Abstract

Purpose: In spite of the importance of central venous routes for many therapies, cutdown and catheterization are sometimes difficult. We present child cases inserted with 3.6 Fr Silascon O type catheters or 7 Fr Hickman dual lumen catheters, reporting the patient's background, the rate of success and the cause of failure. Methods: We made 133 central venous routes in patient from neonates to 15-year-old children for 4 years. We utilized anesthesia for cutdown, and x-ray to confirm the placement of the catheter tip in the operation room. Results: We managed 57 malignant cases, 41 gastrointestinal cases and 37 intensive care cases. 3.6 Fr Silascon venous catheters were used in 39 cases, and 7 Fr Hickman dual lumen catheters in 98 cases. Of 133 first catheterizations for central venous routes, 129 cases were successful. Of 4 second catheterizations, all 4 cases were successful. The causes of failure in the first catheterization were misleading of the Hickman catheter's tips in the right external jugular vein of an 8-year-old patient and in the left external jugular vein of a 10-year-old patient. In addition, the Hickman catheter was too large to ingent into the left cephalic vein of a 6-year-old patient. Moreover, The Silascon catheter was not inserted through the right external jugular vein of an 8-year-old child because of occlusion. Conclusions: All catheters could be inserted in neonates and infants because it was easy to distend their veins and change their direction. The reasons why the central venous accesses were difficult were intravenous thrombus, direction of vein of bifurcation for large catheters, and the thickness of veins except the external jugular vein.
