The CF is a biocompatible puncture cannula composed by an internal metal needle intended to AVF puncture and an external fluroplastic catheter (15G) that remains inside the arterialized
Immediately before and two minutes after, every other training session, each subject undertook fingertip' arterialized
[La-] and [H+] from a superficial heated hand vein was measured at baseline.
The feeding artery will demonstrate a high-velocity, low-resistance waveform and the draining vein may show pulsatile, arterialized
A technique for ultrasound-guided puncture of an arterialized
extracranial venous pouch with transosseous microcatheter navigation through a mastoid emissary vein (MEV) is described.
At 0630 h after an overnight fast of 10 h, an intravenous catheter (Jelco, 22G, Medex Medical Ltd, Lancashire, UK) was inserted, under sterile precautions, into the antecubital vein for infusion of insulin and 25 per cent dextrose solutions, while another catheter was inserted in an anti-flow direction into the dorsal vein of the contra lateral hand for arterialized
blood sampling (using a warm box into which the hand was placed, maintained between 60 and 65[degrees]C).
Hunt, et al, (15) simultaneously collected arterialized
(by histamine iontophoresis) and non-arterialized
capillary samples from each study subject for comparison with arterial blood and found no difference in pH, pC[O.
Further, 8 minutes after the exercise was completed, an arterialized
fingertip blood sample was taken and lactate was measured.
Therefore, the mixed venous blood flowing to these gas exchange units does not become arterialized
because no ventilation is present to provide for oxygen uptake and carbon dioxide excretion.
Current patient care is based on measurement of glucose in venous blood or arterialized
sinusoids, lined by CD34-positive endothelial cells, may be equivalent to "capillarization," as described by Schaffner and Popper and others.
Supplemental blood flow can also be delivered by connecting the perfusion side limb of the Rivetti-Levinson(R) IntraLuminal Shunt to any source of arterialized
blood using a standard Luer connection.
