Clinical Application of Two kinds of Central Vein Catheterization in Hemodialysis

Objective To explore and find the safe and effective method of central vein catheterization for hemodialysis patients.Methods We analyzed 245 hemodialysis patients using central vein catheterization retrospectively.171 internal jugular venous catheterizations and 74 femoral venous catheterization were included in the study.Two methods were performed:blind catheterization in 169 cases and catheterization by color Doppler ultrasonography guidance in 76 cases.Complications and management of the two methods were analyzed with P0.05.Results In the 169 cases using blind catheterization,complications included misplacement into arteries in 6(3.6%),local hematoma in 4(2.4%),local bleeding in 3(1.8%),misplacement into thoracic duct1(0.6%),pneumothorax in 1(0.6%).No complications were found in 76 cases by color Doppler ultrasonography guidance.Conclusion Catheterization by color Doppler ultrasonography guidance is a safe and effective method.
