title: [Incidents and hazards in the use of blank metal clamps with venous catheters].
abstract: The use of blank metal clamps resulted in severe damaging of infusion systems in two cases. In one case the silicone tube of a Shaldon catheter was damaged by the clamps and thus became detached from the Luer-Lock syringe connecting piece, whereupon the patient bled to death. In another case the too forcible screwing while fastening a Luer-Lock coupling by means of a metal clamp produced a tear in the connecting piece. The female patient, who sat upright, collapsed and died under the clinical suspicion of air embolism, which, however, could not be confirmed at autopsy. Such incidents are avoidable only if doctors and nurses are carefully trained in the handling of vascular catheters and infusion systems and if they are expressly informed not to use blank metal clamps.
