简易负压封闭引流技术在25例腹部创伤患者感染切口中的应用效果

Clinical Effect of Simple Negative Pressure Sealing Drainage Technique in 25 Patients with Abdominal Trauma

目的观察简易负压封闭引流技术在腹部创伤患者感染切口中的应用效果。方法对照组(n=25)给予现有负压封闭引流VSD材料治疗感染切口,观察组(n=25)给予简易负压封闭引流技术治疗感染切口,对比两组的冲洗引流效果、肉芽组织生长影响、耗材费用及切口愈合时间。结果两组患者冲洗引流通畅均为24例(96.00%),VSD出现管路堵塞,引流不畅各1例(4.00%),两组冲洗引流效果比较,差异无统计学意义(χ^(2)=0.000,P=1.000)。观察组使用VSD后创面清洁、肉芽红润、切口可自愈者22例(88.00%),需使用2次及以上VSD、切口需清创后间断缝合者3例(12.00%);对照组使用VSD后创面清洁、肉芽红润、切口可自愈者22例(88.00%),需使用2次及以上VSD、切口需清创后间断缝合者3例(12.00%),两组肉芽组织生长影响比较,差异无统计学意义(χ^(2)=0.000,P=1.000)。对比两组耗材费用使用情况,对照组在去除免费使用的基础之上,其耗材使用费用是观察组的12.86倍,远高于观察组简易耗材使用费用。所有患者切口愈合良好,观察组切口愈合时间(11.96±3.61)d,对照组切口愈合时间(11.52±3.22)d,差异无统计学意义(t=0.455,P=0.651)。结论简易VSD与现有VSD应用于腹部创伤感染患者具有同样的冲洗引流效果,使用VSD后两组患者肉芽组织均生长红润,切口愈合良好,愈合时间无差异,效果相当,促进感染创面有效愈合。但使用简易VSD耗材费用明显低于现有VSD耗材费用,减轻患者经济负担。

Objective This study aims to observe the application effect of simple negative pressure sealing drainage technique in the infected incision of patients with abdominal trauma.Methods The control group(n=25)was treated with the existing negative pressure sealing drainage VSD material to treat the infected incision,and the observation group(n=25)was treated with the simple negative pressure sealing drainage technology to treat the infected incision.It compared the effect of washing and drainage,the effect of granulation tissue growth,the cost of consumables and the time of wound healing.Results There were 24 patients(96.00%)with smooth irrigation and drainage in both groups,1 case(4.00%)with pipeline blockage and poor drainage in VSD,and there was no significant difference in the effect of irrigation and drainage between the two groups(χ^(2)=0.000,P=1.000).In the observation group,22 cases(88.00%)had clean wounds,rosy granulations,and self-healing incisions after VSD,3 cases(12.00%)needed to use VSD twice or more,and intermittent sutures after debridement.In the control group,22 cases(88.00%)had clean wounds,rosy granulations,and self-healing incisions after VSD,3 cases(12.00%)who needed VSD for 2 or more times,and intermittent sutures after debridement of incisions,and there was no significant difference in the growth effects of granulation tissue between the two groups(χ^(2)=0.000,P=1.000).Compared with the use of consumables between the two groups,the cost of consumables in the control group was 12.86 times that of the observation group on the basis of removing free use,which was much higher than that of the observation group.The incision healing time of all patients was(11.96±3.61)d,and the incision healing time of the control group was(11.52±3.22)d,and there was no significant difference in the incision healing time between the two groups(t=0.455,P=0.651).Conclusion Simple VSD has the same irrigation and drainage effect as existing VSD in patients with abdominal trauma infection,and the granulation tissue of the two groups after VSD is grown red,the incision heals well,there is no significant difference in healing time,and the effect is comparable,which promotes the effective healing of infected wounds.However,the cost of using simple VSD consumables is significantly lower than the cost of existing VSD consumables,which reduces the economic burden of patients.
