OBJECTIVE: The aim of the study was to evaluate the IVAC P7000 FASTSTART mode with regard to start-up performance in a 50-ml infusion syringe at a flow rate of 1 ml.h-1. METHODS: The time from depression of the start button to first fluid flow (T1) and to establishment of a pre-set flow rate (T2) were gravimetrically recorded with and without FASTSTART and with and without priming of the infusion system with a 1-ml fluid bolus prior to connection of the infusion line to the patient. RESULTS: FASTSTART significantly reduced start-up times in the unprimed syringe pump infusion system from (mean [SD]) 9.4 (6.0) to 2.5 (3.5) min for T1 and from 21.8 (9.8) to 9.4 (6.2) min for T2 (all p < 0.001). The greatest improvement in shortening of T1 and T2 was obtained when the system was primed prior to starting (p < 0.0001). After priming the infusion system, FASTSTART shortened T2 by some 50% from 1.4 (1.4) to 0.7 (0.6) min. CONCLUSION: Our data indicate that the FASTSTART procedure is effective and that substantial improvements can be obtained by priming the system prior to starting.

A central venous port catheter inserted infraclavicularily via the subclavian route may be compressed by the clavicle and the adjacent first rib. It's appearance on chest x-ray has been previously described as the 'pinch-off phenomenon' and requires the removal of the catheter due to a significant risk of fracture. We report the case of a catheter fracture without prior evidence of pinch-off. The free catheter fragment was embolized into the right atrium and caused pericardial effusion. Percutaneous removal of the fragment was attempted but failed and thus open heart surgery with a cardiopulmonary bypass was required. The myocardial lesion caused by the catheter was sutured.
