Twenty-four-hour episodic secretion of cortisol was studied in patients with chronic alcoholic liver disease in order to define how and if feedback inhibition of the hypothalamic-pituitary-adrenocortical axis had occurred. The patients had prolonged disappearance rates of endogenous cortisol and corticosteroid-binding globulin-binding capacity was low.(More)
The response to iv dexamehasone was studied in patients with chronic renal failure in whom resistance to suppression of plasma cortisol levels after oral steroid had been reported previously. One milligram of dexamethasone was given iv at 2300 h, and plasma cortisol levels were measured every 20 min between 0500-1000h in patients with renal failure, normal(More)

A 52-year-old woman, ASA II (American Society of Anesthesia classification II) scheduled for cholecystectomy in an ambulatory center, exhibited a wide-complex tachycardia with ectopy on the monitor after induction with propofol and succinylcholine. Blood pressure remained stable; amiodarone was administered for presumed ventricular tachycardia. A 12-lead(More)
The effect of prophylactic heparinization on the postoperative venous blood flow was prospectively studied in 100 lower limbs of 50 patients. Patients were randomized into two groups of 25 patients each: a control group and a heparin group. Changes in the venous blood flow were monitored using the Doppler ultrasonic flowmeter. The study illustrated the(More)
