Respiratory management for patients with a giant bulla during anesthesia should avoid positive-pressure ventilation to reduce the risk of barotraumas. We report a case of anesthetic management of a 42-year-old man with a giant bulla who had an elective surgery for biopsy of a tumor on his left elbow. Balanced anesthesia consisting of general anesthesia was(More)
Actions of trapidil on mechanical and electrical activities of rabbit right atria were investigated in vitro. Isolated atria had spontaneous contractions. Ca++ (2.7-4.5 mM) concentration-dependently increased force and frequency of atrial contractions, and trapidil (10(-5)-10(-4) g/ml) also did. Trapidil (10(-5)-10(-4) g/ml) showed a tendency to augment the(More)
WHAT IS KNOWN AND OBJECTIVE Calcium channel blockers (CCBs), which have been widely used for the treatment of hypertension and angina pectoris, decrease lower oesophageal sphincter pressure and, as a result, can exacerbate gastrointestinal disease. In a previous study, increased risk of exacerbation of gastrointestinal disease among elderly patients(More)
Possible antiarrhythmic activities of 5-methyl-7-diethylamino-s-triazolo(1,5-a)pyrimidine (trapidil, Rocornal) were investigated in vitro and in vivo. Trapidil significantly increased the amount of aconitine or ouabain needed for production of ventricular arrhythmias in rats and guinea pigs. Trapidil also produced a significant increase in threshold current(More)
