Event Description
|
The customer reported that during a therapeutic plasma exchange (tpe) procedure on a spectra optia device, there were many inlet pressure low alarms and return pressure high alarms and that cells were detected in the plasma line from the centrifuge, possible observed hemolysis.The customer stated that the hemolysis was in the return line and plasma was yellow.The solutions were correctly attached and there were no clots in the channel or channel lines.The customer reported that no medical intervention was given and the patient is in stable condition.The collection set is not available for return because it was discarded by the customer.

Manufacturer Narrative
|
This report is being filed to provide additional information in h.6, h.10 and h.11.Investigation: the customer submitted a photograph to aid the investigation.The first photograph shows a used optia set containing blood throughout loaded on the machine.There is slight color variation in the plasma observed.The second photograph shows blood warmer tubing attached to the device and confirms the presence of hemolysis / plasma discoloration.A third photograph shows the replacement fluid and confirms that the albumin bottle has been vented properly.The last photograph shows the channel connector and it is evident that there is no hemolysis as the plasma is a clear yellow color.A review of the device history record (dhr) for this unit showed no irregularities during manufacturing that were relevant to this issue.A disposable complaint history search was performed for this lot and found one report for similar issues on this lot.See mdr 1722028-2023-00263.Root cause: a root cause assessment was performed for this complaint.Based on the available information a definitive root cause for hemolysis could not be determined but it is likely due to one or a combination of the possible causes listed below: patient's underlying disease state.Patient's medication and/or medical treatment.Hemolysis due to pinched return line resulting in rbc¿s exposed to pressure drop in return line.Hemolysis due to an occlusion in the tubing resulting in rbcs exposed to a pressure drop.
