The aim of this study was to investigate the therapeutic effects of vacuum sealing drainage (VSD) on wound repair time and inflammation‐related indicators in patients with soft‐tissue wounds in comparison with traditional treatment. From January 2018 to January 2020, 130 enrolled patients with soft‐tissue wounds were randomly divided into two groups: VSD group (65 cases) and routine dressing change (RDC) group (65 cases). The inflammation‐related indicators including erythrocyte sedimentation rate (ESR), C‐reactive protein (CRP), white blood cell (WBC), and procalcitonin (PCT) of preoperative stage and postoperative day 3 (POD 3) and POD 7 were recorded. Wound healing was observed 3 and 7 days after treatment, and the clinical efficacy, changes in the wound (coverage rate and thickness of granulation tissue and bacterial clearance rate), wound‐cleaning time, wound‐healing time, and hospital stay time were recorded after treatment as well. No significant difference was observed in terms of the baseline between the two groups. On POD 3 and POD 7, CRP, WBC, and PCT levels in the VSD group were lower than those in the RDC group, while ESR levels were higher, with significant differences (P < .05). After treatment, the wound‐cleaning time, wound‐healing time, and hospital length of stay of the VSD group were all lower than those of the RDC group, with significant differences (P < .05). VSD has a significant effect on the treatment of patients with soft‐tissue wounds, which can effectively shorten the time of wound healing and reduce inflammation‐related indicators. Compared with traditional RDC, VSD is more worthy of clinical application.
To observe the effect of application of incentive nursing intervention (INI) on recovery in burn patients undergoing vacuum sealing drainage (VSD). From January 2017 to January 2020, a total of 82 consecutive burn patients were prospectively enrolled, and divided into INI group and routine nursing intervention (RNI) group according to random number table method. The causes of inadequate drainage were collected, the incidence was calculated, and the occurrence of inadequate drainage at different locations was compared. The pain degree and comfort status before and after the intervention were observed, and the wound healing time, hospital stay, and satisfaction after the intervention were recorded. The reasons for inadequate drainage during the
Objective: To evaluate the effects of injectable platelet-rich fibrin (i-PRF) produced by a simple twice-centrifugation method combined with vacuum sealing drainage on wound inflammation and scar formation in chronic refractory wounds (CRW).Methods: A total of sixty-eight patients with CRW who were admitted to our hospital were enrolled in this study. They were then randomly divided into the study group (n = 34) with being treated using negative pressure sealing and drainage technology, and the control group (n = 34) with being treated using injectable platelet-rich fibrin in conjunction with negative pressure sealing and drainage technology. The following were the primary outcomes: scar conditions at 1 and 3 months after the wound was fully healed, wound healing time, hospitalization time, wound healing rate, incidence of adverse reactions, serum inflammatory indices, and pain levels were assessed 1 day before treatment and 14 days after treatment. The secondary outcomes were determined by comparing the proportion of positive bacterial cultures in the two groups on the day before therapy, as well as on the seventh and fourteenth days after treatment.Results: The wound healing time and hospital stay in the study group were significantly lower than that in the control group (all p < 0.001). The wound healing rate of the study group was significantly higher than that of the control group on the 14th day and 28th day after treatment (all p < 0.001). On the 14th day after treatment, the levels of WBC, CRP, and IL-6 in the study group were lower than those in the control group (all p < 0.001). The positive rate of bacterial culture in the study group was significantly lower than that in the control group on the 7th and 14th day after treatment (all p < 0.05). At 1 month and 3 months after treatment, the VSS score in the study group was lower than that in the control group (all p < 0.001). The total defect rate of the study group was also significantly lower than that of the control group (5.88% vs. 29.41%, p = 0.011).Conclusion: The i-PRF produced by simple twice-centrifugation method combined with VSD could reduce wound inflammation and improve scar formation in patients with CRW.
To explore the curative effect of insulin external application on burn wounds of diabetic patients with different depths. A retrospective analysis of 114 diabetic burn patients in the First Hospital of Hebei Medical University from June 2019 to June 2022. According to the different treatment methods, they were divided into study group (insulin therapy) and control group (conventional therapy) with 57 cases in each. The wound healing time, dressing changes, scar healing after wound healing and adverse events were compared between two groups. Pain level, serum inflammatory factors, vascular endothelial growth factor (VEGF) and oxidative stress factors before and after treatment were compared. The wound healing time (17.23 ± 2.18 vs 20.31 ± 2.09 days) and the number of dressing changes (7.01 ± 1.23 vs 8.93 ± 1.32 times) in study group were significantly lower than those in control group (P < 0.05). Before treatment, there was no difference in pain level, VEGF, interleukin‐1 (IL‐1), tumour necrosis factor‐α (TNF‐α), malondialdehyde (MDA) and superoxide dismutase (SOD) between two groups (P > 0.05). However, the pain level, scar healing, IL‐1, TNF‐a and MDA in study group were significantly lower than those in control group after treatment (P < 0.05). And the VEGF and SOD in study group was significantly higher than that in control group (P < 0.05). External application of insulin can shorten the wound healing time of diabetic patients with different depths, reduce the number of dressing changes, promote scar healing after wound healing, relieve pain and reduce the level of inflammatory factors, which is worthy of clinical promotion.
