84 A Proof-of-concept for a Continuous-temperature Circulating Water Bath in Frostbite Limb Rewarming
Bibliographic record
Abstract
Abstract Introduction Frostbite treatment is challenging due to tissue damage from ischemia and crystal formation. The American Burn Association advises rapid rewarming in 38-42°C water, yet hospital implementation is inconsistent. Our objective is to facilitate this step of frostbite treatment with a proof-of-concept, descriptive study of a proposed continuous-temperature circulating (CTC) water bath. We hypothesize that this design will effectively rewarm chilled extremities within the requisite 30 minutes without requiring frequent monitoring and adjustment of water temperature. Methods We constructed a CTC water bath system with a reservoir and a continuous warming and circulating device (CWCD). Water and tissue temperature were monitored using a needle probe thermometer. Pigs’ feet were chilled and immersed in 39.0 °C water with or without a CWCD. Results Without a CWCD, tissue warmed from 3.2 ± 0.3 °C to 34.2 ± 0.2 °C over 30 minutes, with a final water temperature of 36.5 ± 0.1 °C. With a CWCD, tissue warmed from 2.7 ± 0.2 °C to 36.7 ± 0.2 °C, with a final water temperature of 39.1 ± 0.1 °C. Conclusions This study demonstrates that the CTC water baths maintained at 39.0 °C offer a reliable and effective method for rewarming hypothermic tissue within 30 minutes. Continuous water temperature at 39.0 °C proved crucial in achieving euthermic tissue warming. These findings suggest that our approach could provide a practical solution to the inconsistent and impractical nature of current frostbite rewarming methods in clinical settings. The highest factor contributing to rewarming compliance is temperature regulation. These are mitigated by the CTC water bath. Further studies are ongoing to validate these findings in clinical practice and explore scalability and feasibility. Applicability of Research to Practice This research demonstrates the effective rewarming of chilled tissues using a CTC water bath. Future research will focus on developing a portable CTC water bath for implementation in acute care settings in the initial treatment of frostbite. This device may be utilized further in paramedic vehicles/stations and rural clinics where patients need long transport to the regional burn centers. Funding for the Study N/A

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
