Effect of nano-silver hydrogel coating film on deep partial thickness scald model of rabbit

الملخص EN

Objective : Observing the effect of nano-silver hydrogel coating film on deep partial thickness scald model of rabbit.

Method : We prepared boiling water scalded rabbits with deep II degree scald models and applied high, medium and low doses of nano-silver hydrogel coating film for different time and area.

Then we compared the difference of burned paper weight before administration and after administration model burns, burn local skin irritation points infection, skin crusting and scabs from the time, and the impact of local skin tissue morphology.

Result: Rabbits deep II degree burn model successful modeling; on day 12, 18, high, medium and low doses of nano-silver hydrogel coating film significantly reduced skin irritation of rabbits infected with the integral value (P < 0.01, P < 0.05) ; high, medium and low doses of nano-silver hydrogel coating film group significantly decreased skin irritation, infection integral value (P < 0.01, P < 0.05); high, medium and low doses of nano-silver hydrogel coating film significantly reduced film rabbits’ scalded skin crusting time (P < 0.01), significantly shortened the rabbit skin burns from the scab time (P < 0.01), and significantly improved the treatment of skin diseases in rabbits scald model change (P < 0.01, P < 0.05).

Conclusion : The nano-silver hydrogel coating film on the deep partial thickness burns has a significant therapeutic effect; external use has a significant role in wound healing.
