Summary
Major surgery and blood transfusions significantly increase the risk of mild intraoperative hypothermia (MIH) in surgical patients. These factors are key predictors for developing MIH during procedures.
Area of Science:
- Anesthesiology
- Surgical Patient Safety
Background:
- Mild intraoperative hypothermia (MIH) is a common complication during surgery.
- Identifying risk factors for MIH is crucial for improving patient outcomes.
Purpose of the Study:
- To investigate the influence of various patient and surgical factors on the occurrence of MIH.
- To determine the predictive value of age, surgery duration, room temperature, surgery type, blood transfusion, gender, and anesthesia on MIH development.
Main Methods:
- Prospective observational study of 130 patients undergoing surgery.
- Data collected on patient demographics, surgical variables, and anesthetic techniques.
- Logistic regression analysis with backward elimination used to identify risk factors for MIH.
Main Results:
- 41% of patients developed mild intraoperative hypothermia.
- Major surgery (Odds Ratio 2.8) and blood transfusion (Odds Ratio 6.7) were identified as significant risk factors for MIH.
- Other investigated factors like age, surgery time, room temperature, gender, and anesthetic method did not show a significant impact.
Conclusions:
- Major surgery and the need for blood transfusion are independent risk factors for developing mild intraoperative hypothermia.
- Anesthesiologists and surgical teams should be vigilant for MIH in patients undergoing major procedures or requiring blood transfusions.
