InjuryNov 13, 2024Complete Blockage; Complete Blockage
THE DEVICE USER REPORTED THAT THEY HAD A LIVER GOING ON PUMP OVERNIGHT. AT 327 AM EST THE DEVICE USER SENT A MESSAGE STATING "LIVER IS BEING DISCARDED. THERE WAS A DEFECT IN THE RECIRCULATING PUMP LINE THAT PREVENTED THE PUMP FROM REFILLING THE RESERVOIR BAG. THAT COMBINED WITH A HEAVY BLEEDER PREVENTED THE LIVER FROM GETTING PROPER PERFUSION." THE DEVICE USER FURTHER DESCRIBED THAT THE TUBING UNDER THE LIVER BOWL WAS SEALED SHUT AND SINCE IT WAS UNDER THE LIVER BOWL, THEY COULD NOT FIGURE OUT WHY THE RECIRCULATING PUMP WAS SLOW. BY THE TIME THE AREA WAS LOCATED, IT HAD BEEN A LONG TIME WITH AN EMPTY RESERVOIR. IT WAS NOTED THAT THE SEAL TOOK SEVERAL MINUTES TO BREAK AND THE TUBING WAS ALMOST COMPLETELY OCCLUDED AS WELL.

MAUDE report 20679745 ↗InjuryJul 18, 2024Restricted Flow rate; Restricted Flow rate
THE DEVICE USER (DU) REPORTED THAT THERE WAS LITTLE TO NO FLOW NOTED AFTER THE LIVER WAS CONNECTED TO THE DEVICE. DURING TROUBLESHOOTING A DARKENED AREA AT THE TOP OF THE SOFT-SHELL RESERVOIR WAS NOTED AND AIR WAS OBSERVED IN THE TUBING. THE DECISION WAS MADE TO REMOVE THE LIVER AND COLD FLUSH TO AVOID WARM ISCHAEMIA TIME. FOLLOWING ADDITIONAL TROUBLESHOOTING, THE DU DISCOVERED A CLOT IN THE PORTAL CANNULA. THE DEVICE WAS CLEARED OF AIR AND PREPARATION MODE WAS ACHIEVED. IT WAS CONFIRMED THAT THE DU USED THE RECOMMENDED INFUSIONS, BOLUS DRUGS & PRIMING STEPS. ABOUT ONE HOUR LATER THE DU REPORTED THAT THE DEVICE ENTERED LOW RESERVOIR MODE. THIS WAS RESOLVED BY MANIPULATING THE RECIRCULATION PUMP SENSOR RESULTING IN THE VOLUME IN THE BOWL RECIRCULATING INTO THE RESERVOIR. ULTIMATELY, THE DU DECIDED TO DISCARD THE DONOR LIVER DUE TO FAILURE TO CLEAR LACTATE AND FAILURE TO MAINTAIN PH EVEN THOUGH THE FLOWS WERE FINE ONCE THE CLOT WAS REMOVED.

MAUDE report 19320525 ↗InjuryMay 14, 2024Complete Blockage; Complete Blockage
THE DEVICE USER REPORTED THAT MESSAGE CODE 270 (OCCLUDED TUBING) DISPLAYED ON THE DEVICE SCREEN. THE DEVICE USER WAS ABLE TO DETERMINE THAT A SYRINGE INFUSION LINE FOR HEPARIN WAS BEING OCCLUDED BY A PLASTIC FILM IN TWO LOCATIONS. THE FIRST LOCATION WAS WHERE THE TIP OF THE SYRINGE IS SCREWED INTO THE LUER LOCK. THERE WAS PLASTIC FILM THAT WAS OCCLUDING THE SYRINGE LINE FROM BEING PRIMED. THE SECOND LOCATION WAS FURTHER UP THE INFUSION LINE WHERE THE INFUSION TUBING WAS STUCK TOGETHER. IT WAS DECIDED TO DISCARD THE DONOR LIVER DUE TO LACK OF VIABILITY. THE DEVICE USER BELIEVES THAT THE OCCULDED TUBING CONTRIBUTED TO THE LIVER NOT BEING VIABLE FOR TRANSPLANTATION.
