Fabrication and Characterization of Hybrid Sponge for Healing of Infectious Burn Wound.

Abstract

Burn is the fourth most common type of trauma worldwide. It often creates a third degree to fourth degree burn wound in the victims of accident. Hence a study was undertaken to fabricate hybrid sponge with biopolymers, silver nano particle and phytochemical constituents to accelerate wound healing. Antimicrobial susceptibility of wound isolates was evaluated by disc diffusion method. The silver nano particle was synthesized using the extracts of clove bud. The size of silver nano material ranged from 59-98 nm. The sponge was fabricated by freeze drying and its swelling property was evaluated. In the present study, 82.3% of the swelling of the sponge was observed within 20 minutes. The efficiency of sponge in healing infectious burn wound was assessed in rats. On the 20(th) day, 96.92% of wound was healed in sponge dressing and 58.2% in silverex treated rats. Thus, the study proved that the sponge accelerated the healing rate. Recent patents on the formulation of antimicrobial dressings and sponge have also been discussed in this paper.
