Influence of polyester gauze on evaporation capacity and healing of the surface of microskin graft wound after escharectomy

摘要: Objective To investigate the influence of polyester gauze on evaporation capacity and its clinical effect after escharectomy deep burn wound micro-skin grafting. Methods Twenty patients with admitted within 24 hours injury underwent Meek skin Two surfaces area about 1% as whole surface were used, one covered by graft inner dressing (polyester group), other split-thickness sheet 0. 3 mm ×0. in size vaseline oil (vaseline group). Five days grafting, capacities dressing, without dressing( nude wound), normal near tested test equipment. The complete healing time survival rate both groups observed. degree pain during change was evaluated visual analog scale.

It is a relatively ideal cartier well new type cover for wound. Key words: Bums;  Skin grafting;  Bopcompatible materials ;  Wound
