Abstract:
OBJECTIVETo observe the effects of autologous fat granules in mixed grafting microskin grafts on repair of extensive deep burn wounds in patients.
METHODSTwenty patients hospitalized in our ward were enrolled for autogenous self-control test in wounds on both or symmetrical parts of wounds of the trunk, and they were randomly divided into experimental (E) trol (C) groups, the wounds in E group were repaired with autologous fat granules together with microskin in mixed grafting (volume ratio 1 : 1), and in C group only autologous microskin grafting was given. Wound healing rate was measured on 30th, 45th, and 60th day after operation. Wound specimens harvested for HE staining and PCNA immunohistochemistry examination on 7th, 14th, 21st, and after operation.
RESULTS(1) The mean wound healing rate on 30th, 45th, and 60th day after E group was (56.3 +/- 3.1)%, (76.4 +/-6.1)%, (96.2 +/- 1.5)%, which were respectively higher C group [(28.3 +/-2.0)%, (47.3 +/-4.8)%, (85.4 +/- 2.2)%, P < 0.01]. HE staining showed epithelization in E group was earlier than that in C group, with regular arrangement of collagen fibers. The quantity NA positive cells in E group were larger than that in C group, and PCNA was mainly expressed cells of basal layer .
CONCLUSIONAutologous fat granules in mixed grafting with autologous microskin promote wound healing.
