| Methods |
Single‐centre randomized controlled trial conducted in USA |
| Participants |
92 participants over the age of 18 years admitted to PACU with admission temperatures of 35°C or less. Participants were excluded if they had a planned admission to critical care, preoperative fever or sepsis, an open undressed burn, neurological problems with thermal instability, inability to co‐operate with rewarming interventions, continually tossed off covers or combativeness, or if they did not allow temperature assessment. 2 participants were inadvertently excluded from the study |
| Interventions |
Warmed cotton blanket (n = 31)
Radiant lights (n = 30)
Forced air warming blanket (n = 29) |
| Outcomes |
