“…It is known that as the ASA physical condition score increases, the perioperative hypothermia risk increases. It was reported in literature that one of the important risk factors is high ASA score 19 . Our experiments are consistent with previous findings in the literature, we found that the risk of developing perioperative hypothermia increased as the ASA score increased; ASA III patients had significantly higher hypothermia incidence.…”

Background Unintended perioperative hypothermia, defined as core body temperature less than 36°C, is closely related to many complications such as cardiovascular diseases, peroperative hemorrhagic diathesis and impairment of drug metabolism. Determination of the incidence of perioperative hypothermia and examination of risk factors may help to prevent hypothermia and its complications. Methods We conducted a prospective, observational study of 2015 patients who underwent various operations under general anesthesia, and the risk factors of developing hypothermia were analysed. Results The incidence of perioperative hypothermia was 78.6%. The incidence of hypothermia within 2 hours was 56.6%, and after 2 hours, it was 100%. Mean age was 49.36 ± 16.10, and 17.8% were over 65 years old. The mean body mass index (BMI) was 27.96 ± 3.94 kg/m2; 60.8% of the patients had American Society of Anesthesiologists (ASA) I score, 33.4% had ASA II and 5.8% had ASA III; 35.8% of the patients had co‐morbidities. Intravenous and irrigation fluids were unwarmed; 99.9% of the patients were warmed passively, and only 0.1% of patients received active heating intraoperatively. The incidence of hypothermia was higher in overweight (BMI ≥ 25 kg/m2), elderly (>65 years) patients and those with co‐morbidities. High American Society of Anesthesiologists (ASA) scores, grade 3‐4 surgery, endoscopic surgery, duration of anesthesia >2 hours, infusion or irrigation >1000 mL significantly increased the incidence of hypothermia. Conclusion The incidence of perioperative hypothermia found was high. Important risk factors were found as prolonged duration of anesthesia and surgery, advanced age, overweight, high ASA scores, major surgeries, endoscopic operations and unwarmed fluid administration. High incidence may be reduced by raising awareness, considering fossible risk factors and following the recommendations of the guidelines on prevention of perioperative hypothermia.

“…Using the general linear model, P-value of 0.01 was obtained when males were compared to females reflecting greater susceptibility for hypothermia (Table 4 ). Sagiroglu et al identified male sex as a risk factor for perioperative temperature loss during major abdominal surgeries [ 16 ]. Similar results were found by Panagiotis et al who reported the length of stay in PACU of male patients longer than females due to postoperative hypothermia [ 17 ].…”

Introduction Mild hypothermia is common after general anesthesia. It is associated with discomfort and shivering. Greater fall of temperature is associated with more devastating complications. Data regarding the effect of gender on perioperative hypothermia is scanty. Objectives of the study To determine and compare mean core temperature loss in males and females undergoing laparoscopic cholecystectomy under general anesthesia. Setting and design Descriptive cross-sectional study in a tertiary care teaching hospital. Subjects and methods Ninety-seven elective laparoscopy patients were included through non-probability consecutive sampling. Intraoperatively, there was standardization of monitoring equipment, drapes, operation room temperature (21-22 °C), humidity (50%), irrigation fluid temperature (37 °C), peritoneal CO 2 temperature (21-22 °C), anesthetic fresh gas flow rates at induction and maintenance. Temperature recording equipment (nasopharyngeal probe) and temperature recording interval (10 minutes) were also standardized from induction till the end of surgery. Final temperature was recorded at the end of surgery before emergence. Results Mean temperature loss was 0.73 ⁰C ± 0.47⁰C. Mean loss was significant in males compared to females with a mean difference of 0.28°C ± 0.93⁰C; P-value= 0.003. Conclusion Mean temperature decreases significantly in laparoscopic cholecystectomy patients under general anesthesia. We recommend that more care is needed to prevent hypothermia in male patients because of their higher susceptibility to hypothermia.

BACKGROUND: Unintended Perioperative Hypothermia (UPH) is defined as a core body temperature less than 36°C. The Turkish Society of Anesthesiology and Reanimation [Türk Anesteziyoloji ve Reanimasyon Derneği (TARD)] published a "Guideline for the Prevention of the Unintended Perioperative Hypothermia" in 2013. This study aims to decrease the incidence of unintended UPH in our hospital using a protocol, which is prepared according to the recommendations in the Guideline for the prevention of unintended perioperative hypothermia. METHODS: A prospective quality improvement study was conducted with the protocol, which was prepared to decrease the incidence of unintended perioperative hypothermia in patients undergoing surgery. We measured and compared the perioperative hypothermia incidence before the implementation (
