Point-of-care ultrasound for central venous catheter confirmation and complications in the emergency department: A systematic review and meta-analysis

= 0.86), although power was limited.ConclusionsIn emergency department settings, point-of-care ultrasound provides highly specific and rapid confirmation for detecting central venous catheter malposition, supporting prompt rule-in decisions and potential workflow acceleration. Given heterogeneous sensitivity and limitations of reference standards, negative results should be interpreted cautiously, with confirmatory imaging reserved for equivocal examinations or high-risk scenarios.
