Malposition of percutaneous central venous catheters (PCVCs) in the superior vena cava (SVC) is common. We previously showed that real-time sonography was safer and faster than radiography in identifying PCVC tip location in the inferior vena cava (IVC). However, in preterm infants, determining PCVC tip location in the SVC is complicated by endotracheal or nasogastric tubes in situ and emphysematous lung conditions.
In the study, they concluded that ultrasonography provides an accurate and convenient method by which to assess PCVC tip location in the SVC and to help prevent serious complications that may result from malposition of PCVCs.
