Registered outcomes11
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Incidence of hypothermia on PACU arrival | Onf arrival in the PACU max up to 5 minutes from arrival | Proportion of patients with core temperature \< 36.0 °C measured by zero-heat-flux thermometry (3M SpotOn). Non-inferiority margin for the risk difference (resistive minus forced-air): 7.5 percentage points. |
| Secondary | Core temperature at end of surgery | At completion of skin closure up to 10 minutes from skin closure | Core temperature (°C) measured by zero-heat-flux thermometry (3M SpotOn). |
| Secondary | Postoperative shivering | From PACU arrival to PACU discharge, assessed every 15 minutes (up to 4 hours) | Incidence (BSAS \>= 1) and severity (highest Bedside Shivering Assessment Scale score, 0-3; higher score = more severe shivering). |
| Secondary | Thermal comfort | Once fully oriented in PACU (Aldrete score >= 9), up to 4 hours after arrival | Patient-rated 5-point Likert scale (1 = very cold, 2 = cold, 3 = comfortable, 4 = warm, 5 = too hot). |
| Secondary | Subjective feeling of cold | On PACU arrival (if able to respond) and when fully oriented in PACU (Aldrete score >= 9), up to 4 hours after arrival | Proportion of patients answering "yes" to the question "Do you feel cold?". |
| Secondary | Objective signs of thermal discomfort | On PACU arrival and when fully oriented in PACU (Aldrete score >= 9), up to 4 hours after arrival | Proportion of patients with at least one sign of cold discomfort assessed by a blinded observer (piloerection; cold, pale or mottled extremities; shivering; curling up or pulling blankets; request for blankets or warming). Signs of heat discomfort (sweating, flushing, uncovering) are recorded separately. |
| Secondary | Lowest intraoperative core temperature | From induction of anaesthesia to end of surgery (assessed during surgery) up to 4 hours from start of the surgery | Lowest core temperature (°C) recorded during surgery by zero-heat-flux thermometry. |
| Secondary | Incidence of intraoperative hypothermia | From induction of anaesthesia to end of surgery (assessed during surgery) maximum of 4 hours from start of the surgery | Proportion of patients with any core temperature \< 36.0 °C during surgery. |
| Secondary | Core temperature over time | From induction to end of surgery; PACU arrival, 30 minutes after arrival and PACU discharge (up to 4 hours) | Core temperature (°C) at 15-minute intervals during surgery and at predefined PACU time points. |
| Secondary | Length of PACU stay | From PACU arrival to discharge, up to 24 hours | Time from PACU arrival to PACU discharge (minutes). |
