Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention 1: Participants will be warmed preoperatively for 45 minutes using a forced air warming device (brand name 'Bair Hugger') set at 43 degrees Celsius high fan. A lower body warming blanket will be applied over 50% of the anterior body surface. Irrigation fluids (used to irrigate the surgical site) will be warmed in a thermostatically controlled cabinet to a temperature of 38–40°C.

Intervention 2: Participants irrigation fluids (used to irrigate the surgical site) will be warmed in a thermostatically controlled cabinet to a temperature of 38–40°C.

Intervention 3: Participants will be warmed preoperatively for 45 minutes using a forced air warming device (brand name 'Bair Hugger') set at 43 degrees Celsius high fan. A lower body warming blanket will be applied over 50% of the anterior body surface.

Comparator / control treatment
Participants will receive ‘usual care’. This does not include preoperative warming or the use of warmed irrigation fluids. Both intervention and control groups will receive active intra-operative warming, as is the current routine practice.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be assessed for inclusion in the study and consented by a researcher not involved in administering the interventions or collecting outcome data. A researcher (off site) not involved in the patient recruitment process will be contacted by SMS to reveal treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A researcher not involved in the study will generate a stratified block random sequence using a randomization computer program.
Masking / blinding
Blinded (masking used)
