[Analysis of factors influencing healing time of burn wounds]

To analyze the factors influencing healing time, length of hospital stay and hospital costs in burn patients.

Seven hundred and ninety-one burn patients with principal component analysis were studied retrospectively.

There were some factors that influence healing time, including total area of burn, the area of full-thickness burn, the area of partial-thickness burn, inhalation injury, sepsis, shock, visceral complication, combined injuries, the size of surgical excision, the time of surgical excision, whether or not excision of burn wound was done in shock stage, and use of antibiotic, etc. Further analysis indicated that the patients undergo escharectomy during shock stage had better recovery with lower incidence of visceral complications and sepsis, especially in those with major burn over 30 percent TBSA.

To reduce healing time of burn patients, there are many effective methods such as the prevention and treatment of shock, sepsis, visceral complication, and appropriate use of antibiotics. The most important factor to reduce healing time of burn patients is escharectomy as early as possible for major burns.
