Incidence of forearm and hand ischaemia related to radial artery cannulation in newborn infants.
We report the incidence of transient and permanent ischaemia of the forearm and hand caused by radial artery cannulation in a series of 98 newborn infants. Birth weight ranged from 550 to 3920 g (median 1600 g) and gestational age ranged from 26 to 40 weeks (median 31 weeks). In 4 of the 98 infants transient ischaemia of the forearm and/or hand occurred. In three infants the onset of ischaemia was probably related to thrombo-embolic events and in one infant to inadequate palmar collateral circulation. Permanent ischaemic damage with tissue loss did not occur in any infant. It is concluded that permanent ischaemic damage to the forearm and/or the hand with tissue loss, attributable to radial artery cannulation, is seldom encountered in newborn infants. In minimizing the risk of ischaemia, careful assessment of palmar collateral circulation prior to cannulation and of all factors predisposing to the onset of ischaemia is essential. Immediate removal of the catheter at the earliest signs of ischaemia, is essential to prevent ensuing tissue loss.
