[Abstract] 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 (χ2=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 (χ2=0.000, P=1.000). In the observation group, the consumables cost of 50 yuan for 14 cases (56.00%), 100 yuan for 5 cases (20.00%), 150 yuan for 3 cases (12.00%), and 3 cases (12.00%) for intermittent suture after local anesthesia debridement after incision, a total of 2 550 yuan was used. Each patient in the control group was free of charge with one existing disposable negative pressure drainage protection material (moisturizer), worth 3 280 yuan per piece, of which 19 patients used one post-granulation ruddy and incision healing without follow-up costs; 3 patients used one more, with a total cost of 9840 yuan; Two patients added intermittent sutures after local anesthesia debridement after using two VSD consumables, the cost was 13 120 yuan, and 1 patient added three VSD consumables after incision local anesthesia debridement intermittent suture with 9 840 yuan. The usage fee is 32 800 yuan. 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.
