Ultrasound-guided subclavian catheterization in pediatric patients with a linear probe: a case series.

Central venous catheterization (CVC) can be difficult, especially with pediatric patients in critical care. Accessing the subclavian vein (SCV) can cause serious complications, including pneumothorax, arterial puncture, and hemothorax. Recently, the ultrasonographic (USG) technique has gained popularity, but its efficiency is not yet confirmed. Subclavian venous catheterization (SCVC) through the supraclavicular approach (SCA) with USG or accessing the brachiocephalic vein through the infraclavicular approach (ICA) has been reported in the past. A useful technique is reported that involves the use of a 40 mm probe rather than the usual 25 mm probe in order to confirm the location of the needle while successfully performing subclavian venous catheterization in pediatric patients weighing 1.1 kg to 15.0 kg.
