BACKGROUND Clinical benefits of thoracic epidural anesthesia (TEA) are partly ascribed to thoracic sympathetic block. However, data regarding sympathetic activity during TEA are scarce and contradictory. This prospective, randomized, double-blind study evaluated the segmental propagation of sympathetic block after low-concentration, high-volume TEA using(More)
Fentanyl is an opioid initially developed for parenteral administration. While oral administration is not an option due to a high first-pass metabolism, its high potency and lipophilicity have made a number of new routes of administration feasible. The transdermal therapeutic system offers an excellent option for long-term treatment of cancer and chronic(More)
BACKGROUND Acute pancreatitis has been linked to intestinal barrier dysfunction and systemic inflammatory response with high mortality. Thoracic epidural analgesia improves intestinal perfusion. The authors hypothesized that thoracic epidural analgesia influences microcirculation injury, inflammatory response, and outcome of acute pancreatitis in rats. (More)
Microcirculatory dysfunction contributes significantly to tissue hypoxia and multiple organ failure in sepsis. Ischemia of the gut and intestinal hypoxia are especially relevant for the evolution of sepsis because the mucosal barrier function may be impaired, leading to translocation of bacteria and toxins. Because sympathetic blockade enhances intestinal(More)
This study assessed modulation of hypoxic pulmonary vasoconstriction (HPV) in isolated perfused rat lungs during sepsis induced by cecal ligation and perforation (CLP) at different times and its relationship to nitric oxide synthases (NOS). Prospective controlled trial in a university research laboratory. 102 male Sprague-Dawley rats. Groups 1–3 received(More)
Fluid resuscitation in sepsis-related lung injury is limited by aggravation of pulmonary edema. Hypovolemia, however, may compromise tissue perfusion and contribute to organ dysfunction. We hypothesized that inhaled nitric oxide would reduce edema formation during fluid therapy. Prospective laboratory investigation in a university research laboratory(More)
The goal of this work is to derive four-voice music pieces from given musical plans, which describe the harmonic flow and the intentions of a desired composition. We developed the experimentation platform COMPOzE for intention-based composition. COMPOzE is based on constraint programming over finite domains of integers. We argue that constraint programming(More)
A is caused by autoantibodies to coagulation factor VIII (FVIII). Preoperative diagnosis is impaired by the lack of a personal or family history of bleeding episodes. Th erefore, surgical procedures can lead to life-threatening hemorrhage [1]. We present a case of a 72-year-old woman who had no history of coagulopathy and who was undergoing hys-tero scopy(More)
Relapsing polychondritis is characterized by recurrent inflammation of the cartilaginous tissues of the ears, nose, peripheral joints, and the tracheobronchial tree. The eye is also a frequent target organ in relapsing polychondritis, and proptosis is a well-recognized manifestation of eye involvement. Similar to other rheumatologic diseases, an association(More)
BACKGROUND AND OBJECTIVE Sevoflurane has been shown to distinctly reduce bronchial mucus transport velocity, an essential determinant of mucociliary clearance and pulmonary complications. However, sevoflurane is regarded as one of the least irritant volatile anaesthetics, especially when compared with desflurane. Hence, the aim of this double-blind,(More)
