All

Inclusion criteria

Inclusion criteria: Patients undergoing primary total hip or knee replacement surgery

Exclusion criteria

Exclusion criteria: 1. Patients unable to provide informed consent (learning difficulties, cognitive impairment) 2. Patients with a higher likelihood of developing infection (rheumatoid arthritis or other inflammatory arthropathy; patients on immunosuppressive drugs) 3. Patients with unusually complex primary arthroplasty (likely to last > 1h 45 minutes) (infection rates are partly determined by the length of time the wound is open, as is the likelihood of cooling) 4. Patients with a history or family history of hyper pyrexia related to anaesthesia

Design outcomes

Primary

MeasureTime frame
Forehead temperature, measured using a temporal infra red thermometer at intervals during procedure (at start and every 15 minutes), at the time of arrival into the recovery ward and at the time of return to the elective surgery ward

Secondary

MeasureTime frame
Measured during stay in recovery ward on day of operation: 1. Postoperative pain, assessed by VAS as routinely administered at postoperative intervals 2. Recorded shivering 3. Blood loss, estimated by Hb drop across the operation 4. Days until mobile enough to go home
