Abstract

Background & Objectives:Catheterization of Internal Jugular Vein (IJV) is commonly attempted to obtain central venous access for hemodynamic monitoring, long term administration of fluids and inotropes, chemotherapeutic agents or corrosive drugs as well as total parenteral nutrition and hemodialysis in critical care patients. The catheterization of the IJV can be achieved by either anatomical landmark technique or the Ultrasound (USG) guided technique. The objective of our study is to find out if USG guided technique could be beneficial in placing central venous catheters by improving the success rate by reducing the number of attempts, decreasing the access time and decreasing the complications rate in comparison to the Landmark technique. Materials & Methods: Fifty patients scheduled for cardiac surgery requiring central venous cannulation of the right IJV were divided into two groups: USG guided group ‘U’ and the landmark guided group ‘L’, each consisting of 25 patients with age more than 15 years. The outcome measures were compared between the two groups in terms of success rate, time taken for successful cannulation and rate of complications. Results: The two groups were comparable in terms of age, weight, heart rate and blood pressure. The mean number of attempts for successful cannulation was 1.08±0.277 and 1.40±0.764 (p=0.055), the time taken in seconds for successful cannulation was 108.56±27.822 and 132.08±72.529 (p=0.137) and the overall complication rate was 0% (0 out of 25) and 32% (8 out of 25) (p=0.002) in the USG guided and the landmark technique group respectively. Conclusion: Our study has found that the use of USG in central venous cannulation of the internal jugular vein requires similar number of attempts and almost similar time for successful cannulation with that of the landmark technique. However the overall complications rate is markedly decreased by the use of USG than by the landmark technique for the central venous cannulation. Hence, we conclude that USG guided technique is much safer than the landmark technique to reduce the inadvertent complications during central venous cannulation. However, USG guided center venous catheterization of internal jugular vein has no difference in comparision to the landmark technique in terms of number of attempts and the time required for successful cannulation.
