The passage of central venous catheters either under the technique of anatomical repairs (conventional) or guided by duplex Doppler, is a common practice in the hospital environment. The evidence suggests advantages for the Doppler and access to the subclavian vein or the innominate are the most common. The group is unaware of studies comparing the two approaches. The present analysis evaluates the frequency of early and late complications derived from the catheter passage with the two techniques, by means of a longitudinal descriptive design. Fifty patients were selected, 22 under Doppler guidance and 28 due to anatomical repairs. The total frequency of complications was 20%, and of these 20% early and 80% late. All early complications (pneumothorax and hematoma of the puncture site) and 37% of late complications were used using anatomical repairs, while 63% of the late complications (infection) were found with Doppler. The limitations of the chosen design and the number of patients prevent the generalization of the observations obtained but are useful for future studies. Abbreviations: CVC, central venous catheter; GD, Doppler guide; RA, anatomical repairs.
