Clinical application and research of vacuum sealing drainage on wound of limbs trauma during emergency typeII operation

Objective To investigate the clinical application of treatment for operation of emergency extremities typeⅡwounds by vacuum sealing drainage(VSD).Methods Through retrospective study,thirty-eight patients were allocated in study group(n=38),in which patients were treated by VSD,and control group(n=18),in which patients were treated by normal drainage according to the traditional method.The indexes were investigated which included the infection rate in wound secretion,incidence of sepsis,the proportion of skin grafting operation,times of dressing change,wound healing time,grades of wound healing,post-operative hospitalization days and treatment total cost apart from the expend of built-in things.Results Times of dressing change,wound healing time and post-operative hospitalization days and treatment total cost apart from the expend of built-in things in group treated by VSD were significantly lower than that in control group(P0.05).The infection rate in wound secretion,incidence of sepsis was also lower than that in control group(P0.05),and the grades of wound healing was significantly higher in group treated by VSD as compared with that in control group(P0.05).Conclusions The emergency treatment of VSD can suck the exudate of the necrotic tissues and the wounds,maintain draining wounds and prevent infection.VSD can reduce the incidence of sepsis effectively,shorten the hospitalization time,and decrease the cost effectively.
