Haemovigilance Officer.
Intra-operative Cell salvage: Intra-operative Cell salvage Intra-operative cell salvage is aimed at conserving or avoiding the use of allogenic blood. Blood collected from a surgical field goes through a process of centrifugation where the red blood cells are seperated from other blood components, washed and are ready for re-infusion. (Booke et al. 1997).
Back ground of Cell salvage: Back ground of Cell salvage Technology available since the 1960s / 1970s, limited to simply filtering by gravity.
Advanced from “bowl technology” (discontinuous processing system) to centrifuge system which involves continuous processing.
Benefits of Cell Salvage/CATS: Benefits of Cell Salvage/CATS Avoids exposure to donated products
Eliminates risks of transfusion reactions / errors
Reduces demands on Blood Bank
Cost effective
Objections to Donor Blood / Religious beliefs
Antibodies present
CONTINUOUS AUTOTRANSFUSION SYSTEM (CATS): CONTINUOUS AUTOTRANSFUSION SYSTEM (CATS) Continuous Blood Processing System
Maintains constant high Haematocrit
Complete elimination of fat from bone marrow or subcutaneous fat deposits
Fastest processing time
Single disposable suitable for all applications (paediatric, orthopaedic, cardiac…)
Contra-indications: Contra-indications Sepsis
Malignancy
Contamination
Sickle Cell Anaemia
Blood contaminated with agents e.g. antibiotics etc
Implementation of CATS: Implementation of CATS Multi-disciplinary decision
Patient Safety and Reduction in exposure to allogenic blood
Concerns regarding future emerging pathogens
Rising cost of blood products and increased demands on the blood supply
Aims of Study: Aims of Study Demonstrate the potential and effectiveness of this system
Assess the reduction in allogenic transfusion and thus the reduction in potential transfusion complications
Assess the cost effectiveness of continuous use of this system
Methods Used: Methods Used 143 patients included in study in an emergency / elective surgical setting.
93% were Vascular procedures
71% of patients were male
Mean Age: 69yrs
Range: 22 yrs - 89 yrs
Procedures: Procedures
Procedures: Procedures
Elective Aneurysm Repair: Elective Aneurysm Repair Used a total of 85 times
Total of 50,445 mls re-infused
Range: 85 – 4,200mls
Average: 593mls
Emergency Aneurysm Repair: Emergency Aneurysm Repair Used a total of 35 times
Total of 29,798 mls re-infused
Range: 103 – 2,763mls
Average: 851mls
Other Vascular,Laparoscopies, Laparotomies & Spinal fusion: Other Vascular,Laparoscopies, Laparotomies & Spinal fusion Used a total of 23 times
Total of 15,649 mls re-infused
Range: 73 – 3,600mls
Average: 680mls
Cost Benefits: Cost Benefits Total of 95,892 mls blood re-infused = 331 units of Red Cells (average 290mls per unit)
331 units x € 230 (average price of unit of RCC) = €76,130
Savings on Blood = €76,130
Cost of disposables - €27,955
Total Savings = €48,175
Clinical Benefits: Clinical Benefits 21% (n=30) of patients did not receive any allogenic blood / blood components /products throughout their hospital stay.
A further 10% (n=15) of patients did not receive any blood in the first 24hrs post-operatively, but did require blood prior to discharge.
Benefits to Multi-disciplinary team: Benefits to Multi-disciplinary team Reduced requirement for phlebotomy
Reduced requirement for cross-matching of blood and storage of blood
Time saving for portering staff involved in transport of blood
Time saving for Nursing / Medical staff involved in administration of allogenic blood.

24hr Post-operative Hb: 11.5g/dl, Hct: .335L/L
Discharge Hb: 9.9g/dl, Hct: .290L/L
Post-operative stay: 7 days.
Use of CATS in MPH: Use of CATS in MPH 2001 – 2006
Used a total of 38 times:
THRs (2): 250ml
Revision: THRs: (13) 4,883mls
Spinal Fusions/ Decompressions: (23) 9,453mls
Total 14,586mls
= 50 Units of Red Cells.
Savings on Blood = €11,500
Cost of disposables - €7,428
Total Savings = €4,072
Conclusion: Conclusion CATS has markedly reduced the amount of blood transfused and subsequent complications.
Buffers the demand on the allogenic donor pool.
Cost effective.
Benefits for multi-disciplinary team.
Success of CATS in UCHG: Success of CATS in UCHG A dedicated team was the driving force behind implememting this system and ensuring it would work.
Anaesthetists, Anaesthetic Nurses, Surgeons, Blood Bank & Haemovigilance.
Company support for on-going training.
Written protocols in place re use of machine.
Record of usage maintained
Plans for the future in UCHG: Plans for the future in UCHG Continued use and monitoring of efficacy of CATS
Purchase of two more CATS machines
Proposed Usage for Cardiac Surgery
Use in other areas being explored
National Blood Strategy Group Recommendation 2004: National Blood Strategy Group Recommendation 2004
“All large hospitals set up cell salvage programmes which are well equipped and well staffed. It is in their opinion the best method in avoiding allogenic blood transfusion”.
