Acute Tissue Necrosis

I have been collecting data on, and investigating incidents of unexplained, postoperative lesions, acute tissue necrosis. Many of these have been confused with electyrosurgical burns, but in depth investigation has shown other causes, primarily due to pressure or shear forces.
These lesions usually occur at the buttocks, heels, occiput, etc.

In investigating over 200 such incidents, and comparing data from other sources, the common denominators are:

  • * surgical procedures lasting over 2 hours.
  • * lesion is not noticed immediately following surgery, but develops several hours to 48 hours post op.
  • * cv surgery
  • * no electrosurgical incidents during surgery

As we gain more experience in this area, we are now getting reports of some unexplained lesions that are not in “pressure” areas, but also do not fit the criteria of electrosurgical burns.

We are conducting research to see if there are possible drug interactions, and other variables which may have causative factors.

I was wondering if the surgeons have had any experiences they would like to share with me and members of the list.

This information is not for public dissemination, and is used to assist hospitals and surgeons in identifying actiual causes of unexplained postoperative lesions and acute tissue necrosis.
