Can a simple air warmer save lives in the field? tiny pilot study aims to find out.
NCT ID NCT07450092
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether a forced air warming device can be used by emergency responders to rewarm people who have become dangerously cold (accidental hypothermia) before they get to a hospital. Only 4 healthy volunteers will take part to see if the procedure is practical and works as expected. The study does not involve actual hypothermic patients, so it is a first step to see if the idea is worth testing further.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Forced air warming device
- What this could lead to
- If successful, this could show that forced air warming is a practical way to start rewarming hypothermic patients before they reach the hospital.
- What could go wrong
- This is a very small pilot study with only 4 healthy volunteers, not real patients. It only tests feasibility, not effectiveness, and may not translate to real-world emergency settings.

Inclusion Criteria: * Age: Participant must be over 18 and under 45 years of age at the time of signing the informed consent. * Type of Participant and Disease Characteristics: Participants who are overtly healthy as determined by their medical history. The participants will be asked to fill out a health report stating to be healthy, using no relevant medication, and having no relevant allergies or hypersensitivity to the active substances or to any of the excipients of the medications used. * Weight: BMI under 30 kg/m2 * Sex and Contraceptive/Barrier Requirements: Both male and female participants can be included. Female participants of childbearing potential will be asked to take a pregnancy test to confirm the absence of pregnancy prior to study drug administration on both visit 1 and 2. * Informed Consent: Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Exclusion Criteria: * Drugs: Concomitant use of sedatives, MAO-inhibitors, SSRI, ritonavir, cimetidine, chlorpromazine, phenytoin, erythromycin, itraconazole, platelet inhibitors, Apomorphine, alcohol (during the trial period) or other opioids or opioid antagonists (during the trial period). * History of drug dependency: Recent head injury (last. 12 months), known increased ICP, seizures or epilepsy * Other: Known reduced liver- or kidney function, reduced respiratory drive, known supraventricular tachycardia or prolonged QTc, hypertrophy of the prostate or urinary constriction, ongoing pregnancy or breastfeeding. Known acute glaucoma, myasthenia gravis. History of cold injuries or frostbites.
