Empleo de antibióticos en cirugía electiva en el adulto mayor / Antibiotic Use for Elective Surgery in the Older Adult

Introducción: Los pacientes quirúrgicos geriátricos tienen afectación funcional y enfermedades asociadas, lo cual aumenta su riesgo quirúrgico con la edad. Objetivo: Determinar el comportamiento del uso de los antibióticos en pacientes geriátricos que requieren cirugía electiva atendidos en el Hospital Vladimir Ilich Lenin del 2018 al 2022. Métodos: Se realizó un estudio descriptivo, observacional, analítico y transversal a pacientes intervenidos por cirugía electiva con tratamiento con antibiótico. Los datos se obtuvieron de las historias clínicas y la entrevista aplicada. Se analizaron variables como edad, sexo, enfermedades asociadas, diagnóstico preoperatorio, tiempo quirúrgico, complicaciones, evolución, filtrado glomerular y dosis antibiótica perioperatoria. Resultados: El empleo de antibióticos fue más utilizado en los grupos de edades de 60 a 64 años y el sexo femenino; las comorbilidades que predominaron fueron la diabetes mellitus, la hipertensión arterial y la cardiopatía isquémica. Los motivos de consulta más frecuentes fueron por litiasis vesicular y por hernias dentro del grupo ASA I de la American Society of Anesthesiologists. Los antibióticos fundamentales fueron con dosis ajustada. Conclusiones: Se necesita de un trabajo diferenciado en cuanto a la atención al adulto mayor. La utilización de un protocolo o algoritmo de trabajo es necesario en la práctica diaria, sobre todo ante la necesidad de una cirugía electiva(AU)

Introduction: Geriatric surgical patients have functional impairment and associated diseases, which increases their surgical risk with age. Objective: To determine the behavior of antibiotic use in geriatric patients requiring elective surgery attended at Hospital Vladimir Ilich Lenin Hospital from 2018 to 2022. Methods: A descriptive, observational, analytical and cross-sectional study was conducted on patients undergoing elective surgery with antibiotic treatment. The data were obtained from medical records and the applied interview. The analyzed variables included age, sex, associated diseases, preoperative diagnosis, surgical time, complications, evolution, glomerular filtration and perioperative antibiotic dose. Results: Antibiotic use was more frequent in the age group 60 to 64 years and in the female sex; the most frequent comorbidities were diabetes mellitus, arterial hypertension and ischemic heart disease. The most frequent reasons for consultation were vesicular lithiasis and hernias within the ASA I group of the American Society of Anesthesiologists. The fundamental antibiotics were adjusted by doses. Conclusions: An individualized work is needed in terms of care of the older adult. The use of a working protocol or algorithm is necessary in daily practice, especially when elective surgery is required(AU)

Análisis de los factores de riesgo para complicaciones en la colecistitis aguda litiásica. Deconstrucción de las Tokyo Guidelines / Risk factors for complications in acute calculous cholecystitis. Deconstruction of the Tokyo Guidelines

Introducción: Analizar los factores de riesgo de complicaciones para colecistitis aguda litiásica confrontándolos a las Tokyo Guidelines. Métodos: Estudio retrospectivo de 963 pacientes con colecistitis aguda durante 5 años. Se seleccionaron 725 pacientes con colecistitis aguda litiásica «pura», y analizaron 166 variables mediante regresión logística, incluyendo todos los factores de riesgo de las Tokyo Guidelines. Mediante el Propensity Score Matching, se seleccionaron subpoblaciones comparables de 75 pacientes y se analizaron las complicaciones según el tratamiento realizado (quirúrgico/no quirúrgico) y se utilizó el fallo en el rescate como indicador de calidad del tratamiento en la colecistitis aguda litiásica. Resultados: La mediana de edad fue de 69 años (RIQ 53-80). La mayoría de los pacientes fueron ASA II o III (85,1%). El 21% de las colecistitis fueron leves, el 39% moderadas y el 40% graves. Se colecistectomizó al 95% de los pacientes. El 43% de los pacientes se complicaron y la mortalidad fue del 3,6%. Los factores de riesgo independientes para complicaciones graves fueron ASA>II, tumor sólido sin metástasis e insuficiencia renal. El fallo en el rescate (8%) fue mayor en los no operados (32% vs. 7%; P=0,002). Tras realizar el Propensity Score Matching, la tasa de complicaciones graves fueron comparables entre operados y no operados (48,5% vs. 62,5%; P=0,21). Conclusiones: La colecistectomía precoz es el tratamiento preferente para la colecistitis aguda litiásica. Solo tres de los factores de las Tokyo Guidelines son variables independientes para predecir complicaciones graves. El fallo en el rescate es mayor en los pacientes no intervenidos quirúrgicamente. (AU)

Introduction: To challenge the risk factors described in Tokyo Guidelines in acute calculous cholecystitis. Methods: Retrospective single center cohort study with 963 patients with acute cholecystitis during a period of 5 years. Some 725 patients with a “pure” Acute calculous cholecystitis were selected. The analysis included 166 variables encompassing all risk factors described in Tokyo Guidelines. The Propensity Score Matching method selected two subgroups of patients with equal comorbidities, to compare the severe complications rate according to the initial treatment (Surgical vs. non-surgical). We analyzed the failure-to-rescue as a quality indicator in the treatment of acute calculous cholecystitis. Results: The median age was 69 years (IQR 53-80). 85.1% of the patients were ASA II or III. The grade of the acute calculous cholecystitis was mild in a 21%, moderate in 39% and severe in 40% of the patients. Cholecystectomy was performed in 95% of the patients. The overall complications rate was 43% and the mortality was 3.6%. The Logistic Regression model isolated 3 risk factor for severe complication: ASA>II, cancer without metastases and moderate to severe renal disease. The failure-to-rescue (8%) was higher in patients with non-surgical treatment (32% vs. 7%; P=.002). After Propensity Score Matching, the number of severe complications was similar between Surgical and Non-Surgical treatment groups (48.5% vs 62.5%; P=.21). Conclusions: The recommended treatment for acute calculous cholecystitis is the laparoscopic cholecystectomy. Only three risk factors from the Tokyo Guidelines list appeared as independent predictors of severe complications. The failure-to-rescue is higher in non-surgically treated patients. (AU)

Impacto del síndrome de iris flácido intraoperatorio (IFIS) en cirugía de cataratas mediante facoemulsificación: análisis de 622 casos / Impact of intraoperative floppy IRIS syndrome in cataract surger by phacoemulsification: Analysis of 622 cases

Introducción Los síndromes de pupila estrecha, incluido el síndrome de iris flácido intraoperatorio (IFIS), aumentan el riesgo de complicaciones durante la cirugía de cataratas si no se realiza una correcta planificación quirúrgica. La tamsulosina se asocia a un incremento muy significativo del riesgo de IFIS, debido a la inactivación prolongada de los receptores alfa-1 adrenérgicos en la fibra muscular lisa del iris. Material y métodos Estudio prospectivo observacional unicéntrico, llevado a cabo en el Hospital de l’Esperança - Parc de Salut Mar.ResultadosSe incluyeron 622 ojos de 502 pacientes, de los cuales 337 (62%) eran mujeres. La media de edad de la muestra era de 74,8 años. Se observaron 61 casos de IFIS (11%), de los cuales 13 recibían tratamiento con tamsulosina y uno con doxazosina. Se observaron 23 casos de IFIS en pacientes mujeres. La ratio mujer:hombre fue de aproximadamente 1:3. Se observaron 19 casos (3%) de IFIS severo, de los cuales 6 recibían tratamiento con alfa-antagonistas, sin correlación estadísticamente significativa.La media del tiempo quirúrgico fue de 13,80min (desviación estándar [DE]: 4,01min) en pacientes sin IFIS y de 16,93min (DE: 4,32min) en pacientes con IFIS. La relación entre la duración del procedimiento quirúrgico en minutos y la presencia de IFIS fue estadísticamente significativa, aplicando un test t-Student «a dos colas» o bilateral con un p valor de 0,01. Conclusión Independientemente del grado de severidad, el diagnóstico de IFIS alarga el tiempo quirúrgico en cirugía de cataratas. Esto supone otra evidencia más que apoya la utilización de tratamientos antagonistas adrenérgicos menos alfa-1 selectivos que la tamsulosina o la realización de la cirugía de cataratas antes de iniciar dichos tratamientos. (AU)

Background Small pupil syndromes, including intraoperative-floppy iris syndrome (IFIS), increase the risk of complications during cataract surgery if proper surgical planning is not performed. Tamsulosin is associated with a very significant increase in the risk of IFIS, due to the prolonged inactivation of alpha-1 adrenergic receptors in the smooth muscle fiber of the iris. Material and methods Single-center prospective observational study, carried out at the Hospital de l’Esperança – Parc de Salut Mar.ResultsSix hundred and twenty-two eyes of 502 patients were included, of which 337 (62%) were women. The mean age of the sample is 74.8 years. Sixty-one cases of IFIS (11%) were observed, of which 13 received treatment with Tamsulosin and 1 with Doxazosin. Twenty-three cases of IFIS were observed in female patients. The female:male ratio was approximately 1:3. Nineteen cases (3%) of severe IFIS were observed, of which 6 received treatment with alpha-antagonists, with no statistically significant correlation.The mean surgical time was 13.80min (standard deviation – SD: 4.01min) in patients without IFIS and 16.93min (SD: 4.32min) in patients with IFIS. The relationship between the duration of the surgical procedure in minutes and the presence of IFIS was statistically significant, applying a ‘two-tailed’ or bilateral t-Student test with a p value of 0.01. Conclusion Regardless of the degree of severity, the diagnosis of IFIS lengthens the surgical time in cataract surgery. This represents yet another piece of evidence that supports the use of less selective alpha-1 adrenergic antagonist treatments than tamsulosin or the performance of cataract surgery before starting these treatments.

Abordaje transcaval en reemplazo valvular aórtico percutáneo: primer caso en Costa Rica / Transcaval approach in valve replacement Percutaneous Aortic Surgery: First Case in Costa Rica

La estenosis aórtica severa sintomática que se presenta en pacientes de alto o mediano riesgo quirúrgico puede ser abordada de manera percutánea con reemplazos valvulares aórticos transcateter. Existe sólida evidencia de resultados favorables en estos pacientes con un perfil de seguridad adecuado. El abordaje transfemoral es el más utilizado y ha demostrado ser más seguro en comparación a los abordajes torácicos. Sin embargo, desde mitades de la década pasada el abordaje transcaval se ha convertido en una opción en los pacientes que presentan un riesgo quirúrgico alto y que presentan una vasculatura inadecuada para un abordaje transfemoral seguro. Presentamos el caso de un paciente de 65 años en quien se empleó este abordaje dado a su alto riesgo quirúrgico e inaccesibilidad para realizar un abordaje transfemoral.

Severe symptomatic aortic stenosis in patients with high surgical risk can be addressed percutaneously with transcatheter aortic valve replacement (TAVR). There is solid evidence of favorable results with an adequate safety profile in these patients. The transfemoral approach is the most widely used and has shown to be safer compared to thoracic approaches. Though, since the middle of the last decade, the transcaval approach has become an option in patients who present a high surgical risk and who have inadequate vasculature for a safe transfemoral approach. We present the case of a 65-year-old patient in whom this approach was preferred due to his high surgical risk and inaccessibility to perform a transfemoral approach.

Introducción: La atención estomatológica integral al paciente de riesgo quirúrgico resulta un reto en la actualidad. El profesional de la estomatología necesita herramientas que permita profundizar en los riesgos quirúrgicos, entre esas herramientas puede contarse la correcta confección de historia clínica. Objetivo: Describir el comportamiento de la confección de historia clínica en los pacientes de riesgo quirúrgico en la Clínica Estomatológica "Salvador Allende". Métodos: Se revisaron 108 historias clínicas de todos los pacientes de riesgo quirúrgico ingresados en la consulta de estomatología general integral en el archivo de la Clínica "Salvador Allende" del municipio Cerro, La Habana, correspondientes a un periodo de tres meses. Resultados: Un 41,6 por ciento de pacientes presentó hipertensión arterial, seguidos de pacientes con dos o más enfermedades (37,0 por ciento). El 56,4 por ciento de las historias clínicas abordó sobre el uso de medicamentos para la enfermedad de base, los restantes acápites tuvieron bajos porcentajes en relación con el completamiento de la información. El 79,6 por ciento de los pacientes de riesgo recibieron tratamiento quirúrgico. Conclusiones: La enfermedad de riesgo más frecuente es la hipertensión arterial seguida por los pacientes con dos o más enfermedades. No se recogen los datos necesarios en la atención del paciente de riesgo quirúrgico y las propuestas plasmadas permitirán realizar cualquier ejercicio de la profesión de manera más eficaz y con menor riesgo(AU)

Introduction: Comprehensive dental care of surgical risk patients is a current challenge. Dental care professionals should have access to tools allowing them to expand their knowledge about possible surgical risks. Appropriately developed medical records are an example of such tools. Objective: To describe the process of development of medical records of surgical risk patients at Salvador Allende dental clinic. Methods: A total 108 medical records were reviewed, corresponding to all the surgical risk patients admitted to the general comprehensive dental care service of Salvador Allende dental clinic in the municipality of Cerro, Havana, in a three months' period. Results: Of the patients studied, 41.6 percent had arterial hypertension, followed by patients with two or more conditions (37.0 percent). It was found that 56.4 percent of the medical records contained information about the use of drugs for the underlying condition. The remaining items exhibited low percentages of data completion. 79.6 percent of the risk patients received surgical treatment. Conclusions: The most common risk condition is arterial hypertension, followed by patients with two or more diseases. The data required for the care of surgical risk patients are not recorded. The proposals put forth will make it possible to perform any professional practice in a more effective manner and with a lower level of risk(AU)

Mortality predictors in complicated patients after anatomical lung resection / Variables predictivas de muerte en pacientes complicados tras resección pulmonar anatómica

Introduction: Failure to rescue (FTR), defined as the mortality rate among patients suffering from postoperative complications, is considered an indicator of the quality of surgical care. The aim of this study was to investigate the risk factors associated with FTR after anatomical lung resections.Method: Patients undergoing anatomical lung resection at our center between 1994 and 2018 were included in the study. Postoperative complications were classified as minor (grade I and II) and major (grade IIIA to V), according to the standardized classification of postoperative morbidity. Patients who died after a major complication were considered FTR. A stepwise logistic regression model was created to identify FTR predictors. Independent variables included in the multivariate analysis were age, body mass index, cardiac, renal, and cerebrovascular comorbidity, ppoFEV1%, VATS approach, extended resection, pneumonectomy, and reintervention. A non-parametric ROC curve was constructed to estimate the predictive capacity of the model.Results: A total of 2.569 patients were included, of which 223 (8.9%) had major complications and 49 (22%) could not be rescued. Variables associated with FTR were: age (OR: 1.07), history of cerebrovascular accident (OR: 3.53), pneumonectomy (OR: 6.67), and reintervention (OR: 12.26). The area under the ROC curve was 0.82 (95% CI: 0.77–0.88).Conclusions: Overall, 22% of patients with major complications following anatomical lung resection in this series did not survive until discharge. Pneumonectomy and reintervention are the most significant risk factors for FTR. (AU)

Introducción: El fallo en el rescate (FTR) definido como la tasa de fallecimientos entre los pacientes que sufren una complicación postoperatoria, es considerado un indicador de la calidad de los cuidados quirúrgicos. El objetivo de este estudio es investigar los factores de riesgo asociados al FTR después de resecciones pulmonares anatómicas.Método: Se incluyeron en el estudio pacientes sometidos a resección pulmonar anatómica en nuestro centro entre 1994 y 2018. Las complicaciones postoperatorias se clasificaron en menores (grados I y II) y mayores (grados IIIa a V) según la clasificación estandarizada de morbilidad postoperatoria. Los casos que fallecieron tras una complicación mayor fueron considerados FTR. Se creó un modelo de regresión logística por pasos para identificar los factores predictores de FTR. Se consideraron variables independientes en el análisis multivariante la edad, índice de masa corporal, comorbilidad cardiaca, renal, cerebrovascular, VEF1ppo%, abordaje VATS, resección extendida, neumonectomía y reintervención. Se construyó una curva ROC no paramétrica para estimar la capacidad predictiva del modelo.Resultados: Se analizaron 2.569 pacientes. En total, 223 casos (8,9%) tuvieron complicaciones mayores y 49 (22%) no pudieron ser rescatados. Las variables asociadas con FTR fueron: edad (OR: 1,07), antecedente de ACV (OR: 3,53), neumonectomía (OR: 6,67) y reintervención (OR: 12,26). El área bajo la curva de la curva ROC fue 0,82 (IC 95%: 0,77–0,88).Conclusiones: 22% de los pacientes que presentan complicaciones mayores tras la resección pulmonar anatómica en esta serie no sobreviven al alta. La neumonectomía y la reintervención son los factores de riesgo más potentes para FTR. (AU)

Clasificación de pacientes especiales según sus requerimientos en la atención estomatológica / Classification of specials patients according their dentist attention requirements

Introducción: El paciente de riesgo quirúrgico es aquel susceptible a un posible daño que amenaza al individuo que será sometido a una intervención quirúrgica. Este tipo de paciente es llamado"paciente especial", o que presenta deficiencias y existen además otros conceptos donde pudiera estar implícito. Este paciente no es claramente identificado y esto hace más complicado unificar criterios que permitan llevar a cabo un el tratamiento estomatológico sin causar daños colaterales. Objetivo: Elaborar una clasificación de pacientes especiales según sus requerimientos en la atención estomatológica. Métodos: Investigación cualitativa. Se realizó revisión bibliográfica y se tomaron en consideración investigaciones previas de la autora principal para la confección de la propuesta de clasificación. Para evaluar la misma se utilizó el método Delphi, lo cual permitió llegar a opiniones de consenso de los expertos, quienes valoraron la propuesta como: inadecuada, poco adecuada, adecuada, bastante adecuada y muy adecuada. Resultados: Se expone la clasificación de pacientes especiales según requerimientos durante la atención estomatológica. Incluyó a cinco grupos. El grupo I, nombrado de riesgo quirúrgico, se subdividió en cinco subgrupos. Los expertos consideraron la clasificación propuesta como Bastante Adecuada(2) y Muy Adecuada (12). Conclusiones: La clasificación propuesta facilita al estomatólogo una atención diferenciada al paciente especial, donde se hace adecuaciones en el paciente de riesgo quirúrgico teniendo en cuenta las características más importantes de las enfermedades de base. La clasificación propuesta fue catalogada como aceptada(AU)

Introduction: Numerous definitions exist where the patient of surgical risk can be incorporate keeping in mind her definition that is possible damage that she threatens the individual that will be subjected to a surgical intervention, such as patient special, with deficiencies among other but it has not been find a classification of patient of risk surgery. It cannot allow indentify those and it is difficult the dentist treatment without systemic complication. Objective: To elaborate a classification proposal of specials patients according dentist attention requirements. Methods: it was qualitative research. It was carried out exhaustive bibliographical revision and it took in consideration previous investigations carried out by the main author, with this consideration the classification proposal was made. To evaluate the proposal it used the method Delphi, which allowed arriving to opinions of the experts' consent. It took into consideration different variables: Inadequate, Not Appropriate, Appropriate, Quite Appropriate and Very Appropriate. Results: The classification is exposed of patient special according dentist attention requirements, it included to five groups and the group I was subdivided, called surgical risk, in five subgroups. 100 percent experts considered the classification like Quite Appropriate and Very Appropriate 2 in the first categories and 12 in the second one. Conclusions: The proposed classification facilitates to the dentist an attention to the differentiated special patient with emphasis in surgical risk patients keeping in mind the most important characteristics in the base illnesses. The proposed classification was classified as having accepted(AU)

Segundas resecciones anatómicas en pacientes con resección anatómica previa / Second pulmonary anatomical lung resections in patients with previous anatomical resections

Resumen Introducción: Las segundas resecciones anatómicas son cada vez más frecuentes en el tratamiento de carcinomas pulmonares sincrónicos, metacrónicos y de metástasis pulmonares de origen extrapulmonar. Objetivo: Determinar si las segundas resecciones anatómicas pulmonares se asocian con un mayor riesgo de complicaciones posoperatorias comparadas con la primera intervención. Materiales y Método: Hemos analizado todos los pacientes sometidos a una segunda resección anatómica en nuestro centro entre octubre de 2000 y febrero de 2019. Las complicaciones fueron clasificadas en mayores y menores según la clasificación estandarizada de morbilidad posoperatoria de Clavien-Dindo. Se compararon las características clínicas y demográficas de los pacientes y la ocurrencia de complicaciones mayores tras la primera y la segunda intervención quirúrgica mediante la prueba T para muestras relacionadas y la prueba exacta de McNemar para las variables cuantitativas y categóricas, respectivamente. Resultados: Setenta y cinco pacientes fueron sometidos a una segunda resección anatómica. La prevalencia de complicaciones globales y mayores tras la primera intervención fue del 26,7% y el 4% frente al 34,7% y al 6,7% tras la segunda intervención (p = 0,362 y p = 0,727, respectivamente). Las segundas resecciones pulmonares ipsilaterales se asociaron con un 16,7% de complicaciones mayores y los procedimientos consistentes en completar la neumonectomía con un 25%. Conclusión: Las segundas resecciones anatómicas pulmonares no se asocian con un mayor riesgo de complicaciones posoperatorias comparadas con la primera intervención. Sin embargo, las segundas resecciones ipsilaterales y las resecciones que impliquen completar la neumonectomía se asocian con riesgo significativamente superior de complicaciones mayores posoperatorias.

Introduction: Second anatomical resections are becoming more frequent in the treatment of synchronous, metachronous and pulmonary metastases of extrapulmonary origin. Aim: The objective of this study is to determine whether second pulmonary anatomical resections are associated with an increased risk of postoperative complications compared to the first intervention. Materials and Method: We have analyzed all patients undergoing a second anatomical resection in our center between October 2000 and February 2019. Complications were classified in major and minor according to the standardized Clavien-Dindo postoperative morbidity classification. The clinical and demographic characteristics of the patients and the occurrence of major complications after the first and second surgical intervention were compared using the T test for related samples and the McNemar exact test for quantitative and categorical variables, respectively. Results: Seventy-five patients underwent a second anatomic resection. The prevalence of global and major complications after the first intervention was 26.7% and 4% compared to 34.7% and 6.7% after the second intervention (p = 0.362 and p = 0.727, respectively). Second ipsilateral lung resections were associated with 16.7% of major complications and procedures consisting of completing pneumonectomy with 25%. Conclusion: Second lung anatomical resections are not associated with an increased risk of postoperative complications compared to the first intervention. However, second ipsilateral resections and resections that involve completing pneumonectomy are associated with a significantly higher risk of major postoperative complications.

SEVE project (Surgical Expertise Validity Evaluation) risk adjusted quality by standard data.

The SEVE project (Surgical Expertise Validity Evaluation) is a collaborative effort of the AEC (Spanish Association of Surgeons) and the Section of Surgery of the European Union of Medical Specialists (UEMS) that aims to develop a model and an on line application that can be used to evaluate surgical complications. The aim is to identify the optimal results that can be obtained in each intervention, in order to present them as a reference for our usual practice (benchmarking).

Mortality predictors in complicated patients after anatomical lung resection.

INTRODUCTION: Failure to rescue (FTR), defined as the mortality rate among patients suffering from postoperative complications, is considered an indicator of the quality of surgical care. The aim of this study was to investigate the risk factors associated with FTR after anatomical lung resections. METHOD: Patients undergoing anatomical lung resection at our center between 1994 and 2018 were included in the study. Postoperative complications were classified as minor (grade I and II) and major (grade IIIA to V), according to the standardized classification of postoperative morbidity. Patients who died after a major complication were considered FTR. A stepwise logistic regression model was created to identify FTR predictors. Independent variables included in the multivariate analysis were age, body mass index, cardiac, renal, and cerebrovascular comorbidity, ppoFEV1%, VATS approach, extended resection, pneumonectomy, and reintervention. A non-parametric ROC curve was constructed to estimate the predictive capacity of the model. RESULTS: A total of 2.569 patients were included, of which 223 (8.9%) had major complications and 49 (22%) could not be rescued. Variables associated with FTR were: age (OR: 1.07), history of cerebrovascular accident (OR: 3.53), pneumonectomy (OR: 6.67), and reintervention (OR: 12.26). The area under the ROC curve was 0.82 (95% CI: 0.77-0.88). CONCLUSIONS: Overall, 22% of patients with major complications following anatomical lung resection in this series did not survive until discharge. Pneumonectomy and reintervention are the most significant risk factors for FTR.

¿Un nuevo factor de riesgo quirúrgico: la polución del aire. ¿Lo debemos tener en cuenta? / A new surgical risk factor: air pollution. Should we consider it as such?

La polución atmosférica incrementa la mortalidad global por cualquier causa. En especial la debida a causas de origen respiratorio y cardiovascular. Los pacientes que ingresan por una isquemia miocárdica aguda hacen con más frecuencia insuficiencia cardiaca aguda en aquellos pacientes en los que se encuentran partículas de polución en sus alveolos. Su significado entre los pacientes que se operan de patologías graves o están muy frágiles o con mucha comorbilidad está sin estudiar. Se plantea formar un comité de expertos que verifique en episodios de polución atmosférica en que proporción ésta influye en los resultados. Y si es así, incorporarlo en los predictores de riesgo quirúrgico. Más adelante se deben proponer medidas de como evitarlo y tratarlo. (AU)

Air pollution increases global mortality from any cause. Especially due to causes of respiratory and cardiovascular origin. Patients admitted for acute myocardial ischemia more frequently experience acute heart failure in those patients in whom pollution particles are found in their alveoli. Its significance among patients who undergo surgery for serious pathologies or who are very fragile or with a lot of comorbidity has not been studied. It is proposed to form a committee of experts to verify in episodes of atmospheric pollution in what proportion it influences the results. And if so, incorporate it into the predictors of surgical risk. Later, measures should be proposed on how to avoid it and treat it. (AU)
