Análisis de la transfusión en la cirugía maxilofacial

espanolObjetivo: Analizar la transfusion en los pacientes de cirugia maxilofacial a partir de los datos de los informes de alta. Material y metodo: Se han estudiado los datos de 569 pacientes intervenidos consecutivamente, codificados segun la Clasificacion Internacional de Enfermedades (CIE-9-MC), evaluando edad, sexo, codigos de diagnosticos, de procedimientos, incluidas las transfusiones, y los codigos de las intervenciones quirurgicas. Resultados: 32 pacientes fueron transfundidos (5,6%). La mayor incidencia ocurrio en los pacientes varones, de edad avanzada, con diagnostico de neoplasias, con la lesion localizada en lengua, resto de la cavidad bucal, mandibula, encias y maxilares, en las cirugias ablativas de tejidos blandos, ortognaticas y reconstructora de huesos y cuando se realiza mas de una tecnica quirurgica durante la intervencion. Sin embargo, mediante analisis de regresion logistica, los unicos factores de riesgo de transfusion fueron el diagnostico y la tecnica quirurgica. Conclusiones: El diagnostico principal y el tipo de cirugia se asocian de modo independiente con el riesgo de transfusion en la cirugia maxilofacial. EnglishPurpose: To analyze the transfusion requirements of patients undergoing maxillofacial surgery. Material and method: Analysis of the codified data in the discharge reports of 569 consecutively operated patients, codified according to the International Disease Classification. Age, sex, diagnosis, procedures, including the transfusions and surgical procedures were studied. Results: 32 patients were transfused (5.6%). The greatest transfusion was detected in males, patients of advanced age, with diagnosis of neoplasia, with the lession in the tongue, mouth, jaw and nasal cavities, in patients undergoing ablative surgery of soft tissues and bone reconstruccion, and among patients in whom more than ane surgical technique was practiced during the intervention. However, controlled the confounding effects by multivariate logistics regression analysis, only diagnosis and surgical procedure were risk factors of blood transfusion. Conclusions: The principal diagnosis and the type of surgery are independently associated with the risk of blood transfusion risk in maxillofacial surgery.
