[Central venous catheterization by using ultrasound guidance to patients with terminal stage malignant tumors]

Central venous catheterization with ultrasound guidance was performed on 41 patients with terminal stage malignant tumors--112 consecutive insertions at our hospital. We performed a total of 112 consecutive insertions: 30 with the skin marking method and 82 with the real time echo guidance method. Catheter insertion was performed to the internal jugular vein in 24, the supra-clavicular approach of the subclavian vein in 4, the infra-clavicular approach of the subclavian vein in 37 and the femoral vein in 47. The success rate was 85.7% (96/112 insertions), and the mean insertion time was 2.2 minutes. The complication rate was 4.5%: arterial puncture for 3 insertions, and mal-position for 2 insertions. In this examination, it was confirmed that central venous catheterization with ultrasound guidance could be performed safely and briefly in such patients.
