ABSTRACT
OBJECTIVE: To assess the safety and efficacy of using the Anesthetic Conserving Device (AnaConDa) when maintaining sedation after cardiac surgery. MATERIAL AND METHODS: Descriptive study of 46 consecutive patients in the postoperative recovery unit after cardiac surgery between January and April 2009. The patients were under sevoflurane sedation administered with the AnaConDa placed in the inhalation tube. No exclusion criteria were established before enrollment. The sevoflurane dose was set using the manufacturer's normogram and was later adjusted to give an end-tidal concentration of sevoflurane between 0.5% and 0.7% on the basis of data from a gas analyzer. Remifentanil was administered to all patients; a fast-track extubation protocol was used. The only criterion for excluding a patient's data from analysis was prolonged sedation (> 5 hours). RESULTS: The mean (SD) time patients were under sedation with the AnaConDa in place was 2588 (12.32) minutes. The end-tidal concentration of sevoflurane never exceeded 1%. Scores on the Richmond agitation-sedation scale were -5 at 60 minutes in all cases; there was some score variability at 120 minutes. Deeper sedation was desired for the first 60 minutes to avoid awakening related to rewarming. The mean time until awakening was 6.17 minutes (range, 1-30 minutes). The mean time until extubation was 43 (6.69) minutes. The most common adverse effect was arterial hypotension (12 cases). Hypotension was related to bleeding in 3 patients and to low cardiac output in 4 patients. CONCLUSION: Administering sevoflurane through the AnaConDa can be a safe, valid, and reliable method for sedating patients after cardiac surgery. With this device, it is possible to monitor the concentration administered.

Objetivos: Día a día se pone de relevancia la importancia que representa el tratamiento correcto del dolor agudo postoperatorio en el devenir del paciente durante su estancia hospitalaria. Aprovechando una variación de infraestructura en nuestro complejo, y percatándonos del regular control analgésico que se producía en determinados pacientes, en este trabajo pretendemos destacar la importancia que tiene que este manejo lo dirijan los servicios de Anestesiología. Material y métodos: El estudio, llevado a cabo en la Unidad de Cirugía Ortopédica del Complejo Hospitalario Universitario de Badajoz y cuya duración fue de 2 meses, se distribuyó en 2 grupos de trabajo. El grupo A (artroplastia) contaba con 33 pacientes y el grupo B (artroscopia), con 15 pacientes. Recogimos los datos pertinentes para el análisis posterior (estudio observacional descriptivo), así como una encuesta realizada a los facultativos del Servicio de Traumatología y personal de enfermería que recogen una serie de ítems para establecer un criterio sobre los conceptos a estudiar. Resultados: Se encontraron 2 déficits fundamentales: en primer lugar, los valores de dolor percibidos por los pacientes fueron mayores de los deseables y, en segundo lugar, las técnicas analgésicas que se ponían en práctica no eran las más adecuadas ni eran multimodales. Conclusiones: A partir de los resultados, estimamos fundamental el concurso de los servicios de Anestesiología en el manejo del dolor postoperatorio, ya que la satisfacción final del paciente se vería mejorada de gran manera. Aunque no sean objetivos del estudio, los días de ingreso hospitalario y la aparición de morbilidad asociada a la cirugía a buen seguro se verían reducidos fundamentándonos en la bibliografía existente. Además, las encuestas realizadas nos muestran el déficit de protocolos, actitudes clínicas y formación que reclaman médicos y personal de enfermería (AU)
Objectives: The correct management of acute postoperative pain is becoming increasingly important for the progression of the patient during their hospital stay. Taking advantage of a change in the infrastructure of our complex, and being aware of the regular analgesic control required by certain patients, in this study we attempt to highlight the importance of this analgesic management being directed by the Anaesthetic Department. Material and methods: This study was performed in the Orthopaedic Surgical Unit of the Badajoz (Spain) University Hospital Complex, lasted 2 months, and included two working groups consisting of Group A (arthroplasty) with 33 patients and Group B (arthroscopy) with 15 patients. We collected the relevant data for subsequent analysis (descriptive observational study), as well a survey carried out on the physicians of the Traumatology Unit and nursing staff, which collected a series of items to establish an opinion on the concepts to study. Results: Two fundamental deficiencies were found. Firstly, the levels of pain perceived by the patients were higher than those desired, and secondly, the analgesic techniques that were being practiced were not the most adequate and were not multimodal. Conclusions: According to the results we consider the support of the Anaesthetic Department as fundamental in the management of postoperative pain, since the final satisfaction of the patient would improve greatly. Although they were not objectives of the study, the days in hospital and the appearance of morbidity associated with the surgery would surely be reduced based on the existing literature. Furthermore, the surveys carried out showed a lack of protocols, clinical attitudes and training that the physicians and nurses demand (AU)
