Introducción: La tasa de complicaciones infecciosas posoperatorias se eleva en el paciente quirúrgico, entre otras razones, debido a que con elevada frecuencia, resulta insuficiente el conocimiento sobre la génesis de los factores que las provocan. Se realizó una revisión documental sobre el tema durante 2020 y 2021. Fueron consultadas las bases de datos Web of Science, PubMed, Medline, Cochrane, SciElo así como el motor de búsqueda Google académico. Se seleccionaron 32 artículos en idiomas inglés y español. Objetivo: Analizar los aspectos fundamentales concernientes a la génesis de las infecciones posoperatorias. Desarrollo: Las infecciones del sitio quirúrgico constituyen el 25 % de las asociadas a la atención de salud. A pesar de todas las medidas para su prevención, no se ha logrado su desaparición, lo que conlleva una elevada morbilidad, aumento de los costos de hospitalización, de la estadía hospitalaria y uso de antibióticos de última generación. Esto puede explicarse por la aparición de microorganismos resistentes a los antibióticos y el aumento de pacientes quirúrgicos de edad avanzada e inmunodeprimidos por enfermedades asociadas, con inclusión de los trasplantados, con injertos o prótesis. Conclusiones: Los microorganismos que provocan las infecciones posquirúrgicas, pertenecen predominantemente a la microbiota presente en el lugar de la incisión. Los factores del enfermo, de la técnica quirúrgica y los relacionados con la hospitalización, juegan roles importantes en su aparición.

Introducción: La mayor expectativa de vida en la población general ha aumentado la prevalencia de las enfermedades del sistema eléctrico de conducción cardíaca y, con ello, la indicación e implante de marcapasos. Objetivo: Identificar los factores de riesgo de infección tras la implantación de marcapasos permanente. Métodos: Se realizó un estudio analítico, de casos y controles, de los 192 pacientes, a los cuales se les implantó marcapasos permanente entre enero de 2017 y diciembre de 2019 en el Servicio de Cardiología del Hospital Clinicoquirúrgico Docente Celia Sánchez Manduley de la provincia de Granma. El grupo de estudio estuvo integrado por los 38 que presentaron infección tras ese proceder y por cada paciente de este grupo se escogieron 2, que también recibieron este dispositivo y no tuvieron infección, que formaron parte de los controles. Se estudiaron variables dependientes del paciente, del dispositivo, del proceder y de los exámenes practicados. Se utilizaron el test de Fisher y la prueba de la X2 para variables cualitativas, según correspondiera y la prueba de la T de Student para las cuantitativas. Para determinar los factores de riesgo de infección se utilizó un modelo de regresión logística. Resultados: Prevaleció el sexo masculino (60,5 %) y la media de edad fue de 76,1 años. Como factores de riesgo predominaron el uso de antiagregantes y anticoagulantes, el antecedente de diabetes mellitus y las cifras de glucemia mayores de 8,0 mmol/L. Conclusiones: Existen factores de riesgo de infección modificables, por lo que constituye un gran reto médico actuar sobre estos para prevenir complicaciones letales para la vida.

Introduction: The higher life expectancy in the general population has increased the prevalence of diseases of the heart conduction of electric system and, with it, the indication and implant of pacemaker. Objective: To identify the risk factors of infection after the permanent pacemaker implantation Methods: A cases and controls analytic study of 192 patients, to whom a permanent pacemaker was implanted between January, 2017 and December, 2019 was carried out in the Cardiology Service of Celia Sánchez Manduley Teaching Clinical Surgical Hospital from Granma. The study group was integrated by the 38 patients that presented infection after that procedure and every each patient of this group 2 were chosen that also received this device and had no infection that were part of the control group. The variables dependent on the patient, the device, the procedure and the exams were studied. The Fisher test and the chi-square test were used for qualitative variables, as corresponded and the Student t test for the quantitative variables. To determine the risk factors of infection a model of logistical regression was used. Results: The male sex prevailed (60.5%) and the mean age was of 76.1 years. As risk factors the use of antiagregants and anticoagulants, history of diabetes mellitus and glucemia figures higher than 8.0 mmol/L prevailed. Conclusions: There are modifiable risk factors of infection, what constitutes a great challenge in medicine to influence on these factors to prevent lethal complications for life.

A pesar de los avances de las técnicas quirúrgicas, anestésicas, microbiológicas, así como de la ingeniería genética y la biotecnología, las infecciones constituyen el enemigo invisible del paciente operado. La aparición de infección nosocomial en el periodo posoperatorio constituye una complicación frecuente que, independientemente de todas las medidas de prevención y control, aumenta la morbilidad y mortalidad posquirúrgicas; pues, además de comprometer los resultados de las intervenciones, favorecen la aparición de otras complicaciones, en ocasiones fatales, con repercusiones socioeconómicas muy desfavorables para el enfermo y las instituciones sanitarias. Por esas razones, la revisión sobre este tema nunca pierde actualidad, dado su origen multifactorial, diversidad de localizaciones y variedad de gérmenes que las provocan. Así, este artículo pretende contribuir a su prevención, diagnóstico precoz, tratamiento oportuno y adecuado, según las buenas prácticas médicas y quirúrgicas.In spite of the advances of the surgical, anesthetic and microbiologic techniques, as well as of the genetic engineering and the biotechnology, infections constitute the invisible enemy of the operated patient. The occurrence of nosocomial infection in the postoperative period constitutes a frequent complication which, independently from all the prevention and control measures, increases the postsurgical morbidity and mortality, as besides compromising the results of the interventions, they favor the appearance of other complications, occasionally fatal, with very unfavorable socioeconomic repercussions for the sick person and the health institutions. For these reasons, the review on this topic never loses updating, given its multifactor origin, diversity of localizations and variety of germs provoking them. Thus, this work seeks to contribute to its prevention, early diagnosis, opportune and appropriate treatment, according to the good medical and surgical practices.

Introducción: la contaminación bacteriana es el requisito indispensable para la aparición de las infecciones posoperatorias, con repercusiones socioeconómicas desfavorables, las cuales aumentan el consumo de antimicrobianos. Objetivo: identificar diferentes factores relacionados con la utilización de antibióticos en pacientes con infecciones posquirúrgicas. Métodos: se realizó un estudio descriptivo, observacional y transversal acerca de la utilización de antibióticos en 207 pacientes expuestos a cirugías mayores, que presentaron infecciones posoperatorias, atendidos en el Servicio de Cirugía General del Hospital Provincial Docente "Saturnino Lora" de Santiago de Cuba durante el trienio 2008-2010. Resultados: predominaron las infecciones incisionales superficiales, seguidas de las localizadas en órgano y espacio. En el período preoperatorio se utilizaron antibióticos en las dos terceras partes de la serie y en el posoperatorio, en todos los que sufrieron esta complicación. Los estudios microbiológicos alcanzaron una positividad de 96,3 % y los gérmenes más comúnmente aislados fueron gramnegativos: Klebsiella, Escherichia coli y Acinetobacter baumannii. Conclusiones: la política del uso racional de antibióticos con fines profilácticos y terapéuticos, debe relacionarse con la circulación de gérmenes intrahospitalarios acorde con el mapa bacteriológico y el patrón de resistencia a fin de implementar un protocolo estandarizado para su aplicaciónIntroduction: bacterial contamination is the essential requirement for the occurrence of postoperative infections, with adverse social and economic implications, thus increasing the use of antibiotics. Objective: to identify different factors related to the use of antibiotics in patients with postoperative infections. Methods: a descriptive, observational and cross-sectional study on the use of antibiotics was carried out in 207 patients, who underwent major surgery and presented with postoperative infections, attended in the Department of General Surgery of "Saturnino Lora" Provincial Teaching Hospital of Santiago de Cuba during the triennium 2008-2010. Results: superficial incisional infections predominated, followed by those located in organ and space. In the preoperative period antibiotics were used in two-thirds of the series and in the postoperative period in all who had this complication. Microbiological studies had 96.3% of positivity and the most commonly isolated germs were: Klebsiella, Escherichia coli and Acinetobacter baumannii. Conclusions: the occurrence of postoperative infections is related to the proliferation of Gram-negative organisms. The policy of rational use of antibiotics with prophylactic and therapeutic purposes, related to the circulation of hospital germs and resistance pattern, is considered adequate, but a standardized protocol should be implemented for its application.

Introducción: la contaminación bacteriana es el requisito indispensable para la aparición de las infecciones posoperatorias, y a pesar de los avances de las técnicas quirúrgicas, anestésicas y de la biotecnología, continúan asediando al paciente operado, aumentan su morbilidad y mortalidad, y tienen repercusiones socioeconómicas desfavorables. Métodos: se realizó un estudio observacional, descriptivo y transversal de 103 pacientes ingresados y operados de cirugías mayores que presentaron infecciones posoperatorias en el servicio de cirugía general del Hospital Provincial Docente "Saturnino Lora", de Santiago de Cuba, en el año 2008, según variables seleccionadas. Objetivos: describir las principales características de las infecciones posquirúrgicas relacionadas con su localización, gérmenes aislados, antibioticoterapia utilizada y estadía hospitalaria, así como determinar la mortalidad por esta causa. Resultados: las localizaciones más frecuentes de las infecciones posoperatorias fueron: incisional superficial, respiratorias y de órgano/espacio para las intervenciones sucias y contaminadas. La media de estadía hospitalaria de la serie se elevó a 15,2 días. La mayoría de los gérmenes aislados fueron gram negativos, sensibles a los antibióticos de primera línea utilizados. Fallecieron 6 pacientes (5,8 %): 5 por sepsis y uno por tromboembolismo pulmonar. Conclusiones: el grado de contaminación bacteriana de la intervención es lo más significativo para la aparición de la infección posoperatoria, independiente de su localización. La política de utilización de antimicrobianos debe correlacionarse con la sensibilidad de los gérmenes aislados en el mapa bacteriológico de cada unidad asistencial. Las medidas preventivas deben comenzar en el preoperatorio, continuar a través de la intervención, y prolongarse en el posoperatorio, por las repercusiones socioeconómicas desfavorables de esta temible complicación posquirúrgica.Introduction: bacterial contamination is the essential requirement for appearance of postoperative infections and despite the advances of surgical, anesthetic techniques and of the biotechnology, still remains involving to the patient operated on, increasing its morbidity and mortality and unfavourable socioeconomic repercussions. Methods: a cross-sectional, descriptive and observational study was conducted in 103 patients admitted and operated on of major surgeries with postoperative infections in the general surgery service of the "Saturnino Lora" Teaching Provincial Hospital of Santiago de Cuba province over 2008, according to the selected variables. Objectives: to describe the major features of postsurgical infections related to its location, germs isolated, antibiotic-therapy used and hospital stay, as well as to determine the mortality due to this cause. Results: the more frequent locations of postoperative infections were: superficial incision, respiratory and of organ/space for the dirty and contaminated interventions. The mean of the hospital stay of the series increased to 15.2 days. Most of the germs isolated were gram-negative, sensitive to first line antibiotics used. Six patients deceased (5.8 %): 5 due to sepsis and one due to pulmonary thromboembolism . Conclusions: the level of bacterial contamination of the intervention is the more significant for the appearance of the postoperative infection, independent of its location. The politics for the antimicrobials use must to be correlated with the sensitivity of germs isolated in the bacteriological map of each assistance unit. The preventive measures must to begin in the preoperative period, over the intervention and to continue in the postoperative one due to the socioeconomic unfavourable repercussions of this fearsome postsurgical complication.

Introducción: la génesis de las infecciones posquirúrgicas es multifactorial. Existen estudios internacionales que evidencian los diversos factores predictivos relacionados con la aparición de estas complicaciones, las que todavía afectan a un número considerable de pacientes intervenidos, todo lo cual justifica el interés en la realización de este trabajo. Objetivo: describir el comportamiento de algunos de los factores predictivos relacionados con la aparición de las infecciones posoperatorias en nuestro medio. Métodos: se realizó un estudio observacional, descriptivo y transversal de los pacientes ingresados y operados que presentaron infecciones posquirúrgicas en el servicio de cirugía general del Hospital Provincial Docente "Saturnino Lora" de Santiago de Cuba, durante el año 2008, según posibles factores predictivos seleccionados. Resultados: con relación al grado de contaminación, la tasa global de infección posoperatoria y la de heridas limpias estuvo en límites universalmente aceptados, aunque fueron más elevadas en las intervenciones urgentes, sucias y contaminadas para las localizadas en el sitio quirúrgico, así como en enfermos con estado físico preoperatorio según la American Society of Anaesthesiology (ASA) ASA II Y ASA III, con independencia de su estado nutricional y el tiempo quirúrgico en que se efectuaron las intervenciones. Conclusiones: las tasas de infecciones posquirúrgicas aumentaron en la medida en que fueron desfavorables las condiciones bajo las que se efectuaron las operaciones, y los factores predictivos seleccionados se relacionaron principalmente para las localizadas en el sitio quirúrgico, con el grado de contaminación, el tipo de intervención y el estado físico preoperatorio del paciente.Introduction: the genesis of the postsurgical infections is multifactor. The are many international studies evidencing the different prediction factors related to the appearance of these complications, which still involve a significant number of patients operated on, thus justifying the interest in the conduction of present paper. Objective: to describe the behavior the some of the prediction factors related to appearance of the postoperative infections in our practice. Methods: a cross-sectional, descriptive and observational study was conducted in admitted and operated on patients with postsurgical infections in the general surgery service of the "Saturnino Lora" Teaching Provincial Hospital over 2008, according to the selected prediction factors. Results: in relation to the contamination, the global rate of postoperative infection and that of the clean wounds are within the universally accepted limits, although are higher in the urgent, dirty and contaminated interventions for that located in the surgical site, as well as in patients with an ASA II and ASA III physical condition according the American Society of Anaesthesiology (ASA) independently of its nutritional status and the surgical time of interventions. Conclusions: the postsurgical infection rates increase as far as the conditions to operate on are unfavourable and the selected prediction factors are related mainly to that located in the surgical site, with de contamination level, the type of intervention and the physical preoperative status of patient.

A descriptive, serial cases study, of 258 patients undergoing surgery in an emergent or elective way who presented postoperative infections was carried out during the triennium 2012-2014 in the General Surgery Service of "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, with the purpose of identifying different factors related to the use of antibiotics in these cases. Among the outstanding results it was obtained that the hospitalization lasted more than 14 days in more than half of the patients whose surgical operations were classified as polluted or dirty, and that in the preoperatory period antibiotics were applied in 77.1% of the series, while in the postoperative phase antibiotics were administered in all those infected. Also, the microbiological studies showed positivity in 86.5% and the most common isolated microorganisms were gramnegative: Klebsiella, pathogen Staphylococcus, Escherichia coli and Acinetobacter. It was concluded that the politics of the rational use of antibiotics with preservatives and therapeutic ends, should be related to the intrahospital circulation of germs, according to the microbiological map and the resistance of these, so as to implement a standardized protocol in this respect.

A descriptive and cross-sectional study of 21 newly-delivered woman undergoing cesarean section, with infection of the surgical place, admitted to Dr. "Nelia Irma Delfín Ripoll" Ginecoobstetric Hospital in Palma Soriano, Santiago de Cuba, was carried out from October, 2014 to the same month in 2015, in order to characterize them according to selected variables. In the series the 20-29 age group, anemia (66.6%) and obesity (42.8%) prevailed as main risk factors, the polluted clean urgent surgery (76.1%), as well as the Staphylococcus aureus and the Escherichia coli as the isolated germs; also, combinations of first line antibiotics were used with favorable results in all the patients. It was concluded that the presence of risk factors and the identification of bacterias as important causal agents, demands maintaining a permanent epidemiologic surveillance to diminish the infection in these patients.

A descriptive and observational serial cases investigation, based on the 258 patients that presented infectious postoperative complications, after undergoing surgical interventions, either in an elective way or as an emergency, was carried out from January, 2012 to December, 2014. Among the main results there was a prevalence of the patients older than 60 (38.4%) and those undergone surgery as an emergency (82.1%); reason why it was observed that the interventions classified as polluted (43.4%) and dirty (23.6%) occupied an important place in the genesis of this complication. It was also more frequent the infection of the superficial operative place (55.5%) regarding the rest of the localizations. It was concluded that factors as the intervention contamination level, the long-lasting surgical time, preoperative physical state in the classes II and III of the American Society of Anesthesiology, operation type and the patient's age, were decisive in the emergence of postsurgical infections.

Patients with cystic fibrosis have a higher risk of developing chronic respiratory infectious diseases. The Nocardia farcinica lung infection is rare in this group of patients, and there are limited publications about this topic. Its diagnosis is complex, due to the clinical and the radiology signs being non-specific. Identification of the agent responsible in the sputum culture is occasionally negative. It is a slow growing organism and for this reason treatment is delayed, which can lead to an increase in complications, hospitable stays, and mortality. A case is reported on a 26 year-old woman with cystic fibrosis and chronic lung colonization by Nocardia farcinica and Aspergillus fumigatus, on long-term treatment with ciprofloxacin, trimethoprim-sulfamethoxazole, and posaconazole, who was admitted to ICU after bilateral lung transplantation. The initial post-operative progress was satisfactory. After discharge, the patient showed a gradual respiratory insufficiency with new chest X-ray showing diffuse infiltrates. Initially, the agent was not seen in the sputum culture. Prompt and aggressive measures were taken, due to the high clinical suspicion of a Nocardia farcinica lung infection. Treatment with a combination of amikacin and meropenem, and later combined with linezolid, led to the disappearance of the lung infiltrates and a clinical improvement. In our case, we confirm the rapid introduction of Nocardia farcinica in the new lungs. The complex identification and the delay in treatment increased the morbimortality. There is a special need for its eradication in patients with lung transplant, due to the strong immunosuppressive treatment., (Copyright © 2013 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.
