In an attempt to restore functional surfactant to the lungs of patients with the adult respiratory distress syndrome (ARDS), we have treated six patients within the first 2 days of the onset of ARDS with a single dose of hydrophobic components of porcine surfactant. Surfactant (4 g in 50 ml) delivered via a bronchoscope in aliquots to each of the lobar(More)
Administration of exogenous lung surfactant to infants with or at risk for respiratory distress syndrome has been demonstrated to improve gas exchange and survival; administration of surfactant to patients with the adult respiratory distress syndrome is currently undergoing clinical evaluation. Although it is currently assumed the optimal effect will occur(More)
Exogenous surfactant therapy has been recognised as an approach to alleviating the surfactant-deficine state for 3 decades. Natural and lipid-extracted surfactants derived from amniotic fluid, lung lavage, or lung homogenates are being used in worldwide clinical trials in premature infants. These studies are demonstrating a generally favourable influence on(More)
We have tested the hypothesis that oxidation of lung surfactant results in loss of surface tension lowering function. Porcine lung surfactant was exposed to conditions known to cause lipid peroxidation (0.2 mM FeCl2 + 0.1 mM H2O2 or 5 microM CuCl2). Lipid peroxidation was verified by detection of conjugated dienes, thiobarbituric acid reactive substances,(More)
ABSTRACT: Previous studies in preterm lambs have shown that exogenous surfactant is more uniformly distributed if given at birth before ventilation or if followed by high-frequency ventilation (HFV) after establishing conventional ventilation (CV). We hypothesized that the preterm rabbit pup would respond similarly and that improved respiratory system(More)
The effect of exogenous surfactant in the treatment of acute lung injury may depend on homogeneity of distribution of the material delivered. Analyses of distribution rely on sectioning the lung, determining surfactant concentration for each piece, and describing the variation in that value. Results of such analyses are influenced by how finely the lung is(More)
Studies of the metabolism and distribution of lung surfactant are aided by use of radiolabeled surfactant or surfactant components. These studies have often made use of [3H]- or [14C]phosphatidylcholine. Analysis of the lung content of surfactant containing these beta-emitting labels usually requires tissue digestion, use of scintillation fluids, and(More)
Zeichen von denjenigen ohne intraoperativer Wachheit unterscheiden [5]. Die isolierte Vorderarmtechnik ist zwar für einzelne kurzdauernde Eingriffe von wissenschaftlichem Interesse, ist aber nicht in der breiten klinischen Anästhesietätigkeit anwendbar. Der Bispektrale Index (BIS) ist einfach anwendbar und zuverlässig im Quantifizieren der Sedation mit(More)
