Abstract:
Objective: To explore the preventive efficacy of local injection of hyaluronidase and topical administration of Hirudoid cream against skin damage caused by vinorelbine extravasation in rats. Methods: Vinorelbine was iv infused into the hinder limbs of SD rats to establish the extravasation model. The 48 rats were randomly divided into 6 groups. The model group received no treatment. The other five groups were given local injection of hyaluronidase, topical administration of Hirudoid cream, local injection of hyaluronidase plus topical administration of Hirudoid cream, local injection of normal saline (NS), or topical administration of normal saline, respectively. The lesion area and the healing time were observed and recorded on d 1, d 4, d 8, d 12, d 18, d 24, and d 30. Results: The lesions were cured by local injection of hyaluronidase on d 30. The lesion area were significantly reduced in hyaluronidase group compared with that in topical Hirudoid cream group, combined therapy group, local NS injection group, topical NS administration group, and the model group on d 1, d 4, d 8, d 12, d 18 and d 24 (P < 0.05). The healing time was significantly shorter in hyaluronidase group than that in other 5 groups [(21.9 ± 3.0) d vs (28.8 ± 3.5) d, (28.0 ± 2.9) d, (28.6 ± 4.1) d, (29.8 ± 2.6) d, and (30. 6 ± 3.0) d, P < 0.01]. Conclusion: Local injection of hyaluronidase is effective for skin damage caused by vinorelbine extravasation, but topical administration of Hirudoid cream is ineffective and combined therapy can not further improve the efficacy of hyaluronidase monotherapy.
