The incidence of artery puncture with central venous cannulation using a modified technique for detection and prevention of arterial cannulation.
Cannulation of the central circulation is essential for management of patients who require major surgery, and for patients who are critically ill. Arterial puncture is the most frequent complication associated with central venous cannulation, and is potentially fatal. Detection of arterial puncture can be problematic, especially in patients with cyanotic congenital heart disease. ⋯ Pressure transduction of the steel needle is a useful technique for detecting arterial puncture and preventing arterial cannulation during attempts to achieve central venous cannulation.

Comparative StudyComparison of the effects of red cell separation and ultrafiltration on heparin concentration during pediatric cardiac surgery.
To determine the effects of red cell separation and ultrafiltration on heparin concentration. ⋯ The plasma concentration of heparin increased after veno-venous modified UF of the patient. Heparin concentration also increased after UF of residual CPB circuit blood. In contrast, circuit blood hemoconcentrated by CS contained minimal heparin, and, when infused, did not increase patient's heparin concentration. ACT and thrombin time did not correlate with heparin concentration.
