“…se obecně skládají z části drenážní pro odvod krve z rány, makrofiltru (podle systému 120-200 m) (3, 7, 36) pro odstranění detritu tkání a krevních sraženin a vaku či nádoby pro kolekci odvedené tekutiny. Druhá část, sloužící pro návrat krve do oběhu operanta, je vybavena speciálním transfúzním setem s mikrofiltrem (40 m) (8,9,12,24,30,36). Komplety pracují obdobně jako klasická Redonova drenáž, kdy je odsávání zajištěno podtlakem ve sběrné nádobě.…”

PURPOSE OF THE STUDYThe aim of the study was to show advantages of post-operative collection of shed blood and its return to the patient's circulation, using blood-reinfusion sets, in terms of requirements for homologous blood, transmission of infections and posttransfusion reactions in total knee arthroplasty. MATERIALTwo groups of patients were studied. In group 1, comprising 88 patients, shed blood was collected by means of sets for post-operative wound drainage and subsequent autotransfusion. In group 2, with 44 patients, the standard Redon drainage system was used and blood losses were compensated for by homologous blood.Osteoarthrosis of the knee joint was the indication for total knee arthroplasty. Patients with a hemoglobin level lower than 110 g/l, rheumatoid arthropathy, hemophilic arthropathy, coagulopathy, infectious or cancer diseases, or liver or kidney failure were not included, as well as patients who were treated with non-steroid anti-rheumatic drugs, steroids or anticoagulation drugs. METHODSPost-operative blood losses within 6 h of surgery, by 24:00 hours on the day of operation and on the 1st and 2nd postoperative days were recorded. The amount of returned blood and requirements for homologous blood transfusion were also recorded. None of the patients had donated autologous blood. The patients were examined for blood pressure and heart rate; their body temperature was taken, blood samples were collected for blood cell counts and ion (Na + , K + , C1 -) assessment, and urine samples were collected for laboratory tests. All side-effects and complications during hospitalization were recorded as well as all late consequences. The drainage systems used included Redyrob ® CAT, Retrans and Bellovac TM ABT. RESULTSIn group 1, the median value for total post-operative blood loss was 1065 ml, with the median reinfusion value of 500 ml; 31 % of the patients required homologous blood transfusion. In 36 % of the patients, body temperature increased by more than 1 °C, as compared with the value before reinfusion, by 24:00 hours on the operative day, and in 2 % it was higher than 38.5 °C. No infection occurred in the early post-operative period, but late infectious complications resulted in reimplantation in one patient (1 %).In group 2, the median value of post-operative blood loss was 1045 ml and all patients received homologous blood transfusion.Post-operative complications directly related to blood reinfusion, such as febrile reaction, shivering, pruritus, blood pressure or heart rate fluctuation, renal failure or coagulopathy, were not recorded in either group. DISCUSSIONThe use of drainage system allowed us to reduce the need for homologous blood transfusion by 63 %. Blood salvage reported in the relevant literature varies between 8 and 80 %, which reflects differences in views on lost blood compensation. The total blood loss in both our groups was in agreement with the data reported by other authors, and the same held true for the reinfusion volume; most of the authors recommend to use a maximum of 80...
