543 Escharotomy Incisions in the Burn Foot and Toe with Compartment Syndrome

Abstract Introduction Patients with burn injuries are at risk for lower extremity compartment syndrome, especially if the injury is circumferential. The hypothesis was that two dorsal escharotomy incisions to release foot and toe compartment syndrome would be most efficacious in the prevention of lower extremity amputations. Methods This was a retrospective chart review of foot compartment syndrome in burn patients between January 2001 and May 2019. Results The study consisted of 59 feet from 32 patients who had been admitted to the Burn Center for thermal injury. The patient age was a mean±sd of 29±30 years, and 41±29 as the % total body surface area (%TBSA); there were 19 males and 13 females. All patients had received fluid resuscitation on admission. Twenty-one (66%) of the patients did not require amputations after undergoing a median of two incisions (range 1–5); 6 of 59 (11%) required fasciotomies. Compared to medial or dorsal or multiple echarotomies, the majority of patients who underwent two dorsal foot escharotomies did not require amputations, p = .0001. Significantly more patients were alive with no amputation 15 (50%) compared to 4 (13%) (dead with amputations), p = .02. Survivors were significantly younger than the non-survivors (median 20 and range1-69) compared to the non-survivors (48, 12–59), p =.04. The survivors also had significantly less severe %TBSA median 22 (range 2–75) versus 83 (35–95) %TBSA, p < .0002. Dorsal/Lateral incisions had the highest number of amputations. Conclusions Foot dorsal compartment release is the most effective site for escharotomies in the treatment of burn-induced compartment syndrome. It does not require more than two incisions at the skin/fat level and over the second and fourth metatarsal bones on the dorsal part of the foot to decrease the lower extremity amputation rate in the majority of cases.
