Event Description
|
In the article, "automated red cell exchange in the management of sickle cell disease", the authors describe their experience of automated red cell exchange (a-rce) for management of sickle cell disease since 2011.A transient reduction in the platelet count by 61% was observed after the procedure.This was not associated with any hemorrhagic complications.Despite exposure to large volumes of blood, the alloimmunization rate was only 0.027/100 units of red cells.The absence of any iron loading was confirmed by serial ferriscans, performed over a number of years.Patients with advanced chronic kidney disease showed evidence of iron loading due to reduced innate hemopoiesis and were subsequently switched to simple transfusions.A total of 59% of patients were on regular automated red cell exchange with a history of recurrent painful crises.A total of 77% responded clinically, as evidenced by at least a 25% reduction in their emergency hospital attendance for pain management.The clinical response was gradual and increased the longer patients stayed on the program.The earliest sign of clinical response was a reduction in the length of stay when these patients were hospitalized, indicating that a reduction in the severity of crises precedes the reduction in their frequency.Automated red cell exchange also appeared to be beneficial for patients with recurrent leg ulcers and severe, drug resistant stuttering priapism, while patients with pulmonary hypertension showed a dramatic improvement in their symptoms as well as echocardiographic parameters.Adverse events: ¿ line-related: one episode of sepsis (e.Coli) specific details regarding what, if any, medical intervention was required for the adverse event were not included in the article.The article did not provide specific patient information, therefore this report is being filed as a summary of the event.The disposable sets are not available for return from the customer.

This report is being filed to provide additional information.Investigation: according to the article, "the spectra optia apheresis system (terumo bct) was used by nurses trained and signed as being competent at performing the procedure.Red cell units meeting specifications as per national guidelines for patients with scd [5] were provided by the national blood service.All elective procedures were performed as day cases (ambulatory a-rce) in our day unit with same day discharge for the vast majority of patients.Even though when we first started, intravenous access was via temporary femoral central catheters (vas-cath) for the majority of patients, progressively, an increasing number have the procedure using peripheral access.Currently, 48 of the 68 patients (71%) have the procedure performed through peripheral cannulas, 18 g, 20 g or 22 g according to body habitus, while an additional 15 (22%) through peripheral deep access lines 18 or 20 g, inserted under ultrasound guidance by trained by trained nurses in our day unit.The infusion rate of the citrate anticoagulant is set at 0.6 ml/min when patients first enter the programme and then, if tolerated, increased to 0.8 ml/min." according to therapeutic apheresis: a physician's handbook, adverse events occur during therapeutic procedures with a frequency of 4.8%.Some of the most common reactions include fever, urticaria, hypocalcemic symptoms, pruritus, dyspnea, tachycardia, and mild hypotension.Adverse effects related to vascular access are a frequent concern.Hematoma, venous sclerosis and thrombosis can complicate percutaneous needle puncture.Hemorrhage or pneumothorax or both may complicate cvc insertion, while thrombosis and infection are the most frequently observed complications of prolonged central venous access.During a dressing change, the site should be cleaned and observed for signs of infection such as redness, swelling, drainage, and foul odor.If an infection is suspected, cvc removal should be considered, and the patient should be treated for infection as appropriate.Per internal sterility lab documentation, the devices terumo bct manufactures to collect, separate, and store blood products are terminally sterilized to a sterility assurance level (sal) of =10-6.Additionally, a sterility assurance system has been designed and employed to ensure this sal will be achieved for every lot of product manufactured.The sterility assurance system employed at terumo bct ensures the disposable device is not the source of contamination.Per literature review: escherichia coli is a gram-negative bacterium and is the most numerous aerobic commensal inhabitant of the large intestine.Certain strains cause diarrhea and all can cause infection when they invade sterile sites.Infection of the bloodstream remains a life-threatening occurrence and is most commonly associated with the presence of a central vascular catheter, but may also be associated with a gram-negative infection in other areas of the body, such as the lung, genitourinary tract, or abdomen.Approximately 30% of hospital-acquired bloodstream infections in icus in the united states are due to gram-negative organisms, although this proportion is lower when hospital-wide data are examined.Given an adequate portal of entry, almost any gram-negative organism can cause bloodstream infection; however, the most common organisms include klebsiella species, escherichia coli, enterobacter species, and p.Aeruginosa.[a.Y.Peleg et al.Hospital-acquired infections due to gram-negative bacteria.N engl j med.2010 may 13; 362(19): 1804¿1813 dhr details: since this was a retrospective study including a total of 3107 elective procedures using 25,649 units of red cells performed on spectra optia from june 2011 to october 2020, the lot numbers are unknown; therefore, a dhr search could not be conducted for the reported incident.All lots must meet acceptance criteria for release.Root cause: a specific root cause for the bacterial contamination could not be determined.A possible cause includes but is not limited to: - inadequate maintenance of the central line.
