The Use of the Vacuum-Assisted Closure in Microsurgical Reconstruction Revisited: Application in the Reconstruction of the Posttraumatic Lower Extremity

Introduction of vacuum-assisted closure (VAC) system into clinical practice has revolutionized wound care. Despite its multiple advantages, however, the VAC is only rarely used in the setting of microsurgical reconstruction. Concerns have been the inability to clinically monitor the flap as well the possibility of flap compression by the device. The authors put their postoperative treatment concept of applying the VAC to free flaps to the test by reviewing their experience with this concept in patients undergoing microsurgical reconstruction of posttraumatic lower-extremity soft tissue defects. Twenty-six patients (22 male, 4 female) were included in this study. Use of the implantable Doppler probe allowed for postoperative flap monitoring. Two flap failures were observed, both in patients with peripheral vascular disease. In conclusion, using the VAC device in the setting of microsurgical reconstruction is safe and allows for increased patient comfort.

The majority of US combat casualty soft-tissue wounds are not infected or colonized upon arrival or during treatment at a continental US military medical facility

Background The microbiology of war wounds has changed as medicine and warfare have evolved. This study was designed to determine the microbial flora and bacterial quantification of present-day war wounds in US troops from Iraq and Afghanistan upon arrival at the National Naval Medical Center (NNMC). Methods Patients with extremity combat wounds treated with a vacuum-assisted wound closure device were enrolled in study. Wounds were biopsied every 48 to 72 hours with quantitative microbiology performed on all biopsies. Results Two hundred forty-two wound biopsies from 34 patients; 167 (69%) showed no growth, and 75 (31%) showed positive growth. The incidence of any bacterial isolation from biopsies weekly from the time of injury was 28% (first), 31% (second), and 37% (≥third). Acinetobacter baumannii was the most prevalent isolate. Conclusions Most soft-tissue wounds from Iraq and Afghanistan do not have significant bacterial burden upon arrival to and during initial treatment at NNMC. Improved evaluation of combat wound microbiology at all levels of care is warranted to determine shifts in microbiology and to impact care practices.

Analysis of Nerve and Neuropeptide Patterns in Vacuum-Assisted Closure–Treated Diabetic Murine Wounds

Reestablishment of the peripheral nervous system occurs in parallel with wound healing. With accelerated wound healing seen with the vacuum-assisted closure device, the authors studied its effects on nerve fiber regeneration, nerve sprouting, and the stimulation of neuropeptides and neurotrophins. A vacuum-assisted closure device was applied to a full-thickness diabetic mouse wound using continuous or cyclical modes and compared with foam dressing or occlusive dressing controls, using 10 mice per group. Nerve fibers, substance P, calcitonin gene-related peptide, and nerve growth factor were analyzed using two-dimensional immunohistochemistry and real-time reverse-transcriptase polymerase chain reaction. A significant increase in dermal and epidermal nerve fiber densities and in substance P, calcitonin gene-related peptide, and nerve growth factor expression was seen in vacuum-assisted closure-treated wounds. Cyclical treatment mode correlated with the largest increase in granulation tissue production, wound surface microdeformations, and a slightly faster wound closure rate. This study suggests that vacuum-assisted closure therapy can modulate nerve fiber and neuropeptide production in the wound. Optimized kinetics of vacuum-assisted closure application may provide an opportunity for clinicians to further improve wound healing in denervated wounds such as pressure sores and diabetic foot ulcerations.

Use of multiple VAC devices in the management of extensive burns: The total body wrap concept

0305-4179/$36.00 # 2010 Elsevier Ltd and ISBI. All rights reserved. doi:10.1016/j.burns.2010.05.007 challenges in modern burn care [1–3]. The heavy fluid output overwhelm most conventional dressings resulting in contamination and increased infection rates [4]. We describe the total body wrap concept: a dressing method that employs multiple VAC (vacuum assisted closure) devices to maintain a clean moist wound environment to enhance graft take while facilitating accurate exudate charting and graft visualisation. Small sponges acting as wicks are placed in dependent areas instead of using large sponges covering the entire wound.

Necrotizing fasciitis following saphenofemoral junction ligation with long saphenous vein stripping: a case report

IntroductionNecrotizing fasciitis is a rare condition with a mortality rate of around 34%. It can be mono- or polymicrobial in origin. Monomicrobial infections are usually due to group A streptococcus and their incidence is on the rise. They normally occur in healthy individuals with a history of trauma, surgery or intravenous drug use. Post-operative necrotizing fasciitis is rare but accounts for 9 to 28% of all necrotizing fasciitis. The incidence of wound infection following saphenofemoral junction ligation and vein stripping is said to be less than 3%, although this complication is probably under-reported. We describe a case of group A streptococcus necrotizing fasciitis following saphenofemoral junction ligation and vein stripping.Case PresentationA 39-year-old woman presented three days following a left sided saphenofemoral junction ligation with long saphenous vein stripping at another institution. She had a three day history of fever, rigors and swelling of the left leg. She was pyrexial and shocked. She had a very tender, swollen left groin and thigh, with a small blister anteriorly and was in acute renal failure. She was prescribed intravenous penicillin and diagnosed with necrotizing fasciitis. She underwent extensive debridement of her left thigh and was commenced on clindamycin and imipenem. Post-operatively, she required ventilatory and inotropic support with continuous veno-venous haemofiltration. An examination 12 hours after surgery showed no requirement for further debridement. A group A streptococcus, sensitive to penicillin, was isolated from the debrided tissue. A vacuum assisted closure device was fitted to the clean thigh wound on day four and split-skin-grafting was performed on day eight. On day 13, a wound inspection revealed that more than 90% of the graft had taken. Antibiotics were stopped on day 20 and she was discharged on day 22.ConclusionNecrotizing fasciitis is a very serious complication for a relatively minor, elective procedure. To the best of our knowledge, this is the first report in the English-language literature of this complication arising from a standard saphenofemoral junction ligation and vein stripping. It highlights the need to be circumspect when offering patients surgery for non-life-threatening conditions.

Vacuum‐assisted closure instill as a method of sterilizing massive venous stasis wounds prior to split thickness skin graft placement

Patients with massive venous stasis ulcers that have very high bacterial burdens represent some of the most difficult wounds to manage. The vacuum-assisted closure (VAC) device is known to optimise wound bed preparation; however, these patients have too high a bacterial burden for simple VAC application to facilitate this function. We present the application of the VAC with instillation of dilute Dakins solution as a way of bacterial eradication in these patients. Five patients with venous stasis ulcers greater than 200 cm(2) that were colonised with greater than 10(5) bacteria were treated with the VAC instill for 10 days with 12.5% Dakins solution, instilled for 10 minutes every hour. Two patients had multi-drug-resistant pseudomonas, three with MRSA. All the five had negative quantitative cultures, prior to split thickness skin graft with 100% take and complete healing at 1 year. Adequate delivery of bactericidal agents to the infected tissue can be very difficult, especially while promoting tissue growth. By providing a single delivery system for a bactericidal agent for a short period of time followed by a growth stimulating therapy, the VAC instill provides a unique combination that appears to maximise wound bed preparation.

A Novel Technique for Lower Extremity Limb Salvage: The Vastus Lateralis Muscle Flap with Concurrent Use of the Vacuum-Assisted Closure Device

Free tissue transfer is an essential component of lower extremity limb reconstruction and has dramatically improved salvage attempts. In this report, we examine the use of the underutilized free vastus lateralis muscle flap and describe our treatment protocol that involves a novel application for the vacuum-assisted closure device in an effort to reduce edema and congestion in lower extremity limb salvage. Thirteen patients underwent reconstruction with 14 vastus lateralis flaps with closure occurring on average 35.2 days after injury and an average case duration of 4:34 days. We report one flap failure, one superficial abscess, and one donor site hematoma. All patients were ambulatory at 6 months. Our early experience using this underutilized flap and novel protocol demonstrate successful lower extremity reconstruction with few complications, and good function and contour. Given its advantages, this versatile flap should be included as an option in lower extremity limb salvage operations.

Vacuum-assisted closure in severe abdominal sepsis with or without retention sutured sequential fascial closure: A clinical trial

Multiple techniques have been introduced to obtain fascial closure for the open abdomen to minimize morbidity and cost of care. We hypothesized that a modification of the vacuum-assisted closure (VAC) technique that provides constant fascial tension and prevents abdominis rectis retraction would facilitate primary fascial closure and reduce morbidity. In all, 53 patients with severe abdominal sepsis were allocated randomly into 2 groups, and 30 patients were analyzed. In the VAC group, we included patients managed only with the VAC device, whereas the retentions sutured sequential fascial closure (RSSFC) group included patients to whom RSSFC was performed. The abdomen was left open for 12 days (P = .0001) with 4.4 ± 1.35 changes per patient for the VAC group (P = .001) and 8 days with 2.87 ± 0.74 dressing changes per patient for the RSSFC group, respectively. Abdominal closure was possible in only 6 patients in the VAC group, whereas for the RSSFC group, abdominal closure was achieved in 14 patients (P = .005). Planned hernia was exclusively decided in patients in the VAC group (P = .001). The hospital stay was 17.53 ± 4.59 days for the VAC group and 11.93 ± 2.05 days for the RSSFC group (P = .0001). The median initial intra-abdominal pressure (IAP) was 12 mm Hg for the VAC group and 16 mm Hg for the RSSFC group (P < .0001). We demonstrated the superiority of RSSFC compared with the single use of the VAC device. In our opinion, sequential fascial closure can immediately begin when abdominal sepsis is controlled.

Melioidosis and the vacuum-assisted closure device: a rare cause of a discharging neck wound, and a new approach to management

We report a case of melioidosis presenting as a discharging neck abscess, and we describe the use of a vacuum-assisted closure device in its management. We report the case of a 44-year-old, Afro-Caribbean woman with melioidosis. We also present the results of a literature search using the search terms 'melioidosis', 'Burkholderia pseudomallei' and 'vacuum-assisted closure device'. Microbiological analysis identified the causative organism as being the bacterium Burkholderia pseudomallei, and its antimicrobial sensitivities to imipenem and ciprofloxacin. A vacuum-assisted closure device was used to manage the patient's melioidosis of the neck; we believe this is the first report of such treatment. Melioidosis is rare in the UK and western world; however, exposure can occur during travel to endemic areas. We therefore draw attention to this infection as part of the differential diagnosis of a neck abscess. We propose the use of vacuum-assisted closure devices as useful adjuncts to the management of discharging neck wounds.

Non-Oral Poster 52

OBJECTIVES: This study aimed to evaluate wound outcomes following the application of negative pressure wound therapy to vulvar wounds resulting from surgical treatment of hidradenitis suppurativa (HS) or Necrotizing Fasciitis MATERIALS AND METHODS: Four patients treated at Thomas Jefferson University Hospital in Philadelphia, PA who underwent radical vulvectomies for HS or Necrotizing Fasciitis with subsequent application of negative pressure wound therapy were identified. Retrospective chart reviews of these four patients were conducted and data was collected regarding their postoperative course. These patients required extensive surgical debridement of the vulvar, perirectal, and buttock area. Following debridement, negative pressure wound therapy was placed. Patients continued to have negative pressure wound therapy dressing changes three times a week for a variable amount of time. Degree of granulation and details of wound healing were documented in patient charts. At Thomas Jefferson University Hospital negative pressure wound therapy was achieved using the Vacuum Assisted Closure Device (VAC) (KCI Inc.; San Antonio, TX). RESULTS: Most case reports on this topic have used the VAC device initially to aid in wound healing; however, complete wound closure was typically achieved using split-thickness skin grafts. Very few case reports have used the VAC device alone to achieve complete closure. Three of the four patients in our series achieved complete closure of their vulvar wounds with the VAC device alone. One patient required closure with a split thickness skin graft after the VAC device was removed. CONCLUSION: Patients with severe Hidradenitis Suppurativa and Necrotizing Fasciitis often require extensive surgical debridement. Data conflict over the optimal methods of management of post-surgical vulvar wounds. Our experience supports good outcome for complete closure of vulvar wounds with negative pressure wound therapy.

Vacuum-assisted closure device in intensive care unit patients and dissemination of Gram-negative bacteria

We read with interest the study by Batacchi and colleagues in a recent issue of Critical Care [1]. Vacuum-assisted closure (VAC) decompression is promising for the management of open abdomen, but our limited experience with this system suggests that dissemination of bacteria may occur. Recently, two patients were treated with VAC in our intensive care unit (ICU). Patient 1 was a 62-year-old man who was originally operated on for paraganglioma and underwent left nephrectomy and gastrojejunal anastomosis. Patient 2 was a 54-year-old woman who was admitted to the ICU two months after a complicated laparoscopic sleeve gastrectomy for morbid obesity. In both patients, at a certain point during their course, intra-abdominal sepsis developed, and they were both managed with extensive debridement, drainage, and VAC placement. Both patients developed fistulas, and although dressings and VAC pump containers were meticulously changed, leaks were repeatedly observed around the dressings. Furthermore, 2 to 4 weeks after the placement of VAC, a rise of positive cultures for Gram-negative bacteria was observed in all patients in our ICU (Figure ​(Figure1).1). As depicted in Figure ​Figure2,2, Klebsiella pneumoniae species became prevalent in our flora despite barrier measures and the isolation of both patients in a separate ward. In 12 out of 34 cases, KPC K. pneumoniae was isolated, whereas in one case it was resistant to all antibiotics. Figure 1 Number of positive Gram-negative and Gram-positive cultures in our intensive care unit during the stay of patients 1 (left) and 2 (right). The arrows represent the time of vacuum-assisted closure placement for each patient. Figure 2 Number of Klebsiella pneumoniae-positive cultures during the stay of patients 1 and 2. The solid arrow represents vacuum-assisted closure (VAC) placement in patient 1. The dotted arrow represents VAC placement in patient 2. Recent literature is inconclusive on this subject. We believe that further studies are needed to confirm the dissemination of bacteria from patients with VAC devices and abdominal leaks.

Short Periodic Applications of the Vacuum-Assisted Closure Device Cause an Extended Tissue Response in the Diabetic Mouse Model

The vacuum-assisted closure device is a widely used mechanical modulator of wound healing; however, the optimal time kinetics of application have not been determined. The objective of the study was to optimize the kinetics of vacuum-assisted closure application. Full-thickness wounds in seven diabetic mice per study group were treated with either an occlusive dressing alone, the vacuum-assisted closure device for 6 or 12 hours, or the vacuum-assisted closure device periodically for 4 hours every other day or continuously for 7 days. Wound closure and tissue response were evaluated by macroscopic, histologic, and immunohistochemical analyses on day 7. Wound closure was significantly faster after short initial vacuum-assisted closure (6-hour and 12-hour groups) when compared with continuous treatment. Increased granulation tissue formation was seen in the 12-hour group (2.4-fold increase) and in those treated periodically for 4 hours every other day (3.2-fold increase) compared with the dressing-alone controls. Significant stimulation of cell proliferation was seen after all vacuum-assisted closure patterns (3.6- to 5.3-fold increase), whereas angiogenesis was augmented only after the device was applied for either three times for 4 hours (4.3-fold) or continuously (4.7-fold) when compared with dressing-treated wounds. Treatment three times for 4 hours showed a superior angiogenic effect also when compared with short initial applications (6-hour and 12-hour groups). Short vacuum-assisted closure treatment induced an extended biological response in the wound. A total of 12 hours of periodically applied vacuum-assisted closure reached a similar wound tissue response as continuously applied vacuum-assisted closure for 7 days. These findings suggest new clinical approaches for mechanical wound-healing devices.

Management of Vascular Graft Infections with Soft Tissue Flap Coverage: Improving Limb Salvage Rates–A Veterans Affairs Experience

Graft infections are one of the most challenging issues in surgery with an incidence of 0.7 to 7 per cent, with femoral site infections being the most common (13% incidence). The gold standard treatment has been graft removal, wide débridement, and extra-anatomical bypass. Routine excision of infected peripheral arterial grafts and vascular reconstruction with extraanatomic conduits are associated with mortality rates ranging from 10 to 30 per cent and amputation rates of up to 70 per cent. As a result of the high morbidity and mortality associated with this approach, selective graft preservation techniques have been developed. Newer treatment plans discuss preservation of the graft with débridement and coverage of the infected region. Better wound care, nutrition optimization, and robust flap coverage have led to significantly improved graft salvage, lower amputation rates, and improved outcomes. The objective of this study was to evaluate the Veterans Affairs (VA) experience with flap coverage for femoral vascular graft infections. A retrospective review was conducted of all VA data from 1997 to 2008 with inclusion criteria of patients with deep groin wound infections requiring flap coverage after femoral bypass surgery. Eleven such patients were identified with a mean age of 73 years and with multiple comorbidities (hypertension, malnutrition, diabetes mellitus, chronic obstructive pulmonary disease, coronary artery disease, chronic renal insufficiency). Patients presented with wound drainage, exposed graft, hematoma, perigraft fluid collection, and pseudoaneurysm. Treatment protocol included: 1) aggressive débridement of the wound bed; 2) early soft tissue (flap) coverage; 3) wound vacuum assisted closure device or frequent dressing changes; and 4) skin graft once the bed was prepared. Eighty-two per cent of wounds had positive cultures with equal numbers of patients with Staphylococcus epidermidis, Pseudomonas, Escherichia coli (22%), and higher methicillin-resistant Staphylococcus aureus (33%), whereas in the literature Staphylococcus is the most common (greater than 50%). Average hospital length of stay was 94 days with average follow up at 10 months. Fifty-five per cent graft salvage (one Dacron [50%], two polytetrafluoroethylene [33%], two saphenous vein graft [100%], one cryovein [100%]) was achieved with 91 per cent limb salvage. Complications included graft blowout (two) requiring partial flap loss (one), retroperitoneal hematoma (one), limb loss (one), sepsis (one), and death (one). Infected vascular grafts remain a challenging problem requiring multidisciplinary care. Careful débridement and aggressive wound care followed by selective flap coverage appears to decrease morbidity and increase graft and limb salvage.

Open abdomen treatment following endovascular repair of ruptured abdominal aortic aneurysms

Open abdomen treatment (OAT) is considered a lifesaving procedure in patients with abdominal compartment syndrome (ACS) after endovascular or open intervention for ruptured abdominal aortic aneurysms (RAAA). Standardized treatment methods and algorithms for its use are still lacking. The high, published mortality rates may reflect difficulties in detecting and treating ACS, especially in patients treated by emergency endovascular aneurysm repair (eEVAR). Presented are standardized algorithms for OAT, including a new technique using the vacuum-assisted closure (VAC) system developed during 10 years of experience with eEVAR for RAAA. We retrospectively analyzed 102 patients with RAAA treated by eEVAR from January 1998 to April 2008. Abdominal decompression was done when intravesical pressure >20 mm Hg or when abdominal perfusion pressure was <50 to 60 mm Hg and concomitant organ deterioration occurred. OAT was initially done with a subcutaneously sutured plastic bag or with a nonsutured zipper drape combined with a VAC device (VAC/ETHIZIP; KCI International Inc, Amstelveen, The Netherlands; Ethicon, Somerville, NJ). All patients were switched to VAC/ETHIZIP as soon as possible. Dressings were generally changed every 3 to 5 days. Intra-abdominal pressure was monitored until stability was observed after delayed direct abdominal closure. Overall 30-day mortality for eEVAR was 13% (13 of 102); 8% (7 of 82) for patients without ACS and 30% (6 of 20) for those with ACS. Decompression for ACS was needed in 20 patients (20%) primarily during the intervention (n = 14) or secondarily in the intensive care unit (n = 6). Six of 20 (30%) patients requiring OAT died <or=30 days (4 primary, 2 secondary). A mean of 3.6 (range, 1-12) planned second-look interventions were done per patient at an interval of 3 to 5 days. No bowel lesions were observed. Four patients required antibiotic therapy for abdominal infection, and all infections resolved. Delayed abdominal wall closure (direct closure, 11; closure with polypropylene mesh, 3; bilateral anterior rectus abdominis sheath turnover flap, 1) was achieved after a median of 6 days (range, 1-47 days). The use of standardized novel techniques and a treatment protocol and algorithm for OAT after eEVAR for RAAA were feasible and safe. It decreased the workload of the medical and nursing staff, enhanced patient comfort because the need for dressing changes was minimized, and likely contributed to lower overall mortality in RAAA patients. Delayed direct fascial closure was possible in most patients.

The use of the artificial dermis (Integra ®) in combination with vacuum assisted closure for reconstruction of an extensive burn scar – A case report

The artificial dermis Integra (Ethicon, Johnson & Johnson Medical, Norderstedt, Germany) is widely used in the treatment of excessive burn injuries. It is also used in reconstructive surgery when large soft-tissue defects could not be covered with local or free flaps. In this article a 25-year old patient who presented with an early childhood burn of the trunk and lower extremity was treated with Integra in combination with the vacuum assisted closure (V.A.C., KCI, Texas, U.S.A.) and split thickness skin grafting. The combination of the artificial dermal substitute with negative pressure therapy has lead to a complete healing of Integra and the skin graft. During the whole treatment sterile wound conditions were present and time-consuming dressing changes could be prevented. Hospital stay was shortened because the patient could be treated as an outpatient with an ambulant vacuum assisted closure device.

Comparison of Fasciotomy Wound Closures Using Traditional Dressing Changes and the Vacuum-Assisted Closure Device

Fasciotomy wounds can be a major contributor to length of stay for patients as well as a difficult reconstructive challenge. Once the compartment pressure has been relieved and stabilized, the wound should be closed as quickly and early as possible to avoid later complications. Skin grafting can lead to morbidity and scarring at both the donor and fasciotomy site. Primary closure results in a more functional and esthetic outcome with less morbidity for the patient, but can often be difficult to achieve secondary to edema, skin retraction, and skin edge necrosis. Our objective was to examine fasciotomy wound outcomes, including time to definitive closure, comparing traditional wet-to-dry dressings, and the vacuum-assisted closure (VAC) device. This retrospective chart review included a consecutive series of patients over a 10-year period. This series included 458 patients who underwent 804 fasciotomies. Of these fasciotomy wounds, 438 received exclusively VAC. dressings, 270 received only normal saline wet-to-dry dressings, and 96 were treated with a combination of both. Of the sample, 408 patients were treated with exclusively VAC therapy or wet-to-dry dressings and 50 patients were treated with a combination of both. In comparing all wounds, there was a statistically significant higher rate of primary closure using the VAC versus traditional wet-to-dry dressings (P < 0.05 for lower extremities and P < 0.03 for upper extremities). The time to primary closure of wounds was shorter in the VAC. group in comparison with the non-VAC group. This study has shown that the use of the VAC for fasciotomy wound closure results in a higher rate of primary closure versus traditional wet-to-dry dressings. In addition, the time to primary closure of wounds or time to skin grafting is shorter when the VAC was employed. The VAC used in the described settings decreases hospitalization time, allows for earlier rehabilitation, and ultimately leads to increased patient satisfaction.

The Vacuum-Assisted Closure (VAC) Device for Hastened Attachment of a Superficial Inferior-Epigastric Flap to Third-Degree Burns on Hand and Fingers

The vacuum-assisted closure (VAC) device has a wide range of clinical applications, including treatment of infected surgical wounds, traumatic wounds, pressure ulcers, wounds with exposed bone and hardware, diabetic foot ulcers, and venous stasis ulcers. Increased release of growth factors has been described, leading to improved vascularization and thereby formation of new tissue. The system is also used in burn surgery for reconstructive purposes. In this case report, a patient suffered from a third-degree burn injury to the dorsum of the hand with exposure of tendons, necessitating the use of a flap reconstruction. The patient was treated with a superficial inferior-epigastric artery-based flap and the VAC system was applied in a created glove-like shape. Hastened attachment of the flap onto the exposed fingers was observed after 4 days. The author reports on the additional use of the VAC system to hasten flap attachment in a patient with a burn injury to the dorsum of the hand.

QS470. The Use of Vacuum-Assisted Closure Device in Neonatal Complex Abdominal Wounds

Vacuum-assisted closure device enhances recovery of critically ill patients following emergency surgical procedures

IntroductionCritically ill surgical patients frequently develop intra-abdominal hypertension (IAH) leading to abdominal compartment syndrome (ACS) with subsequent high mortality. We compared two temporary abdominal closure systems (Bogota bag and vacuum-assisted closure (VAC) device) in intra-abdominal pressure (IAP) control.MethodsThis prospective study with a historical control included 66 patients admitted to a medical and surgical intensive care unit (ICU) of a tertiary care referral center (Careggi Hospital, Florence, Italy) from January 2006 to April 2009. The control group included patients consecutively treated with the Bogota bag (Jan 2006-Oct 2007), whereas the prospective group was comprised of patients treated with a VAC. All patients underwent abdominal decompressive surgery. Groups were compared based upon their IAP, SOFA score, serial arterial lactates, the duration of having their abdomen open, the need for mechanical ventilation (MV) along with length of ICU and hospital stay and mortality. Data were collected from the time of abdominal decompression until the end of pressure monitoring.ResultsThe Bogota and VAC groups were similar with regards to demography, admission diagnosis, severity of illness, and IAH grading. The VAC system was more effective in controlling IAP (P < 0.01) and normalizing serum lactates (P < 0.001) as compared to the Bogota bag during the first 24 hours after surgical decompression. There was no significant difference between the SOFA scores. When compared to the Bogota, the VAC group had a faster abdominal closure time (4.4 vs 6.6 days, P = 0.025), shorter duration of MV (7.1 vs 9.9 days, P = 0.039), decreased ICU length of stay (LOS) (13.3 vs 19.2 days, P = 0.024) and hospital LOS (28.5 vs 34.9 days; P = 0.019). Mortality rate did not differ significantly between the two groups.ConclusionsPatients with abdominal compartment syndrome who were treated with VAC decompression had a faster abdominal closure rate and earlier discharge from the ICU as compared to similar patients treated with the Bogota bag.
