Abstract

Abstract:

BACKGROUND: In recent years, vacuum sealing drainage technology has been widely used in the treatment of orthopedic wounds or to facilitate skin graft survival, both of which have achieved good results.
OBJECTIVE: To observe the curative effects of vacuum sealing drainage technology in the wound healing after limb open fractures, soft tissue defects, pressure sores, and chronic osteomyelitis.
METHODS: Fifty-four patients of fractures combined with soft tissue defects, postoperative exposed bone, osteomyelitis, a large area of pressure ulcers or severe infections, selected from the 273rd Hospital of PLA, were randomly divided into test and control groups according to the wishes of patients. The test group included 36 patients who were treated with vacuum sealing drainage using polyethylene ethanol hydration seaweed salt after debridement, and the control group included 18 patients who were treated with conventional dressing. Wound cleaning time, number of dressings, and wound healing time were detected and compared in the two groups.
RESULTS AND CONCLUSION: Compared with the control group, the wound cleaning time and wound healing time were shorter in the test group, and the number of dressings was also decreased in the test group (P < 0.05). After removal of sponge dressings, in the test group, wound granulation was fresh and grew obviously with no exudates after the necrotic residue was removed and vacuum sealing drainage was changed. For the bone exposure patients, the wound area was reduced, or even there was no exposed bone any more. After skin grafting, vacuum suction and pressure due to vacuum sealing drainage technology made all skin grafts survive. In the patients with chronic osteomyelitis, the exudates were gradually reduced until disappeared after vacuum sealing drainage was exchanged three or four times, and pathogens were not found in bacterial culture. After combined treatment of debridement and vacuum sealing drainage, there were many fresh granulations in the patients with large areas of pressure sores; after replacement of vacuum sealing drainage several times, the granulation grew to the same height with the surrounding skin.
