Abstract:
Objective To compare the efficacies of intralesional hyaluronidase(HAase), intralesional dexamethasone(DEX), and intralesional HAase plus intralesional DEX on skin damage caused by vinorelbine extravasation in a rat model. Methods After establishing an animal model with vinorelbine extravasation in each lower extremity of 40 Sprague-Dawley rats, we treated the rats with intralesional HAase,intralesional DEX, intralesional HAase plus intralesional DEX,intralesional saline,or received no treatment as control.The wound area on 1 d, 4 d, 8 d, 12 d, 18 d, 24 d, 30 d and the time of healing were observed and compared.Results The wound area on 1 d, 4 d, 8 d, 12 d, 18 d and 24 d was significantly lower in intralesional HAase group, intralesional DEX group,intralesional HAase plus intralesional DEX group,and intralesional saline group than that in control group (P ＜0.05), and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P ＜0.05). The healing time was significantly shorter in 4 therapy groups than that in control group [(25.1±3.1) d, (27.9±2.8) d, (23.0±3.2) d, and (28.4±3.9) d vs.(31.2±3.0) d, P ＜0.05], and that was significantly lower in intralesional HAase group and intralesional HAase plus intralesional DEX group than that in intralesional DEX group and intralesional saline group (P ＜0.05). Conclusion The monotherapy with intralesional HAase or intralesional DEX, with decreasing the extent of skin damage and shortening the healing time, is effective therapy for skin damage caused by vinorelbine extravasation, and the monotherapy with intralesional Haase is more efficacious. The efficacy of intralesional HAase plus intralesional DEX seems better than that of monotherapy.
