Mind you, we're a tele/med-surg unit, but we have standing orders for patients who might go into DTs. We use a CIWA scale to assess their level. Detoxing patients can die without the proper treatment. I'm surprised that this patient was not treated medically.
We usually give a Banana bag daily (with things like thiamine and folic acid in it), librium, and valium. Pt is assessed q2h neuro and vitals and graded according to the CIWA scale. If the patient scores high (I think above a 7) they have to be sent to ICU:
