Objective:To investigate the curative effect of vacuum sealing drainage(VSD)in children with infected wounds.Methods:From July 2008 to March 2010

15 children with infected wounds were treated

including earthquake damage in 3 cases

traffic accident in 10 cases

and heavy crush injury in 2 cases.All the 15 patients with injuries had 35 wounds in the lower limbs;the wounds had varying degrees of skin and soft tissue necrosis

with 11 cases of tendon exposure

7 cases of bone exposure

2 cases with bone compartment syndrome

and 10 cases of fracture fixation.After the debridement

the VSD material covered the wound to maintain the pressure at the 0.04 MPa

and kept continuous drainage 7~10 d.Results:Except for one child who gave up

all the wounds were narrowed obviously;granulation tissue grew well.In wound repair using skin grafts(13 patients)or flap(1 patient)graft

skin graft and flap graft were the first stage healing.The shape

texture

and color showed no difference compared with other traditional methods.Conclusion:For the VSD treatment of children with infected wounds

the culture of granulation tissue needs about 10 days to 20 days

while the traditional method needs about 1 to 2 months before the autolysis and necrotic skin off and replacement of the dressing.Therefore

the VSD treatment can significantly shorten the course

reduce the psychological burden of children and economic burden of their families

effectively control the wound infection

promote the growth of granulation tissue

and thus obtain a significant therapeutic effect.
