Continuous or repeated injury of rabbit aortae by indwelling vascular catheters caused the deposition of platelets on the injured vessels and the formation of thrombi rich in platelets and fibrin at sites where flow was most disturbed and injury was most extensive. Incorporation of 51Cr platelets into the thrombi reached a maximum between 3 and 24 hr. The platelet-fibrin-rich thrombi remained r...

The natural history of infective endocarditis (IE) has undergone considerable changes in the antibiotic era. The older classifications of acute, subacute, and chronic have become less meaningful; immunologic phenomena, such as Osler’s nodes and glomerulonephritis, are rarely seen; and nosocomial infections from indwelling catheters and devices are increasing. Early diagnosis and treatment play ...

Urethral catheterization is a common procedure with a relatively low complication rate. Knotting of an indwelling urethral catheter is a very rare complication, and there are only a few case reports on knotted catheters, most of them concerning children. We report an especially rare case where a urethral catheter formed a knot around a double-J ureteral stent after a kidney transplantation. We ...

A frequently debated question for studies involving the measurement of stress hormones in rodents is the optimal method for collecting blood with minimal stress to the animal. Some investigators prefer the implantation of indwelling catheters to allow for frequent sampling. Others argue that the implantation of a catheter creates a chronic stress to the animal that confounds stress hormone meas...

Background: To report the evaluation of incentive spirometry (IS)-induced pressure changes in intra-abdominal drainage catheters and consider its use for maintaining catheter patency enhancing drainage. Methods: Prospective study patients with indwelling abdominal fluid collections who had their pressures measured while performing spirometry. Patients were instructed an spirometer. Within a wee...

Indwelling epidural catheters are frequently used to manage postoperative pain. This report describes a patient who developed methicillin-resistant Staphylococcus aureus (MRSA) vertebral osteomyelitis of the lumbar spine following epidural catheterization. To the best of our knowledge, this is the first reported case of MRSA vertebral osteomyelitis secondary to epidural catheter use in the Engl...
