Abstract
Objectives: Our study aimed to explore the feasibility and effect of noninvasive and wireless intelligent monitoring of core body temperature in surgical patients, and to evaluate the effect of intraoperative hypothermia on rapid recovery index of the patients undergoing lung cancer surgery. Methods: From January 2020 to June 2020, a wireless temperature sensor was pasted onto the nonoperative side of the axilla preoperatively to monitor axillary temperatures to help estimate core temperature in lung cancer patients. The intraoperative body temperature changes and related factors were collected and analyzed. Independent associations between hypothermia exposure and the duration of hospitalization and direct medical costs were evaluated. Our research was carried out and report according to the STROBE guideline.Results: In total, 206 consecutive patients who underwent lung cancer surgery were recruited, and the incidence of hypothermia was 83.01%. The median proportion of patients experiencing hypothermia was 62.65%, with the largest decrease in temperature recorded as 1.034±0.569°C. The patients’ lowest body temperature was calculated as follows: (Y) = 35.423 - 0.003 × surgical duration + 0.045 × BMI - 0.012 × age, R2=0.182. Patients with hypothermia had longer hospital stays and higher medical costs (t=2.201, P=0.029 and t=5.048, P<0.001, respectively).Conclusions: Hypothermia contributes to extended hospital stays and increased medical costs for patients. The use of noninvasive and wireless intelligent monitoring throughout an operation and adoption of heat preservation measures are expected to prevent and reduce hypothermia and promote rapid patient recovery.
