Background: Beta blockers are recommended by the American College of Cardiology/American Heart Association Guidelines for high and intermediate-risk cardiac patients undergoing non-cardiac surgery. Beta blockers are a class of drugs that moderate the effects of increased catecholamine levels on the heart by selectively blocking beta receptors in the heart and blood vessels, resulting in a lower heart rate and blood pressure. Beta blocker use perioperatively has been shown to reduce the risk of ischemia and infarction. Purpose: The purpose of this project is to address beta blocker use in a group of anesthesia providers who routinely attend to high-risk and intermediate-risk cardiac patients undergoing non-cardiac surgery in a medium-sized private hospital in suburban South Florida. There are barriers to the implementation of the published guidelines for beta blocker administration, including lack of awareness of the best current practice and a lack of a formal beta blocker protocol at the institutional level. Methods: A simple and inexpensive beta blocker protocol was implemented and evaluated by various means. Beta blocker administration practices were examined and documented prior to and after protocol implementation. Beta blocker usage was examined prior to and after protocol implementation Findings/Implications: It was hypothesized that increased anesthesia provider awareness would lead to increased administration of perioperative beta blockers to high-risk and intermediate-risk cardiac patients undergoing non-cardiac procedures. Although there was a knowledge increase related to the new beta blocker protocol, no change in practice was observed.

Background Oxygen is one of the most commonly used drugs by anesthesiologists. The World Health Organization (WHO) gave recommendations regarding perioperative oxygen administration, but the practice of oxygen use in anesthesia, critical emergency, and intensive care medicine remains unclear. Methods We conducted an online survey among members of the European Society of Anaesthesiology and Intensive Care (ESAIC). The questionnaire consisted of 46 queries appraising the perioperative period, emergency medicine and in the intensive care, knowledge about current recommendations by the WHO, oxygen toxicity, and devices for supplemental oxygen therapy. Results Seven hundred ninety-eight ESAIC members (2.1% of all ESAIC members) completed the survey. Most respondents were board-certified and worked in hospitals with > 500 beds. The majority affirmed that they do not use specific protocols for oxygen administration. WHO recommendations are unknown to 42% of respondents, known but not followed by 14%, and known and followed by 24% of them. Respondents prefer inspiratory oxygen fraction (FiO2) ≥80% during induction and emergence from anesthesia, but intraoperatively < 60% for maintenance, and higher FiO2 in patients with diseased than non-diseased lungs. Postoperative oxygen therapy is prescribed more commonly according to peripheral oxygen saturation (SpO2), but shortage of devices still limits monitoring. When monitoring is used, SpO2 ≤ 95% is often targeted. In critical emergency medicine, oxygen is used frequently in patients aged ≥80 years, or presenting with respiratory distress, chronic obstructive pulmonary disease, myocardial infarction, and stroke. In the intensive care unit, oxygen is mostly targeted at 96%, especially in patients with pulmonary diseases. Conclusions The current practice of perioperative oxygen therapy among respondents does not follow WHO recommendations or current evidence, and access to postoperative monitoring devices impairs the individualization of oxygen therapy. Further research and additional teaching about use of oxygen are necessary.

Survey on maternal satisfaction in receiving spinal anesthesia for Cesarean section / A quantitative descriptive and cross-sectional study was conducted. The purpose of the study was to evaluate the maternal satisfaction after the experience of spinal anaesthesia for Caesarean section in one public hospital of Gauteng Province in South Africa. Data were collected by administering a questionnaire which included the demographic profile and satisfaction score in terms of perioperative elements to 82 women in their postoperative period. Analysis of data was performed by The Statistical Package for the Social Sciences (SPSS) version 13 and Excel 2010 was used for tabular and graphical illustrations. The findings revealed that the majority of women studied were black (95,1%), not married (73,2%) and unemployed (64,6%). The levels of maternal satisfaction in terms of intraoperative, postoperative and other perioperative elements were high, at 94,4%, 90,3% and 85,4% respectively. The lowest percentage (76,8%) was found for the maternal satisfaction about the preoperative explanation. The overall level of maternal satisfaction in this study was 86,7%. The majority of women (82,9%) would opt for spinal anaesthesia in future, while 6,1% would not accept it and 11,0% were not sure if they would opt for it or not. / Health Studies / M.A. (Public Health)

Introdução: A atelectasia intraoperatória ocorre imediatamente após a indução anestésica e pode ser detectada por ultrassom pulmonar (LUS). No entanto, até o momento o LUS não é utilizado para avaliar a hiperdistensão pulmonar. Neste estudo, descreveu-se um método para detectar hiperdistensão pulmonar usando LUS. A tomografia de impedância elétrica (TIE) foi a referência para comparação dos métodos. Métodos: Dezoito (18) pacientes, com 63 ± 6 anos de idade, com pulmões normais, submetidos à cirurgia abdominal inferior. O TIE foi calibrado, realizada a indução anestésica, intubação e ventilação mecânica. Para reverter a atelectasia posterior, realizou-se uma manobra de recrutamento alveolar com o uso de pressão expiratória final positiva (PEEP) 20 cmH20 e pressão aérea do platô 40 cmH2O durante 120 segundos. A titulação PEEP foi então obtida com valores descendentes: 20, 18, 16, 14,12,10, 8, 6 e 4 cmH2O. Os dados de ultrassom e TIE foram coletados em cada nível PEEP e interpretados por dois observadores independentes. O número de linhas H foi contado usando um filtro especial. O teste de correlação de Spearman e a curva ROC foram utilizados para comparar os dados do LUS e TIE. Resultados: O número de linhas H aumentou linearmente com PEEP: de 3 em PEEP 4 cmH2O a 10 em PEEP 20 cmH2O. Cinco linhas H foram o limiar para a detecção de hiperdistensão pulmonar, definida como hiperdistensão na TIE >= 24,5%. A área sob a curva ROC foi 0,947 (IC 95% 0.901-0.976). Conclusão: O LUS intraoperatório detectou hiperdistensão pulmonar em valores descendentes de PEEP. A presença de cinco ou mais linhas H podem ser consideradas como indicando hiperdistensão pulmonar / Purpose: Intraoperative atelectasis occurs immediately after anaesthetic induction and can be detected by lung ultrasound (LUS). However, LUS is considered as unable to assess pulmonary hyperinflation. In this study, we propose a method to detect pulmonary hyperinflation using LUS. Electrical impedance tomography (EIT) was the reference method. Methods: We included 18 patients, 63 ± 6-year old, with normal lungs, undergoing lower abdominal surgery. The following protocol was used: EIT was calibrated, followed by anaesthetic induction, intubation and mechanical ventilation. To reverse posterior atelectasis, a recruitment maneuver - positive end-expiratory pressure (PEEP) 20 cmH20 and plateau airway pressure 40 cmH2O during 120 sec was performed. PEEP titration was then obtained during a descending trial: 20, 18, 16, 14,12,10, 8, 6 and 4 cmH2O. Ultrasound and EIT data were collected at each PEEP level and analyzed by two independent observers. The number of H lines was counted using a special filter. Spearman correlation test and ROC curve were used to compare LUS and EIT data. Results: The number of H lines increased linearly with PEEP: from 3 at PEEP 4 cmH2O to 10 at PEEP 20 cmH2O. Five H lines was the threshold for detecting pulmonary hyperinflation, defined as a mean decrease in maximum EIT compliance >= 24,5 %. The area under the ROC curve was 0.947 (CI 95% 0.901-0.976). Conclusion: Intraoperative transthoracic LUS can detect pulmonary hyperinflation during a PEEP descending trial. Five or more H lines can be considered as indicating pulmonary hyperinflation in normally aerated lung regions

Introdução: as tecnologias educativas podem ser aplicadas por meio de materiais educativos, folhetos, vídeos, jogos ou qualquer outra estratégia que tenha por objetivo auxiliar a compreensão e aumentar o conhecimento de pacientes sobre sua saúde ou tratamento. Objetivo: avaliar a eficácia de uma tecnologia educativa impressa na redução de sinais e sintomas perioperatórios em pacientes submetidos à cirurgia ortognática. Método: trata-se de um ensaio clínico randomizado controlado desenvolvido no período de janeiro de 2013 a agosto de 2015, dividido em duas fases: um estudo piloto sem randomização para teste da intervenção e instrumentos, com oito pacientes; e, em segundo momento, o estudo clínico com as alterações decorrentes do estudo piloto. A amostra randomizada por blocos foi constituída de quarenta pacientes (vinte experimental e vinte controle), com seguimento de 45 dias. No grupo experimental, foi realizada a orientação pré-operatória pela enfermeira com auxílio da tecnologia educativa construída previamente para esse perfil de paciente e com orientação sobre os cuidados pós-operatórios (higiene oral, dieta, exercícios faciais, hidratação labial, exposição ao sol, abertura limitada da cavidade oral, controle da dor, repouso, banho e curativos), além da orientação habitual do cirurgião. O grupo controle recebeu somente as orientações rotineiras do cirurgião. Para a análise da intervenção, foram aplicados instrumentos para avaliar o conhecimento sobre os cuidados pós-operatórios, ansiedade pré e pós-procedimento pelo inventário de ansiedade IDATE traço e estado, sinais e sintomas do pós-operatório por instrumento de avaliação clínica. Na análise estatística, foi aplicado teste modelo de efeitos mistos para investigação dos dados do inventário de ansiedade traço-estado, teste de conhecimento e avaliação clínica, com exceção das medidas de peso corporal e dor para os quais foram utilizados GEE (=5%). Resultados: em relação ao teste de conhecimento observou-se melhora significativa do conhecimento no grupo experimental (p=0,000), o Inventário de ansiedade IDATE estado não apresentou diferença estatística entre a evolução nos dois grupos (p=0,818), e também no IDATE traço (p=0,906). Na avaliação dos sinais e sintomas por meio da análise clínica, não se observou diferença significativa entre a evolução dos grupos em todos os itens avaliados, mas notou-se no grupo experimental reduções mais expressivas entre o primeiro e segundo retorno em alguns sinais e sintomas do que no grupo controle. Esses pacientes também apresentaram menor dificuldade em realizar as refeições, iniciaram os exercícios faciais precocemente e utilizaram métodos de conforto para dormir e respirar melhor, itens correspondentes na orientação e na tecnologia educativa impressa aplicada. Conclusão: a estratégia de orientação e aplicação da tecnologia educativa para pacientes submetidos a cirurgia ortognática foi efetiva para o conhecimento dos pacientes sobre a cirurgia e o autocuidado. Observou-se melhora dos desfechos avaliados e sua implantação merece ser considerada para auxiliar o pós-operatório desses pacientes.

Objective: To evaluate the efficacy of a printed educational technology in reducing signs and symptoms in perioperative patients undergoing orthognathic surgery. Method: this is a randomized controlled clinical trial carried out from January 2013 to August 2015, divided into two phases: A pilot study without randomization to test the intervention and instruments with eight patients, and the second time, the study clinical with the changes arising from the pilot study. A random sample of blocks consisted of 40 patients (20: experimental and 20: control), with follow-up of 45 days. In the experimental group the preoperative orientation was conducted by nurse with the help of educational technology previously built for this patient profile and guidance on post-operative care (oral hygiene, diet, facial exercises, lip hydration, sun exposure, aperture limited the oral cavity, pain control, rest, bathing and dressing), besides the usual surgeon orientation. The control group only received routine guidance of the surgeon. To evaluate the intervention were implemented instruments to assess knowledge about post-operative care, pre and the post-procedure Anxiety Inventory STAI trait and state anxiety, signs and symptoms postoperatively by clinical assessment tool. Statistical analysis: applied testing mixed-effects model for data analysis inventory of State-trait anxiety, knowledge test and clinical evaluation, with the exception of body weight measurements and pain that were used GHG (=5%). Results: in relation to knowledge we observed significant improvement of test knowledge in the experimental group (p=0.000), the state STAI Anxiety Inventory showed no statistical difference between the evolution in both groups (p=0.818), and also in trace IDATE (p=0.906). In the evaluation of the signs and symptoms through clinical evaluation there was no significant difference between the evolution of groups in all items, but was noted in the experimental group more decreases between the first and second return in signs and symptoms than in group control. These patients also had less difficulty in performing meals, facial exercises began early and comfort of methods used to sleep and breathe better by matching items in orientation and printed educational technology applied. Conclusion: the orientation of strategy proposed and application of educational technology for patients undergoing orthognathic surgery was effective in patients\' knowledge about surgery and self-care. There was a significant improvement in outcomes, although without statistical significance and the use of educational technologies deserve to be considered to assist the postoperative these patients.

These statistics are further evidence that of the 234 million patients undergoing surgeries, seven million suffer postoperative complications, increasing mortality rates by around 0.4 to 10%. A surgical site infection is considered the second highest incidence of major impact to the morbidity and mortality of patients, and may cause irreparable physical and emotional harm, as well as increase the cost of therapy for institutions. This reality drove the Safe Surgery Saves Lives program, which is the second Global Challenge for the World Alliance for Patient Safety program, launched by the World Health Organization in 2004. Studies organized by the National Health Surveillance Agency of Brazil, derived from these campaigns, cataloged nine process indicators to prevent these infections, which were the subject of this investigation. OBJECTIVE: To examine the process indicators for the prevention of surgical site infection in the perioperative period in patients undergoing clean surgery in a teaching hospital in central-western Brazil. METHODS: Retrospective analytical cohort study, conducted in 700 records of patients aged 18 years or older undergoing clean surgical procedures from January 2008 to December 2010. We used a structured form, previously evaluated according to national guidelines. Data were entered into SPSS version 15 for Windows. The analysis was descriptive and multivariate, and used chi-square tests, Fisher, and odds ratio (OR) as measures of association for variables with p <0.10. Statistically significant associations with p <0.05 were considered. RESULTS: Regarding the socio-demographic profile of the patients, 57.1% were female, aged between 18 and 101 years, 39.3% had comorbidities, 74.5% with ASA ≤ II. Regarding surgical specialty, 29.9% were orthopedic and 19.9% were vascular. Nonconforming indicators were found in 64.6%. Aspects such as the time of preoperative hospitalization, the method used for hair removal, the duration of antimicrobial prophylaxis, glycemic control in diabetics, as well as the thermal controls and inspection records of the surgical cases were not considered appropriate. The predictors for surgical site infection in the univariate analysis were male gender, carriers of chronic disease, alcoholism and smoking, infections already present on admission, a length of preoperative hospital stay of greater than 5 days, ASA ≥ III, shaving and antimicrobial prophylaxis; the independent factors were: being a carrier of a chronic disease, infections already present on admission and shaving with a razor blade. The estimated rate of infection was 10%. The surgical specialty with the highest rate of infection was vascular, with 25.9%. The methicillin-resistant Staphylococcus aureus was the most evident causative agent. CONCLUSION: We conclude that the service partially meets the process indicators for the prevention of surgical site infection in the perioperative period of clean surgeries, incongruent with the principles of the Safe Surgery Saves Lives program. / INTRODUÇÃO: Evidências apontam que, de cada dez pessoas no mundo, uma tem sido vítima de erros ou eventos adversos evitáveis. As estatísticas reforçam que, dos 234 milhões de pacientes submetidos a procedimentos cirúrgicos, sete milhões sofrem complicações pós-operatórias, elevando as taxas de mortalidade em torno de 0,4 a 10%. A infecção do sítio cirúrgico é considerada como o segundo incidente de maior impacto para a morbimortalidade dos pacientes, podendo gerar prejuízos físicos e emocionais irreparáveis, além de onerar os custos com a terapêutica para as instituições. Essa realidade impulsionou o programa Cirurgias Seguras Salvam Vidas, o qual representa o segundo Desafio Global da Aliança Mundial para a Segurança do Paciente, lançado pela Organização Mundial da Saúde, em 2004. Estudo organizado pela Agência Nacional de Vigilância Sanitária do Brasil, proveniente dessa campanha, catalogou nove indicadores de processo para prevenção dessas infecções, os quais foram objeto dessa investigação. OBJETIVO: analisar os indicadores de processo para a prevenção da infecção do sítio cirúrgico no perioperatório de pacientes submetidos à cirurgia limpa em um hospital universitário do Centro-Oeste brasileiro. MÉTODO: Estudo de coorte retrospectiva do tipo analítico, realizado por meio de 700 prontuários de pacientes, maiores ou igual a 18 anos, submetidos a procedimento cirúrgico limpo, de janeiro de 2008 a dezembro de 2010. Foi utilizado um formulário estruturado e previamente avaliado segundo as diretrizes nacionais. Os dados foram inseridos no Statistical Package For The Social Science versão 15 for Windows. A análise foi descritiva e multivariada, com testes qui-quadrado, Fisher e OR (odds ratio) como medidas de associação em variáveis com p<0,10. Foram consideradas estatisticamente significantes as associações com p<0,05. RESULTADOS: Quanto ao perfil sociodemográfico dos pacientes, 57,1% eram do sexo feminino, com idade entre 18 e 101 anos; 39,3% apresentavam comorbidades; 74,5%, com ASA ≤II. Quanto à especialidade cirúrgica, 29,9% ortopédica e 19,9% vascular. Inconformidades nos indicadores foram encontradas em 64,6%. Aspectos como o tempo de internação pré-operatória, o método usado para tricotomia, a duração da profilaxia antimicrobiana, o controle glicêmico em diabéticos, o controle térmico e o registro de inspeção das caixas cirúrgicas foram considerados não adequados. Os preditores para infecção do sítio cirúrgico pela análise univariada foram: sexo masculino, portador de doença crônica, etilismo e tabagismo, infecção à distância, tempo de internação pré-operatória > 5 dias, ASA ≥ III, tricotomia e a profilaxia antimicrobiana; os fatores independentes foram: ser portador de doença crônica, infecção à distância e tricotomia com lâmina de barbear. A taxa de infecção foi de 10%. A especialidade cirúrgica que apresentou maior índice de infecção foi a vascular, com 25,9%. O Staphylococcus aureus resistente à meticilina foi o agente etiológico de maior evidência. CONCLUSÃO: Concluiu-se que o serviço atende, parcialmente, os indicadores de processo para a prevenção da infecção do sítio cirúrgico no perioperatório de cirurgias limpas, em conformidade com os princípios do programa Cirurgias Seguras Salvam Vidas.

Beneš J.: HEMODYNAMIKA V ČASNÉ FÁZI KRITICKÝCH STAVŮ A PERIOPERAČNÍ MEDICÍNĚ - Využití méně invazivních monitorovacích prostředků k cílené hemodynamické péči ABSTRACT Hemodynamic instability occurs very often in critically ill patients and during the perioperative period. Insufficiency in the preload, contractility and afterload contribute in major part to this phenomenon. Hemodynamic monitoring allows clinicians to recognize and to intervene early the underlying cause. Due to new technologies development in recent years it is possible to provide continuous monitoring of hemodynamic parameters with diminished invasivity. Hemodynamic optimization and goal directed therapy show treatment benefit in some groups of critically ill patients and mainly during the perioperative period. Aim of hemodynamic optimizations is to attain the best obtainable hemodynamic conditions with use of fluid loading and inotropic support. In many studies in recent years goal-directed therapy was associated with morbidity and mortality reduction. According to the results of our clinical research hemodynamic optimization using stroke volume variation and minimally invasive device based on the pressure wave analysis is feasible and show the same results as other works with more invasive devices. Key words Hemodynamic monitoring,...

O conceito de segurança nasceu com o homem primitivo ao lutar diariamente para sobreviver contra os ataques de predadores. Com o passar dos anos foram surgindo parâmetros de sobrevivência e segurança em quase todas as atividades de trabalho. Na área de saúde e de enfermagem este tema tem mobilizado esforços das organizações de saúde no sentido de evitar falhas nos processos de cuidado que possam causar eventos adversos aos pacientes. Trata-se de uma pesquisa exploratória, descritiva, com abordagem qualitativa, com o objetivo de analisar a aplicação do checklist da cirurgia segura no centro cirúrgico para a segurança do paciente. O estudo foi conduzido utilizando-se a técnica de grupos focais e métodos fotográficos de pesquisa, na perspectiva do pensamento ecológico restaurativo, entre o período de março e junho de 2014. As informações foram organizadas com o recurso do programa NVivo 10 e submetidas à análise de conteúdo do tipo temática, surgiram três categorias: Checklist para a segurança do paciente: ainda um desafio, Motivos da não adesão ao checklist da Cirurgia Segura, Etapas do Checklist. Os resultados ressaltam que o checklist é de suma importância e contribui como uma barreira para prevenir possíveis erros de lateralidade do procedimento cirúrgico e de troca de paciente na sala operatória, além de assegurar a correta identificação do paciente no momento do preparo para ingressar no centro cirúrgico. Nos debates foi ressaltado que o grupo pesquisado conhece o instrumento para a realização do checklist da cirurgia segura, porém, refere ter dificuldades para o preenchimento do mesmo, principalmente devido à necessidade de agilizar o processo e encaminhar rapidamente o paciente à sala de cirurgia. Foi percebido que existem falhas no preenchimento do protocolo da cirurgia segura, em algumas situações o instrumento é preenchido antes de iniciar a cirurgia ou após o término da mesma. É fundamental envolver e comprometer as equipes médicas para a aplicação do checklist da cirurgia segura, além de (re) orientar e empoderar as equipes de enfermagem, a fim de seguir corretamente o protocolo da lista de verificação instituída, minimizando situações de desvalorização e ridicularização da rotina. A aplicação de maneira correta desse protocolo contribui para o reconhecimento assistencial das equipes na instituição. A natureza participativa do método de pesquisa fotográfico restaurativo oportunizou o engajamento dos profissionais do campo de estudo e possibilitou implementar muitas melhorias, a partir de sugestões e propostas dos mesmos. Outro aspecto que merece ser destacado, diz respeito ao duplo papel de pesquisador e gestor da instituição investigada, que permitiu traduzir os conhecimentos produzidos a partir do estudo em ações no cenário da prática assistencial, transformando-o em um ambiente mais seguro para o paciente. / The security concept was born with primitive man to fight daily to survive against attacks by predators. Over the years arose survival and safety parameters in almost all work activities. In the health and nursing area this theme has mobilized efforts of health organizations to avoid gaps in care processes that may cause adverse events to patients. This is an exploratory, descriptive research with a qualitative approach, in order to analyze the application of the safe surgery checklist in the operating room for patient safety. The study was conducted using the technique of focus groups and photographic research methods from the perspective of restorative ecological thinking, in the period between March and June 2014. The information was organized with the use of NVivo program 10 and subjected to analysis of thematic content, there were three categories: Checklist for patient safety: still a challenge, Reasons for non-adherence to the Safe Surgery Checklist, Steps Checklist. The results emphasize that the checklist is very important and contributes as a barrier to prevent possible errors laterality of the surgical procedure and patient exchange in the operating room, and ensure the correct identification of the patient while preparing to enter the operating room. In the discussions it was stressed that the group researched know the instrument for the achievement of the safe surgery checklist, however, concerns have trouble completing it, mainly because of the need to streamline the process and quickly refer the patient to the operating room. It was noticed that there are errors in the completion of the safe surgery protocol, in some situations the instrument is filled before starting surgery or after the same. It is essential to involve and engage the medical teams to the application of the safe surgery checklist, and (re) direct and empower the nursing staff in order to properly follow the established checklist protocol, minimizing devaluation situations and ridicule of routine. The application correctly this protocol contributes to the recognition of care teams in the institution. The participatory nature of the photographic restorative search method provided an opportunity to engage the professional field of study and made it possible to implement many improvements from suggestions and proposals from them. Another aspect that deserves to be highlighted concerns the dual role of researcher and manager of the investigated institution, which translated the knowledge produced from the study into shares in the care practice setting, turning it into a safer environment for the patient. / El concepto de seguridad nació con el hombre primitivo que luchar a diario para sobrevivir contra los ataques de los depredadores. Con los años surgieron parámetros de supervivencia y seguridad en casi todas las actividades de trabajo. En el área de la salud y de enfermería este tema ha movilizado esfuerzos de las organizaciones de salud para evitar lagunas en los procesos de atención que pueden causar efectos adversos a los pacientes. Se trata de una investigación exploratoria, descriptiva con enfoque cualitativo, con el fin de analizar la aplicación de la lista de verificación de la seguridad quirúrgica en el quirófano para la seguridad del paciente. El estudio se realizó mediante la técnica de grupos focales y los métodos de investigación fotográficos desde la perspectiva del pensamiento ecológico restaurativa, en el período comprendido entre marzo y junio de 2014. La información se organizó con el uso del programa NVivo 10 y se sometió a análisis de contenido temático, había tres categorías: Lista de verificación para la seguridad del paciente: sigue siendo un reto, Razones para la no adhesión a la Lista de verificación de cirugía segura, Pasos Lista de verificación. Los resultados ponen de manifiesto que la lista es muy importante y contribuye como una barrera para evitar posibles errores de lateralidad del procedimiento y paciente intercambio quirúrgica en el quirófano, y garantizar la correcta identificación del paciente mientras se preparan para entrar en la sala de operaciones.
