Abstract:
Objective To evaluate the wound healing efficacy of negative pressure wound therapy (NPWT) combined with topical oxygen therapy ( TOT ) on the traumatic chronic wounds , and to explore new conception and method for traumatic chronic wounds . Methods Sixty-four patients with traumatic chronic wounds were randomized into two groups ( n=32 ) .Patients in the control group were treated by NPWT , and those in the intervention group were treated by NPWT and NPWT with TOT 3L/min.The treatment time lasted 12 days, and the dressing and tubes were changed every three days in the two groups .After 12 days, all the pa-tients were treated by standard moist therapy or surgery until healing or three months .Indicators of observation: The pressure ulcer scale for healing (PUSH) scores and granulation covered rate at 0, 3, 6, 9, and 12 days were measured, and healing rate and healing time during three months were calculated in the two groups . Results The PUSH scores were declined with intervention time during 12 days in the two groups , indicating the treatment was effective , but there was no significant difference between the two groups ( P>0 .05 ) .The granulation covered rate was increased with intervention time , and the granulation covered rate was higher in the intervention group than in the control group(P<0.001).The healing rate was higher in the intervention group than in the control group (87.50%vs 59.38%, P<0.05 ).The healing time of 14 days was shortened in the intervention group compared with the control group (P<0.001). Conclusion NPWT combined with TOT is an effective and feasible method for complicated traumatic chronic wounds , which can en-hance granulation growth , rise healing rate and shorten healing time .
