Prolonged access to the venous system using the Hickman right atrial catheter.

Seventy-one Hickman catheters were inserted into 63 patients for prolonged access to the venous system. The mean catheter life was 98 days, but despite the long life in situ provided by these catheters only 5 (7%) had to be removed for septic complications. The technique of insertion is described and the subsequent management of these catheters discussed. The management of patients receiving parental nutrition, those undergoing bone marrow transplantation for acute leukaemia, and those having cytotoxic chemotherapy was greatly facilitated by the use of the catheter.

Effect of pancreatic polypeptide on gallbladder pressure and hepatic bile secretion.

Intraluminal gallbladder pressure, measured by radiotelemetry, and bile output were monitored during infusion of porcine pancreatic polypeptide (PP) at doses of 6, 25, 100, and 400 pmol . kg-1 . h-1 in healthy conscious pigs. Plasma PP concentrations during infusion of the three lower doses, measured by radioimmunoassay, were within the range seen postprandially in these animals. Gallbladder pressure fell in a dose-related manner during PP infusion by 2.2 +/- 0.9, 8.2 +/- 0.4, 11.6 +/- 0.7, and 14.8 +/- 0.8 mmHg, respectively. In addition, a significant reduction in the bile output was observed during infusion of the two higher doses of PP. In a separate series of experiments, using cholecystectomized pigs, PP had no effect on bile output. These findings suggest that the amount of PP released postprandially may be sufficient to influence gallbladder function but not hepatic secretion of bile in the pig.

The ultrasonic demonstration of portacaval shunts.

This study explores the use of ultrasound in the management of patients with portacaval anastomosis. Ten patients were studied; in 8 of these the status of the anastomosis was well demonstrated. It is suggested that ultrasound should be the initial investigation to determine the patency of a shunt.
