Pericardial tamponade secondary to perforation by central venous catheters in orthopaedic patients

Pericardial tamponade from an indwelling central venous catheter developed
in four orthopaedic patients. Two of these patients died acutely, and the
other two sustained severe anoxic brain injury. The early signs of
tamponade include tachycardia, hypotension, and increased central venous
pressure. The outcome most often is fatal. When a central venous catheter
has been placed incorrectly or has migrated, it can perforate the heart and
produce pericardial tamponade. To avoid this complication, the tip of the
catheter must be placed within the superior vena cava rather than the right
atrium, and the position of the catheter must be ascertained with a
radiograph of the chest. Prompt recognition and treatment of pericardial
tamponade are imperative if a disastrous outcome is to be prevented.
