Reduction of Afterdrop by Using Active External Warming During Treatment of Accidental Hypothermia—A Randomized, Crossover Trial
Authors' conclusion
Adding active external warming reduces afterdrop compared with using only passive external warming measures in non-shivering individuals.
Study context
- Population
- Healthy volunteers with induced hypothermia (pharmacological inhibition of thermoregulation, −2°C ice tunnel, wet clothes, up to 2 h or oesophageal temperature 35°C)
- Participants
- 11 healthy volunteers
- Comparison
- Active external warming vs passive warming measures
- Primary endpoint
- Afterdrop (oesophageal temperature drop)
- Follow-up
- 10 min after end of rewarming phase
Methodological detailsfield study, experimental hypothermia
- Field study
- Experimental hypothermia
Primary result
As reported in the abstract
Afterdrop · 10 min after end of rewarming
Further findings
Temperature course
- Most had a small drop during wrapping, then a larger afterdrop walking out of the ice tunnel
