A method of vascular catheterization is presented in which small polyvinyl catheters are introduced into peripheral vessels through 18 to 21 gage needles and then advanced into the central vascular bed. This technic has been utilized in the study of hemodynamic events occurring in the central arterial vessels in man. The results obtained from 31 arterial catheterizations done in 21 subjects are...

We critically assessed studies on the clinical importance, diagnosis, incidence, and pathogenesis of peripheral vein infusion thrombophlebitis, including catheter-related and patient-related risk factors. We reviewed the evidence linking thrombosis, particularly prothrombotic states such as the inherited thrombophilic disorders, with peripheral vein infusion thrombophlebitis. Peripheral vein in...

A prospective study of 2,209 intravenous catheters was performed in a multidisciplinary intensive care unit to determine when and why catheters were removed and which sites of insertion were associated with the least morbidity. Techniques of insertion were vigorously supervised. Central and peripheral catheters were cared for by identical protocols. Overt phlebitis or inflammation around the si...

BACKGROUND Central venous catheters are commonly inserted for hemodynamic monitoring, volume monitoring, administration of medications, long-term total parenteral nutrition, access for renal replacement therapy, cardiopulmonary resuscitation, and difficult peripheral catheterization. The primary outcome of this study was to define venipuncture, catheterization and entire procedure success rates...

11 Extremely low birth weight neonates who developed skin discoloration after peripheral arterial catheterization were given intra-arterial papaverine before the removal of arterial line. The skin color turned normal in all these neonates and none developed residual damage. In 3 neonates who could not receive papaverine, one developed gangrene of fingers.

T HE RECORDING of concentration-time curves at a peripheral arterial site following injection of an indicator into the heart and great vessels provides a valuable tool for the study of normal and abnormal circulation. Its increasing use in diagnostic and research laboratories attests to its efficacy. When this technic is used, it is desirable to have a normal standard of reference with which th...

The constant (C= 3I) in the hydraulicformulafor calculation of mitral valve area was originally empirically determined by comparison of measured valve area at operation or necropsy with right heart catheterization data. This constant corrects, among other things, for overestimation of the diastolic filling and mitral valve gradient derived from a peripheral arterial tracing and pulmonary capill...

Apseudoaneurysm (PSA) is a contained rupture; there is a disruption in all 3 layers of the arterial wall (Figure 1). PSAs may occur under 4 circumstances: (1) after catheterization (Figure 2); (2) at the site of native artery and synthetic graft anastomosis (eg, aortofemoral bypass graft); (3) trauma; and (4) infection (eg, mycotic PSA) (Figure 3). This review will focus on PSAs that occur afte...
