[A comparative study on burn wound healing treated by different methods of recombinant human epidermal growth factor].

Objective: To explore an optimal method of recombinant human epidermal growth factor(rhEGF) application on the burn wounds of superficial II degree and profound II degree for accelerating its healing.
Methods: There were 180 burn wounds in 60 patients with the self-corresponding wound of the same degree as controls. The wounds of all patients were divided three regions(A, B, C). The wounds were treated once a day with 1% SD-Ag in region A as controls, with rhEGF(40 U/cm2) in region B, and with a combination of rhEGF(40 U/cm2) and Su Yu Ping (5 g) in region C. The wound healing time was recorded and compared.
Results: In regions A, B and C, the healing time of superficial II degree wound was (13.20 +/- 2.40) days, (10.20 +/- 2.20) days and (8.72 +/- 2.31) days (P < 0.01); that of profound II degree wound was (20.10 +/- 3.40) days, (17.20 +/- 3.12) days and (15.10 +/- 3.81) days respectively (P < 0.01, P < 0.05). The healed wound of profound II degree was elastic and tough in regions B and C, while that was not elastic and tough, and congestive in region A.
Conclusion: The above results indicate that rhEGF can enhance burn wound healing markedly and that a combination rhEGF and Su Yu Ping has more significant effect than rhEGF alone and is recommended for clinical application.
