Adición de vancomicina al suero de lavado del recuperador de sangre. Efecto sobre la contaminación bacteriana / Vancomycin added to the wash solution of the cell-saver. Effect on bacterial contamination

Objetivos. Comprobar si la adición de bajas dosis de antibiótico (vancomicina) al suero de lavado del recuperador celular reduce la incidencia de contaminación bacteriana del concentrado de hematíes (CH) autógeno recuperado. Material y método. Estudio experimental, aleatorizado, doble ciego, en forma de grupos paralelos, sobre 20 pacientes consecutivos, programados para cirugía de artrodesis vertebral posterior. La hemorragia intraoperatoria se procesó mediante un recuperador de sangre modelo HaemoLite® 2+, en cuyo proceso los hematíes se lavaron según grupo de aleatorización, con suero fisiológico (grupo control) o con suero fisiológico+10μg/ml−1 de vancomicina (grupo vanco). Se recogieron los datos referentes a edad, peso, volumen procesado y recuperado, hemograma, hemocultivo y concentración de vancomicina del CH obtenido e incidencia de fiebre tras la reinfusión. Resultados. El volumen procesado fue 843±403ml y el volumen recuperado 121±29ml, con hemoglobina 10,4±5,0g/dl−1 y hematocrito 29,1±15,9% (media±DE). El hemocultivo del CH recuperado fue positivo a Staphylococcus coagulasa negativo en 5 casos (50%) en el grupo control mientras que fue estéril en todos los casos en el grupo vanco (p=0,016). La diferencia entre la concentración teórica de vancomicina administrada y la determinada en CH recuperado fue de 1,31μg/ml−1 (IC 95% 1,19-1,43; p=0,074). Conclusiones. La adición de vancomicina a una concentración de 10μg/ml−1 en el suero de lavado del recuperador consigue concentraciones similares en la sangre autógena recuperada y permite la eliminación de las bacterias, obteniéndose hemocultivos negativos en todos los casos (AU)

Objectives. The aim of this study is to test whether the addition of a low-dose of antibiotic (vancomycin) to the wash solution (saline) of the cell-saver reduces the incidence of bacterial contamination of the autologous red blood cell (RBCs) concentrate recovered. Material and method. Experimental, randomized, double-blind, parallel group study performed on 20 consecutive patients scheduled for posterior spinal fusion surgery. Intraoperative bleeding was processed through a cell-saver: HaemoLite® 2+, in which the RBCs were washed according to randomization group, with saline (control group) or saline+10μg/ml−1 vancomycin (vanco group). Data regarding age, weight, processed and recovered volume, blood count, blood culture, and vancomycin concentration in RBCs concentrates obtained and incidence of fever after reinfusion were collected. Results. Processed volume was 843±403ml and recovered volume 121±29ml, with haemoglobin concentration 10.4±5.0g/dl−1 and haematocrit 29.1±15.9% (mean±SD). Recovered RBC concentrate cultures were positive for coagulase-negative Staphylococcus in 5 cases (50%) of the control group while all cultures were negative in the vanco group (P=.016). The difference between the theoretical concentration of vancomycin administered and the concentration determined in the recovered RBC concentrate was 1.31μg/ml−1 (95% CI 1.19 to 1.43; P=.074). Conclusions. The addition of vancomycin at a concentration of 10ug/ml−1 to the wash solution of the cell-saver achieved similar concentrations in the autologous blood concentrate recovered allowing for bacterial removal, with negative blood cultures in all cases (AU)

Ventilación con mascarilla facial en decúbito prono para tratamiento radioterápico en niños / Ventilation with facial mask in the prone position for radiotherapy procedures in children

Objetivos. La ventilación de los pacientes para procedimientos en decúbito prono representa un reto para el anestesiólogo, especialmente cuando se intenta evitar la intubación endotraqueal. Presentamos un estudio concebido para comprobar la efectividad y la seguridad de un prototipo diseñado para ventilación con mascarilla facial en decúbito prono en niños. Material y métodos. Estudio descriptivo prospectivo de 105 sedaciones realizadas en 3 niños programados para tratamiento radioterápico en decúbito prono por meduloblastoma desmoplásico de fosa posterior (2 pacientes de 4 y 6 años de edad) y neuroblastoma en área temporal (un paciente de 4 años). La inducción y el mantenimiento de la sedación se realizaron con sevoflurano en oxígeno, manteniendo ventilación espontánea. Tras la pérdida de consciencia e inmovilidad del paciente se procedía a colocarlo en decúbito prono y a fijar su cabeza con frente y cara apoyadas en un prototipo creado con un molde de poliexpan que contenía la mascarilla facial (conectada a un circuito Mapleson D,) y la parte posterior de la cabeza inmovilizada con una capa de material termoplástico. Se recogieron variables de tiempo y posibles complicaciones. Resultados. Las 105 sedaciones se realizaron según el protocolo previsto. No se produjeron desaturaciones por debajo del 95%, movimientos durante el procedimiento ni otras complicaciones. El tiempo de estancia en el hospital incluyendo procedimiento y recuperación postanestésica fue de 54,4 ± 7,9 min (media ± DE). Conclusiones. El prototipo y técnica de sedación con mascarilla facial en decúbito prono empleados fueron efectivos y seguros permitiendo la realización del tratamiento radioterápico, asegurando la vía aérea de forma mínimamente invasiva, manteniendo la ventilación adecuada, una sedación superficial y posibilitando un alta a domicilio precoz (AU)

Objectives. Ventilation of patients undergoing procedures in the prone position represents a challenge for the anesthesiologist, especially when trying to avoid tracheal intubation. This study aimed to test the effectiveness and safety of a prototype designed for pediatric facial mask ventilation in the prone position. Material and methods. A prospective descriptive study was conducted on 105 sedations performed in 3 children scheduled for radiotherapy treatment of posterior fossa desmoplastic medulloblastoma (6 and 4 y.o. males), and neuroblastoma in temporal area (4 y.o. male). Induction and maintenance of sedation were conducted with sevoflurane in oxygen, maintaining spontaneous ventilation. After achieving loss of consciousness and immobility, the patients were placed in the prone position. Their heads were fixed with the forehead and face supported by a prototype made with a cast of expanded polystyrene (EPS), which held the facial mask (connected to a Mapleson D circuit), and the back of the head immobilized with a layer of thermoplastic material. Time variables and complications were recorded. Results. All sedations were performed according to the planned protocol. All patients maintained oxygen saturation levels above 95%, and no complications were reported. Daily hospital length of stay including the procedure and post anesthetic recovery was 54.4±7.9 min (mean ± SD). Conclusions. The prototype and the sedation technique with face mask in the prone position employed were effective and safe, allowing the completion of the radiotherapy sessions and securing the airway in a minimally invasive way, maintaining adequate ventilation, light sedation and enabling early hospital discharge (AU)

Implementación de un programa de alternativas a la transfusión sanguínea en cirugía de escoliosis en pediatría / Implementation of a patient blood management program in pediatric scoliosis surgery

Objetivos. Determinar si la puesta en marcha de un programa de ahorro de sangre y la adopción y asociación progresiva de diferentes métodos reducen las necesidades transfusionales en pacientes pediátricos intervenidos de escoliosis de múltiples etiologías. Material y método. Estudio cuasiexperimental, no aleatorizado y descriptivo, aprobado por el Comité de Ética para la Investigación de nuestra institución. Se incluyeron 50 pacientes pediátricos (ASA I-III) de edades comprendidas entre los 5 y los 18 años, intervenidos de cirugía de escoliosis de cualquier etiología mediante un único tiempo posterior o doble abordaje, anterior y posterior. Se compararon un grupo histórico (recogida retrospectiva de datos), sin alternativas a la transfusión (Grupo No ahorro = 15 pacientes), y otros 3 grupos prospectivamente: Grupo HNA (hemodilución normovolémica aguda) = 9 pacientes, Grupo HNA + Rec (recuperación intraoperatoria) = 14 pacientes, Grupo EPO (HNA + Rec + eritropoyetina ± donación preoperatoria) = 12 pacientes, conforme se implementaron las diferentes alternativas a la transfusión en nuestra institución. Resultados. La tasa de transfusión en los diferentes grupos (No ahorro, HNA, HNA + Rec, EPO) fue del 100, 66, 57 y 0% de los pacientes, con una media ± DE de 3,40 ± 1,59; 1,33 ± 1,41; 1,43 ± 1,50; 0 ± 0 unidades de CH transfundidas por paciente, respectivamente, con diferencias estadísticamente significativas (p < 0,001) tanto en la tasa de transfusión como en el número de unidades. Conclusiones. La aplicación de un programa multimodal de alternativas a la transfusión sanguínea en cirugía de escoliosis pediátrica, individualizado para cada paciente, puede evitar la transfusión en la práctica totalidad de los casos (AU)

Objectives. To determine whether the implementation of a blood conservation program, and the adoption and progressive association of different methods, reduces transfusion requirements in pediatric patients undergoing scoliosis surgery of different origins. Material and method. Quasi-experimental, nonrandomized, descriptive study, approved by the Ethics Committee for Research of our institution. 50 pediatric patients (ASA I-III) aged 5 to 18 years, undergoing scoliosis surgery of any etiology by a single posterior or double approach (anterior and posterior) were included. A historical group with no alternatives to transfusion: Group No ahorro = 15 patients (retrospective data collection) was compared with another 3 prospective study groups: Group HNA (acute normovolemic hemodilution) = 9 patients; Group HNA + Rec (intraoperative blood salvage) = 14 patients, and Group EPO (HNA + Rec + erythropoietin ± preoperative donation) = 12 patients; according with the implementation schedule of the transfusion alternatives in our institution. Results. The rate of transfusion in different groups (No ahorro, HNA, HNA + Rec, EPO) was 100, 66, 57, and 0% of the patients, respectively, with a mean ± SD of 3.40 ± 1.59; 1.33 ± 1.41; 1.43 ± 1.50; 0 ± 0 RBC units transfused per patient, respectively. Statistically significant differences (P < .001) were found in both the transfusion rate and number of RBC units. Conclusions. The application of a multimodal blood transfusion alternatives program, individualized for each pediatric patient undergoing scoliosis surgery can avoid transfusion in all cases (AU)

Características y calidad de la sangre autóloga recuperada del campo quirúrgico durante cirugía de escoliosis en pediatría / Characteristics and quality of intra-operative cell salvage in paediatric scoliosis surgery

Objetivos. Determinar las características hematológicas y microbiológicas de la sangre recuperada mediante el uso de un recuperador celular con campana centrifugadora pediátrica rígida (100 ml) en cirugía de escoliosis en pediatría y comprobar si se ajusta al estándar esperado en el paciente adulto. Material y método. Estudio de cohorte transversal, descriptivo, sobre 24 unidades consecutivas de sangre recuperada del campo quirúrgico procesadas mediante un recuperador de sangre modelo Haemolite® 2+ (Haemonetics Corp., Braintree, MA, EE. UU.). Se recogieron los datos referentes a edad, peso, abordaje (anterior o posterior) de la cirugía de escoliosis, volumen procesado y volumen de concentrado de hematíes (CH) autógeno recuperado, hemograma y hemocultivo del concentrado obtenido y la incidencia de fiebre tras la reinfusión. Resultados. El volumen procesado fue muy escaso (939 ± 569 ml) con gran variabilidad (coeficiente de variación = 0,6), a diferencia del volumen recuperado 129 ± 50 ml (coeficiente de variación = 0,38). Se estableció correlación estadísticamente significativa entre el volumen procesado y el hematocrito del CH recuperado (Pearson, r = 0,659; p = 0,001) que fue menor del esperado. Los parámetros hematológicos más relevantes de los concentrados recuperados fueron: Hb 11 ± 5,3 g dl−1; HTO: 32,1 ± 15,4%; leucocitos 5,34 ± 4,22 × 103 μl−1; plaquetas 37,88 ± 23,5 × 103 μl−1 (media ± DE). El hemocultivo del CH recuperado fue positivo en 13 casos (54,2%) en los que se aisló Staphylococcus coagulasa (−). Conclusiones. Los recuperadores celulares con campana centrifugadora de volumen fijo (incluso pediátrica) no obtienen la concentración esperada si se procesan bajos volúmenes, por lo que no son la mejor opción en el niño (AU)

Objective. To determine the haematological and microbiological characteristics of blood recovered by using a cell saver with a rigid centrifuge bowl (100 ml) in paediatric scoliosis surgery and to determine whether it conforms to the standard expected in adult patients. Material and methods. A cross-sectional, descriptive cohort study was performed on 24 consecutive red blood cell (RBC) units recovered from the surgical field and processed by a Haemolite® 2+ (Haemonetics Corp., Braintree, MA, EE. UU.) cell saver. Data were collected regarding age, weight, surgical approach (anterior or posterior), processed shed volume and volume of autologous RBC recovered, full blood count, and blood culture obtained from the RBC concentrate, and incidence of fever after reinfusion. Results. The processed shed volume was very low (939 ± 569 ml) with high variability (coefficient of variation = 0.6), unlike the recovered volume 129 ± 50 ml (coefficient of variation = 0.38). A statistically significant correlation between the processed shed volume and recovered RBC concentrate haematocrit was found (Pearson, r=.659, P=.001). Haematological parameters in the recovered concentrate were: Hb 11 ± 5.3 g dl−1; haematocrit: 32.1 ± 15.4% (lower than expected); white cells 5.34 ± 4.22 × 103 ul−1; platelets 37.88 ± 23.5 × 103 ul−1 (mean ± SD). Blood culture was positive in the RBC concentrate recovered in 13 cases (54.2%) in which Staphylococcus coagulase (−) was isolated. Conclusions. Cell salvage machines with rigid centrifuge bowls (including paediatric small volume) do not obtain the expected haematocrit if low volumes are processed, and therefore they are not the best choice in paediatric surgery (AU)

[Anemia in obstetrics and gynecological surgery]. / Anemia en obstetricia y cirugía ginecológica.

Iron deficiency is more common in women due to uterine bleeding, which affects them throughout their fertile life. Additionally, iron needs increase physiologically during pregnancy and breastfeeding. Pregnant women therefore constitute one of the risk groups for iron deficiency. During the postpartum period, iron deficiency is the most common cause of anemia. Longer hospital stays and greater susceptibility to infections are potential consequences of postpartum anemia.

Anemia en obstetricia y cirugía ginecológica / Anemia in obstetrics and gynecological surgery

El déficit de hierro es más frecuente en las mujeres por la hemorragia uterina que les afecta durante toda su vida fértil. Además, durante la gestación y la lactancia, las necesidades de hierro aumentan de forma fisiológica, por lo que la mujer embarazada es uno de los grupos de riesgo predispuesto a presentar déficit de hierro. En el posparto, el déficit de hierro es la causa más frecuente de anemia. El aumento de la estancia hospitalaria o la mayor susceptibilidad para sufrir infecciones son posibles consecuencias de la anemia del posparto (AU)

[Analysis of the training and teaching situation of anaesthesiology and resuscitation tutors in Spain: a proposal for improvement]. / Análisis de la situación formativa y docente de los tutores españoles de Anestesiología y Reanimación. Propuestas de mejora.

OBJECTIVES: To determine the current situation of the tutors in our specialty as regards resident/tutor ratios, times they have available to develop their work, the training that they have received to perform their function, and whether this is recognised by official bodies, other than by their own hospital. Furthermore, to determine the teaching and research work taught to the residents through the sessions, as well as their participation in publications per year. To find out their opinion of the tutors as regards unifying training contents, whether or not they have objective tests on finishing their residency, and their willingness to take part in the project promoted by the Teaching Section of SEDAR to carry out a common minimum theoretical-practical programme throughout the whole of Spain. MATERIAL AND METHODS: A questionnaire with the aforementioned questions was sent to Anaesthesiology Teach Units through the different regional coordinators, during the years 2008-2010. RESULTS: A total of 77/106 (72.6%) Teaching Units responded. The mean ratio of residents per tutor was 5.6±3.3. More than 60% of the tutors had not attended any training course or even how to join one in the two years of the study; 62.3% did not have specific time available to develop their role as tutors, and in 18.2%, their work was only recognised by health institutions. The number of teaching sessions for residents per year was 5.0±4.0 and the number of publications was 1.6±1.4. Almost all of them (98.7%) believe it was necessary to produce a programme that would ensure similar minimum theoretical-practical training plans and that on their own initiative had been carried out in 70% of Teaching Units, but without uniform criteria. Almost three-quarters (74%) had not presented any resident to the European Examination of Anaesthesia in the last few years, and 87% considered the system of evaluating residents as inadequate, with 79% in favour of having a final exam or test. CONCLUSIONS: The tutor/resident ratio should according to that stipulated. Time needs to be set aside for teaching, separate from care work, and our tutors, in general, lack specific training courses, and these are very disparate. There is a general demand to have a training programme of common minimum theoretical-practical skills. It is considered that the current evaluation system is inadequate, but there is no unanimity in whether or not to have an exam at the end of the residency, although the European Examination could be the model to consider in this regard.

Análisis de la situación formativa y docente de los tutores españoles de Anestesiología y Reanimación. Propuestas de mejora / Analysis of the training and teaching situation of anaesthesiology and resuscitation tutors in Spain: a proposal for improvement

Objetivos: Conocer la situación actual de los tutores de nuestra especialidad en cuanto a proporciones residentes/tutor, tiempos de que disponen para desarrollar su labor, la formación que han recibido para realizar su función y si esta es reconocida por los organismos oficiales, más allá de su propio hospital. Asimismo conocer la labor docente e investigadora de los residentes a través de las sesiones que realizaban y las publicaciones anuales en que eran partícipes. Conocer la opinión de los tutores respecto a la unificación de contenidos formativos, que se realicen o no pruebas objetivas al concluir la residencia y su disposición a colaborar en el proyecto, promovido desde la Sección de Docencia de la SEDAR, de colaborar en la aplicación de un programa de mínimos teóricoprácticos común a todo el territorio nacional. Material y métodos: Se envió a los tutores de las unidades docentes de Anestesiología, a través de diferentes coordinadores territoriales, una encuesta con las cuestiones anteriores, durante los años 2008-2010. Resultados: Contestaron 77/106 unidades docentes (72,6%). La razón media de residentes por tutor era 5,6 ± 3,3. Más de un 60% de los tutores no habían recibido ningún curso de formación o a lo sumo uno en 2 años, el 62,3% no disponía de tiempos específicos para desarrollar su función de tutores y su labor sólo era reconocida por las instituciones sanitarias en un 18,2%. El número de sesiones impartidas por los residentes al año era 5,0 ± 4,0 y el número de publicaciones, 1,6 ± 1,4. El 98,7% creía necesaria la elaboración de un programa que garantice unos mismos planes formativos teórico-prácticos mínimos y que, a título individual, habían realizado en un 70% de las unidades docentes, pero sin criterios uniformes. El 74% de los hospitales no habían presentado a ningún residente al Examen Europeo de Anestesia en los últimos 2 años, no se consideraba adecuado el sistema de evaluación de los residentes en un 87%, y un 79% era partidario de realizar un examen o prueba final. Conclusiones: Debe adecuarse la razón residentes/tutor según lo estipulado. Es necesario disponer de un tiempo para la docencia, separado del asistencial y nuestros tutores carecen, en general, de cursos específicos de formación, y estos son muy dispares. Existe una demanda generalizada de realizar un programa formativo común de competencias y mínimos teórico-prácticos. Se considera que el actual sistema de evaluación no es el adecuado, pero no hay unanimidad en si realizar o no un examen al final de la residencia, aunque el modelo del examen europeo podría ser una prueba que considerar a este respecto(AU)

[Continuous spinal anesthesia in obstetrics]. / Anestesia subaracnoidea continua en obstetricia.

Despite the theoretical advantages of continuous anesthesia in obstetric patients (good-quality blockade at low doses, good hemodynamic stability, rapid onset of effect, and no risk of toxicity), little has been published on this technique and its use in pregnancy. Moreover, few descriptive studies or comparative trials have evaluated the efficacy and safety of continuous spinal anesthesia, probably because of concerns about potential adverse effects-principally neurologic complications and postdural puncture headache. We review the literature on the use of continuous spinal anesthesia in obstetric patients, analyzing the advantages and disadvantages, indications, and adverse effects of this technique.

Anestesia subaracnoidea continua en obstetricia / Continuous spinal anesthesia in obstetrics

A pesar de las teóricas ventajas de la anestesia continua en la paciente obstétrica (bloqueo de gran calidad con dosis bajas, gran estabilidad hemodinámica, rapidez de acción y ausencia de riesgo de toxicidad), existe poca bibliografía sobre esta técnica y su uso en la mujer embarazada. Tampoco hallamos muchos estudios que valoren su eficacia y seguridad, bien sean descriptivos o comparando con otras técnicas anestésicas. Esto se debe, probablemente, a la incertidumbre que crea esta técnica sobre la aparición de posibles efectos secundarios, principalmente complicaciones neurológicas y cefalea postpunción dural. El objetivo de este artículo es analizar las ventajas y desventajas, indicaciones, efectos secundarios de la anestesia subaracnoidea continua, así como revisar la bibliografía publicada sobre su utilización en la paciente obstétrica(AU)
