggest advantage is that it can continuously transmit the temperature data to the monitor to realize real-time temperature monitoring.


Proper temperature monitoring should have a dynamic continuity that covers preoperative, intraoperative, and postoperative measurements.

Experts suggest that patients' body temperature should be monitored in real time before surgery to provide reference data for pre-insulation.

Intraoperative attention should be paid to the changes in patients' body temperature to prevent the sequelae caused by hyperthermia or hypothermia.

Postoperative temperature monitoring is also very important, not only to evaluate the effect of intraoperative thermal insulation measures, but also to provide good conditions for follow-up treatment.
