The subclavian vein is a commonly used venous access route. Percutaneous cannulation is associated with complications and malpositioning of the catheter. ⋯ Findings show that traditional recommendations for patient positioning with the shoulders retracted and the head turned away can act to distort the subclavian vein anatomy and make successful cannulation more difficult. Positioning the patient flat with the head and shoulders in a neutral position is suggested.
