Success Rate and Complications of the Supraclavicular Approach for Central Venous Access: A Systematic Review.

Central venous catheterization plays a key role in patients that require immediate resuscitation, long-term fluid management, and invasive monitoring. The supraclavicular (SC) and infraclavicular (IC) approaches are utilized for central venous catheterization and both have their benefits and limitations. In this systematic review, we aim to explore the success rate and various complications of the SC technique. A literature review was conducted on the PubMed, EMBASE, Scopus, CINAHL, and Cochrane databases. All relevant original articles that evaluated success rates and complications of SC access were retrieved and included for qualitative synthesis. After screening 1040 articles, 28 studies were included for further analysis. The overall success rate of SC access ranged between 79% and 100%. The overall complication rate in SC access ranged between 0% and 24.24% (Mean: 4.27%). The most prevalent complication was arterial puncture (1.39%) followed by catheter malposition (0.42%). The SC approach can be used as an alternative to the IC technique because of its low access time and high success rate. The SC approach should be more commonly used in day-to-day central venous cannulation. Further studies on the role of ultrasound guidance are warranted for the SC approach.
