Abstract:
Objective To study the effect of different negative pressure values of negative pressure wound therapy (NPWT) effect on skin graft .Methods Eighty patients were selected ,who underwent chronic wound bed and preparedto treat with skin graft in surgical ward of emergency department in the Second Affiliated Hospital of Chongqing Medical University from January 2012 to July 2012 .Eighty patients were divided into 8 groups ,group A were treated with packing pressure after skin graft ,group B~ H were treated with continuous NPWT ,pressures were -10 ,-20 ,-30 ,-40 ,-50 ,-60 and -70 kPa ,respectively .Whether they were in comfortable situation at second day after surgery were observed .Flap survival area at Seventh day after surgery was meas‐ured .Results The patient comfort ,flap survival area ,wound healing time of group B to H were higher than those of group A (P<0 .05) .Patient comfort tended to decrease with the increasing negative pressure values between -10 - -40 kPa(P<0 .05) .Flap survival area ,healing time of group B ,C were higher than those of group D to F(P<0 .05) .Conclusion Application of NPWT technology in wound ,-10 kPa negative pressure value can not only improve wound blood circulation ,but also ensure patient be comfortable .
