Radial arterial catheters in children and neonates: A prospective study
561
Abstracts
oximetry v arterial blood gasesin measuring oxygen saturation in 21 infants. Ten patients were under the age of seven days with acute cardiorespiratory disease, and 11 were older than 28 days with chronic lung disease. There was good correlation between the two methods over a wide range of saturation values in the chronic lung disease patients. Calculated PaOzfrom pulse oximetry was within 10 Torr of measured Pa4 in 73% of the chronic patients but in only 50% of the acute patients. Correcting for the higher proportion of fetal hemoglobin in the acute patients did not increase the correlation. The authors conclude that pulse oximetry correlates well with the PaOrin infants with chronic lung conditions, but is of less reliability in those with an acute cardiorespiratory problem. [Alan F.

H, Nilsson K, Larsson LE, Ekstromjodal B. Crit Care Med 1987; 15:1106-1109. This prospective, nonrandomized study measured the complication rate of radial artery catheters in children and neonates and compared two methods of maintaining catheter patency: continuous heparin flush intermittent heparin flush. Four hundred seventy-sixpatients (including 296 under the age of 1 year) were treated using #20gauge radial artery catheters and intermittent flushes of heparin. The life span of these catheters was 2.6 days, with minimal complications occurring in 8%. The reason for catheter removal was usually catheter malfunction. A second group of 39 patients under the age of 1 year was treated with similar catheters but using continuous heparin flush. This group had no complications with a mean duration catheter life of 6.3 days with a decreased proportion of catheter malfunction and increased proportion of removals due to no further need of use. The authors conclude that radial artery catheterization is a safe method in children and neonates with the use of continuous heparin Bush increasing the life span of the catheter. [Alan F. Chou, MD]
