blood blister formation on heel

  1. I'm a new nurse working in LTC.

    Can someone explain to me how a blood blister would form on a patient's heel?

    This resident is obese, sits in a wheel chair all day with her heels resting on the floor. Fluid is continually leaking from her legs, mostly it drips onto the floor but some of it runs down her legs. She has a history of open wounds on her calf and shin that are positive for MRSA.

    We've been using skin prep on her heels for months but the development of the blood blister is new. Its approximately 2.5 x 2.5 cm and being treated with skin prep until it opens.

    What caused the blood blister?

    Well, back track a little- you said her heels are resting on the floor alot of the time? I would say pressure/friction maybe? It sounds like she has alot working against her, perhaps flow issues in her legs, venous stasis? Lymphedema? I would find a way to keep the legs elevated to reduce the weeping, assess for compression wraps dependant on the wounds- they won't heal at all while they are weeping, and floating the heels to prevent further issues with pressure. The skin prep is great on the heels to prevent issues when sliding around in bed, but you still have to watch for pressure. Pillows, boots, (although I too work in LTC, I know sometimes the cost for the boots is often prohibitive in our world!) Do you have Broda chairs or Loungers that you can get the legs up? As far as the blister opening, my goal would be to hope it reabsorbs, then have the cap fall off later. But watch for infection!!! Especially if diabetic.
