Body temperature affects the success or failure of surgery!Anesthesiologists tell you the importance and key factors of “optimal body temperature”
The patient’s body temperature plays a vital role during surgery. Only by maintaining optimal body temperature can the success of the surgery be ensured and the speed of postoperative recovery be accelerated.
The two most important factors may affect wound healing and increase infection.
Su Xiang, Chief Secretary and Director of the Anesthesiology Department of Annan Hospital, pointed out that the two key factors that have the greatest impact on hypothermia are “slowing the metabolic rate” and “suppressing the immune response.” The former can lead to a decrease in the body’s ability to process drugs and anesthetics, which may delay recovery from anesthesia, thereby lengthening the patient’s time in the post-anesthesia care unit (PACU). In addition, it can impair the body’s ability to repair tissue and generate new cells, thereby affecting wound healing.
As for suppressing the immune response, patients will be more susceptible to infection, especially when foreign objects such as implants or surgical instruments enter the body, which increases the risk of infection. Chief Secretary Su Xiang added that hypothermia can also cause vasoconstriction, reduce blood flow to tissues, and further impair the immune response.
If the body temperature is too high or too low, it is not good to do this to maintain the normal range.
Chief Secretary Su Xiang shared that during the operation, the anesthesiology department will use various methods to avoid hypothermia, such as using thermal blankets, heated humidifiers in the breathing circuit, and heated intravenous infusions to maintain 36.5°C to 37.5°C ( A normal body temperature range of 97.7°F to 99.5°F) is critical to preventing these complications.
He emphasized that it is particularly important to strictly control normal body temperature during cardiac or neurosurgery, because the brain and heart tissue are highly sensitive to temperature changes, and even small deviations from the normal range may cause serious neurological deficits, arrhythmias, etc. Consequences; conversely, when the patient’s body temperature exceeds the normal range (the so-called “hyperthermia”), it can also be harmful during surgery.
Chief Secretary Su Xiang explained that high body temperature will increase the metabolic rate, leading to higher oxygen demand and potential tissue damage. It will also aggravate the inflammatory response, causing increased postoperative pain and delayed recovery. In addition, elevated body temperature may also lead to heat stroke or other heat-related complications.
