A comparison of Orve+ Wrap and forced air warming blankets in managing patients’ temperature following surgery

INTERVENTION: Participants are randomised to one of two groups electronically using sealed envelope™ (London, UK) on a 1:1 basis with stratification for Spinal and general anaesthesia and for age under 65 years or 65 years or greater. Control arm: Patients will receive Forced Air Warming at the highest setting deemed clinical suitable. Group 2: Patients will receive Orve+ Wrap for the duration of their Post Anaesthetic Care Unit stay or until the patient reaches normothermia (36.5°c) beforehand. Patients in both groups will be followed up until hospital discharge CONDITION: Specialty: Anaesthesia, perioperative medicine and pain management, Primary sub‐specialty: Anaesthesia, Perioperative Medicine and Pain Management; UKCRC code/ Disease: Injuries and Accidents/ Complications of surgical and medical care, not elsewhere classified ; Signs and Symptoms ; Hypothermia post‐surgery PRIMARY OUTCOME: Mean temperature difference at 60 minutes post PACU admission using the zero heat flux thermometry Spot On (3m, Bracknell, UK). SECONDARY OUTCOME: No secondary outcome measures INCLUSION CRITERIA: 1. Patients aged >18 2. Planned elective or expedited orthopeadic surgery 3. Able to provide informed consent
