Genel anestezi altinda opere edilen hastalarda i̇stemdişi perioperatif hipotermi i̇nsidansi ve risk faktörlerinin i̇rdelenmesi

Unintended perioperative hypothermia, defined as a core body temperature less than 36°C, occurs between the preoperative period and the postoperative period. It is closely related to many complications such as cardiovascular diseases, peroperative hemorrhagic diathesis, impairment of drug metabolism. Determination of the incidence of perioperative hypothermia and examination of risk factors may help preventing the hypothermia and its complications. In our study, we determined the incidence of unintended perioperative hypothermia in patients undergoing general anesthesia and examined risk factors. 2015 patients were studied and the incidence of perioperative hypothermia was 78.6%. There was a statistically significant difference between the patients with and without hypothermia in terms of age and age group, body mass index (BMI), ASA classification and chronic disease status (p <0,05). The age and BMI of hypothermic patients were significantly higher than those without hypothermia. Patients with hypothermia who were older than 65 years, those with a BMI greater than 25 kg / m2 and any chronic disease were significantly higher than those without hypothermia. Patients with ASA-I had a significantly lower percentage of hypothermic patients. Percentage of those with grade 3 or 4 surgery, patients with endoscopic surgery, duration of anesthesia over 2 hours, infusion or irrigation amount greater than 1000 ml were significantly higher than those without hypothermia. We think that this high incidence can be reduced by raising awareness about unintended perioperative hypothermia, cooperating with the surgical team, training in the use of appropriate and effective heating methods, increasing the rates of intraoperative active heating and considering the recommendations of the guidelines on prevention of perioperative hypothermia.
