CONTEXT In congenital hyperinsulinism (CHI), the identification and precise localization of a focal lesion is essential for successful surgery. OBJECTIVE Our objective was to evaluate the predictive value and accuracy of integrated [18F]fluoro-L-DOPA ([18F]FDOPA) positron emission tomography (PET)-computed tomography (CT) for the surgical therapy of CHI.(More)
BACKGROUND Intraoperative stress may suppress the adaptive immune system. Abolished proinflammatory lymphocyte function is associated with higher risk of infection and postoperative complications. We hypothesized that thoracic epidural anaesthesia (TEA) reduces intraoperative stress and thus attenuates lymphocyte decrease and impairment of proinflammatory(More)
The pharmacokinetics of opioids are impaired in patients with liver and renal failure. Fentanyl, sufentanil, and alfentanil are metabolized in the liver. The extrahepatic metabolism by renal enzymes is gaining more importance in patients with severe liver disease. Pharmacokinetic effects of single doses of fentanyl and sufentanil are not affected in liver(More)
Percutaneous central venous cannulation of small infants is a challenging procedure. The use of ultrasound guidance has been shown to increase the success rate generally in children and to decrease the incidence of associated complications. To demonstrate that this technique is also suitable in very small infants we describe the case of a preterm neonate of(More)
BACKGROUND This study investigates whether long-term treatment with an angiotensin converting enzyme inhibitor (ACEI) impairs the hemodynamic regulation during the early phase of spinal anaesthesia. METHODS Forty-two patients undergoing minor surgery were studied. Twenty-one patients were long-term treated (ACEI group), while the other patients served as(More)
Acute hypoxia causes hyperventilation and respiratory alkalosis, often combined with increased diuresis and sodium, potassium, and bicarbonate excretion. With a low sodium intake, the excretion of the anion bicarbonate may be limited by the lower excretion rate of the cation sodium through activated sodium-retaining mechanisms. This study investigates(More)
This study investigated whether adenosine mediates the decrease in plasma renin activity (PRA) during acute hypoxia. Eight chronically tracheotomized, conscious beagle dogs were kept under standardized environmental conditions and received a low-sodium diet (0.5 body wt(-1).day(-1)). During the experiments, the dogs were breathing spontaneously via(More)
BACKGROUND Combination of epidural and general anesthesia (combined anesthesia) avoids the intraoperative use of intravenous analgesics and may reduce the surgical stress response during major abdominal surgery. This study examines the differences in intraoperative hemodynamic stability, cortisol levels and activity of cardiovascular hormones between(More)
AIM This study investigates angiotensin II and endothelin-1 mediated mechanisms involved in the haemodynamic, hormonal, and renal response towards acute hypotensive haemorrhage. METHODS Conscious dogs were pre-treated with angiotensin II type 1 (AT1) and/or endothelin-A (ETA) receptor blockers or not. Protocol 1: After a 60-min baseline period, 25% of the(More)
Die Pharmakokinetik der in Anästhesie und Intensivmedizin verwendeten Opioide ist bei eingeschränkter Leber- und Nierenfunktion verändert. Fentanyl, Sufentanil, Alfentanil und Piritramid unterliegen der hepatischen Metabolisierung, ihre extrahepatische Metabolisierung ist bei Leberfunktionsstörung bedeutsam. Nach Einzeldosen von Fentanyl und Sufentanil ist(More)
