Incidence and Severity of Hypothermia

Variable	Overall (n = 220)	Group GA (n = 34)	Group ISBPB (n = 186)	P value*
Hypothermia	27 (12.3)	10 (29.4)	17 (9.1)	0.002†
Mild (35.5–35.9℃)	25	8	17
Moderate (35.0–35.4℃)	2	2	0
Profound (< 35.0℃)	0	0	0

Values are presented as number of patients (%). GA: general anesthesia, ISBPB: interscalene brachial plexus block.

^*Logistic regression analysis adjusted with propensity score,

^†Statistical significance was found between perioperative hypothermia and anesthetic methods (GA vs. ISBPB; odd ratio: 0.172, 95% CI: 0.057, 0.517).
