ABSTRACT Purpose: This study aimed to assess the necessity of routine intraoperative cell salvage in liver transplantations. Methods: A total of 327 liver transplants performed between 2014 and 2016 was included in the analysis. Patient data, including pre-transplant examinations, intraoperative red blood cell transfusions, and procedural information, were collected. Results: The median age of the patients was 54 years old, with 67% (219) being male. The most prevalent ABO blood type was O, accounting for 48% (155) of cases. The leading causes of liver disease were hepatitis C (113 cases, 34.6%) and alcohol-related liver disease (97 cases, 29.7%). Out of the 327 liver transplants, allogeneic red blood cell transfusions were administered in 110 cases (34%) with a median of two units of red blood cells per case. Cell salvage was employed in 237 transplants (73%), and successful blood recovery was achieved in 221 cases (93%). Among the group that recovered more than 200 mL of blood, the median volume of recovered blood was 417 mL, with no transfusion of allogeneic blood required. A total of 90 transplants was performed without utilizing cell salvage, and, among these cases, 19 required blood transfusions, with a median of zero units transfused. Conclusions: This study suggests that routine cell salvage is unnecessary for all liver transplantations. The most suitable indication for its use is in patients presenting with portal vein thrombosis and abnormal creatinine levels.

Abstract Objectives To report a case series of Intraoperative Blood Salvage (IOS) in surgeries during the treatment for Slipped Capital Femoral Epiphysis (SCFE) with controlled dislocation of the hip, identifying its efficacy, complications, and the profile of patients with SCFE. Methods Descriptive study reporting a case series, comprising patients seen between January 2016 and March 2018, diagnosed with SCFE, and treated with controlled surgical dislocation of the hip using IOS. Results Sample comprised of 15 patients, with a mean age of 13.1 years. The most affected side was the left with 8 cases. None of the patients required allogeneic blood in the postoperative period. Mean pre- and postoperative hemoglobin were 13.2 and 11.2 g.dL-1, respectively, and mean hemoglobin difference was 1.8 g.dL-1. Mean pre- and postoperative hematocrit were 39.13% and 33.20%, respectively, and mean hematocrit difference was 5.52%. No intraoperative complications were observed. One patient presented vomiting and another one, wound infection in the postoperative period. Conclusion IOS was an alternative blood salvage approach and prevented allogeneic blood transfusion, enabling reduction of potential complications.

RESUMO Objetivo: Avaliar a eficácia da recuperação intraoperatória de sangue (RIOS) na redução da transfusão alogênica em pacientes submetidos à cirurgia para escoliose. Métodos: Estudo retrospectivo de caso-controle, com 69 pacientes submetidos a tratamento cirúrgico corretivo para escoliose, de agosto de 2008 a dezembro de 2014, em hospital-escola. Utilizou-se a RIOS em 43 pacientes e não foi usada em 26. Os grupos foram comparados conforme os prontuários, e os dados foram processados no SPSS 20.0. Nas associações entre a variável RIOS e não-RIOS e as variáveis independentes aplicaram-se os testes do χ2 e de razão de verossimilhança, sendo a força dessas calculada pelo seu IC de 95%. As médias foram comparadas pelos testes t de Student e de Mann-Whitney. O nível de confiança foi 0,05. Resultados: Não houve diferenças significativas entre os grupos com as variáveis idade, sexo, peso pré-operatório, drenagem sanguínea pós-operatória e tempo cirúrgico. Evidenciou-se redução significativa da transfusão alogênica intraoperatória no grupo RIOS submetido à artrodese posterior em comparação com o grupo-controle, sem diferença na transfusão de concentrado de hemácias entre os dois grupos no pós-operatório. Nos 24 pacientes submetidos à artrodese combinada, não houve diferença significativa na transfusão alogênica no intra e no pós-operatório entre os grupos. Conclusão: O sistema revelou-se eficaz em reduzir a transfusão alogênica no intraoperatório de pacientes submetidos à artrodese posterior para escoliose, mas não foi eficaz em reduzir a transfusão alogênica no intra e no pós-operatório daqueles submetidos à artrodese por via combinada.

ABSTRACT Objective: To evaluate the effectiveness of intraoperative blood salvage (IBS) in reducing allogeneic transfusion in patients undergoing surgery for scoliosis. Methods: Retrospective case-control study with 69 patients who underwent surgical treatment for scoliosis correction from August 2008 to December 2014 in a teaching hospital. We used the IBS in 43 patients and it was not used in 26. The groups were compared according to the medical records, and the data were processed on SPSS 20.0. For the associations between the variable IBS and non-IBS and the independent variables we applied the χ 2 and the likelihood ratio tests, and the strength of which was calculated by their 95% CI. The means were compared by Student's t and Mann-Whitney tests. The confidence level was 0.05. Results: There were no significant differences between groups with the variables age, sex, preoperative weight, postoperative blood drainage and surgical time. There was a significant reduction of intraoperative allogeneic transfusion in the IBS group submitted to posterior arthrodesis compared with the control group, with no difference in the transfusion of red blood cells between the two groups postoperatively. In the 24 patients who underwent combined arthrodesis, there was no significant difference in allogeneic transfusion in the intra- and postoperative periods between the groups. Conclusion: The system proved to be effective in reducing allogeneic transfusion during surgery in patients undergoing posterior arthrodesis for scoliosis, but it was not effective in reducing allogeneic transfusion in the intra- and postoperative periods of those undergoing combined arthrodesis.

RESUMEN Objetivo: Evaluar la eficacia de la recuperación de sangre intraoperatoria (RSI) en la reducción de la transfusión alogénica en pacientes sometidos a cirugía para la escoliosis. Métodos: Estudio retrospectivo de casos y controles, con 69 pacientes sometidos a cirugía correctora de la escoliosis, entre agosto de 2008 y diciembre de 2014 en un hospital universitario. Se utilizó la RSI en 43 pacientes y no se utilizó en 26. Los grupos se compararon según los datos de los registros médicos y los datos fueron procesados en el programa SPSS 20.0. En las asociaciones entre la variable RSI y no-RSI y las variables independientes se aplicaron las pruebas de χ2 y la razón de verosimilitud, siendo la fuerza de éstas calculada por su IC de 95%. Los promedios se compararon mediante la pruebas de la t de Student y de Mann-Whitney. El nivel de confianza fue de 0,05. Resultados: No se observaron diferencias significativas entre los grupos en las variables edad, sexo, peso preoperatorio, drenaje de sangre postoperatoria y tiempo quirúrgico. Se mostró una reducción significativa de la transfusión alogénica durante la cirugía en el grupo RSI sometido a la artrodesis posterior en comparación con el grupo de control, sin diferencia en la transfusión de células rojas de la sangre entre los dos grupos después de la operación. En los 24 pacientes que se sometieron a la artrodesis combinada, no hubo diferencia significativa en la transfusión alogénica en el intra y postoperatorio entre los grupos. Conclusión: El sistema ha demostrado su eficacia en la reducción de la transfusión alogénica durante la cirugía en pacientes sometidos a artrodesis posterior para la escoliosis, pero no fue efectivo en la reducción de la transfusión alogénica en el intra y postoperatorio en los que se sometieron a la artrodesis por vía combinada.
