ObjectivesThe purpose of this study is to describe a novel method to visualize the position of central venous catheters, which is safe, expeditious, and less expensive than the routine postprocedural chest radiograph.DesignRetrospective comparative study.SettingDialysis Center of the Department of Nephrology, Klinikum rechts der Isar, Technische Universität München, Munich, Germany.PatientsTwo hundred and two adult patients undergoing central venous catheter placement for dialysis, plasmapheresis, or administration of medication and solutions.InterventionsNone.Measurements And Main ResultsData of 202 adult patients with 219 central venous catheterizations were retrospectively analyzed. Each catheter insertion was followed by an agitated saline bubble-enhanced transthoracic echocardiography, which was used to localize the tip of the catheter. The position of catheter was then controlled by chest radiograph in all cases. During the 13-month study period, two catheter malpositions occurred. Both were identified by agitated saline bubble-enhanced transthoracic echocardiography and confirmed by chest radiograph. The mean time between catheter insertion and chest radiograph control (28.3 min) was clearly longer than agitated saline bubble-enhanced transthoracic echocardiography (3.2 min) (p < 0.001). The total costs of the procedure were reduced by 86.7-95.0%. Specific complications related to the procedure were not observed.ConclusionsThe results revealed that the accuracy of agitated saline bubble-enhanced transthoracic echocardiography is equivalent to the chest radiograph. It offers a safe, cost-effective, expeditious alternative to routine chest radiograph for position controls of central venous catheters.
