[Difficult catheterization of the radial artery. Comparison of a new arterial catheter and Seldinger's technic].
Sixty difficult radial artery cannulations were carried out using either the Seldinger technique (Seldicath Plastimed, FG 3, 80 mm long; group S; n = 30) or a new arterial catheter (Arrow, Critikon, gauge 20, 44 mm long; group A; n = 30) in patients scheduled for coronary arterial surgery or cardiac valve replacement (age: 54.8 +/- 11.8 yr). The technique was chosen at random after failure of radial artery catheterization with a short intravenous catheter (Quick-Cath Travenol, gauge 20, 31 or 51 mm long, or Insite W Beckton-Dickinson, gauge, 20, 30 mm long). The second attempt was carried out on the same artery, a few centimeters higher up than the first one. Heparinized normal saline was infused through this arterial line. All the catheters were removed after extubation. There was no arterial thrombosis, nor any displacement of the catheter with loss of the arterial pressure curve. No difference was found between the two techniques regarding the number of catheterization failures, the duration of cannulation, and the quality of the blood pressure curve. For difficult radial artery cannulations, the arterial catheter Arrow associated the advantages of the Seldinger technique with those of short intravenous catheters.
