It was reported that the patient was admitted to sw2 (surgical unit) on (b)(6) 2017 for cellulitis to the right hand and removal of cannula that was retained in her arm 7 years ago.The suspect device was placed by an anesthetist to the patient's left ankle (at a point of flexion) midday on the day of admission.The insertion was noted to be successful upon first attempt, reporting the catheter/stylet was not withdrawn at any time during the procedure.On (b)(6) 2017, the patient rang her bell and requested to have her infusion reconnected to her iv.The nurse flushed the suspect device with normal saline 5ml and the patient complained of pain.The flush was stopped and the site was checked by removing the bandage.Leakage was noted and when the nurse removed the tegaderm dressing to remove the device, the tip of the cannula was missing.At 0740, after patient handover was finished, the nurse who initially discovered the missing cannula called an additional nurse to assess the iv site.This nurse noted the tegaderm had been pulled halfway from the site and noted the "front part of the loop missing and not visible, only the end part and the claves (sp)" could been seen.The site was palpated, which proved very painful and minimal swelling was noted to the ankle area.The nurse did not feel anything under the skin upon palpation and no bleeding was noted.The doctor was notified and x-rays were ordered.Results of a left limb ultrasound showed hyperechoic cannulated structure to the medial ankle in the subcutaneous soft tissue.The patient reported severe pain over the next 12 hours and was given dicloflame, tramacet, and tramal for the pain.Surgery was performed to remove the broken catheter.
