Problems commonly encountered include obstruction of the femoral vein by the catheter insertion difficulties safety concerns when cannulating the subclavian vein in coagulopathy and catheter and circuit occlusion due to disseminated intravascular coagulation. For access in infants we describe a technique utilizing two single-lumen thin-walled vascular sheaths. For infants and small children initial access to the vein may be difficult due to edema or poor perfusion. For this situation we describe the miniintroducer technique of securing the vein and facilitating subsequent insertion of a relatively large guide wire. At any age an alternative route to the subclavian vein from above the clavicle is potentially compressible in the event of hemorrhage during the procedure. We remind the reader of the utility of ultrasound guidance for cannulation of the internal jugular and subclavian veins. And lastly we review the options for venous return via the umbilical vein in infants and via .
