Discussion/General Information |
The management and treatment of chronic wounds, including pressure ulcers, remains a challenge. Most chronic wounds will heal only if the underlying cause, such as venous stasis, pressure, or infection, is addressed. In addition, cleaning the wound to remove non-viable tissue, microorganisms and foreign bodies is essential to create optimal conditions for either re-epithelialization or preparation for wound closure with skin grafts or flaps. Debridement, irrigation, whirlpool treatments and wet to dry dressings are common components of chronic wound care.
Vacuum assisted wound therapy is an adjunct to the basic principles of wound care described above. This technique involves applying initial continuous and subsequent intermittent topical negative pressure to an entire wound. The action removes excess fluid from the interstitial space of the wound, thereby enhancing vascular perfusion through vessels compressed by the excess fluid pressure. Additionally, it is believed that removal of excess fluid removes an accumulation of healing-inhibitory factors. Finally, mechanical stretching results in deformation of cellular bridges, which increases cellular proliferation, protein synthesis, and granulation tissue. The net result is accelerated wound closure by re-epithelialization or preparation for wound closure with suturing, skin grafts or flaps (delayed primary intention).
Currently available vacuum assisted wound therapy devices all have some combination of attributes which are used to differentiate them from each other. These attributes include being stationary vs. portable, being operated electrically vs. mechanically, and being reusable or disposable. Stationary devices are usually large and plug into an electrical socket for power. They are intended to be used either in the hospital or some other location where the individual being treated is not very mobile. Newly available portable devices weigh less and are intended for treatment of clinically stable individuals who are mobile. Some devices may operate electrically and others via a mechanical mechanism (for example, being spring loaded) to create the necessary vacuum for treatment. The vast majority of devices available currently are electrically operated. Finally, there are reusable vs. disposable devices. Available stationary devices are all reusable and used in conjunction with disposable items like bandages and tubing. Disposable devices are usually entirely disposable, and no portion of the devices is reused or saved.
NPWT is generally accepted for use in the outpatient setting for the select treatment of wounds, including pressure ulcers, neuropathic ulcers, ulcers related to venous or arterial insufficiency, dehisced wounds, post-sternotomy wounds, and surgically created wounds requiring accelerated granulation therapy, when a complete wound care program has been attempted, and no absolute contraindications to vacuum assisted wound therapy exist. Available evidence supporting the use of traditional electric NPWT systems includes multiple reasonably designed and conducted trials demonstrating a benefit with regard to decreased infection, complication rates, or some parameter of wound healing when compared to standard care (Armstrong, 2005; Blume, 2008; Canaino, 2005; Costa, 2018; De Franzo, 2001; Doss, 2002; Eginton, 2003; Gupta, 2017; Seidel, 2020; Smid, 2017; Stannard, 2009; Stannard, 2012). Additionally, a number of case series have reported supportive data (Baillot, 2010; Ford, 2002; Garner, 2001; Hersh, 2001; Moisidis, 2004; Moues, 2004; O’Connor, 2005). When clinically appropriate, vacuum assisted wound therapy may also be applied using battery powered portable devices. A number of studies evaluating battery powered NPWT have demonstrated a benefit with regard to decreased infection and complication rates when compared to standard of care for skin grafts, surgical wounds, traumatic wounds, and diabetic leg ulcers (Carrano, 2021; Gabriel, 2013; Hudson, 2013; Kirsner, 2019 and 2021; León Arellano, 2021; Pellino, 2013 and 2014; Peterson, 2021 Selvaggi, 2014). The use of NPWT in pediatric populations has also been addressed in multiple studies (Baharestani, 2007; Caniano, 2005; Chen, 2017; Gabriel, 2009; Li, 2013; Mouës, 2007; Petkar, 2011; Visser, 2017; Yang 2017). Evidence also shows that the use of NPWT in pediatric populations results in an improvement in wound healing, and that age appears to have no impact on treatment outcomes.
Mechanically powered vacuum assisted wound therapy devices, also referred to as ultraportable vacuum therapy systems, utilize specialized springs to create the vacuum needed for negative pressure wound therapy. Available data addressing this type of mechanically powered vacuum assisted wound therapy include several studies showing improved healing of neuropathic or venous stasis ulcers (Fong, 2010; Lerman, 2010). Other trials have demonstrated non-inferiority to standard NPWT devices for the treatment of lower extremity diabetic or venous stasis ulcers (Armstrong, 2011; Armstrong, 2012; Bradbury, 2015; Marston, 2015). Cuomo and others (2017) evaluated the use of NANOVA™ Therapy System (KCI USA, Inc. San Antonio, TX) for the treatment of 10 individuals with chronic venous leg ulcers undergoing skin grafting. The device was well tolerated and contributed to successful engraftment after 14 days for 8 individuals, with 2 individuals requiring additional time for healing. Cuomo and colleagues (2021) performed a three part comparative analysis for ultraportable negative pressure wound therapy devices. The first phase evaluated the specifications of each device included in the study; the second phase enrolled 125 individuals with venous leg ulcers, traumatic wounds, diabetic ulcers, surgical wound diastases, and arteriopatic ulcers. The third phase was a systematic review on classic and portable negative pressure wound devices. This study evaluated the advantages and disadvantages of each device and did not compare wound-healing statistics since the wounds were not homogenous. The conclusion of this study is that each wound is unique and a variety of devices allows the wound care treatment team options for the optimal match for successful healing.
Traumatic Wounds
Additional outpatient uses for NPWT have been evaluated for a variety of wounds such as traumatic wounds from dog bites and routine prophylactic use in postoperative settings (that is: for surgically created wounds without complications, where accelerated granulation therapy is not necessary or can be achieved by other available topical wound treatment). Rui-Feng and others (2016) published the results of a randomized controlled trial (RCT) investigating NPWT for serious dog bite wounds; this study found that infection rates were decreased for individuals treated with NPWT compared to sterile dressings (4.0% versus 9.1%, respectively). Due to a lack of additional credible published evidence, NPWT for the use in serious dog bite wounds is not a generally accepted standard of practice. Routine prophylactic NPWT for postoperative care has been evaluated by a number of studies; however, many studies exhibit methodological flaws, including lack of standardized definitions for reporting adverse events or inclusion criteria, publication biases, heterogeneity due to wide ranges of surgical procedures evaluated, and short follow-up (Cagney 2020; Curran, 2019; Fleming, 2018; Galiano, 2018; Gombert, 2020; Hyldig, 2019; Kenney, 2019; Saunders, 2021; Shiroky, 2020; Strugala; 2017; Zwanenburg 2020). Overall evidence for the effectiveness of NPWT on post-operative wound healing compared to standard care remains uncertain (Costa, 2020; De Vries, 2016; De Vries, 2017; Flynn, 2019; Higuera-Rueda, 2021; Karlakki, 2016; Kuo, 2021; Meyer, 2020; O’Neill, 2020; Sexton, 2020; Tuuli, 2020). Norman and colleagues (2020) published the results of a Cochrane systematic review and concluded with moderate-certainty evidence that prophylactic NPWT reduced surgical site infections, however there was low-certainty evidence for the reduction of deaths or wound dehiscence. In addition, the evidence was low or very low for other secondary outcomes evaluated.
Prophylactic NPWT
Bueno-Lledó (2021) published the results of an unblinded single-site RCT involving 146 subjects undergoing surgical repair of inguinal hernia treated with either prophylactic NPWT (n=72) or standard care (n=74). The authors reported that at 30 days there was significantly higher incidence of overall surgical site adverse events, in the control group vs. to the NPWT group (29.8% vs 16.6%, p<0.042), a result mainly driven by a significantly higher surgical site infection occurrence (SSO) rate in the control group vs. the NPWT group (0 vs. 6 cases, p<0.002). There was no difference in postoperative seroma, hematoma, or dehiscence between groups, or difference in hospital length of stay. While the results are promising, they are not widely generalizable given the low power of the trial, the lack of blinding and other methodological factors. The authors conclude that “more prospective studies […] are needed to effectively evaluate advanced wound care technologies and novel NPWT dressings, which are purported to provide additional benefits to reduce the incidence of SSOs.”
Cooper (2022) investigated the use of NPWT in an RCT involving 120 subjects with previously identified risk factors for surgical site complications who underwent direct anterior approach to total hip arthroplasty (n=60 in each group). Overall, surgical site complications were reported in 13.3% of subjects, with 18.3% in control subjects vs. 8.3% NPWT subjects (p=0.107). The majority of the subjects with surgical site complications (9.2% of the overall cohort) also met CDC criteria for superficial surgical site infections, with 9 (15.0%) control group subjects and 2 (3.3%) NPWT subjects (p=0.027). No differences between groups were reported with regard to wound dehiscence (p=0.11), seep surgical site infection (p=0.50), or prolonged drainage (p=0.12).
Svensson-Björk (2022) reported on an RCT investigating the impact of NPWT on surgical site infections in 377 subjects who underwent endovascular aneurysm repair and postoperative treatment with NPWT (n=183) or standard care (n=194) with the primary intent of fascia closure. Bilateral incisions were done in 223 subjects and unilateral incisions were done in 52 subjects. At 90 days post-procedure no significant differences between groups were reported with regard to surgical site infection (p=0.18 in the cohort with bilateral incisions and p=1.0 in those with unilateral incisions). At 1 year similar results were reported (p=0.29 and p=1.0, respectively). The authors concluded that NPWT provided no benefit with regard to surgical site infection post endovascular aneurysm repair.
Lopez-Lopez (2023) reported the results of the PONILITRANS study, a RCT involving 108 subjects who underwent liver transplantation procedures were assigned to postoperative treatment with either prophylactic incisional NPWT (n=54) or standard surgical dressing (n=54). The overall rate of surgical wound infection in the entire study population was 10.2%, with 13% in the control group and 7.4% in the NPWT group (p=034). Furthermore, significant difference between groups was reported with regard to rate of surgical wound-related events (p=0.83), wound hematoma rates (p=0.65), or dehiscence rate (p=0.65). The authors concluded, “The prophylactic use of negative pressure wound therapy on primarily closed incisions did not significantly reduce incisional surgical site infection and surgical site event rates after liver transplantation compared with standard surgical dressings.”
Kaçmaz (2023) reported on an RCT involving 50 subjects who underwent colorectal surgery and received post-operative treatment with either prophylactic NPWT (n=24) or standard wound care (n=26). Overall, at the 3 month endpoint 16.7% of subjects in the NPWT group developed surgical site infections vs. 53.8% of control group subjects (p=006). Additionally, the incidence of seroma was significantly greater in the control group (8.3% vs 34.6%, p=0.025). No differences in median length of stay between groups were reported (p=0.153), and no hematomas or wound dehiscence/evisceration were noted. The authors concluded, “This study confirmed that pNPWT effectively helps prevent SWCs in high-risk wounds after open CRC surgery.”
Sapci (2023) reported on a similar trial investigating the impact of NPWT on superficial surgical site infections in high-risk, open, reoperative, colorectal surgery. A total of 298 subjects were included (149 in each group). Contrary to the findings of the Kaçmaz study, at 30-days post-surgery the superficial surgical site infection rate was not significantly different between groups (14.1% for controls vs. 9.4% for NPWT; p=0.28). Additionally, no differences between groups were found in 7-day superficial (p=0.28), deep (p>0.99), organ-space (p=0.62) surgical site infections rate, or Clavien-Dindo grade of 30-day postoperative complications (p=0.23) or rates of wound dehiscence (p=0.62). Length of hospital stay was comparable between the groups (6 days vs. 7 day, p=0.78). The authors concluded, “Incisional negative pressure wound therapy was not associated with reduced superficial surgical site infection or overall complication rates in patients undergoing high-risk reoperative colorectal resections”
Ceppa (2023) also reported on an RTC involving 138 subjects undergoing major elective colorectal or hepatopancreatobiliary surgery and receiving postoperative treatment with either NPWT (n=63) or standard of care (n=75). The authors reported no difference between the groups with regard to proportion of subjects with surgical site infections (14% of the NPWT group vs. 17% of the control group, p=0.31). Additionally, there were no significant differences between the groups with regard to superficial incisional infections (9% vs. 11%, p=not reported), deep incisional infections (8% vs. 3%, p=not reported) or organ or space infections (13% vs. 11%, p=0.35). No differences between groups were reported with regard to length of hospital stay (p=0.06) or readmission within 30 days (p=0.77). The authors concluded there was no benefit found for NPWT individuals undergoing major elective colorectal or hepatopancreatobiliary surgery.
Gonzalez (2023) published the results of a RCT trial involving 154 individuals undergoing cesarean delivery treated with standard dressing (n=75) or NPWT (n=79). Follow up documentation was gathered 138 of the individuals. Wound complication was reported in 19.4% of the standard dressing group and 19.7% in the NPWT group (p= 0.43). Wound infection was reported in 9% of the standard dressing group and 7% in the NPWT group (p=0.70). At the time of caesarean delivery, the authors found no difference in the rate of wound complications between women who were treated with NPWT and those who were given standard pressure dressings.
Lindholm (2024) reported on an RCT involving 20 individuals who underwent ambulatory full-thickness skin graft reconstruction for lower limb skin cancer treated with conventional dressing (n=10) or NPWT (n=10). Both groups showed equal adhesion of grafts (p = 0.47), with 80% of the grafts treated with NPWT and 100% of the grafts with conventional dressing demonstrating over 90% adhesion to living tissue in one week. Within a span of three months postoperatively, there was no notable difference (p=0.65) in the rate of wound complications between either group. In the NPWT group, 70% of patients encountered a complication or delayed wound healing, where the wound was still open three weeks postoperatively, compared to 50% in the conventional dressing group. The authors noted the NPWT device did not appear to lower the risk of complications for lower limb full thickness skin graft. In fact, it might have potentially heightened the risk for graft necrosis. The authors noted this is an area that warrants further research and assessment.
Despite a number of published studies and meta-analysis evaluating use of prophylactic NPWT for postoperative indications, the conflicting outcomes reported data does not support routine use or prophylactic NPWT at this time.
Contraindications
While NPWT is generally safe and well tolerated, complications can include bleeding, infection, pain, and organ damage. Complications are more likely to occur when NPWT is applied to individuals with contraindications to vacuum assisted wound therapy, such as exposed vital structures (for example, organs, blood vessels, vascular grafts), malignancy in the wound, necrotic tissue with eschar, non-enteric and unexplored fistulas, or untreated osteomyelitis.
Authoritative Organization Recommendations
In 2016 the Society for Vascular Surgery, the American Podiatric Medical Association, and the Society for Vascular Medicine released joint recommendations related to the management of diabetic foot wounds (Hingorani, 2016). In this document, they provide the following recommendation: “We suggest the use of negative pressure wound therapy for chronic diabetic foot wounds that do not demonstrate expected healing progression with standard or advanced wound dressings after 4 to 8 weeks of therapy (Grade 2B).”
Definitions |
Dehisced wounds: A condition where a wound has a premature opening or splitting along natural or surgical suture lines due to improper healing.
Eschar: A dry scab that forms on skin that has been burned or exposed to corrosive agents.
Group 2 or 3 support surfaces: Two groups within the three classifications of specialized pressure reducing bed types available as a preventive measure for bedsores. The classification system is as follows:
Group 1 - Pressure reducing mattress overlays. These overlays may be filled with air, water, foam or gel and are intended for placement over a standard mattress
Group 2 - Special mattresses alone or fully integrated into a bed. These mattresses may be filled with air, water, foam or gel and are intended as a replacement for a standard mattress
Group 3 - Air Fluidized Beds. These are devices that employ the circulation of filtered air through silicone coated ceramic beads that create the characteristics of fluid, creating a sensation of floating
Mediastinitis: A condition characterized by inflammation of the cavity that holds the heart and other organs.
Neuropathic ulcer: An ulcer resulting from the loss of sensation (i.e., pain, touch, stretch) as well as protective reflexes, due to loss of nerve supply to a body part.
Post sternotomy: The period of time immediately following any surgery where the sternum or breastbone is opened to gain access to the chest cavity.
Pressure ulcer (National Pressure Injury Advisory Panel, 2019): A pressure injury is localized damage to the skin and/or underlying soft tissue usually over a bony prominence or related to a medical or other device. The injury can present as intact skin or an open ulcer and may be painful. The injury occurs as a result of intense and/or prolonged pressure or pressure in combination with shear. The tolerance of soft tissue for pressure and shear may also be affected by microclimate, nutrition, perfusion, co-morbidities and condition of the soft tissue.
Pressure ulcer stages:
Pressure Injury:
A pressure injury is localized damage to the skin and/or underlying soft tissue usually over a bony prominence or related to a medical or other device. The injury can present as intact skin or an open ulcer and may be painful. The injury occurs as a result of intense and/or prolonged pressure or pressure in combination with shear. The tolerance of soft tissue for pressure and shear may also be affected by microclimate, nutrition, perfusion, co-morbidities and condition of the soft tissue.
Stage 1 Pressure Injury: Non-blanchable erythema of intact skin
Intact skin with a localized area of non-blanchable erythema, which may appear differently in darkly pigmented skin. Presence of blanchable erythema or changes in sensation, temperature, or firmness may precede visual changes. Color changes do not include purple or maroon discoloration; these may indicate deep tissue pressure injury.
Stage 2 Pressure Injury: Partial-thickness skin loss with exposed dermis
Partial-thickness loss of skin with exposed dermis. The wound bed is viable, pink or red, moist, and may also present as an intact or ruptured serum-filled blister. Adipose (fat) is not visible and deeper tissues are not visible. Granulation tissue, slough and eschar are not present. These injuries commonly result from adverse microclimate and shear in the skin over the pelvis and shear in the heel. This stage should not be used to describe moisture associated skin damage (MASD) including incontinence associated dermatitis (IAD), intertriginous dermatitis (ITD), medical adhesive related skin injury (MARSI), or traumatic wounds (skin tears, burns, abrasions).
Stage 3 Pressure Injury: Full-thickness skin loss
Full-thickness loss of skin, in which adipose (fat) is visible in the ulcer and granulation tissue and epibole (rolled wound edges) are often present. Slough and/or eschar may be visible. The depth of tissue damage varies by anatomical location; areas of significant adiposity can develop deep wounds. Undermining and tunneling may occur. Fascia, muscle, tendon, ligament, cartilage and/or bone are not exposed. If slough or eschar obscures the extent of tissue loss this is an Unstageable Pressure Injury.
Stage 4 Pressure Injury: Full-thickness skin and tissue loss
Full-thickness skin and tissue loss with exposed or directly palpable fascia, muscle, tendon, ligament, cartilage or bone in the ulcer. Slough and/or eschar may be visible. Epibole (rolled edges), undermining and/or tunneling often occur. Depth varies by anatomical location. If slough or eschar obscures the extent of tissue loss this is an Unstageable Pressure Injury.
Unstageable Pressure Injury: Obscured full-thickness skin and tissue loss
Full-thickness skin and tissue loss in which the extent of tissue damage within the ulcer cannot be confirmed because it is obscured by slough or eschar. If slough or eschar is removed, a Stage 3 or Stage 4 pressure injury will be revealed. Stable eschar (i.e., dry, adherent, intact without erythema or fluctuance) on an ischemic limb or the heel(s) should not be removed.
Deep Tissue Pressure Injury:
Persistent non-blanchable deep red, maroon or purple discoloration. Intact or non-intact skin with localized area of persistent non-blanchable deep red, maroon, purple discoloration or epidermal separation revealing a dark wound bed or blood filled blister. Pain and temperature change often precede skin color changes. Discoloration may appear differently in darkly pigmented skin. This injury results from intense and/or prolonged pressure and shear forces at the bone-muscle interface. The wound may evolve rapidly to reveal the actual extent of tissue injury, or may resolve without tissue loss. If necrotic tissue, subcutaneous tissue, granulation tissue, fascia, muscle or other underlying structures are visible, this indicates a full thickness pressure injury (unstageable, Stage 3 or Stage 4). Do not use DTPI to describe vascular, traumatic, neuropathic, or dermatologic conditions.
Medical Device Related Pressure Injury:
This describes an etiology. Medical device related pressure injuries result from the use of devices designed and applied for diagnostic or therapeutic purposes. The resultant pressure injury generally conforms to the pattern or shape of the device. The injury should be staged using the staging system.
Mucosal Membrane Pressure Injury:
Mucosal membrane pressure injury is found on mucous membranes with a history of a medical device in use at the location of the injury. Due to the anatomy of the tissue these injuries cannot be staged.
Vacuum assisted wound therapy: A type of medical therapy that involves the use of suction (negative pressure) underneath airtight wound dressings to promote the healing of open wounds that have resisted previous treatments.
