1.After 2 failed attempts at landmark cannulation. 2.Obese patients 3.IVDU 4.Pediatric patients 5.? Trauma – may take too long. When to use ultrasound

1.Difficult veins remain difficult veins 2.Use little pressure 3.Deeper vein, longer catheter 4.Failure to distinguish artery from vein - compressibility, ?Doppler - Brachial artery, nerve and vein are in close proximity – try to avoid. 5. Failure to identify nerve. Pitfalls of ultrasound guided IV
