The warmth during the operation is like the sunrise sunlight

A few days ago, when the family party, the aunt said that she had a general anesthesia surgery some time ago. As soon as she entered the room, she trembled coldly. After the anesthesia woke up, she couldn't control her shaking. After listening to the uncle, he said, "The son of my colleague's son for a few days ago was the same after a few days ago. When the young man just returned to the ward, his teeth trembled and shouted. Everyone said that the temperature of the air conditioner was not very low. Why does the young man look like that? "

actually……

Coldness is the reason why the patient's body temperature decreases, especially the core temperature decreases. At this time, it can only accelerate the production of calories through a chilling reaction. We cannot simply think that it is caused by air -conditioning refrigeration. Below, this article briefly talks about the role and significance of temperature monitoring and warmth during the technique.

What is too low in body temperature?

The body temperature of the normal human body is relatively constant, maintaining fluctuations between 36.3 ° C-37.2 ° C. Normal body temperature is a necessary condition for the body to metabolize and normal life activities. It is the human body that maintains constantness through autonomy and behavioral temperature regulation function. However, in the state of anesthesia, patients lose their behavioral temperature regulation function (such as adding clothing or quilts, which are not conducive to performing surgery), and can only rely on their own body temperature regulating central regulating the body's heat production and heat dissipation process. The heat production can achieve the purpose through the metabolism and muscle contraction of the liver, and the liver and muscle function can be basically suppressed under anesthesia, and the increase in heat production is limited. The heat dissipation mainly emits heat through the sweat glands of the body. The naked exposed area of ​​the body surface in the anesthesia state increases, and the temperature of the air conditioner is low. At this time, the heat dissipation increases significantly. This reduced heat eventually caused the body temperature to be easily decreased. When it was lower than 36 ° C as the low body temperature, some studies found that the perinatal temperature was too low to 50%-80%, so we must pay attention to the body temperature Protect.

What are the hazards of decreased body temperature?

Generally speaking, the body temperature is reduced in the following hazards, such as:

1. Decreased body temperature directly leads to the decline in liver and kidney function, affects the decomposition and metabolism of anesthesia drugs, and easily leads to the accumulation of anesthesia drugs, affects the recovery of anesthesia or even wake up;

2. Temperature complications such as lung infection and other respiratory systems, increasing the incidence of cardiovascular adverse events;

3. Low temperature cause abnormal coagulation factor function, acid -base balance disorders, and inhibit immune function.

Therefore, it is important to maintain appropriate body temperature during the operation to strengthen the body temperature by strengthening the body temperature.

What are the reasons for the decrease in body temperature?

1. Patients themselves: infants and young children, elderly people, combined body infections, patients with critical illness, and patients with large -scale burns and other skin integrity are all prone to low -body temperatures. For such fragile patients, they must strengthen their temperature body temperature Protect.

2. Anesthesia and anesthesia medication: Anesthesia and in -spinal anesthesia can affect the body temperature regulation mechanism. At the time of general anesthesia, the body's hypothalamic body temperature adjustment center, blood vessel movement, and skeletal muscle movement are suppressed. At this time, the body temperature is easy to change with the ambient temperature. When anesthesia in the spinal canal, the fiber of the anesthesia blocking the sympathetic sympathetic fiber of the venom section makes the blood vessel expansion in the block, and the body temperature is distributed around the body. At this time For long -term surgery, it is easy to have a contradictory phenomenon of trembling but not feeling cold.

3. Surgical and blood transfusion and other factors: During the disinfection of the surgical site, due to the exposed skin and the scrubbing and volatilization of cold disinfection, the patient's temperature will be taken away. During surgery, the cold liquid rinse the chest and abdomen cavity or body cavity for a long time, which will cause a large amount of calories. A large amount of infusion of unprooped liquid during the operation can cause body temperature to decrease. In addition, in some endoscopic surgery of urology and obstetrics and gynecology, a large amount of irrigation room temperature is also easily reduced in body temperature.

How does our hospital prevent low body temperature during the perioperative period?

1. Better assessment and pre -heating before surgery: fully evaluate the possibility of patients with low body temperature in patients' condition, surgery and anesthesia, and surgery time before surgery, and take insulation measures. When necessary, the patient's preheating thermal insulation during the transfer of patients to reduce the exposure of patients at a low temperature environment.

2. According to national standards, the ambient temperature of the control room temperature is between 22 ° C and 25 ° C. Special patients such as newborn, premature babies, and old age will appropriately adjust the room temperature.

3. For surgery with time ≥1 hours, the body temperature probe using nasopharynx, oral throat, rectal, etc., continuously monitors the body temperature during the operation to maintain the body temperature in the normal range.

4. Institute of insulation artifacts in the operating room: For patients who are prone to low -body temperature in the preoperative assessment, they can actively warm up measures such as heating blankets, heating fans, and cotton cotton cuffs to reduce the loss of heat in patients and avoid lower body temperature reduction. Essence

5. Use the liquid to warm the equipment to warm the cold liquid, library blood, and body cavity flushing liquid. The heating mode is heating in the heating strip, and the water bath is heated.

Significance of body temperature protection

Maintaining suitable body temperature during surgery and prevention of low body temperature during perioperative period can not only reduce the impact of low body temperature complications, reduce the occurrence of patient cold tremor, but also improve the comfort of patients after anesthesia, reduce surgical infection, promote the promotion Rehabilitation after surgery. During the operation, the insulation is like the sunlight, which makes people enjoy the warmth and comfort of bathing the sun, meet the requirements of comfortable medical treatment, and more humane, but this requires every anesthesiologist to strengthen the awareness of body temperature protection.
