It was reported that the bd arterial cannula experienced the catheter separating from the hub.The product defect resulted in medical intervention, with an ultrasound scan being administered where it was confirmed that the separated cannula remained embedded within the patient's left wrist.After consultation with their vascular team, it was determined that it was safe to leave the cannula for the time being, with follow-up planned for the following week.There has been no additional information provided regarding the final outcome of the incident.The following information was provided by the initial reporter: patient was recovering following an emergency laparotomy.I noticed that the arterial trace was giving obscure readings and the anaesthetist advised me to use non-invasive blood pressure (nibp) readings.He asked me to remove the arterial cannula prior to the patient going back to alex ward.As i began to withdraw the art cannula, i noticed a small blood clot sitting on the base of the cannula hub.As i withdrew the cannula further i saw that the cannula catheter was not attached to the hub.I asked 2 x colleagues for help, and pressure was applied to the wound site (left wrist).The emergency anaesthetist was then called for, and he asked for a sonosite scan so that he could confirm that the cannula catheter had been left in the patient's artery.The sonosite proved this was true.He then rang uhcw vascular team to ask for advice.He was advised via the vascular sho that as long as the patient had a palpable pulse in her left wrist, the hand was pink and warm, there was no discoloration, the patient felt no pain, or pins and needles and that due to the patient just having had emergency surgery, it would be safe to leave the broken cannula in site and that the vascular team would follow up during the next week.The patient was aware that there had been issue, but no official duty of candour was carried at this time, due to the effects of the anaesthetic.
