ABSTRACT

OBJECTIVE@#To analyze the conventional application of using comprehensive hemostatic methods during the perioperative period, and the effect of autologous blood transfusion (ABT) device compared with non-negative pressure drainage on preventing blood loss and allogenic blood transfusion after primary total knee arthroplasty (TKA).@*METHODS@#A total of 131 patients (131 knees) with severe knee osteoarthritis who underwent unilateral primary TKA by the same surgeon in Peking University Third Hospital from June 2014 to June 2015 were enrolled in this study. The patients were divided into ABT group (64 patients) and control group (67 patients). ABT devices were used for drainage and blood transfusion in the ABT group while the control group used the non-negative pressure drainage only. The results of the drainage fluid volume, the decrease of hemoglobin, the total blood loss, the hidden blood loss and blood transfusion after TKA were compared between the two groups.@*RESULTS@#The drainage fluid volume in ABT group was significantly higher than that in control group [515 mL (80-1 610 mL) vs. 260 mL (40-670 mL), P<0.001]. The autologous blood transfusion in ABT group was 245 mL (60-1 070 mL). There were no significant differences between the two groups in the value of hemoglobin decrease 1 day after surgery (P=0.340) and 3 days after surgery (P=0.524). There were no significant differences in the total blood loss (P=0.101) and the hidden blood loss (P=0.062) between the two groups either. There were 9 patients in the 131 patients who received allogeneic blood transfusion, of whom 5 in the ABT group (5/64, the blood transfusion rate was 7.8%) and 4 in the control group (4/67, the blood transfusion rate was 6.0%), and no significant differences in the blood transfusion rate between the two groups (P=0.943).@*CONCLUSION@#With the conventional application of using comprehensive hemostatic methods during perioperative period, the ABT device did not show the effective result of controlling postoperative blood loss and failed to reduce the rate of allogeneic blood transfusion in patients with unilateral primary TKA. However, the ABT device could increase the drainage fluid volume and improve the patient's hospitalization expenses. Therefore, there is no need for routine application of ABT device in unilateral primary TKA.

ABSTRACT

INTRODUCTION: Retrograde autologous priming (RAP) is a cardiopulmonary bypass (CPB) method, at low cost. Previous studies have shown that this method reduces hemodilution and blood transfusions needs through increased intra-operative hematocrit. OBJECTIVE: To evaluate RAP method, in relation to standard CPB (crystalloid priming), in adult patients. METHODS: Sixty-two patients were randomly allocated to two groups: 1) Group RAP (n = 27) of patients operated using the RAP and; 2) Control group of patients operated using CPB standard crystalloid method (n = 35). The RAP was performed by draining crystalloid prime from the arterial and venous lines, before CPB, into a collect recycling bag. The main parameters analyzed were: 1) CPB hemodynamic data; 2) Hematocrit and hemoglobin values; 3) The need for blood transfusions. RESULTS: It was observed statistically significant fewer transfusions during surgery and reduced CPB hemodilution using RAP. The CPB hemodynamic values were similar, observing a tendency to use lower CPB flows in the RAP group patients. CONCLUSION: This investigation was designed to be a small-scale pilot study to evaluate the effects of RAP, which were demonstrated concerning the CPB hemodilution and blood transfusions.


INTRODUÇÃO: Perfusato autólogo retrógrado (PAR) é uma técnica de circulação extracorpórea (CEC) com baixos custos. Estudos anteriores demonstraram que esta técnica reduz a hemodiluição e a necessidade de transfusões de sangue por meio do aumento do hematócrito intraoperatório. OBJETIVO: Avaliar técnica de PAR em relação à CEC técnica padrão (perfusato cristaloide) em pacientes adultos. MÉTODOS: Sessenta e dois pacientes foram aleatoriamente alocados em dois grupos: 1) Grupo PAR (n = 27), constituído por pacientes operados utilizando a técnica de PAR e; 2) Grupo Controle, constituído por pacientes operados utilizando técnica padrão de CEC com cristaloides (n = 35). A PAR foi realizada drenando-se o perfusato cristaloide das linhas arterial e venosa, antes da CEC, para uma bolsa coletora de recirculação. Os principais parâmetros analisados foram: 1) parâmetros hemodinâmicos da CEC; 2) valores de hematócrito e hemoglobina; e; 3) necessidade de transfusões de sangue. RESULTADOS: Observaram-se diferenças estatisticamente significativas de transfusão no intraoperatório e diminuição da hemodiluição em CEC utilizando PAR. Os valores hemodinâmicos durante a CEC foram semelhantes, observando-se tendência de utilização de fluxos menores na CEC dos pacientes do grupo PAR. CONCLUSÃO: O presente estudo foi projetado em pequena escala para avaliar os efeitos do PAR, o que foi demonstrado em relação aos já conhecidos efeitos na diminuição da hemodiluição em CEC e transfusão sanguínea, porém não mostrou vantagens hemodinâmicas em relação à técnica padrão com perfusato cristaloide.

ABSTRACT

Los riesgos de la terapia transfusional en general, además del problema del SIDA en particular, constituyen razones de peso en la utilización de técnicas de ahorro de sangre homóloga, en el marco de procedimientos quirúrgicos asociados a pérdidas de sangre considerable. De importancia decisiva resulta el mantenimiento de la normovolemia y de una anemia controlada, a fin de preservar el transporte de oxígeno en niveles adecuados. Todo esto implica una monitorización estrecha y minuciosa del paciente

ABSTRACT

Trabalho de atualizaçäo de conhecimentos relativos à modalidade mais utilizada de autotransfusäo - a reinfusäo. Após revisäo das indicaçöes, métodos e técnicas utilizadas pelo autor (L.B.), desde 1952, foi realizado um cotejo entre a reinfusäo e a transfusäo homóloga comum, em relaçäo às vantagens e riscos de cada um. Comentários finais estimulam o uso do método.

ABSTRACT

Durante el período de julio 1990 a junio de 1991 fueron sometidos a cirugía de revascularización coronaria con circulación extracorpórea tres pacientes Testigos de Jehová, los cuales refirieron profunda convicción religiosa en contra de aceptar sangre homóloga. Se utilizó aparato recuperador de células sanguíneas y no se transfundió sangre. En los tres casos descriptos se observó valores estables de hemoglobina y hematocrito, sin complicaciones

ABSTRACT

La tranfusión de sangre homóloga representa riesgos importantes fundamentalmente ligados a la transmisión de enfermedades virales (Hepatitis, SIDA). Numerosas técnicas de economía de sangre se han desarrollado, para evitar estas complicaciones (Predonación, Hipotensión Controlada, Recuperación intraoperatoria). Sin embargo, la hemorragia quirúrgica no se limita al período intraoperatorio y especialmente en la cirugía traumatológica, las pérdidas postoperatorias son importantes. Se evalúan los efectos de la utilización de un dispositivo (Constavac) diseñado para la recuperación y autotransfusión postoperatoria en pacientes sometidos a cirugía de cadera. Se estudiaron 40 enfermos en los cuales se realizó autotransfusión después de una recolección de 6 h postoperatoria. Se midió Hto, Plaquetas, hemoglobina libre, Tca, Protrombina, fibrinógenos, D-dímeros y Hemocultivos, en distintos períodos del pre y postoperatorio. Los resultados muestran que la técnica produce alteraciones moderadas en los parámetros evaluados y la bacteriología es negativa, se encuentran calofríos en un 7 por ciento de los pacientes autotransfundidos, considerados un efecto menor de la técnica. La recuperación y posterior autotransfusión se sangre en cirugía protésica de cadera es un complemento interesante a considerar entre las técnicas de economía de sangre homóloga
