The complainant reported that the midline catheter was inserted without using a guidewire to stiffen the catheter.The iv rn who placed the catheter had no difficulty and initially had great blood return.Later that day, the floor rn reported difficulty flushing the line and no blood return.The iv rn returned and completed a dressing change and flushed the line, but still had no blood return.The floor rn flushed the line two times by the next morning but still had not blood return.The iv rn retracted the line 2 cm and changed the needleless connector and was able to flush the line and get a good blood return.Upon infusion, the patient reported pain.The line was removed, and the fracture was noticed.The catheter was returned to avi on 29 feb 2024 for investigation.The fracture was observed at the 8cm mark.Partial occlusions were observed distal (downstream) from the fracture.The fracture occurred axially along the catheter tube and had pressure induced stress/fatigue and stretching around the fracture.The cause of this excessive pressure cannot be determined.
