OBJECTIVE: To investigate the effect of vacuum sealing(VS) technique and emergency internal fixation on the management of limbs open fracture and soft tissue dirty defects. METHODS: Fourteen patients (18 limbs) with open fracture and soft tissue dirty defects were treated by the VS technique and internal fixation after debridement and 14 patients managed by traditional method as control group. Wound surface were covered with polyvinyl alcohol foams with embedded drainage tubes connected with vacuum bottle (negative pressure of 50 to 60 kPa) after wound surface were debrided and fracture were fixed. Wound closure was performed with secondary suturing, or free flap, or loco-regional flap and mesh-grafts after 5 to 7 days. RESULTS: All wound surface healed completely. No complications (systemic and local) were found. After 4-6 months follow-up on average, the fracture healed well. There was significant difference in time of treatment, total cost of treatment and complication rate between 2 groups (P lt; 0.01). CONCLUSION: The VS procedure can drain the wound surface completely, decrease infection rate and stimulate the proliferation of granulation tissue. A combination of VS with emergency internal fixation is a simple and effective method in treatment of limbs open fracture and soft tissue dirty defects.
OBJECTIVE: To investigate the clinical effect of vacuum sealing in treatment of traumatic soft tissue defect. METHODS: From 1998. 8 to 2001. 2, 49 patients with 55 traumatic soft tissue defects were treated by vacuum sealing after debridement. Among them, there were 39 males and 10 females with mean age 38. 4 years. The wound area varied from 10 cm x 10 cm to 30 cm x 30 cm. In the experimental group, the wound surfaces or cavities were filled with polyvinyl alcohol foams with embedded drainage tubes connected with vacuum bottle (negative pressure of 50-60 kPa). Wound closure was performed with secondary suturing, or skin transplantation, or local flap grafting after 5-7 days. Besides, 126 patients were managed by traditional dressing as the control group. RESULTS: Out of 51 traumatic soft tissue defects (45 patients), the wound closure was performed with a free flap in 4, with local flap in 8, with skin grafting in 27, with secondary suturing in 6, and with vacuum sealing directly in the other 6 defects. Forty-five patients recovered and no complications (systemic and located) occurred. There were significant differences in time of secondary suturing, times of dressing, wound shrink and total therapeutic cost between two groups (P lt; 0.01). CONCLUSION: Vacuum sealing can protect the wound against contamination, evacuate the wound exudates completely, stimulate the growth of granulation tissue, and facilitate the wound healing; so vacuum sealing is a simple and effective method in treatment of traumatic soft tissue defect.
