ABSTRACT

Hypothermia is a condition in which the body becomes cold because the body temperature regulation is not able to overcome / regulate body temperature into normal level. Secondary hypothermia can occur due to medical actions such as drugs given in general anesthesia. Approximately 60% of postoperative patients who enter the Recovery Room can become hypothermic. The purpose of this study was to determine the relationship between age, duration of surgery, and use of inhalation agents with the incidence of hypothermia in postoperative patients with general anesthesia in the recovery room at the Central Surgical Installation of Kanjuruhan Hospital. Kepanjen. Cross sectional research method was used, The sample used was 80 people with simple random sampling. Patients temperature were measured before entering the operating room, and measured later after the surgery. Age, duration of surgery and use of inhalation were obtained from the patient's pre-postoperative data. Results: There was a significant effect (p<0.01) between age, and use of inhalation agents with the incidence of hypothermia in postoperative patients with general anesthesia in the recovery room at the Central Surgical Installation of Kanjuruhan Kepanjen Hospital. Age makes thermoregulation in patients different. Elderly experience changes in the function of the respiratory muscles, heart and blood vessels so that thermoregulation becomes less effective. Meanwhile, inhalation agents make blood vessels expand or vasodilate so that the body loses heat more easily. The hypothalamus and thermoregulatory control are also impaired by these inhaled agents. This makes the patient more susceptible to hypothermia.
