    The reproducibility of a V.A.C.ℱ (Vacuum Assisted Closure) instillation system was investigated by means of an in vitro model. The relation between the volume of a delivered solution and its removal from the system was studied in foams of various size. The relationship of instillation time periods and the volume of delivered solution was determined.

    Zusammenfassung: Es wird ein Fallbericht ĂŒber ein Entrapment der A.tibialis anterior im Rahmen der Versorgung einer distalen geschlossenen Tibiafraktur mit Hilfe eines Tibianagels prĂ€sentiert. Wegen offenen Metatarsalefrakturen mit einer schwerer Weichteilverletzung der gleichen Seite wurde nach mehreren DĂ©bridements eine freie Latissimus-dorsi-Lappenplastik zur Deckung geplant. Die prĂ€operative Angiographie zeigte einen Verschluss der A.tibials anterior auf Frakturhöhe. Der Verschluss wurde als eine sekundĂ€re GefĂ€ĂŸokklusion interpretiert, die durch eine Intimaverletzung des GefĂ€ĂŸes im Rahmen der Verletzung verursacht wurde. Das Entrapment der Arterie im Frakturspalt wurde erst intraoperativ wĂ€hrend der PrĂ€paration fĂŒr die GefĂ€ĂŸanstomosierung der Lappenplastik festgestell

    Bogota-VAC – A Newly Modified Temporary Abdominal Closure Technique

    Background: We present Bogota-VAC, a newly modified temporary abdominal closure (TAC) technique for open abdomen condition after abdominal compartment syndrome (ACS). Methods: A thin isolation bag (Bogota bag) and a vacuum assisted closure (VAC) system were combined. A matching bag was tension-free fixed on the abdominal fascia by fascia suture. A ring shaped black polyurethane foam of the VAC system was placed into the gap between Bogota bag, abdominal fascia and the wound edge. A constant negative topic pressure of 50–75 mmHg was used in the VAC system. Results: Intra-abdominal pressure (IAP: 22 ± 2 mmHg)of four patients with ACS after severe traumatic brain injury and one patient with isolated ACS after blunt abdominal trauma decreased significantly (p = 0.01)after decompressive laparotomy and treatment with Bogota-VAC (IAP: 10 ± 2 mmHg) and remained low, measured via urinary bladder pressure. Intracranial pressure (ICP) in the four traumatic brain injury patients decreased from 42 ± 13 mmHg to 15 ± 3 mmHg after abdominal decompression. Cerebral perfusion pressure (57 ± 14 mmHg) increased to 74 ± 2 mmHg. Conclusion: The advantage of the presented Bogota-VAC is leak tightness, wound conditioning (soft tissue/fascia), skin protection and facilitation of nursing in combinationwith highest volume reserve capacity (VRC), thus preventing recurrent increased intra-abdominal and intracranial pressure in the initial phase after decompression of ACS compared to other TAC techniques

    Influence of injury pattern on incidence and severity of posttraumatic inflammatory complications in severely injured patients

    BACKGROUND: Severe trauma causes systemic inflammatory response syndrome (SIRS) which may lead to multiple organ dysfunction syndrome (MODS) or multiple organ failure (MOF). The aim of this study was to evaluate the influence of the injury pattern on the incidence and severity of SIRS, sepsis, MODS, and mortality. METHODS: A total of 1,273 patients with an injury severity score (ISS) of ≄ 9 points and survival of more than 3 days were included in this retrospective study. Outcome parameters were various grades of SIRS, sepsis, MODS, and mortality. RESULTS: Severe non-infectious SIRS occurred in 23%, sepsis in 14%, and severe MODS in 14% of the patients. Serious (abbreviated injury scale (AIS) ≄ 3 points) head injury and the ISS represented the most potent risk factors for severe SIRS. As estimated by multivariate logistic regression analysis, the presence of severe extremity and pelvic injuries, the ISS, and the male gender were found to be independent risk factors for sepsis. Severe injuries of the abdomen were associated with an increased risk for sepsis in the univariate analysis. Severe injuries to the head or abdomen, the ISS, and the male gender represented independent risk factors for the development of severe MODS. Regarding the late (> 3 days after trauma) hospital mortality, severe head injury, the ISS, and the patient’s age were independent risk factors. CONCLUSIONS: Head injury predominantly determines the incidence of non-infectious systemic inflammation, MOF, and late hospital mortality of patients with severe trauma. Skeletal or abdominal injuries represent relevant risk factors for septic complications. Thus, the incidence of posttraumatic, life-threatening inflammatory complications is related with certain injury patterns in addition to the gender and the severity of trauma

    Temporary Closure of the Open Abdomen: A Systematic Review on Delayed Primary Fascial Closure in Patients with an Open Abdomen

    Background This study was designed to systematically review the literature to assess which temporary abdominal closure (TAC) technique is associated with the highest delayed primary fascial closure (FC) rate. In some cases of abdominal trauma or infection, edema or packing precludes fascial closure after laparotomy. This "open abdomen'' must then be temporarily closed. However, the FC rate varies between techniques. Methods The Cochrane Register of Controlled Trials, MEDLINE, and EMBASE databases were searched until December 2007. References were checked for additional studies. Search criteria included (synonyms of) "open abdomen,'' "fascial closure,'' "vacuum,'' "reapproximation,'' and "ventral hernia.'' Open abdomen was defined as "the inability to close the abdominal fascia after laparotomy.'' Two reviewers independently extracted data from original articles by using a predefined checklist. Results The search identified 154 abstracts of which 96 were considered relevant. No comparative studies were identified. After reading them, 51 articles, including 57 case series were included. The techniques described were vacuum-assisted closure (VAC; 8 series), vacuum pack (15 series), artificial burr (4 series), Mesh/sheet (16 series), zipper (7 series), silo (3 series), skin closure (2 series), dynamic retention sutures (DRS), and loose packing (1 series each). The highest FC rates were seen in the artificial burr (90%), DRS (85%), and VAC (60%). The lowest mortality rates were seen in the artificial burr (17%), VAC (18%), and DRS (23%). Conclusions These results suggest that the artificial burr and the VAC are associated with the highest FC rates and the lowest mortality rate
