Acute respiratory distress syndrome is characterized by damage to the lung caused by various insults, including ventilation itself, and tidal hyperinflation can lead to ventilator induced lung injury (VILI). We investigated the effects of a low tidal volume (V T) strategy (V T ≈ 3 ml/kg/predicted body weight [PBW]) using pumpless extracorporeal lung assist(More)
Die extrakorporale Membranoxygenierung (ECMO) stellt heute im Rahmen klinischer Algorithmen einen wichtigen Baustein in der Therapie des schweren akuten Lungenversagens (ARDS) dar, nachdem sich in observationellen Studien der Wert dieses Verfahrens für die ARDS-Therapie trotz fehlender positiver kontrollierter Studien gezeigt hat. In spezialisierten Zentren(More)
BACKGROUND Survivors of acute respiratory distress syndrome exhibit neuropsychological sequelae that might be attributable to hippocampal damage. The authors sought to determine the effects of hypoxemia in a pig model of acute lung injury on the hippocampal region and the release of S-100 protein in comparison to a control group in which hypoxemia was(More)
BACKGROUND In acute lung injury, ventilation avoiding tidal hyperinflation and tidal recruitment has been proposed to prevent ventilator-associated lung injury. Information about dynamic recruitment may be obtained from the characteristics of pressure-volume (PV) curves or the profile of pressure-time (Paw-t) curves. METHODS Six anesthetized pigs with(More)
Lung protective ventilation in acute lung injury (ALI) focuses on using low tidal volumes and adequate levels of positive end-expiratory pressure (PEEP). Identifying optimal pressure is difficult because pressure-volume (PV) relations differ regionally. Precise analysis demands local measurements of pressures and related alveolar morphologies. In a porcine(More)
BACKGROUND The mechanisms by which partial liquid ventilation (PLV) can improve gas exchange in acute lung injury are still unclear. Therefore, we examined the time- and dose-dependency of the improvements in arterial oxygen tension (PaO2) due to PLV in eight pigs with experimental lung injury, in order to discriminate increases due to oxygen dissolved in(More)
Repair of giant incisional hernias may lead to an increase in intra-abdominal pressure (IAP) and, sometimes, to abdominal compartment syndrome. Measurement of IAP using Kron’s technique (Kron et al. in Ann Surg 199:28–30, 1984) is currently accepted as the gold standard, whereas Harrahill has described a simple measurement setup using urinary drainage(More)
Objective. To compare ventilation-perfusion (VA/Q) distributions during improvement of oxygenation caused by high-frequency oscillatory ventilation (HFOV) and pressure-controlled mechanical ventilation with high PEEP levels (CMV) in experimental acute lung injury (ALI). Design. Prospective, controlled animal study. Setting. Animal research facility of a(More)
In most severe cases of the acute respiratory distress syndrome, veno-venous extracorporeal membrane oxygenation (ECMO) can be used to facilitate gas exchange. However, the clinical use is limited due to the size and the concomitant risk of severe adverse events of conventionally-used centrifugal blood pumps with high extracorporeal blood volumes. The(More)
INTRODUCTION Atelectasis is a common finding in acute lung injury, leading to increased shunt and hypoxemia. Current treatment strategies aim to recruit alveoli for gas exchange. Improvement in oxygenation is commonly used to detect recruitment, although the assumption that gas exchange parameters adequately represent the mechanical process of alveolar(More)
