Asymptomatic Hypothermia

67 M originally came to the ED for worsening generalized weakness over the last week and SOB on exertion with his wife complaining of him being “slow to respond.”

VSS except temperature which was 89.9F rectally.

When asked if the patient was cold, he replied “not really.” No shivering noted.

Patient was placed on radiant warming blanket (bair hugger) and temp increased to 92.0 rectally after 2 hours. Pt reported feeling very hot during this temp recheck.

Hx includes a recent pacemaker placement for complete heart block 6 weeks ago, type 2 diabetes, HTN, chronic anemia, and chronic renal failure without the need for dialysis.

Chest X-ray and head CT negative.

WBC 4.1, Hgb 8.1, thyroid panel negative, other labs within expected findings for chronic issues.
