Correction: the model number should be 1261.20g.The previous initial report listed 1262.20g erroneously.We received a catheter connected to a 3 ml posiflush syringe.The catheter obviously snapped at 4.7 cm.The catheter showed severe occlusion and therefore was not possible to be flushed.A microscopic examination showed a rough, uneven breakage section at the tip of the catheter.Furthermore, there were signs of elongation up to the 7 cm marking of the catheter tube.The involved catheter had been in use for 44 days.When removing the catheter, it should be done by gentle traction close to the insertion site with a slow and steady motion.There is a statement in our product ifu: caution: if difficulty is experienced when removing the catheter, do not apply excessive traction, and stop removal.Use ultrasound along the catheter pathway to analyze the reason for catheter removal blockage.A warm compress above the catheter pathway encourages vasodilation.A gentle vein mobilization at the skin surface may help.Retry removal at a later date if removal is still unsuccessful.Follow your hospital protocol for difficult catheter removal.A review of the batch history records was performed, and no deviations were found.The batch complied to its specification and was released.Each catheter is flow and leak tested during production.The tensile force and dimensions of catheter components are randomly checked.Incoming goods inspections and two 100% visual tests after packaging are carried out with no exceptions found.The mean value of the tensile force of the involved catheter tube was 6 n and therefore within our specification (minimum acceptable value is 3 n).There is one additional complaint for batch 8138570 but this is the first complaint regarding a snapped catheter tube away from the wing on code 4g07126120.This type of defect is included in the risk analysis and its occurrence rate, and the risk evaluation is acceptable.No further corrective action initiated by quality management as there is no hint for a manufacturing fault and the catheter worked well for 44 days.Corrective action: no further corrective action initiated by quality management due to this complaint, as this catheter worked well for 44 days and there are no indications of a manufacturing fault.
