A comparison of the efficacy of heparinized and nonheparinized solutions for maintenance of perioperative radial arterial catheter patency and subsequent occlusion . In a randomized , double-blind , controlled study , we compared heparinized and nonheparinized infusions for the maintenance of perioperative arterial catheter patency and the incidence of subsequent radial arterial occlusion . Two-hundred patients were randomized into 2 groups to receive heparinized ( group H , n = 100 ) or nonheparinized ( group S , n = 100 ) flush solutions . Radial and ulnar blood flows were assessed using Doppler probe and pulse oximetry before , just after , and 24 h after decannulation by the same investigator . The cannulation site was examined for complications such as hematoma , nerve injury , and infection . The mean duration of cannulations was 378 +/- 159.0 min in group H and 332 +/- 154.6 min in group S. The mean number of corrective interventions caused by dampening of the pressure wave ( mean number of positional changes [ group S , 1.5 +/- 2.0 ; group H , 1.4 +/- 3.8 ] and mean number of manual flushes [ group S , 1.3 +/- 1.7 ; group H , 1.2 +/- 1.2 ] ) was not significantly different in both groups . After decannulation , partial or total occlusion developed in 20 group H patients and 16 group S patients ( not significant ) . The incidence of occlusion was correlated to the presence of hematoma at the puncture site after decannulation ( P = 0.013 ) , long duration of cannulation ( P = 0.04 ) , and age < 65 yr ( P = 0.009 ) . In conclusion , there is no significant difference between heparinized and nonheparinized flush solutions for the maintenance of perioperative radial artery catheter patency .
