It was reported that the redo double lumen tpn catheter set leaked at the juncture between the two catheters lumens.During total parenteral nutrition (tpn) via central venous catheter, while flushing both lumens at the same time, it was discovered that the blue hub lumen was occluded.Under the direction of an anesthetist, the staff was instructed to attempt to open the lumen with a 1ml syringe filled with heparin.While actuating the plunger, resistance was lost.It was observed that liquid was emerging from the area of the juncture between the two catheter lumens.The other lumen with a red hub was flushed without complication.The redo double lumen tpn catheter was replaced with a venous port.This was the fifth replacement of this type of central venous catheter in 2018 for this patient.Related mfr.Reports include 1820334-2019-00243, 18203342019-00244, 1820334-2019-00245, 1820334-2019-00246.
