Late perforation by central venous cannulae.
Three cases of hydrothorax secondary to late perforation of the superior vena cava by central venous cannulae are presented. The care of central venous cannulae is discussed.
متن کاملThe Need of Slanted Side Holes for Venous Cannulae
Well-designed cannulae must allow good flow rate and minimize nonphysiologic load. Venous cannulae generally have side holes to prevent the rupture of blood vessel during perfusion. Optimizing side hole angle will yield more efficient and safe venous cannulae. A numerical modeling was used to study the effect of the angle (0°-45°) and number (0-12) of side holes on the performance of cannulae. ...
متن کاملHigh-flow Nasal Cannulae in Very Preterm Infants after Extubation
BACKGROUND The use of high-flow nasal cannulae is an increasingly popular alternative to nasal continuous positive airway pressure (CPAP) for noninvasive respiratory support of very preterm infants (gestational age, <32 weeks) after extubation. However, data on the efficacy or safety of such cannulae in this population are lacking. METHODS In this multicenter, randomized, noninferiority trial...
متن کاملVenous flow velocity, venous volume and arterial blood flow.
The relationship of arterial blood flow and venous volume to venous flow velocity was studied in normal subjects. The effects of current modes of treatment in venous thrombosis and of a vasodilator drug on venous flow velocity were also investigated. Total calf flow and venous volume were measured by venous occlusion plethysmography while venous flow axial velocity was determined by the transit...
متن کاملA single-center experience with luminal venous cannulae obstruction caused by clot formation during bypass.
Our institution experienced two bypass cases from January through December 2011 in which venous return was significantly variable and at times poor. Luminal clot formation in the venous cannulae was found in each case postbypass. These events were captured and monitored through our institution's Non-Routine Event Reporting Program and eventually reported to the Food and Drug Administration (FDA...
