It is important, for some patients, to measure their body temperature and the changes in it in order to understand if it is normal or not after surgery. Some have conditions that affect the metabolism of the body and they will have a different range of temperatures each day.
When your immune system detects an infection, it signals the hypothalamus, and a fever is created. You can tell if you are fighting an infection by checking for subtle higher temperatures.
When your body temperature falls below normal, it’s a sign that your body doesn’t have the energy to burn healthy tissue and fight off infection.
Postoperative fever is a temperature higher than 102.2 F on any day after surgery or 100.4 F on any two consecutive days after surgery. Fever after surgery is very common. Most cases are harmless and go away on their own.
Postoperative fever occurs in up to 90% of people who have surgery. Any type of surgery causes injury and inflammation. Part of your body’s response to this injury and inflammation can be fever. Aside from this inflammatory response, atelectasis is the most common cause of postoperative fever.
You can expect to have a slight fever in the first 2 days after you have surgery. Unless you have other symptoms as well, your doctor will probably monitor your condition. You likely won’t need a workup. There is no need to worry too much, you just need more rest after surgery, reasonable diet and nutrition, and routine antibiotic anti-infective treatment.
The correct way to reduce fever should be:
Maintain indoor air circulation: If the home is air-conditioned, the room temperature should be between 77 and 80.6 F. Let the body temperature drop slowly, so you will feel more comfortable. But if your extremities are cold and shivering violently, it means that you need warmth, so an extra blanket is needed.
If your limbs, hands and feet are warm and the whole body is sweating, it means that you need to dissipate heat and you can take off too much clothing.
Undo the clothes on the body, rub the body up and down with a towel with warm water (98.6 F), especially the large blood vessels such as the armpit and katydid fossa, so that the blood vessels of the skin can expand to dissipate the body heat, and the water vapor evaporates from the body surface.
Drink more water. To help sweat and prevent dehydration. Water has the function of regulating temperature, which can reduce body temperature and replenish water loss in the body.
How to measure body temperature correctly? You should avoid over-dressing or covering too much, as more heat is generated than lost, and the body temperature rises beyond normal. It is not advisable to measure body temperature after exercising, after bathing, or after drinking a lot of warm water.
