1. Brzezinski M, Luisetti T, London MJ. Radial artery cannulation: a comprehensive review of recent anatomic and physiologic investigations. Anesth Analg. 2009;109(6):1763–81. Consistent anatomic accessibility, ease of cannulation, and a low rate of complications have made the radial artery the preferred site for arterial cannulation. Radial artery catheterization is a relatively safe procedure with an incidence of permanent ischemic complications of 0.09%.

2. Chaparro Mendoza K. Radial artery catheterism for invasive monitoring: Preventing complications, a challenge in anesthesia. Rev Colomb Anestesiol. 2012;40(4):262–5. Permanent ischemic hand injuries have been reported to occur in 0.09% of cases. A current theory is that an embolic phenomenon that compromises colateral circulation or the digital arteries could be the cause of distal ischemia and residual injuries in surgical interventions. In case this complication appeared, the catheter should be removed and patients with symptomatic vasospasm and thrombosis should be treated with vasodilation and anticoagulation therapy.

Intensive Care Med. 2008;34:339–43. The use of heparinized solution for arterial catheter maintenance does not seem to be justified as it did not increase the duration of the catheters, nor did it improve their functionality significantly. On the other hand, heparin Na altered aPTT significantly.

CHEST J. 2016;149(1):166–79. The use of dynamic 2-D ultrasound guidance for radial artery catheterization decreases first-attempt failure, mean attempts to success, mean time to success, and the occurrence of hematoma complications. Dynamic 2-D ultrasound guidance is recommended as an adjunct to aid radial arterial catheterization.

5. Hoste EA, Roels NR, Decruyenaere JM, Colardyn FA. Significant increase of activated partial thromboplastin time by heparinization of the radial artery catheter flush solution with a closed arterial catheter system. Crit Care Med. 2002;30:1030–4. A heparinized flush solution for the arterial catheter, when used together with a closed-loop blood sampling system, leads to erroneous results of heparin-sensitive coagulation studies.
