Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of the supraclavicular approach and the infraclavicular approach for subclavian vein catheterization.
Five hundred emergency department patients requiring subclavian vein catheterization were randomized prospectively into one of two groups, supraclavicular or infraclavicular. If catheterization was unsuccessful in a few attempts using the randomized approach, catheterization with the alternate approach was attempted. Two catheters were available for use, a short, 8-French introducer and a long, 16-gauge catheter. ⋯ Analysis of this series suggests that both the infraclavicular and supraclavicular approaches to subclavian vein catheterization are acceptable alternatives, with little difference in success rate or complications. Using an alternate approach if the initial approach was unsuccessful produced a high overall success rate and a low overall complication rate. A physician who is familiar with both approaches will be more successful at placing central venous catheters safely.
