Outcome Measures

Primary Outcomes (2)

  • Rewarming

    Assess if frostbitten extremities can be thawed in a warm water bath created by the experimental device.

    Up to 90 minutes

  • Time to Rewarm in Minutes

    Measure the time required to rewarm frostbitten extremities until the extremity is reddish or purple in coloration, and soft and pliable

    Up to 90 minutes

Secondary Outcomes (1)

  • Ease of Use: Provider Review

    Immediately after rewarming, up to 90 minutes

Study Arms (1)

Sous vide device

EXPERIMENTAL

The intervention will be the use of a sous vide device to heat the water bath to 38 degrees celsius, rather than the traditional methods of manual water exchanges or placing the frostbitten tissue under running water.

Device: Sous Vide Device (SVD)

Interventions

A basin will be filled to the marked line with water from jugs at room temperature, for each frozen extremity. The sous vide device (SVD) will be attached to the distal edge of the basin. The SVD will be turned on and set to maintain the bath at a constant 38 degrees celsius for 30 minutes duration. The thermometers will be powered on continuously and the researcher will record temperatures simultaneously from each thermometer and the SVD every 2 minutes. At the end of the 30 minute treatment, the extremity assessed by the researcher for warmth and pliability. If the extremity still feels cold or frozen, an additional 30 minutes in the water bath will commence, with subsequent reassessment. Rewarming will be considered complete when the affected tissue becomes red or purple, soft, and pliable.
