Background: Negative Pressure Wound Therapy (NPWT) is used in the treatment of various wounds. The study demonstrates a novel use of vessel patch as a sealant of mucosal orifice fistulas. Methods: The study included ten patients with orocutaneous fistulas in the course of treatment of oral malignancies. Patients were divided into treatment (NPWT) and control (conventional dressings) group. In four cases, the vessel patch was applied. We used the Hartmann Vivano system with 50 mmHg to 130 mmHg negative pressure values. Results: The median age of patients was 61.5 years (range: 31 -- 73 years). The median treatment time was 83 days (range: 14 -- 272 days). The median total treatment cost was 5.300 EUR (range: 2490 -- 7821 EUR) in the NPWT group and 12.000 EUR (range: 3.060 -- 22.745 EUR) in the control group. Conclusion: The use of NPWT is a cost-effective and reasonable method for the management of orocutaneous fistulas and other complications in maxillofacial surgery.

Objective: Knowledge of wound bioburden can guide selection of therapies, for example, the use of negative pressure wound therapy (NPWT) devices with instillation in a heavily contaminated wound. Wound and periwound bacteria can be visualised in real-time using a novel, non-contact, handheld fluorescence imaging device that emits a safe violet light. This device was used to monitor bacterial burden in patients undergoing NPWT. Methods: Diverse wounds undergoing NPWT were imaged for bacterial (red or cyan) fluorescence as part of routine wound assessments. Results: We assessed 11 wounds undergoing NPWT. Bacterial fluorescence was detected under sealed, optically-transparent (routine) adhesive before dressing changes, on foam dressings, within the wound bed, and on periwound tissues. Bacterial visualisation in real-time helped to guide: (1) bioburden-based, personalised treatment regimens, (2) clinician selection of NPWT, with or without instillation of wound cleansers, and (3) the extent and location of wound cleaning during dressing changes. The ability to visualise bacteria before removal of dressings led to expedited dressing changes when heavy bioburden was detected and postponement of dressing changes for 24 hours when red fluorescence was not observed, avoiding unnecessary disturbance of the wound bed. Conclusion: Fluorescence imaging of bacteria prompted and helped guide the timing of dressing changes, the extent of wound cleaning, and selection of the appropriate and most cost-effective NPWT (standard versus instillation). These results highlight the capability of bacterial fluorescence imaging to provide invaluable real-time information on a wound's bioburden, contributing to clinician treatment decisions in cases where bacterial contamination could impede wound healing.

Abstract Introduction Complex wounds (CW) resulting from necrotizing soft tissue infections (NSTIs) and soft tissue traumatic injuries create unique challenges. Radical debridement is often the first step in management but can result in disfigurement with impaired function and compromised cosmesis. The standard of care at our institution for full-thickness burn injuries of similar complexity is widely meshed autografting with application of autologous skin cell suspension (ASCS). Our study is a case series reviewing outcomes using ASCS for CW from non-burn etiology. Methods A retrospective chart review from March 2019 through July 2020 was performed to evaluate the effectiveness of ASCS and widely meshed autografting in CW. Patients presenting with CW underwent serial excisions of devitalized tissue by acute care and burn surgeons. Dermal substitute utilization for wound preparation was at the discretion of the surgeon. Definitive wound closure was achieved using ASCS in combination with a widely meshed autograft. The wounds were covered with a non-adherent, non-absorbent, small pore primary dressing along with bismuth-impregnated, petroleum-based gauze or negative pressure wound therapy dependent on wound bed contour. Further padding with gauze was applied along with compressive dressing. Results In total, 8 patients with CW were included in this review. The mean age was 58 years (range 27-85) with an equal number of males and females. Wound etiology included NSTI (n=5), degloving injury (n=2), and traumatic amputation (n=1). The average wound size measured 1,300cm2 (range 300-3,000). 50% of the patients were treated with a dermal substitute and negative pressure wound therapy prior to ASCS and autograft placement. 7 of 8 patients received split-thickness skin grafting in the ratio of 3:1 with one patient grafted at a 2:1 expansion. 7 of the 8 patients had >90% wound closure within 8-10 days of ASCS and autograft application. One patient had significant graft failure after removing surgical dressings and autograft in the early post-operative period secondary to dementia. One patient expired during the follow-up period secondary to medical comorbidities. The 6 remaining patients had durable wound closure and acceptable cosmetic outcome. All patients were discharged within 10 days of ASCS application with 4 patients discharging home and 4 patients discharging to an acute inpatient rehabilitation. Conclusions This study is the first case series to review ASCS in combination with widely meshed skin grafts in the management of CW from a non-burn etiology. Durable, timely wound closure and an acceptable cosmetic outcome was achieved in these often-challenging CW.

Background: Negative-pressure wound therapy (NPWT) or vacuum dressings involve the application of a controlled negative pressure on the wound. Traditionally, STSGs were fixed with bolster technique, where sutures are used to fix pressure dressings over the top of recently placed grafts. Taking it a step further in our study we applied an effective and user friendly filler material (surgical roll gauze) on very large defects. The objective of this study was to assess the clinical efficacy of gauze-based negative pressure wound therapy as an adjunctive therapy to STSG, over complex and very large wounds. Material & Methods: This descriptive study was conducted at Army Burn Center, Combined Military Hospital Kharian and PNS Shifa Hospital Karachi from January 2016 to June 2017. Gauze based VAC system used. Negative pressure was applied at -80 mm Hg. Evaluation was carried out to assess the performance of gauze-based NPWT. Results: Total of 63 patients, 42 males and 21 females, with mean age of 32 years SD+15 were included in the study. The wound size included in the study ranged from 12x10 cm to 88x66 cm. Mean duration of NPWT dressings was 15 days and 313 dressings were employed in total with satisfactory healing achieved in 3 to 4 VAC dressings in most of the cases. Mean duration of hospital stay was 23.92 days at which point graft uptake percentage was in the range of 90% (n=7) to 100% (n=20). Only 3.2% (n=2) cases required partial re-grafting for complete coverage of residual wounds. Conclusion: Gauze-based Negative-pressure wound therapy over split thickness skin graft is a cost-effective addition to the care and management of large and complex wounds

To improve healing of pressure ulcer wounds, it is important to optimize the conditions of the area surrounding the wound. Negative pressure wound therapy (NPWT) promotes wound healing, however, the removal of NPWT can cause pain or focal bleeding, delaying wound healing or causing infection. In this study, we reviewed the efficacy of the lipidocolloid non-adherent dressing (Urgotul®) as a wound contact layer. A total of 38 patients from the same facility who applied NPWT from April 2016 to October 2019 were included and divided into two groups; NPWT with the lipidocolloid non-adherent dressing (group 1, experimental group, 19 patients) and NPWT only (group 2, control group, 19 patients). The condition of the wound was examined prior to NPWT application, at one week, and again at three weeks after application. No significant differences were found between groups for general characteristics, bacterial culture or photo analysis. However, when comparing groups based on the time of examination, there was a significant reduction of the wound size in group 1 (p = 0.001) but not in group 2 (p = 0.082). Therefore, the current study finds that using the lipidocolloid non-adherent dressing as a wound contact layer in NPWT stimulates healing by shrinking the size of the pressure ulcer wound.

Abstract Background The use of negative pressure wound therapy (NPWT) in colorectal surgery has been demonstrated for treating perineal defects, enterocutaneous fistula and stoma dehiscence. Here we describe a technique for closure of complex stoma-associated wounds using a novel commercial intubation device alongside NPWT to protect the surrounding wound from the stoma effluent. The device has previously described for use with enterocutaneous fistula. We present two cases that have been successfully treated with this technique. Technique and Cases The first case is of 88-year-old women with a retracted loop ileostomy and the second a 48 year-old male with a retracted end colostomy. Both patients underwent significant emergency peristomal debridement and in both cases the commercial device was deployed to intubate the stoma. VAC foam and standard adhesive dressings were used to form a quality seal and the pressure set to 125mmHg. In both cases near complete healing was achieved to the point that standard stoma bags and management could be used. Conclusions This is the first description of the use of an isolation device in complex stoma associated wounds. We have found the Fistula Funnel to be highly effective in this context.

Negative-pressure wound therapy (NPWT) involves the application of subatmospheric pressure to a wound to help in the healing process. The objective of this case series was to evaluate the clinical experience using ultra-portable NPWT devices on high-risk closed incisions after surgical management of complex non-healing wounds. Data were available for eight dogs and three cats. Wound aetiologies varied from traumatic, neoplastic and foreign body. Application and maintenance of the portable device were technically easy in most cases, finding some difficulties when applied to curved body surfaces. All patients’ outcome was highly rewarding. This case series suggests that portable NPWT helps in achieving full recovery, increases comfort allowing early ambulation and feeding, and reduces hospitalisation time. Their reduced size is suitable for smaller animals, enhancing their therapeutic use in veterinary medicine.

Dressing Change

Negative pressure wound therapy (NPWT) is a technique using vacuum dressing to promote wound healing in complicated wound. However, for many patients, the application and removal of the NPWT is source of procedural pain. The authors hypothesized that administering cold sterile water into the NPWT sponge would decrease pain during dressing changes. A prospective randomized controlled study was conducted on 27 patients who were undergoing 81 NPWT wound dressing changes (n = 81) at a single institution between October 2016 and September 2017. Each patient had 3 NPWT dressing changes. Cold sterile water (5.74 °C), room temperature sterile water (26.89 °C), and nothing were randomized and administered in the NPWT tubing into the sponge 10 minutes before changing the dressing in each and every procedure. Pain scores were assessed using a 0 to 10 numeric pain scale. Patients administered with cold water reported less pain than those administered with room temperature sterile water during the dressing change (4 vs 5.67; P < .003), and much less pain than those with nothing instilled before dressing change (4 vs 6.59; P < .001). There is no statistically significant difference in pain score between using the room temperature sterile water group and the control group that instilled nothing (5.67 vs 6.59; P = .065). This study has shown that cold water administered through the suction tubing before the dressing change had a better reduction in pain score than using room temperature sterile water and the control group.
