Just found out that our trauma surgeons are using blue dye on an occasional basis to detect GI perforations. For example wanting to do a one a time enteral feeding with methylene blue dye for a multiple gunshot wound patient.

Very aware of the 2003 FDA guidelines for methylene blue, however methylene blue is still available in Pharmacy.

UptoDate indicates methylene blue can be used to " identify sentinel lymph nodes"; and  "Dye studies may be useful for evaluating patients with a pleural effusion and a thoracostomy tube who are suspected to have an esophageal leak. Methylene blue introduced cautiously via a nasoesophageal tube will make or confirm the diagnosis by causing blue discoloration of the chest tube drainage. "

Welcome your perspective regarding one time administration of blue dye.

Hi Corilee,

To be clear methylene blue and the blue dye associated with worsening outcomes in sepsis are 2 different molecules. Methylene blue is not contraindicated and has even been used as an intravenous drug to treat septic shock in small randomized trials. Methylene blue acts as a selective iNOS inhibitor.

Cheers
