Comment: "I'm still convinced that this is talking about venous/vein catheterization/cannulation, but what Susana suggested is perfectly possible for the context, I think, but not quite what I was looking for.

Catheter (cannula) selection for catheterization (cannulation) depends on the goals of therapy and attributes of the catheter. The most efficient method for administering large volumes of fluid (eg, after trauma, during surgery) is the insertion of two or more short, wide-bore (<= 16 gauge) peripheral catheters. In contrast, patients needing secure or continuous vascular access (eg, for administration of antibiotics, chemotherapy, or parenteral hyperalimentation) are better treated with long, small-bore central venous catheters (central venous lines--CVLs). http://www.merck.com/pubs/mmanual/section16/chapter198/198c.htm Canalización de una vía venosa, preferentemente central (Drum) para control de la PVC, si no esposible canalizar una vía periférica. http://www.geocities.com/HotSprings/Villa/1585/eap.htm Central catheters allow solutions to be infused with less potential for complications (eg, venous thrombosis, local tissue necrosis); hemodynamic monitoring of central venous, pulmonary artery, and pulmonary capillary wedge pressures (see below); and estimation of cardiac output and peripheral or pulmonary vascular resistance. Central venous pressure (CVP) determinations also help monitor volume status. A CVL can also provide hemodynamic data in cardiac tamponade or pulmonary embolism.
