Obtaining central venous access is important in administering a large volume of fluids, monitoring the fluid balance, and in patients in whom peripheral venous access is difficult to obtain and maintain (as in peripheral edema and pediatric patients). If an ultrasound machine is not immediately available and central venous access via the right jugular vein is required, a simple three-finger technique for insertion of a central venous access line into the vein has proven to be a reliable method for accomplishing this task. This technique works well no matter the patient's body habitus or whether the patient can or cannot rotate their head over to their left side. In essence, the practitioner creates the landmarks required for the successful insertion of a central venous catheter by properly positioning their left three fingers on the patient's neck. The complication rate is no higher than other methods commonly used and might be equal to using ultrasound for placement.
