The use of esmarch exsanguination for the treatment of extremity wound burns.

Tourniquets are routinely used during the excising and grafting of burn wounds located on the limbs in order to decrease blood loss. It has been postulated that the exsanguination of extremities by using Esmarch bandages might further reduce blood loss. However, there are concerns about a decrease in graft quality when Esmarch bandages are applied. The purpose of this prospective, double-blinded randomized study was to compare Esmarch application in addition to tourniquet (exsanguinated extremities) with the application of tourniquet alone. Thirty-eight excisions of bilateral extremity wounds were performed. Both limbs were tangentially excised after tourniquet application with one limb randomly chosen for prior Esmarch exsanguination. Blood loss was estimated during this procedure. Graft take was assessed twice: on post-operative days 3 and 7. The burn surface area and total area grafted were equivalent in the extremities with Esmarch bandages when compared to the extremities without them. Total blood loss was less in the extremities where Esmarch was applied. Graft take was similar in the two groups. Statistical analysis was performed with a two-tailed paired T-test. It is concluded that the use of Esmarch exsanguination in addition to tourniquet further reduces blood loss without affecting the quality of the engraftment.
