Endoscopic ultrasonography of the lower esophagus was performed in 25 patients with reflux esophagitis and 13 age-matched controls. Thickening of the esophageal wall and abnormalities of its architecture were detected. As these morphological changes became more extensive, the lower esophageal sphincter pressure and the decrease of sphincter pressure on(More)
The effects of intravenous nicardipine on the neuromuscular blockade produced by single bolus injection of vecuronium were studied in surgical patients undergoing tracheal intubation. We measured the mechanical response of the abductor pollicis muscle to stimulation of the ulnar nerve in a train-of-four sequence at 2 Hz and recorded the amplitudes of the(More)
The straight leg raising test is one of the most reliable test for the diagnosis of the disc herniation. It is well known that the pain is produced by the increased tension of the affected root. However, the patient's response to the pain evoked by the straight leg raising test is not uniform. In some patients the leg is raised beyond the straight leg(More)
The changes in EMG evoked by train-of-four (TOF) stimulation of ulnar nerve were recorded to determine proper single bolus dose of vecuronium for endotracheal intubation in surgical patients. Onset and duration of neuromuscular block were judged by percent depression of EMG. Mean time intervals for 90% depression in TOF seen in 0.10 mg.kg-1 vecuronium group(More)
Background:Focused assessment with sonography for trauma(FAST)is useful for detecting hemoperitoneum (HE) in trauma patients in the emergency room (ER), but, patients’condition cannot be evaluated adequately by FAST alone. CT is useful for the diagnosis of multiple trauma,but has certain drawbacks. We evaluated the utility of mutidetector computed(More)
