Central venous catheterization is a common procedure in the management of critically ill patients, in the context of medical emergencies, and before surgical interventions. Placing a central venous catheter (CVC) in the internal jugular vein (IJV) using anatomical references is associated with a high risk of complications, in particular pneumothorax and arterial puncture. Thus, the placement of CVCs with ultrasound support is recommended by several medical societies and health regulators at the international level. When compared with chest radiography, ultrasound is accessible, safe, cost-effective, and time efficient. This technical report is meant to detail a point-of-care ultrasound protocol designed for the insertion and confirmation of the correct placement of a CVC in the IJV.

Background: Central Venous Catheter (CVC) is an interventional procedure used during anesthesia and critical care for the administration of drugs, fluids and to measure blood pressure as well as other medical uses. There are two methods for the insertion of a Central Venous Catheter, ultrasound imaging, and anatomical landmarks. The CVC is inserted into a central vein such as the internal jugular, Subclavian, and femoral veins in sterile procedures with as few attempts as possible to reduce complications. Objective: The study aimed to review the incidence of complications during the insertion of central venous catheterization guided by ultrasound versus an anatomical landmark. Methodology: The researchers collected papers that met the criteria and were already published in databases, i.e., the Wiley digital library, Scopus, PubMed, Google Scholar, and Cochrane Databases in the period of (2000-2020). The sample consisted of 25 articles. Mesh headings searched included ultrasound, anatomical landmark, central venous cannulation, and complications. Result: Findings of 24 (96%) Randomized Controlled Trials (RCT) in different parts of the world revealed that the ultrasound imaging method has fewer complications than anatomical landmark during central venous cannulation, A p-value<0.05, and only 1(4%) study showed the insignificance with the p-value is >0.05. Conclusion: According to all previous studies, the review concluded that ultrasound imaging is more effective in reducing complications compared to the anatomical landmark technique in patients requiring central venous catheter insertion. And this review is recommending further studies to discover other factors that can reduce the complications.

Background: Catheterization of internal jugular vein can be achieved by either anatomical landmark technique or the ultrasound guided technique. The objective of our study is to find out if ultrasound 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. Methods: Fifty patients scheduled for cardiac surgery requiring central venous cannulation of the right internal jugular vein were divided into two groups: ultrasound guided group 'U' and the landmark group 'L', each consisting of 25 patients with age more than 15 years. The outcomes were compared 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=0.02) in the ultrasound guided and the landmark technique group respectively. Conclusion: Ultrasound guided central venous catheterization of internal jugular vein is comparable to the landmark technique in terms of number of attempts and the time required for successful cannulation. Ultrasound guided technique is much safer than the landmark technique to reduce the overall complications rate during central venous cannulation.

Objective: To determine the advantages of ultrasound guided central venous catheter insertion over anatomical land mark technique regarding ease of insertion and safety. Methodology: Sixty elective patients requiring central venous catheter were selected and randomly divided into two groups, e.g. ultrasound and anatomical landmark groups. Central catheter was inserted under aseptic measures by the same operator. Variables including ease of access, number of attempts, arterial punctures and other complications in both groups were recorded. Results: Ultrasound guidance in central catheter insertion resulted in a statistically significant ease of insertion (P = 0.024). while decreasing number of attempts to gain venous access as compared to the anatomical landmark group (p = 0.0453). Two cases of arterial puncture were recorded in the anatomical landmark group while no arterial puncture occurred in the ultrasound group. P <0.05 was considered significant. Conclusion: Ultrasonographic guidance for central catheter insertion makes it easy and safe as it allows better identification of vascular structures. It also reduces the rate of complications associated with central catheter insertion and improves the success rate thereby justifies its cost. Citation: Rehman A, Zeb H, Niazi AUK.
