STUDY OBJECTIVE We sought to describe the epidemiology of emergency department (ED) patients with blunt head injury undergoing cranial computed tomography (CT) scanning for the evaluation of possible traumatic brain injury (TBI). METHODS Prospective, multicenter, observational study of ED patients undergoing cranial CT after blunt head injury. Patient's(More)
OBJECTIVE Paroxysmal supraventricular tachycardia (SVT) is a common dysrhythmia treated in the prehospital setting. Emergency medical service (EMS) agencies typically require patients treated for SVT to be transported to the hospital. This retrospective cohort study evaluated the impact, paramedic adherence, and patient re-presentation rates of a(More)
Intracellular recordings of spontaneous and evoked end-plate potentials have been made at the neuromuscular junction of mouse hemidiaphragms to determine a possible role of cyclic AMP (cAMP) in the release of acetylcholine from presynaptic terminals. Spontaneous release, as determined from the frequency of miniature end-plate potentials, was increased by(More)
Experiments on rabbits showed that intravenous injection of dyestuffs of the thionine series (toluidine blue, azur A, 1:9 dimethylene blue) was accompanied by hypofibrinogenemia, a decrease in the concentration of prothrombin complex factors, thrombocytopenia and the lowering of the blood platelets adhesion against the background of delayed blood(More)
Experiments on rabbits showed that intravenous injection of dyes of the thionine series (toluidine blue, azure A, 1,9-dimethylmethylene blue) causes hypofibrinogenemia, a decrease in the concentration of factors of the prothrombin complex, thrombocytopenia, and a decrease in the index of platelet adhesion against the background of slowing of the time of(More)
