Pressure dressings and postarteriographic care of the femoral puncture site.

Patient dissatisfaction with prolonged bed rest and the discomfort caused by pressure dressings led to the following evaluation. Alternate application of pressure dressings and band-aids to femoral artery puncture sites was performed in 754 arteriographic examinations. The application of pressure dressings for 16-24 hours, especially in hypertensive patients, was found to be justified by a significant reduction in delayed bleeding requiring further medical attention. A minimum application time of 8 hours is supported because all instances of delayed bleeding occurred within 8 hours of the procedure. Arterial thrombosis is not affected by the use of pressure dressings. The rationale for recommendation of bed rest is largely anecdotal and is supported by almost all experienced angiographers responding to our questionnaire.

Bioavailability of a commercial sustained-release quinidine tablet compared to oral quinidine solution.

The bioavailability of quinidine sulfate after oral administration of a commercial sustained-release quinidine tablet was compared with that of oral quinidine sulfate solution in 18 normal subjects. Three hundred milligrams of each product was administered to each subject in standard cross-over fashion on separate occasions, with plasma quinidine levels measured for 46 h after each dose. Although peak plasma quinidine levels were lower, and occurred later, after tablet administration than after solution, analysis of the area under the plasma quinidine level-time curve (AUC) values for each product indicated that the products were equivalent, in terms of the extent of absorption, with the mean AUC (0-46 h) value for the tablet, 8744 . 4 ng x h ml-1, comparable to that of the solution, 9145 . 9 ng x h ml-1.

Laparoscopic feeding jejunostomy: also a simple technique.

Placement of feeding tubes is a common procedure for general surgeons. While the advent of percutaneous endoscopic gastrostomy has changed and improved surgical practice, this technique is contraindicated in many circumstances. In some patients placement of feeding tubes in the stomach may be contraindicated due to the risks of aspiration, gastric paresis, or gastric dysmotility. We describe a technique of laparoscopic jejunostomy tube placement which is easy and effective. It is noteworthy that this method may be used in patients who have had previous abdominal operations, and it has the added advantage of a direct peritoneal view of the viscera. We suggest that qualified laparoscopic surgeons learn the technique of laparoscopic jejunostomy.
