Problem with pump set for Hospira Pain Management pump

We read with interest Singh’s correspondence regarding the use of ultrasound to investigate the vascular supply to the hand, further illustrating the expanding role of bedside ultrasound in the ICU [1]. A recent long stay patient in our ICU had multiple insertions of intra-arterial cannulae. On day 36 she was noted to have a swelling on the ventral aspect of the left wrist. The vascular supply to the hand was not compromised. Bedside ultrasound with colour flow Doppler (Titan, SonoSite, Biggleswade, UK) clearly demonstrated a false aneurysm of the distal radial artery with flow into the sac across an intimal defect (Fig. 3). Following this prompt diagnosis, ligation of the aneurysm was carried out the same day by the vascular surgeons without complication. Clearly, the role of portable bedside ultrasound examination in the hands of anaesthetists and intensivists goes beyond the mandate provided by NICE guidelines for assisted central venous access [2]. Its expanding role in the ICU has been described [3]. Our case illustrates another situation where this device can facilitate rapid diagnosis and treatment. We have heard our machine described as ‘the intensivists’ stethoscope’; it is certainly becoming an increasingly routine and versatile tool.
