BACKGROUND: Contrast-induced nephropathy (CIN) is an important cause of iatrogenic morbidity and mortality. The amount of contrast delivered has a major effect on CIN and is operator-dependent. A few studies suggested that the use of automated contrast injection systems is associated with reduced contrast volume. It is unknown whether this is true when smaller amounts of contrast are used and how this is affected by training. METHODS: Volume of contrast media was measured in 1358 consecutive patients undergoing diagnostic catheterization and percutaneous coronary intervention (PCI) from January 31 to May 31, 2011. Patients were allocated to manual stopcock-manifold contrast injection (1052 patients) or automated contrast injection (306 patients). RESULTS: No significant difference in contrast volume use was found between manual and automated contrast injection systems, respectively: diagnostic catheterization, 72 ± 40 mL vs 96 ± 63 mL (P = 0.08); diagnostic catheterization with left ventricular angiography, 98 ± 40 mL vs 95 ± 35 mL (P = 0.51); PCI, 206 ± 82 mL vs 205 ± 90 mL (P = 0.84); diagnostic catheterization and PCI, 264 ± 83 mL vs 253 ± 93 mL (P = 0.51). No significant difference in CIN incidence, according to contrast injection systems, was found among patients receiving PCI (manual 9.8% vs automated 7.4%, P = 0.43). Using smaller sized catheters during diagnostic procedures was associated with injection of smaller amounts of contrast (P < 0.0001). CONCLUSIONS: The use of automated contrast injection for diagnostic catheterization and PCI is not associated with reduced contrast volume as compared with manual injection. The use of smaller calibre catheters might reduce contrast volume.
