Abstract:
Objective:To investigate the clinical effects of autologous platelet rich plasma gel (PRP) combined with vacuum sealing drainage (VSD) technology on the repair of refractory wounds.Methods:From March 2011 to January 2015, 44 patients with refractory wounds and conformed to the inclusion criteria were included into VSD alone group, who were admitted to the Department of Burn and Plastic Surgery of the Yidu Central Hospital of Weifang and received intermittent VSD treatment. From February 2015 to September 2019, 43 patients with refractory wounds and conformed to the inclusion criteria were included into PRP+VSD group, who were admitted to the same unit above-mentioned and received PRP combined with intermittent VSD treatment.The retrospective cohort study was conducted. There were 24 males and 20 females with ages of (37.5±2.2) years in VSD alone group, and there were 25 males and 18 females with ages of (37.0±2.5) years in PRP+VSD group. The wound secretions of patients in the two groups before and 7, 14 d after the first treatment were collected for bacterial culture, and the positive rate of bacterial culture was calculated.The wound healing of patients in the two groups was observed on 7, 14,and 21 d after the first treatment, and the wound healing rate was calculated. The complete wound healing time of patients in the two groups was recorded. The degree of wound pain of patients in the two groups was evaluated by the visual analog scale (VAS) before and 14 d after the first treatment. The scar hyperplasia of patients in the two groups was evaluated by the Vancouver Scar Scale (VSS) in 1 and 2 months after the wound healed completely.The incidence of adverse reactions of patients in the two groups after the treatment was observed and the incidence of adverse reactions was calculated.Data were statistically analyzed with analysis of variance for repeated measurement, chi-square test, paired t test, and Bonferroni correction.Results:The positive rates of bacterial culture of patients in PRP+VSD on 7 and 14 d after the first treatment were 37.2% (16/43) and 11.6% (5/43), which were significantly lower than 56.8% (25/44) and 29.5% (13/44) in VSD alone group, χ2= 4.212, 4.255, P<0.05. The wound healing rates of patients in PRP+VSD group on 7, 14 and 21 d after the first treatment were (58±14)%, (70±13)%, (89±12)%, which were significantly higher than (41±11)%, (60±11)%, (74±12)% in VSD alone group, t=6.323, 3.820, 5.751, P<0.01. The complete wound healing time of patients in PRP+VSD group was (30±6) d, which was significantly shorter than (61±8) d in VSD alone group, t=20.89, P<0.05. The VAS score of patients in PRP+VSD group was significantly lower than that in VSD alone group (t=13.904, P<0.01). The VSS score of patients in PRP+VSD group was significantly lower than that in VSD alone group in 1 and 2 months after the wound healed completely (t=3.307, 3.637, P<0.01). The incidence of adverse reactions of patients in PRP+VSD group after the treatment was 7.0% (3/43),which was significantly lower than 22.7% (10/44) in VSD alone group alone, χ2=4.245, P<0.05. Conclusions:Autologous PRP gel combined with VSD technology to repair refractory wounds not only has good bacteriostatic effect, but also can increase wound healing rate, shorten wound healing time, reduce wound pain, relieve scar hyperplasia, and without adverse reactions, which is worthy of promotion.
