A modified technique of percutaneous subclavian venous catheterization in the oedematous burned patient.
Infraclavicular subclavian venepuncture in the oedematous burned patient is often difficult because of increased depth of the vein. In addition, proper patient positioning is not easily achieved because of extensive burns, generalised oedema and bulky dressings. To overcome these difficulties, a modified technique of infraclavicular subclavian venepuncture has been developed. The introducer needle is bent to create a mild curvature. It is inserted at a point 1-2 cm inferior to the palpable lower border of the clavicle along the junction of the middle and medial thirds of the bone, advanced along the deep surface of the clavicle and directed at the superior border of the suprasternal notch. This medial point of insertion shortens the distance of access to the subclavian vein. The curve allows the tip to be kept close to the undersurface of the clavicle as the needle is advanced, thereby reducing the risk of injury to deep structures. The advantages of the modified technique are demonstrated in anatomical dissections. This technique is a viable alternative when conventional techniques fail.
