The authors are fro Standord University, the VA Palo Alto Health Care System and the University of Arkansas for Medical Sciences.


Patient selection: orthopedic surgery

 

Outcome: postoperative hypothermia (< 36.0 °C)

 

Risk factors for postoperative hypothermia:

(1) intraoperative hypotherrmia (odds ratio 2.7)

(2) low body mass index (BMI; odds ratio 1.06 per kg per square meter)

(3) older age (odds ratio 1.02 per year; age > 85 years)

(4) adult reconstruction (odds ratio 4.1)

(5) hip and pelvis procedures such as hip fracture (odds ratio 8.8)

 

where:

• The mean BMI was 27.9 kg per square meter.

 

Additional risk factors:
