Application of closed negative pressure drainage technique in repair of wound of hand trauma infection

Objective To explore the application value of closed negative pressure drainage technique in wound healing of hand trauma. Methods From August 2013 to October 2017, 80 patients with hand trauma in the Traditional Chinese Medicine Hospital of Cixi were divided into two groups according to the random principle, with 40 cases in each group.The control group was treated with conventional wound repair, and the observation group was treated with closed negative pressure drainage.The repair effect, healing, secondary operation, antibiotic use, hospitalization, histopathological score and patients' satisfaction were observed. Results The total effective rate of the observation group (97.50%) was obviously higher than that of the control group(80.00%)(χ2=6.13, P<0.05). The time of healing, length of hospital stay and the use time of antimicrobial agents in the observation group were (15.11±2.43)d, (16.27±1.79)d and (6.06±0.65)d, respectively, which were all lower than those in the control group(t=14.43, 13.31, 23.29, all P<0.05). The second operation rate of the observation group (5.00%) was lower than that of the control group(P<0.05), and the histopathological score in the observation group (7.11±0.53) was higher than that in the control group(P<0.05). The satisfaction rate of the observation group (100.00%) was obviously higher than that of the control group(χ2=6.49, P<0.05). Conclusion In the treatment of wound healing of hand trauma, the application of closed negative pressure drainage technology is better, which can effectively control the disease and is worthy of further promotion and use.
