Subclavian vein catheterization.

Massive fluid replacement is occasionally useful for resuscitation of severely injured patients. The use of MAST garment and the inability to obtain peripheral intravenous access may necessitate the use of infraclavicular subclavian cannulation. Two modifications of the standard subclavian technique have been described which enable quick access for infusion of large fluid volume and autotransfusion. The first involves the placement of multiple catheters in the same vein. The second method utilizes a modified Seldinger technique to place an 8 F. Swan-Ganz introducer into the subclavian vein. Complications are similar to those encountered when the standard subclavian technique is utilized.
