Objective To investigate the effect of vacuum sealing drainage (VSD) combined with autologous platelet-rich plasma gel (PRP) on postoperative wound infection and chronic poor wound healing, so as to provide more economical and safe treatment in clinic.Methods The patients with postoperative wound infection and chronic poor wound healing in the Second Affiliated Hospital of Nanchang University and Sixth Affiliated Hospital of Sun Yat-sen University from September 2018 to July 2019 were collected, then were divide into PRP+VSD group and VSD group according to treatment methods. The patients in the PRP+VSD group were filled with PRP and activator calcium thrombin following debridement, then covered with silver ion dressing and continuous VSD; in the VSD group were directly covered with silver ion dressing and then continuous VSD. The general situations of patients in the two groups during the process of replacing the VSD and the wound condition during dressing replacing were observed.Results There were 100 patients in this study, 50 in the PRP+VSD group and 50 in the VSD group. There were no significant differences in the age, gender, body mass index, wound area before treatment, and wound infection type between the two groups (P>0.05). Compared with the VSD group, the PRP+VSD group had higher score of fresh granulation tissue coverage area (P<0.05), shorter wound closure time (P<0.05), shorter wound healing time (P<0.05), lower pain score (P<0.05), and less hospitalization expenses (P<0.05), lower rates of second debridement (P<0.05) and recurrent infection (P<0.05).Conclusion Autologous PRP combined with VSD in treatment of postoperative wound infection and chronic poor wound healing could shorten growth time of wound granulation tissue, promote rapid wound healing, reduce cost, and provide an economic, safe, and effective treatment method for clinical practice.
