Abstract
OBJECTIVE In conjunction with appropriate wound care, negative pressure wound therapy with instillation and dwell time (NPWTi-d) may be used as an adjunct therapy for acute or hard-to-heal (chronic) wounds, especially when infected. However, there are very few data on the use of NPWTi-d in the treatment of fibrinous wounds that are difficult to debride mechanically. The main objective of this study was to describe changes in the fibrin area of such wounds, before and after treatment with NPWTi-d. METHOD This was a monocentric, observational, prospective pilot study evaluating the NPWTi-d medical device. Eligible patients included in the study were those with hard-to-heal lower limb ulcers who had previously undergone unsuccessful specific debridement treatment for their wound, with failure of manual mechanic debridement for at least six weeks' duration, and whose wounds had a fibrinous surface area of >70% of the total wound surface area. The primary endpoint was the difference in the percentage of fibrinous surface area before and after treatment. RESULTS A total of 14 patients who received treatment for lower limb ulcers between October 2017 and August 2019 were included in the study. There was a significant shrinkage rate of the fibrinous wound surface between the start and end of treatment (83.6±14.5% and 32.2±19.7%, respectively; p<0.001). CONCLUSION This study showed a significant decrease in fibrin area in wounds treated with NPWTi-d, with good tolerance. We believe that NPWTi-d has its place in the multidisciplinary management of patients with hard-to-heal ulcers. Additional randomised studies are required to confirm these findings. DECLARATION OF INTEREST The authors have no conflicts of interest.

Abstract
Background Chronic limb-threatening ischemia (CLTI) is a severe peripheral artery disease with rest pain and lower limb ulceration. After revascularization, limb ulceration treatment should be completed quickly before restenosis. We aimed to investigate the effect of negative pressure wound therapy with instillation and dwell (NPWTi-d) using an antiseptic solution (AS) versus a saline solution (SS) in CLTI. There is no research limited to CLTI on this topic. Methods All patients underwent revascularization and surgical debridement. NPWTi-d was applied after surgical debridement. We evaluated wound tissue cultivation from pre- and post-NPWTi-d, length of NPWTi-d, and laboratory data pre- and post-NPWTi-d. All data are presented as the median, interquartile range. For univariate analysis, nonnormally distributed data were examined using the Wilcoxon rank sum test between the two groups of NPWTi-d (AS and SS group). A P value of less than 0.05 was considered statistically significant. Results Forty-eight CLTI patients participated. The SS group included 24 patients (19 men, five women, average age 68.8 years) and the AS group included 24 patients (16 men, eight women, average age 67.4 years). The comorbidities included 23 and 19 patients with diabetes mellitus and hemodialysis in the SS group, and 22 and 16 patients in the AS group, respectively. There were no adverse events in either group. Both groups reduced the number of bacteria. The AS group required shorter NPWTi-d time (P = 0.02). Conclusion The AS group was able to shorten the treatment duration in CLTI.

Abstract
Background Negative pressure wound therapy (NPWT) is commonly used in wound management of both acute and chronic wounds. As wound care has advanced, traditional NPWT has evolved to include instillation and dwell time (NPWTi-d). To better understand the potential clinical benefits of NPWTi-d, an assessment of the available literature focusing on NPWTi-d mechanisms of action in wound management was conducted. Methods. A literature search was performed for abstracts and articles published between 2010 and 2023. Published studies in English that discussed NPWTi-d mechanisms of action and included a study population larger than 10 patients were examined. Results A total of 1878 articles were identified through the literature search. After removal of duplicates and article reviews, 29 studies discussing the mechanisms of action for NPWTi-d were found. Study types included case series (n = 20), comparative study (n = 6), randomized controlled trial (n = 2), and retrospective study (n = 1). These studies included approximately 1108 patients who received NPWTi-d as part of a wound care treatment plan. NPWTi-d use was associated with improved wound and clinical outcomes through wound cleansing, removal of exudate and infectious materials, and promotion of granulation tissue development. Conclusions The mechanisms of action for NPWTi-d helps provide wound management through wound cleansing, removal of exudate and infectious materials, and promoting the development of granulation tissue. Additional studies are warranted to fully assess the potential clinical and health economic benefits of NPWTi-d use.

Abstract
Background and Aims Negative pressure wound therapy (NPWT) has gained a central role in the treatment of deep sternal wound infections (DSWIs) after median thoracotomy. Our study aims at proving the safety of using NPWT with instillation and dwell time (NPWTi-d) in the treatment of DSWI. Methods We retrospectively evaluated the patients who were treated at our institution between March 2018 and November 2021 for DSWI after radical sternectomy using NPWT or NPWTi-d. The NPWTi-d was applied to start the first postoperative day using 75 mmHg negative pressure for 3 h, followed by instillation of sodium hypochlorite <0.08% with a 3-min dwell time. Results The NPWTi-d group showed a shorter length of stay (29.39 ± 12.09 vs. 39.54 ± 17.07 days; p = 0.049), a shorter elapsed time between the debridement and the flap coverage (7.18 ± 4.27 vs. 11.86 ± 7.7 days; p = 0.003) and less operative or nonoperative dressing changes (1.73 ± 1.14 vs. 2.68 ± 56; p < 0.001). The in-hospital mortality was 8.2%, with no significant differences between the two groups (p = 1). Conclusion NPWTi-d can be safely employed in the treatment of DSWI. Further prospective randomized studies need to establish the role of NPWTi-d in the control of infection and biofilm as well as in wound healing.

Abstract
Sternal osteomyelitis is a rare but devastating complication of median sternotomy. To achieve good outcomes, it should be diagnosed early and treated appropriately. Standard treatment involves antibiotics, debridement, and reconstruction with flaps. To prevent flap complications and recurrence, the wound bed must be prepared carefully. One approach, a recent development, is negative pressure wound therapy with instillation and dwell time (NPWTi-d), where suction cycles are interspersed with wound instillation with solutions. NPWTi-d is currently cautioned against for large trunk wounds and cavities because it might alter core body temperature. Here, we report a new NPWTi-d dressing technique that is associated with successful reconstruction in two severe sternal osteomyelitis cases with wound sizes of 29 × 10 and 28 × 8 cm. This "delay-dressing technique" involves manually pulling the wound edges together; inserting a thin strip of dressing foam; applying dressing film strips from one side of the chest wall to the other, thus placing strong stretching tension on the normal skin around the wound; and then applying NPWTi-d. In our cases, we used the V.A.C. Ulta system for 20 and 17 days. The successful reconstruction in both cases may reflect good wound bed preparation and flap preconditioning due to the mechanical stress imposed by NPWTi-d. Thus, this dressing technique with the V.A.C. Ulta system may be an effective treatment option for sternal osteomyelitis cases.

Effects of negative pressure wound therapy with instillation and dwell time (NPWTi-d) versus NPWT or standard of care in orthoplastic surgery: A systematic review and meta-analysis. Int Wound J 2023. [PMID: 36594491 DOI: 10.1111/iwj.14072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Revised: 12/15/2022] [Accepted: 12/21/2022] [Indexed: 01/04/2023] Open
Abstract
Negative pressure wound therapy (NPWT) is a wound-dressing system that applies sub-atmospheric pressure on the surface of a wound to promote healing. An evolution of this technology, NPWT with solution instillation and dwell time (NPWTi-d), is increasingly being used to maximise wound closure and reduce failure rates. However, there is still a lack of evidence concerning its use in orthoplastic surgery. Therefore, the aim of this study is to compare NPWTi-d with NPWT and standard of care for wound management in orthoplastic surgery. A comprehensive literature search using PubMed, Web of Science, and Cochrane databases up to 15 March 2022 was performed, including studies describing the outcomes of NPWTi-d for traumatic/orthopaedic injuries. A meta-analysis on the number of surgical debridements, as well as the rate of complete wound closure and complications was carried out, although for other outcomes, a descriptive statistic was applied. Risk of bias and quality of evidence were assessed using the Downs& Black's Checklist for Measuring Quality. Thirteen studies with a total number of 871 patients were included, in which NPWTi-d demonstrated significantly higher primary wound closure and lower complication rates (P < .05). No difference in the number of surgical procedures required for final wound healing was observed. Moreover, five out of six studies showed better results for NPWTi-d when the change of the bioburden and bacterial count of the wound were analysed. A singular study investigating the length of the hospital stay of patients treated with NPWTi-d showed a reduction in the latter. The present meta-analysis proves that NPWTi-d is superior to NPTW or conventional dressings in orthoplastic wound care management, in terms of complete wound closure rate and the reduced number of complications. Still, the limited quality of the studies analysed shows that future randomised studies are needed to confirm the benefits and to identify the most appropriate recommendations for using NPWTi-d in orthoplastic surgery, as well as to investigate the cost-effectiveness of this wound-dressing system.

Is There a Wound Recontamination by Eluates with High Bacterial Load in Negative-Pressure Wound Therapy with Instillation and Dwell Time? Plast Reconstr Surg 2023; 151:136e-147e.

Abstract
BACKGROUND This study investigated bacterial colonization of the foam eluate after negative-pressure wound therapy (NPWT) with instillation and dwell time (NPWTi-d) to obtain an indication of possible recontamination of the wound during NPWTi-d. To detect bacterial colonization and the extent of planktonic and nonplanktonic bioburden as comprehensively as possible, routine culture and molecular biology methods were used. METHODS Before (time point 1) and after (median 3.0 days; time point 2) NPWT ( n = 15) and NPWTi-d with antiseptic installation ( n = 15), wound bed [22 acute, eight chronic wounds; median age, 51 years (range, 24 to 91); 26 men], foam, and eluate were examined by routine culture methods and fluorescence in situ hybridization (FISH), polymerase chain reaction, and FISH sequencing (FISHseq). RESULTS At time point 2, 94.9% (37 of 39) of the pathogens identifiable in the eluate were also detected in the wound bed. Foam and eluate were always bacterially contaminated. NPWTi-d resulted in a significant reduction in the number of pathogen species compared with NPWT (NPWTi-d, time point 1 versus time point 2: P = 0.026; NPWT, time point 1 versus time point 2: not significant). Routine culture of wound bed samples at time point 2 identified only 28 of 52 (53.8%) of the pathogens, whereas examination of wound bed, foam, and eluate and additional FISHseq use detected 50 of 52 (96.2%) of the bacterial species. FISHseq identified biofilm in one and microcolonies in 10 wounds (time point 2). CONCLUSIONS The bacterial load of the foam is flushed back into the wound during NPWTi-d. FISHseq should be used in addition to the routine culture method when pathogen identification and detection of nonplanktonic bacterial growth is particularly important for the patient's therapy.

The Effect of Negative-Pressure Wound Therapy with Instillation Compared to Current Standard Care on Wound Closure Time of Infected Wounds: A Systematic Review and Meta-Analysis. Plast Reconstr Surg 2022; 150:176e-188e.

Abstract
BACKGROUND Infected wounds extend healing time and are associated with higher treatment costs than noninfected wounds. Several observational studies indicate that negative-pressure wound therapy with instillation can effectively reduce bacterial bioburden and improve wound healing. Only a few randomized trials with small sample sizes have been published, and a meta-analysis directly comparing negative-pressure wound therapy with instillation to current standard care is lacking. It is therefore uncertain whether negative-pressure wound therapy with instillation actually improves wound healing. The authors performed a systematic review and hypothesized that negative-pressure wound therapy with instillation reduces wound closure time. METHODS The PubMed, Embase, and CENTRAL databases were searched up to December of 2020 for English studies that compare negative-pressure wound therapy with instillation-to either negative-pressure wound therapy without instillation or to other types of wound care-for the treatment of acute or chronically infected wounds. Time to wound closure was analyzed using a random effects meta-analysis in predefined subgroups according to study design and comparative wound care. RESULTS The authors identified 14 studies describing 1053 patients. Meta-analysis of three randomized trials shows no significant difference in time to wound closure between negative-pressure wound therapy with instillation and that without (mean difference, 0.48 day; 95 percent CI, -0.70 to 1.65; I ² = 0 percent). Data from eleven observational studies indicate that negative-pressure wound therapy with instillation reduces wound closure time (from 1.6 to 16.8 days; no pooled data). Because of imprecision and risk of bias, the available evidence provides only low-level certainty. CONCLUSIONS There is currently insufficient evidence to support or discard the use of negative-pressure wound therapy with instillation for infected wounds. More randomized trials are needed to determine whether a beneficial effect can be substantiated.

Abstract
BACKGROUND We investigated the effects of hydrodebridement with pulsed lavage (HDPL) and negative pressure (NP) wound therapies, instead of excising the prosthetic graft, in patients with postoperative thoracic vascular graft infection (TVGI). METHODS Between 2020 and 2021, five TVGI patients aged 49.6 ± 19.4 years old underwent a combined therapy of HDPL and NP. The patients underwent a two-step procedure (first step: re-sternotomy and HDPL; second step: NP) every 3 or 4 days. After negative tissue culture, the patients underwent omentum flap wrapping and skin closure. RESULTS No hospital death was observed. The time to skin closure was 10.8 ± 3.4 days. The time to the day in which bacteria were not cultured was 3.5 ± 2.4 days. No recurrent infections occurred for 241 ± 186 postoperative days. CONCLUSION Our strategy for TVGI patients may contribute to (1) sufficient infection control, (2) physical rehabilitation, and (3) less invasiveness for high-risk patients.

Abstract
An economic model was developed to estimate the cost of negative pressure wound therapy with instillation and dwelling of a topical wound solution vs control therapies. Economic model inputs were means derived from the results of a recently published systematic review and meta‐analysis of 13 comparative studies of negative pressure wound therapy with instillation. Means across studies comprising complex acute and chronic wounds for negative pressure wound therapy‐instillation vs control (negative pressure wound therapy without instillation, gauze dressings, or gentamicin polymethylmethacrylate beads) groups were 1.77 vs 2.69 operating room visits (P = .008) and 9.88 vs 21.80 therapy days (P = .02), respectively. These inputs plus hospital cost data were used to model costs for the United States, Germany, and the United Kingdom. For the United States, Germany, and United Kingdom, respectively, economic model estimates of total potential per patient savings were $33 338, €8467, and £5626 for negative pressure wound therapy‐instillation group vs control, based on assumed number of OR visits during therapy, cost of therapy system, and length of therapy. Model results showed an overall potential cost‐savings with negative pressure wound therapy‐instillation vs control, based on fewer OR visits and shorter therapy duration as reported in the published systematic review and meta‐analysis.

Abstract
As the use of closed incision negative pressure therapy (ciNPT) becomes more widespread, dressing designs have evolved to address implementation challenges and meet surgeon demand. While traditional application of ciNPT was limited to the immediate suture line, a novel dressing that covers the incision and additional surrounding tissues has become available. To expand upon previous ciNPT recommendations and provide guidance on this new dressing, an expert panel of plastic surgeons convened to review the current literature, identify challenges to the implementation and sustainability of ciNPT, and use a modified Delphi technique to form a consensus on the appropriate use of ciNPT with full‐coverage dressings. After three rounds of collecting expert opinion via the Delphi method, consensus was reached if 80% of the panel agreed upon a statement. This manuscript establishes 10 consensus statements regarding when ciNPT with full‐coverage foam dressings should be considered or recommended in the presence of patient or incision risk factors, effective therapeutic settings and duration, precautions for use, and tools and techniques to support application. The panel also discussed areas of interest for future study of ciNPT with full‐coverage dressings. High‐quality, controlled studies are needed to expand the understanding of the benefits of ciNPT over the incision and surrounding tissues.

Abstract
SUMMARY The multidisciplinary approach to lower extremity function preservation is well established and is globally considered the standard of care. Every member of the team contributes their unique skills and knowledge to patient care. The effective integration of negative-pressure wound therapy with instillation (NPWTi) has fundamentally changed the approach to the infected or contaminated wound. Initially, in conjunction with excisional debridement, NPWTi has demonstrated its utility of expediting wound bed preparation for closure or coverage. With the introduction of a novel foam design, the effectiveness has increased and provided an option in cases where surgical intervention is not available or recommended. The successful implementation and continued monitoring of NPWTi provides an efficient tool to expedite ultimate wound healing and involves all members of the team.

Abstract
SUMMARY The use of negative-pressure wound therapy (NPWT) has become an established therapy for wound management. There have been many advancements in the technology of NPWT including NPWT with instillation and dwell (NPWTi-d). NPWTi-d promotes wound healing by wound cleansing, irrigation, and nonexcisional debridement. NPWTi-d has been shown in comparative clinical studies to decrease the time to definitive wound healing and length of hospitalization. NPWTi-d-using a reticulated open-cell foam dressing with "through" holes (ROCF-CC)-has been postulated to facilitate solubilization, detachment, and elimination of infectious materials, such as slough and thick exudate, before or after operative debridement, and in cases where surgical debridement is not an option. The authors provide an overview on the use of NPWTi-d by reviewing the components of the system, proposed mechanism of action, clinical outcomes, and current consensus guidelines for its utilization.

Abstract
BACKGROUND A promising and useful development of negative-pressure wound therapy (NPWT) is the addition of instillation and dwell time of topical wound solutions (NPWTi-d). Uses of NPWTi-d include acute and traumatic wounds, whereby wound closure may be facilitated via wound cleansing and promotion of granulation tissue formation. This systematic review summarizes publications on NPWTi-d in the treatment of acute and traumatic wounds. METHODS A systematic review was performed analyzing articles from major clinical databases. Only clinical studies ≥10 patients reporting on the application of NPWTi-d in acute and traumatic wounds were included. RESULTS One hundred ninety-two articles were retrieved, of which 10 articles met inclusion criteria. Of those, 2 were lesser-quality randomized controlled trials, comparative studies or prospective cohorts, 2 were retrospective studies, and 6 retrospective cohort studies. In total, included publications reported 109 patients with acute and traumatic wounds treated with NPWTi-d. Data from these studies indicated the potential for reduction in bacterial bioburden through wound cleansing and promotion of granulation tissue formation, thereby facilitating wound closure, reduced length of therapy and hospital time. However, for most publications, different wound causes and subsequently no isolated results for acute and traumatic wounds were reported. CONCLUSION NPWTi-d has promise to be effective in facilitating wound closure and reducing the time for wound closure. The present systematic review demonstrates a relatively low level of evidence available to objectively support this effect. To underline these positive results, large prospective, randomized controlled trials are necessary to manifest the role of NPWTi-d in the daily clinical routine for this wound category.

Abstract
BACKGROUND The addition of topical fluid instillation, a programmable "dwell" time and a novel foam-wound interface to the established wound healing benefits of negative-pressure wound therapy (NPWT) works synergistically to benefit patients with complex wounds. This engineering breakthrough for wound care has been termed NPWT with instillation and dwell (NPWTi-d), and the new foam dressings are reticulated open cell foam dressings specifically designed for use with NPWTi-d. This combined technology has shown promise in chronic, complex wounds and has potential for the management of sacral and ischial pressure wounds. METHODS A qualitative comprehensive review was performed analyzing articles from PubMed and Medline that reported on the use of NPWTi-d in sacral or ischial pressure ulcers. Case series and case reports were predominant, and results of cases specific to sacral and ischial pressure wounds were extracted from larger studies and summarized for presentation. RESULTS Compared with conventional NPWT alone, NPWTi-d has been shown to help irrigate the wound, remove fibrinous debris, and promote granulation tissue formation. This is associated with a decreased number of operative debridements and decreased hospital length of stay. CONCLUSIONS This technology is rapidly demonstrating expanded utilization in hospitalized patients with chronic sacral and ischial pressure ulcers. When used correctly, NPWTi-d serves as an effective "bridge to defined endpoint": whether that is a flap reconstruction, skin grafting, or discharge home with a stable chronic wound and simplified wound care.

Abstract
BACKGROUND Large randomized controlled trials that evaluate the effects of negative-pressure wound therapy with instillation of a topical solution and dwell time (NPWTi-d) are lacking. There is a need to synthesize existing data across multiple studies to provide a more precise estimate of the clinical effects of NPWTi-d. METHODS A systematic literature review and a meta-analysis of comparative studies were performed to determine the effects of NPWTi-d versus control therapy in the adjunctive management of complex wounds. Weighted standardized mean difference or odds ratios and 95% confidence intervals were calculated to pool study and control group results in each publication for analysis. RESULTS Thirteen studies comprising 720 patients were included in the analysis. Significantly fewer surgical debridements were performed in NPWTi-d patients versus control patients (P = 0.01). Wounds in the NPWTi-d group were ready for closure faster than control wounds (P = 0.03). The odds of reducing bacterial count from baseline in the NPWTi-d group was 4.4 times greater than control group wounds (P = 0.003), and percent reduction of bacterial count in NPWTi-d wounds was evident in all studies that captured that endpoint. There was a significantly shorter length of therapy in NPWTi-d patients versus control patients (P = 0.03). Wounds in NPWTi-d group were 2.39 times more likely to close than control group wounds (P = 0.01). Length of hospital stay was not significantly reduced for NPWTi-d patients compared with that for control patients (P = 0.06). CONCLUSION Results of this meta-analysis show a positive effect with use of NPWTi-d in various wound types.

Abstract
This study evaluates the current clinical evidence of Negative Pressure Wound Therapy with Instillation and dwell time (NPWTi‐d) to establish its clinical application and efficacy. MEDLINE, EMBASE, and CENTRAL databases were searched from 1946 to July 2019 for studies reporting clinical outcomes on wounds treated with NPWTi‐d. The primary outcome was proportion of wounds with complete healing. The secondary outcomes were mean time for healing, NPWTi‐d settings, cost, length of stay, and adverse events. Thirteen articles were included with a total of 624 wounds in 542 patients involving wounds of various aetiology. The pooled proportion of wound that achieved complete healing was 93.65% (95%CI: 84.02‐99.04). Normal saline was the most commonly used instillation solution with the mean dwell time of 14.23 minutes (95%CI: 10.88‐17.59) and instillation cycle every 4.17 ± 2.32 hourly. The mean therapy duration was 10.69 days (95%CI: 10.46‐10.91) with daily cost of $194.80. The mean hospital stay was 18.1 days (95%CI: 17.20‐19.00). There were no severe adverse effects reported. NPWTi‐d is an adjuntive therapy to aid complete healing of the vast majority of wounds. However, the current data are limited by the lack of level 1 evidence.

Abstract
Presence of bacteria in wounds can delay healing. Addition of a regularly instilled topical solution over the wound during negative‐pressure wound therapy (NPWT) may reduce bioburden levels compared with standard NPWT alone. We performed a prospective, randomised, multi‐centre, post‐market trial to compare effects of NPWT with instillation and dwell of polyhexamethylene biguanide solution vs NPWT without instillation therapy in wounds requiring operative debridement. Results showed a significantly greater mean decrease in total bacterial counts from time of initial surgical debridement to first dressing change in NPWT plus instillation (n = 69) subjects compared with standard NPWT (n = 63) subjects (−0.18 vs 0.6 log10 CFU/g, respectively). There was no significant difference between the groups in the primary endpoint of required inpatient operating room debridements after initial debridement. Time to readiness for wound closure/coverage, proportion of wounds closed, and incidence of wound complications were similar. NPWT subjects had 3.1 times the risk of re‐hospitalisation compared with NPWT plus instillation subjects. This study provides a basis for exploring research options to understand the impact of NPWT with instillation on wound healing.

Abstract
BACKGROUND Keloids are benign fibro-proliferative lesion, related to excessive inflammatory reactions in certain anatomical areas, including the auricles. Their specific etiology remains unclear; nonetheless they exhibit tumor-like characteristics of significant recurrence and cause emotional distress, even with various treatment strategies. We applied intermittent magnetic pressure therapy on ear keloids in combination with surgical excision, and present its effectiveness herein. METHODS Ear keloid patients were treated with surgical excision followed by magnetic pressure therapy. The keloid tissues underwent excision and keloid marginal flaps were utilized for wound closure. Intermittent magnetic pressure therapy was applied 2 weeks after the surgical procedure. The pressure therapy consisted of a 3-hour application and 2-hour resting protocol (9 hr/day), and lasted for 6 months. The results were analyzed 6 months after the therapeutic procedures, using the scar assessment scale. RESULTS Twenty-two ear keloids from 20 patients were finally reviewed. Among the keloids that completed the therapeutic course, 20 ear keloids out of 22 in total (90.9%) were successfully eradicated. Two patients (2 keloids) exhibited slight under-correction. Postoperative complications such as wound dehiscence or surgical site infection were not noted. The scar assessment scale demonstrated a significant improvement in each index. The intermittent pressure therapy led to patient compliance, and avoided pressure-related pain and discomfort. CONCLUSION Excision followed by intermittent pressure application using a magnet successfully reduced the burden of fibro-proliferative keloids, and had good patient compliance. The role of intermittent pressure application and resting should be studied with regard to keloid tissue remodeling.

Abstract
Autologous breast reconstructions using deep inferior epigastric perforator (DIEP) flaps create a large incision, presenting an opportunity for surgical site complications. In this pilot study, we aimed to examine outcomes in DIEP donor site incisions managed with standard dressings (control; n = 5) or closed incision negative pressure therapy (ciNPT; n = 5). We observed no significant differences between group age, body mass index, and past medical history. Both treatment groups had a similar duration of hospital stay, the number of blood transfusions, and pain scores on postoperative day 2 (P > .05). There was a trend of higher drainage (P = .251) and shorter time to incision healing (P = .067) in the ciNPT group than the control though the difference was not statistically significant. We did observe a significant improvement in scar pigmentation, vascularity, and pliability at 3, 6, and 12 months post-surgery in the ciNPT group compared with control (P < .05). No surgical site complications were reported in the ciNPT group within the follow-up period. In the control group, one patient developed wound edge fat necrosis requiring reoperation. In conclusion, we report that ciNPT is a useful incision management system for DIEP flap donor site incisions and it facilitated improved scar quality over standard dressings in this small pilot study. Further clinical studies are required to assess the full advantages provided by ciNPT.

Abstract
The use of negative pressure wound therapy with instillation and dwell time (NPWTi‐d) has gained wider adoption and interest due in part to the increasing complexity of wounds and patient conditions. Best practices for the use of NPWTi‐d have shifted in recent years based on a growing body of evidence and expanded worldwide experience with the technology. To better guide the use of NPWTi‐d with all dressing and setting configurations, as well as solutions, there is a need to publish updated international consensus guidelines, which were last produced over 6 years ago. An international, multidisciplinary expert panel of clinicians was convened on 22 to 23 February 2019, to assist in developing current recommendations for best practices of the use of NPWTi‐d. Principal aims of the meeting were to update recommendations based on panel members' experience and published results regarding topics such as appropriate application settings, topical wound solution selection, and wound and patient characteristics for the use of NPWTi‐d with various dressing types. The final consensus recommendations were derived based on greater than 80% agreement among the panellists. The guidelines in this publication represent further refinement of the recommended parameters originally established for the use of NPWTi‐d. The authors thank Karen Beach and Ricardo Martinez for their assistance with manuscript preparation.
