Preoperative Active Warm-Up Measure Can Effectively Reduce Perioperative Hypothermia


preoperative warm-up


The risk of hypothermia is much higher when patients are not properly managed during surgery.

Under the same conditions of anesthesia and surgery, the patient's hypothermia will be different because of the individual constitution. Then, is there any method to screen out such patients with high risk of hypothermia before surgery and focus on prevention?

 

Studies have shown that patients are more likely to suffer from perioperative hypothermia if there are the following factors, which need to be prevented:

1. For elderly patients, due to their slow metabolism and other reasons, the response of the thermoregulatory center will also slow down with age.

2. Neonates, and young children, because the thermoregulation mechanism of children has not been fully developed.

3. For patients whose operation time exceeds two hours, the operation scope is relatively large, resulting in a wide range of body cavity exposure.

4. Patients who need surgery for extracorporeal circulation.

5. Patients with diseases affecting body temperature regulation. (thyroid and diabetes, etc.)

6. Patients requiring massive fluid infusion during surgery.

 

According to the above points, if the patient has one or more, can determine the patient belong to perioperative hypothermia with high-risk patients. When these patients are undergoing anesthetic surgery, should use medical temperature probe to monitor their body temperature in real time, and take a relatively active thermal insulation. The better choice is to advance in determine and prevent in advance.

 

This is because prevention hypothermia is far easier than treatment for perioperative hypothermia and its complications.

 

Specific perioperative hypothermia prevention measures can be referred to as follows:

Equipped with a liquid incubator, infusion and temperature meter, etc., to preheat a large amount of liquid in advance during the operation, to prevent hypothermia caused by infusion of a large amount of cold liquid;

Sufficient thermal insulation blankets, heating blankets and pressure heating air blankets should be provided. Active thermal insulation measures and passive thermal insulation measures should be combined to ensure the stability of the patient's core body temperature during the perioperative period.

Active insulation measures were adopted to minimize the exposure time of patients' body surface during anesthesia induction period and recovery period.
