Four incidents of catheter separation in three patients during left heart catheterization and coronary angiography are presented. In two cases the catheters had been used before. After the second incident, we decided to use angiography catheters once only. All catheter fragments were removed under local anesthesia, and no further complications arose. In all incidents the point of catheter fracture was near the bond between the body of the catheter and its tip. We believe that catheter separation is related to polymer aging. The catheters in the third and fourth incidents were unused, but there was no expiration date on their packages. We recommend that (1) expiration dates be clearly stated on every catheter package, (2) catheter manufacturers issue warnings not to use catheters after expiration date, and (3) unused angiography catheters with no expiration date not be used. We also suggest that consideration be given to using catheters once only.

    Background A variety of suction catheters (type, size and design) are recommended for oropharyngeal suctioning of meconium during newborn resuscitation, but it is not known which performs best. In this study we compared different sizes of soft catheters, the Yankauer (YK) and the portable bulb...

    Introduction: Functionally univentricular hearts palliated with superior or total cavopulmonary connection result in circulations in series. The absence of a pre-pulmonary pump means that cardiac output is more difficult to adjust and control. Continuous monitoring of cardiac output is crucial...
