Key result
Pre-bypass systolic pressures were greater in the radial artery than in the subclavian artery in men undergoing coronary artery surgery.
Why the study?
Does radial artery pressure differ from subclavian artery pressure in men undergoing coronary artery surgery?

Does radial artery pressure differ from subclavian artery pressure in men undergoing coronary artery surgery?
Radial artery systolic pressures are greater than subclavian artery pressures pre-bypass during coronary artery surgery.
Radial artery systolic pressures may overestimate central values pre-bypass; leaves open clinical relevance in coronary surgery.
Radial artery and subclavian artery pressures were measured in nine men undergoing coronary artery surgery requiring cardiopulmonary bypass. Radial artery pressures were measured simultaneously through short (10.2 cm) and long (106.9 cm) tubing using two transducers in a branched tubing system. Interaction between the branches was minimal in an in vitro test system. The radial artery pressures were compared with simultaneous subclavian artery pressures measured through a catheter introduced into the axillary artery. Pre-bypass, the systolic pressures were greater in the radial than in the subclavian artery (P

Bazaral et al. (1988) conducted an observational in Coronary artery surgery requiring cardiopulmonary bypass (n=9). Radial artery pressure measurement vs. Subclavian artery pressure measurement was evaluated on Systolic pressures pre-bypass. Pre-bypass systolic pressures were greater in the radial artery than in the subclavian artery in men undergoing coronary artery surgery.
