arterialize

The method of arterialization was almost exclusively heel warming, usually by immersing the heel in warm water (40[degrees]C to 45[degrees]C) for five to 10 minutes prior to heel stab, or using a warmed surgical-plastic device.18 The rather cumbersome method of histamine iontophoresis was used to arterialize capillary blood of neonates in one early study.(15) Finger stab was the preferred site for sampling capillary blood from children.(17), (19)

Our group of vascular surgeons is of the opinion that it takes approximately four weeks to arterialize the vein that has been selected to create the arteriovenous fistula.

The hand was placed for 15 min under water at 41 to 43[degrees]C to arterialize blood samples (7).

It was observed that these veins have thin wall and are difficult to arterialize. Some patients had patent veins for three months.

The subject's hand and wrist was kept in a hot air box maintained at 55-60[degrees]C throughout the trial to arterialize the blood as previously described [24].
