Hydrogel dressing containing recombinant human epidermal growth factor and preparation method and application thereof

The invention discloses a hydrogel dressing containing a recombinant human epidermal growth factor. The hydrogel dressing consists of 100 volume parts of mixed solution A and 2 to 8 volume parts of cross-linking agent; the mixed solution A is prepared by mixing 2.0 to 5.0 mass percent of polyvinyl alcohol aqueous solution and 0.5 to 2.0 mass percent of sodium alginate aqueous solution according to the mass ratio of (2-5): 1, and adding 0 to 0.1 mass percent of sodium benzoate, 5 to 20ug/g of recombinant human epidermal growth factor and 2.0 to 10 mass percent of glycerol; and the gel dressing is prepared by taking the 2 to 8 volume parts of cross-linking agent prepared by mixing sodium borate solution and calcium chloride solution, dripping the cross-linking agent into the 100 volume parts of mixed solution A, standing and defoaming to obtain the gel dressing. The dressing has good biocompatibility and mild and simple preparation condition, can be formed at room temperature, can effectively keep the activity
