负压封闭引流(VSD)技术在NPUAP 3、4期压力性损伤患者中的应用及护理

目的探讨负压封闭引流(vacuum sealing drainage,VSD)技术对国际压疮防治顾问学会(national pressure ul-cer advisory painel,NPUAP)3、4期压力性损伤患者的持效及护理体会。方法选取2017年1月一2018年12月大连大学附属中山医院收治的14例NPUAP 3、4期压力性损伤患者,住院后创面行坏死组织清创术,术后采用VSD对创面进行封闭引流,同时给予抗感染、营养、对症、支持等治疗及护理。结果3、4期压力性损伤患者在VSD治疗后的创面面积为(39.11±9.57)cm^2,较治疗前的(137.9±32.24)cm^2明显缩小,差异有统计学意义(P=0.0036)。VSD还能够显著促进创面肉芽组织的生长,刺激毛细血管增生,加快创面愈合速度。结论采用VSD治疗3、4期压力性损伤可显著缩小创面,促使创面血管再生,加快肉芽姐织生长,促进创面愈合,临床疗效明显,值得临床大力推广应用。

Application and nursing of vacuum sealing drainage(VSD)in patients with stage 3 and 4 pressure injury of NPUAP

Objective To explore the efficacy and nursing experience of vacuum sealing drainage(VSD)in.pressure in jury patients with stage 3,4 four of National Pressure Ulcer Advisory Panel(NPUAP).Methods A total of 14 patients with stage 3,4 pressure injuiy of NPUAP in Affiliated Zhongshan Hospital of Dalian University from January 2017 to December 2018 were selected.After hospitalization,debridement of wound necrotic tissue was performed,then VSD was used to seal and drain the wound after operation,and anti-infection,nutrition,symptomatic treatment and support were also done.Results After VSD treatment,the wound area of patients with stage 3,4 pressure injury was(39.11±9.57)m^2,which was significantly smaller than that before treatment of(137.9±32.24)m^2,the difference was statistically significant(P=0.0036).VSD could also significantly promote the growth of wound granulation tissue,stimulated capil lary proliferation,and accelerated the speed of wound healing.Conclusion VSD could significantly reduce the wound surface,promote wound angiogenesis,accelerate the growth of granulation tissue,and promote wound healing in the treatment of patient with stage 3,4 pressure injury.Its clinical effect is obvious,which is worthy of extensive clinical ap plication.
