PurposeA preliminary observational study was undertaken to evaluate the risk of failure of ultrasound-guided peripheral intravenous catheterization of a deep arm vein for a maximum of 7 days, after peripheral intravenous (PIV) cannulation failure.MethodsThis prospective study included patients referred to the intensive care unit for placement of a central line, a polyurethane cannula commercialized for arterial catheterization was used for peripheral venous cannulation. Catheter length and diameter were chosen based on preliminary ultrasound measurements of vein diameter and skin-vein distance.ResultsCatheterization was successful for all 29 patients. Mean vein diameter was 0.42 ± 0.39 cm; mean vein depth was 0.94 ± 0.52 cm. Mean catheter duration was 6 (median 7) days. Two occluded catheters were removed prematurely. No thrombophlebitis, catheter infection, or extravasation was observed.ConclusionOur results suggest that catheters inserted with the Seldinger method are adapted to prolonged peripheral deep-vein infusion. Ultrasound can play a role in catheter monitoring by identifying early thrombosis formation.
