Central venous catheterization in infants and children with congenital heart diseases: experiences with 500 consecutive catheter placements.
In a prospective study results of central venous catheter (CVC) placements in a consecutive group of 500 patients with less than 20 kg body weight undergoing cardiac surgery were evaluated. The incidence of previous cardiac surgery was 21% and the incidence of factors preventing the primary puncture of the right jugular or innominate vein was 13.4%. The anesthesiologists were free to select the catheterization technique, site of puncture, and catheter type. All CVC insertions were performed prior to surgery under continuous circulatory monitoring and optimal positioning of the anesthetized patient. Ninety-six percent of all catheterizations were successful, 81% of them on the first attempt. In the 4% of cases where catheterization failed, a CVC had to be placed by the surgeon. Of all catheters, 66% were positioned via the right internal jugular (IJV) or innominate vein (IV), 8% via the left, 16% via an external jugular vein (EJV), and 5% via other veins. Seventy-six percent of CVC insertions were performed with the Seldinger technique. Of the four catheter types used in this study, double lumen catheters were most frequently selected (38%). Placement of 22-ga single lumen catheters was preferred in infants with less than 5 kg body weight, in spite of their tendency to kink. Observed complications (10% arterial puncture, 4% hematoma, and 1% intrathoracic bleeding) never required immediate surgical intervention. Careful selection of appropriate catheters, as well as extensive experience and knowledge of the anatomical structures involved in special heart defects, helped to keep the risk of complications low.
