Negative-pressure wound therapy is effective for peritoneal dialysis catheter exit-site management in the early postoperative period

AbstractPeritoneal dialysis (PD) catheter exit-site care is critically important for the prevention of catheter-related infections (CRIs) and subsequent peritonitis. The postoperative management of the site is particularly essential because it has an open wound that is always adjacent to a PD catheter tube. This study aimed to examine the effectiveness of negative-pressure wound therapy (NPWT) for postoperative PD catheter exit sites. Thirty patients with end-stage renal disease who underwent simultaneous PD catheter insertion and exit-site formation were randomly assigned to receive NPWT (NPWT group) or conventional dressing (non-NPWT group) for the first seven postoperative days. The exit-site scores on the seventh postoperative day was lower in the NPWT group than in the non-NPWT group (p = 0.0049). Analysis of variance F statistic for the effect of NPWT over 180 days was highly significant (11.482595, p = 0.007). There were no statistically significant differences between the time to first CRI and PD-related peritonitis between the two groups. There was one case of CRI with relapsing peritonitis and catheter loss in the non-NPWT group. These findings demonstrate the association between NPWT and low exit-site score. NPWT can be recommended for the management of PD catheter exit sites in the early postoperative period.

Abstract Peritoneal dialysis (PD) catheter exit-site care is critically important for the prevention of catheter-related infections (CRIs) and subsequent peritonitis. The postoperative management of the site is particularly essential due to its susceptibility to slow healing and infection. Despite the recent use of negative-pressure wound therapy (NPWT) for a wide variety of wounds, few studies have investigated the effectiveness of NPWT for PD catheter exit sites. In this study, 30 patients with end-stage renal disease who underwent simultaneous PD catheter insertion and exit-site formation were randomly assigned to receive NPWT (NPWT group) or conventional dressing (non-NPWT group) for the first seven postoperative days. The exit-site scores on the seventh postoperative day and over 180 days were lower in the NPWT group than in the non-NPWT group (p = 0.0049 and p = 0.007, respectively). There were no statistically significant differences between the time to first CRI and PD-related peritonitis between the two groups. There was one case of CRI with relapsing peritonitis and catheter loss in the non-NPWT group. These findings demonstrate the association between NPWT and low exit-site score. NPWT can be recommended for the management of PD catheter exit sites in the early postoperative period.

Total ear reconstruction is being practiced by different techniques. Ready to use Silicone ear framework (Silastic ear framework by Dow corning) was being used frequently by Plastic surgeons in the eighties and nineties of the twentieth century. Framework exposure, either due to skin necrosis or due to infection used to be the commonest complication in the early postoperative period. A follow-up case of a 50 year old male patient, our 33 years follow up case of Total ear reconstruction by silicone ear framework implantation presented to us with exposed silicone framework and infection. Due to constant use of facemask with elastic ear loop for support during COVID-19 pandemic. The exposed infected implant successfully salvaged using negative pressure wound therapy. In all cases of autologous or alloplastic ear reconstruction, we strictly recommend not to use facemasks with elastic ear loops. If a facemask has to be used it should have a head loop or to be used with an ear protector.

Ventral Hernias

An algorithm for the diagnosis and treatment of infectious and inflammatory complications after endovideosurgical hernioplasty in patients with postoperative ventral hernias using traditional and minimally invasive methods of therapy was proposed. The study was based on the treatment results of 177 patients who underwent endovideosurgery for postoperative ventral hernias. Despite the perioperative antibiotic prophylaxis according to the accepted at the S.M. Kirov Military Medical Academy, according to the protocol scheme (first-generation cephalosporin at a dose of 1 g once parenterally 30 min before the operation, followed by repeated administration in case of operation duration of 3 h), course of the early postoperative period on days 35 in 8 (4,5%) patients after endovideosurgical hernioplasty was complicated by suppuration in the intervention area. When analyzing the causes of infectious and inflammatory complications, in both the main and control groups of observations, all suppuration in the area of surgical interventions was diagnosed in patients with metabolic syndrome (stages IIIII obesity and type 2 diabetes mellitus). The use of the negative pressure wound therapy resulted in wound cleansing for 4.1 2.5 days (p 0.05) and was comparable with the traditional method of treatment, but more active growth of granulation tissue prevailed in the wound, which contributed to its accelerated healing. The negative pressure wound therapy is effective in the systemic infectious and inflammatory process, especially after prosthetic hernioplasty of large W3-postoperative hernias. Drainage of abscesses under ultrasound navigation is possible with small (S 10 cm2) delimited purulent processes in the area of the polypropylene implant with the preservation of the latter.

Abstract Background: Compare the complications of patients undergoing total knee arthroplasty (TKA) who used a portable negative-pressure wound therapy (NPWT) device in the immediate postoperative period with those of a control group. Methods: A total of 296 patients were evaluated. Patients were divided into two groups: those who used NPWT for seven days in the postoperative period (Group 1) and those who used conventional dressings (Group 2). Demographic data, comorbidities, local parameters related to the surgical wound and complications were evaluated.Results: The groups did not differ in regard to sex, age and clinical comorbidities. Overall, 153 (51.7%) patients had at least one risk factor for wound complications. Patients who used NPWT had a lower rate of complications (28.5% vs. 45.7%, p = 0.001) and a lower rate of reintervention in the operating room (2% vs. 8.5%, p = 0.001). Patients in group 1 had a lower incidence of hyperaemia (14.7% vs. 40.2%, p = 0.01), skin necrosis (2.1% vs. 8.5%, p = 0.04) and wound dehiscence (3.1% vs 10.1%, p = 0.03). The use of NPWT was a protective factor for the presence of complications, with an odds ratio of 0.36 (95% CI 0.206-0.629).Conclusion: The number of complications related to the wound after TKA is high; however, most of them are minor and have no impact on the treatment and clinical evolution of patients. The use of NPWT decreased the number of surgical wound complications, especially hyperaemia, dehiscence and necrosis, and reduced the need for reintervention.

Objectives The aim of this study was to retrospectively review the effectiveness of negative pressure wound therapy (NPWT) in sternal wound healing with the use of the validated Bates-Jensen Wound Assessment Tool (BWAT), and explore the role of NPWT over sternal wounds and future treatment pathways. Methods Data was gathered from patients' medical records and the institution's database clinical management system. Seventeen subjects, who had undergone cardiothoracic surgeries and subsequently consulted the wound care team in one year were reviewed. Fourteen of them were included in the analysis. Healing improvement of each sternal wound under continuous NPWT and continuous conventional dressings was studied. In total, 23 continuous NPWT and 13 conventional dressing episodes were analysed with the BWAT. Results Among conventional dressing episodes, sternal wound improvement was 2.5–3% over 10 days to 3.5 weeks, whereas 4–5% sternal healing was achieved in 5 days to 2 weeks with sternal wire presence. Better healing at 11% in 1 week by conventional dressing was attained after sternal wire removal. In NPWT episodes, 8–29%, 13–24%, and 15–46% of healing was observed in 2 weeks, 3.5 to 5 weeks and 6 to 7 weeks, respectively. Only 39% wound healing was acquired at the 13th week of NPWT in one subject. With sternal wire present, 6%–29% wound healing progress was achieved by NPWT in 1–4 weeks, and 16–23% wound improvement in 2 to 4.5 weeks by NWPT after further surgical debridement. After sternal wire removal, 6–34% sternal wound healing occurred by continuous NPWT for 1–2 weeks, and maximum healing at 46% after 2.5 weeks of NPWT were observed. Conclusions Better wound healing was achieved in the NPWT group in comparison to conventional dressings alone. However, suboptimal sternal wound healing by NPWT alone was observed. Removal of sternal wire may improve the effectiveness of NPWT. Successful tertiary closure after NPWT among subjects supports the important bridging role of NPWT in sternal wound healing. Factors causing stagnant sternal wound healing by NPWT alone are discussed.
