Impact of modified vacuum sealing drainage on local blisters / 中华创伤骨科杂志

ABSTRACT

Objective To explore the impact of modified vacuum sealing drainage (VSD) on prevention of tension blisters during treatment of opening fracture wounds.Methods From March 2015 to February 2016,53 patients with 60 open fracture wounds were treated after surgery by VSD at our department.They were 28 males (33 wounds) and 25 females (27 wounds),aged from 24 to 65 years (average,41.1 years).The patients were divided into 2 groups.Group A (33 wounds) were subjected to traditional VSD after surgery while group B (27 wounds) to modified VSD.The mean time from injury to surgery was 5.2 hours (from 2.0 to 8.3 hours).The VSD dressing was first removed to observe whether any tension blisters would appear surrounding the dressing 5 days after surgery.Results Tension blisters appeared around 9 wounds in group A (with an incidence of 27.3％) but around one wound in group B (with an incidence of 3.7％).The difference between the 2 groups was statistically significant (P =0.037).Conclusion In treatment of open fracture wounds,the modified VSD can effectively prevent formation of tension blisters surrounding the dressing while it is used to cover a wound.
