Clinical significance of sirtuin 1 level in sepsis: correlation with disease risk, severity, and mortality risk

This study aimed to investigate the value of sirtuin 1 (SIRT1) in differentiating sepsis patients from healthy controls (HCs), and its correlation with inflammation, disease severity, as well as prognosis in sepsis patients. Serum samples were collected from 180 sepsis patients and 180 age- and gender-matched HCs. The SIRT1 level in the serum samples was detected by enzyme-linked immunoassay. The clinical data of the sepsis patients were documented, and their disease severity scores and 28-day mortality rate were assessed. SIRT1 was decreased in sepsis patients compared with HCs, and the receiver operating characteristic curve (ROC) showed that SIRT1 distinguished sepsis patients from HCs (area under the curve (AUC): 0.901; 95% confidence interval (CI): 0.868-0.934). In sepsis patients, SIRT1 negatively correlated with serum creatinine (Scr), white blood cells (WBC), C-reactive protein (CRP), acute physiology, and chronic health evaluation II (APACHE II) score, and sequential organ failure assessment (SOFA) score, while it positively correlated with albumin. No correlation of SIRT1 with primary infection site or primary organism was observed. Furthermore, SIRT1 was reduced in 28-day non-survivors compared with 28-day survivors, and subsequent ROC showed that SIRT1 predicted 28-day mortality of sepsis patients (AUC: 0.725; 95% CI: 0.651-0.800), and its prognostic value was not inferior to Scr, albumin, WBC, and CRP, but was less than SOFA score and APACHE II score. In conclusion, measurement of serum SIRT1 might assist with the optimization of disease assessment, management strategies, and survival surveillance in sepsis patients.

Razão neutrófilo-linfócito no diagnóstico precoce de sepse em unidade de terapia intensiva: um estudo de caso-controle / Neutrophil-lymphocyte ratio in the early diagnosis of sepsis in an intensive care unit: a case-control study

RESUMO Objetivo: Avaliar a razão neutrófilo-linfócito na predição de sepse e mortalidade em pacientes admitidos em uma unidade de terapia intensiva. Métodos: Estudo de caso-controle de pacientes adultos admitidos em terapia intensiva. Foram incluídos como casos pacientes que tiveram sepse como razão de admissão e possuíam exame laboratorial de hemograma prévio. As análises estatísticas realizadas foram curva ROC, regressão logística binária, Mann Whitney e qui-quadrado de Pearson. Foi considerado significativo valor de p < 0,05. Resultados: Os valores de curva ROC foram 0,62 para razão neutrófilo-linfócito, 0,98 para neutrófilos bastonados e 0,51 para leucócitos totais. A presença de razão neutrófilo-linfócito superior a 5,0, o número de leucócitos acima de 12.000mm3/mL e número de neutrófilos bastonados acima 10% foram fatores de risco para sepse, entretanto somente os escores SAPS 3 e SOFA estavam relacionados a mortalidade dos pacientes. Conclusão: A razão neutrófilo-linfócito e os neutrófilos bastonados em combinação com outros parâmetros podem ser marcadores na detecção precoce de sepse em terapia intensiva.

ABSTRACT Objective: To evaluate the neutrophil-lymphocyte ratio as a predictor of sepsis and mortality in patients admitted to an intensive care unit. Methods: Case-control study of adult patients admitted to an intensive care unit. Patients who had sepsis as the reason for admission and who had a previous complete blood count examination were included as case patients. The following statistical analyses were performed: ROC curves, binary logistic regression, and Mann-Whitney and Pearson's chi-square tests. p < 0.05 was considered significant. Results: The ROC curve values were 0.62 for neutrophil-lymphocyte ratio, 0.98 for band neutrophils and 0.51 for total leukocytes. The presence of a neutrophil-lymphocyte ratio greater than 5.0, leukocyte count above 12,000mm3/mL and band neutrophil percentage above 10% were risk factors for sepsis; however, only the SAPS 3 and SOFA score were related to patient mortality. Conclusion: The neutrophil-lymphocyte ratio and band neutrophils in combination with other parameters may be markers for the early detection of sepsis in intensive care units.

Codificação da sepse pulmonar e o perfil de mortalidade no Rio de Janeiro, RJ / Coding pulmonary sepsis and mortality statistics in Rio de Janeiro, RJ

RESUMO: Objetivo: Descrever os óbitos com menção de sepse pulmonar, medir a associação entre sepse pulmonar e pneumonia, assim como avaliar o impacto da regra de codificação no perfil de mortalidade, com a inclusão simulada do diagnóstico de pneumonia, nas declarações de óbito (DO) com menção de sepse pulmonar, no Rio de Janeiro, em 2011. Métodos: Foram identificados os óbitos com menção de sepse pulmonar independentemente da causa básica. Aos médicos atestantes, aplicou-se questionário medindo a associação entre sepse pulmonar e pneumonia. O registro de pneumonia nos prontuários dos óbitos com menção de sepse pulmonar e sem menção de pneumonia na DO foi investigado. Foi descrito o perfil de mortalidade após a inclusão simulada do código de pneumonia nas declarações com sepse pulmonar. Resultados: Sepse pulmonar correspondeu a 30,9% das menções de sepse e a menção de pneumonia estava ausente em 51,3% dessas declarações. Pneumonia constava em 82,8% da amostra de prontuários investigados. Dos médicos entrevistados, 93,3% relataram pneumonia como a mais frequente causa de sepse pulmonar. A simulação revelou que a inclusão da pneumonia alterou a causa básica de 7,8% dos óbitos com menção de sepse e 2,4% de todos os óbitos, independentemente da causa original. Conclusão: Sepse pulmonar está associada à pneumonia e a simples inclusão do código de pneumonia nas declarações de óbito com menção de sepse pulmonar impactaria o perfil de mortalidade, apontando necessidade de aprimoramento das regras de codificação na Classificação Internacional de Doenças (CID-10).

ABSTRACT: Objectives: This study aimed to describe "pulmonary sepsis" reported as a cause of death, measure its association to pneumonia, and the significance of the coding rules in mortality statistics, including the diagnosis of pneumonia on death certificates (DC) with the mention of pulmonary sepsis in Rio de Janeiro, Brazil, in 2011. Methods: DC with mention of pulmonary sepsis was identified, regardless of the underlying cause of death. Medical records related to the certificates with reference to "pulmonary sepsis" were reviewed and physicians were interviewed to measure the association between pulmonary sepsis and pneumonia. A simulation was performed in the mortality data by inserting the International Classification of Diseases (ICD-10) code for pneumonia in the certificates with pulmonary sepsis. Results: "Pulmonary sepsis" constituted 30.9% of reported sepsis and pneumonia was not reported in 51.3% of these DC. Pneumonia was registered in 82.8% of the sample of the medical records. Among physicians interviewed, 93.3% declared pneumonia as the most common cause of "pulmonary sepsis." The simulation of the coding process resulted in a different underlying cause of death for 7.8% of the deaths with sepsis reported and 2.4% of all deaths, regardless the original cause. Conclusion: The conclusion is that "pulmonary sepsis" is frequently associated to pneumonia and that the addition of the ICD-10 code for pneumonia in DC could affect the mortality statistics, highlighting the need to improve mortality coding rules.

Sepsis neonatal grave en una unidad de cuidados intensivos / Severe neonatal sepsis in an intensive care unit

INTRODUCCIÓN: la sepsis neonatal grave se produce en 0,5 a 8,0 de cada 1 000 nacidos vivos, y es la causa más común de muerte neonatal. OBJETIVO: caracterizar la sepsis neonatal grave en los pacientes ingresados en el servicio de Neonatología del Hospital Universitario Ginecoobstétrico "Mariana Grajales", de Santa Clara, durante los años 2011-2012. MÉTODOS: se realizó un estudio observacional, descriptivo, de tipo transversal, con elementos de enfoque cualitativo y cuantitativo. El universo de estudio quedó conformado por el total de recién nacidos con sepsis neonatal grave (105 neonatos), lo que coincidió con la muestra. Las variables perinatales seleccionadas fueron: total de nacidos vivos, ingresos en terapia neonatal (con sepsis y con sepsis graves), edad gestacional, clasificación de la sepsis, microorganismos aislados, estudios microbiológicos y tasa por 1 000 nacidos vivos por infección. RESULTADOS: de los 145 neonatos con diagnóstico de sepsis, 105 de ellos evolucionaron con sepsis grave (72,4 %). Se comprobó que 70 pacientes del total nacieron pretérminos, que representó el 66,6 %; y 74 niños presentaron sepsis generalizada adquirida confirmada. Fue más frecuente el aislamiento del Staphylococcus coagulasa negativo. CONCLUSIONES: más de la mitad de los neonatos con sepsis se comportaron como una sepsis grave. La prematuridad se relacionó estrechamente con esta entidad en la etapa neonatal. La sepsis generalizada adquirida fue la más frecuente. Más de la mitad de los hemocultivos fueron positivos, y los microorganismos más frecuentes fueron el Staphylococcus coagulasa negativo y la Candida.

INTRODUCTION: severe neonatal sepsis occurs in 0.5 to 8 per 1 000 livebirths and is the common cause of neonatal death. OBJECTIVE: to characterize the severe neonatal sepsis in patients admitted to the neonatology service of "Mariana Grajales" university gynecological and obstetric hospital located in Santa Clara during 2011 and 2012. METHODS: observational, descriptive and cross-sectional study was conducted, using quantitative and qualitative-focused elements. The universe of study was the total number of newborns with severe neonatal sepsis (105 neonates), which agreed with the sample. The selected perinatal variables included total number of livebirths, admissions to neonatal therapy service (with sepsis and severe sepsis), gestational age, classification of sepsis, isolated microorganisms, microbiological studies and infection rate per 1 000 livebirths. RESULTS: of 145 neonates with sepsis diagnosis, 105 progressed into severe sepsis (72.4 %). It was confirmed that 70 patients were preterm born, accounting for 66.6 % and 74 children presented with confirmed acquired generalized sepsis. The most isolated agent was negative Staphylococcus coagulase. CONCLUSIONS: half of neonates with sepsis behaved as if they had severe sepsis. Prematurity was closely related to this entity at the neonatal phase. Acquired generalized sepsis was the most common. More than 50 % of the hemocultures were positive and the most frequent ones were negative Staphylococcus coagulase and Candida.

Late recognition and illness severity are determinants of early death in severe septic patients

OBJECTIVE: To identify the independent variables associated with death within 4 days after the first sepsis-induced organ dysfunction. METHODS: In this prospective observational study, severe sepsis and septic shock patients were classified into 3 groups: Group 1, survivors; Group 2, late non-survivors; and Group 3, early non-survivors. Early death was defined as death occurring within 4 days after the first sepsis-induced organ dysfunction. Demographic, clinical and laboratory data were collected and submitted to univariate and multinomial analyses. RESULTS: The study included 414 patients: 218 (52.7%) in Group 1, 165 (39.8%) in Group 2, and 31 (7.5%) in Group 3. A multinomial logistic regression analysis showed that age, Acute Physiology and Chronic Health Evaluation II score, Sepsis-related Organ Failure Assessment score after the first 24 hours, nosocomial infection, hepatic dysfunction, and the time elapsed between the onset of organ dysfunction and the sepsis diagnosis were associated with early mortality. In contrast, Black race and a source of infection other than the urinary tract were associated with late death. Among the non-survivors, early death was associated with Acute Physiology and Chronic Health Evaluation II score, chronic renal failure, hepatic dysfunction Sepsis-related Organ Failure Assessment score after 24 hours, and the duration of organ dysfunction. CONCLUSION: Factors related to patients' intrinsic characteristics and disease severity as well as the promptness of sepsis recognition are associated with early death among severe septic patients. .

Impacto clínico do diagnóstico de sepse à admissão em UTI de um hospital privado em Salvador, Bahia / Clinical impact of sepsis at admission to the ICU of a private hospital in Salvador, Brazil

OBJETIVO: Descrever as características clínicas, os dados laboratoriais e o desfecho clínico de pacientes sépticos e não sépticos admitidos em UTI de um hospital privado na cidade de Salvador, Bahia, e identificar variáveis clínicas relacionadas ao pior prognóstico dos pacientes sépticos. MÉTODOS: Foi realizado um estudo longitudinal que incluiu todos os pacientes admitidos na UTI geral do Hospital Português, Salvador (BA), entre junho de 2008 e março de 2009. Na admissão na UTI, dois grupos de pacientes foram identificados: sépticos e não sépticos. Foram coletados dados epidemiológicos, clínicos e laboratoriais, e o escore Acute Physiology and Chronic Health Evaluation II (APACHE II) foi calculado. RESULTADOS: Dos 144 pacientes do estudo, 29 (20,1 por cento) eram sépticos. Entre os pacientes sépticos, 55,2 por cento eram do sexo masculino, a média de idade foi de 73,1 ± 14,6 anos, e a média do escore do APACHE II foi de 23,8 ± 9,1. No grupo não séptico, 36,3 por cento eram do sexo masculino, a média de idade foi de 68,7 ± 17,7 anos, e a média do escore do APACHE II foi de 18,4 ± 9,5. Houve associações estatisticamente significantes entre o diagnóstico de sepse e as seguintes variáveis: escore do APACHE II, mortalidade na UTI, mortalidade hospitalar, FC, pressão arterial média, valor de hematócrito, contagem de leucócitos e uso de antibioticoterapia. O uso de medidas de suporte e valores reduzidos de hematócrito se relacionaram com um pior prognóstico entre os pacientes sépticos. CONCLUSÕES: Os pacientes diagnosticados com sepse apresentaram piores desfechos clínicos, provavelmente por causa de sua maior gravidade. O nível de hematócrito foi a única variável capaz de predizer o risco de morte entre pacientes sépticos.

OBJECTIVE: To describe the clinical characteristics, laboratory data, and clinical outcomes of patients with and without sepsis admitted to the ICU of a private hospital in the city of Salvador, Brazil, and to identify clinical variables related to a worse prognosis in those with sepsis. METHODS: This was a longitudinal study including all patients admitted to the general ICU of the Hospital Português, in the city of Salvador, Brazil, between June of 2008 and March of 2009. At ICU admission, two groups of patients were identified: with sepsis and without sepsis. Epidemiological, clinical and laboratory data were collected, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score was calculated. RESULTS: Of the 144 patients in the study, 29 (20.1 percent) had sepsis. Among the patients with sepsis, males accounted for 55.2 percent, the mean age was 73.1 ± 14.6 years, and the mean APACHE II score was 23.8 ± 9.1, compared with 36.3 percent, 68.7 ± 17.7 years, and 18.4 ± 9.5, respectively, among those without sepsis. There were significant associations between a diagnosis of sepsis and the following variables: APACHE II score; in-hospital mortality; ICU mortality; HR; mean arterial pressure; hematocrit level; white blood cell count; and antibiotic use. The use of life support measures and lower hematocrit levels were associated with a worse prognosis in the patients with sepsis. CONCLUSIONS: The patients diagnosed with sepsis presented worse clinical outcomes, probably due to their greater severity. Hematocrit level was the only variable that was a predictor of mortality risk in the patients with sepsis.

Comparación de los modelos pronósticos APACHE II y Score Salvador en sepsis abdominal / Comparison of APACHE II and Score Salvador models of prediction in abdominal sepsis

La evolución y pronóstico de la sepsis abdominal están determinados por la rapidez con que se efectúa el diagnóstico, intervención apropiada y la eficacia y oportunidad del tratamiento antibiótico. Los estudios clínicos han identificado algunos factores de mal pronóstico, entre los cuales se encuentran el puntaje APACHE II elevado. Nosotros realizamos un estudio retrospectivo en la Unidad de Cuidados Intensivos del Hospital del Salvador, comparando el Score Apache II con un Score local, denominado Score del Salvador, en los pacientes con diagnóstico de sepsis abdominal. Resultados: Hubo 2.158 ingresos en la UCI del Hospital del Salvador, correspondiendo a 7,6% (n =164) de los casos a sepsis abdominal. Las principales causas de infección abdominal fueron perforación intestinal, colangitis, obstrucción intestinal y pancreatitis aguda. La comparación de las curvas receptor-operador del Score del Salvador y el índice pronóstico Apache II, evidencia que no existen diferencias significativas en el área bajo la curva de ambos índices pronósticos en pacientes con sepsis abdominal. Conclusión: Ambos índices pronósticos fueron comparables plenamente. Dado el escaso número de pacientes enrolados y la gravedad de ellos el valor predictivo es limitado lo que sugiere necesario aumentar el tamaño de la muestra y diversificar la gravedad.

The evolution and presage of the abdominal sepsis are determined by the speed with which it is made the diagnosis, appropriate intervention and the effectiveness and opportunity of the antibiotic treatment. The clinical studies have identified some factors of bad presage, among which are the high score APACHE II. We carry out a retrospective study in the Intensive Care Unit of the Salvador's Hospital, comparing the Apache Score II with a local score, denominated Score of the Salvador to the patients with the diagnose of abdominal sepsis. Results: There were 2.158 revenues in the ICU of the Salvador's Hospital, corresponding 7,6% (n =164) of the cases to abdominal sepsis. The main causes of abdominal infection were intestinal perforation, colangitis, intestinal obstruction, and sharp pancreatitis. The comparison of the curves receiver-operator of the Salvador's Score and the index Apache II, it evidences that significant differences don't exist in the area under the curve of both index in patient with abdominal sepsis. Conclusion: Both scores were comparable fully. Given the scarce number of signed up patients and the graveness of them, the predictive value is limited what suggests necessary to increase the size of the sample and to diversify the graveness.

Epidemiology of severe sepsis in the emergency department and difficulties in the initial assistance

BACKGROUND: The aim of this study was to determine the occurrence rate, demographics, clinical characteristics, and outcomes of patients with severe sepsis admitted to the emergency department. METHODS: A prospective study evaluating all patients admitted to the emergency department unit in a public hospital of tertiary complexity in a six-month period was conducted. During this period, the emergency team was trained to diagnose sepsis. Patients who met the diagnostic criteria for severe sepsis were followed until their discharge from the hospital. RESULTS: A total of 5,332 patients were admitted to the emergency department, and 342 met the criteria for severe sepsis/septic shock. The median (interquartile range) age of patients was 74 (65-84) years, and 52.1 percent were male. The median APACHE II and SOFA scores at diagnosis were 19 (15-25) and 5 (3-7), respectively. The median number of dysfunctional organ systems per patient was 2 (1-3). The median hospital length of stay was 10 (4.7-17) days, and the hospital mortality rate was 64 percent. Only 31 percent of the patients were diagnosed by the emergency department team as septic. About 33.5 percent of the 342 severe sepsis patients admitted to the emergency department were referred to an ICU, with a median time delay of 24 (12-48) hours. Training improved diagnosis and decreased the time delay for septic patients in arriving at the ICU. CONCLUSIONS: The occurrence rate of severe sepsis in the emergency department was 6.4 percent, and the rate of sepsis diagnosed by the emergency department team as well as the number of patients transferred to the ICU was very low. Educational campaigns are important to improve diagnosis and, hence, treatment of severe sepsis.

The impact of duration of organ dysfunction on the outcome of patients with severe sepsis and septic shock

OBJECTIVES: This study aimed to assess the impact of the duration of organ dysfunction on the outcome of patients with severe sepsis or septic shock. METHODS: Clinical data were collected from hospital charts of patients with severe sepsis and septic shock admitted to a mixed intensive care unit from November 2003 to February 2004. The duration of organ dysfunction prior to diagnosis was correlated with mortality. Results were considered significant if p<0.05. RESULTS: Fifty-six patients were enrolled. Mean age was 55.6 ± 20.7 years, mean APACHE II score was 20.6 ± 6.9, and mean SOFA score was 7.9 ± 3.7. Thirty-six patients (64.3 percent) had septic shock. The mean duration of organ dysfunction was 1.9 ± 1.9 days. Within the univariate analysis, the variables correlated with hospital mortality were: age (p=0.015), APACHE II (p=0.008), onset outside the intensive care unit (p=0.05), blood glucose control (p=0.05) and duration of organ dysfunction (p=0.0004). In the multivariate analysis, only a duration of organ dysfunction persisting longer than 48 hours correlated with mortality (p=0.004, OR: 8.73 (2.37-32.14)), whereas the APACHE II score remained only a slightly significant factor (p=0.049, OR: 1.11 (1.00-1.23)). Patients who received therapeutic interventions within the first 48 hours after the onset of organ dysfunction exhibited lower mortality (32.1 percent vs. 82.1 percent, p=0.0001). CONCLUSIONS: These findings suggest that the diagnosis of organ dysfunction is not being made in a timely manner. The time elapsed between the onset of organ dysfunction and initiation of therapeutic intervention can be quite long, and this represents an important determinant of survival in cases of severe sepsis and septic shock.

Fatores de risco associados à mortalidade em pacientes com sepse em unidade de terapia intensiva de hospital privado de Pernambuco / Risk factors associated to mortality on septic patients in an intensive care unit of a general private hospital from Pernambuco

JUSTIFICATIVA E OBJETIVOS: Verificar a associação entre as características clínicas, epidemiológicas e laboratoriais com a mortalidade de pacientes com sepse, internados em UTI de hospital privado do estado de Pernambuco (Nordeste do Brasil), a fim de melhorar o atendimento a essa população, através da identificação precoce dos pacientes com risco de desenvolver falência de órgãos. MÉTODO: Estudo de caso-controle aninhado a uma coorte prospectiva e observacional que incluiu os pacientes adultos admitidos na UTI com sepse ou que a desenvolveram durante a internação. Foram colhidos os dados epidemiológicos, avaliados os escores clínicos e exames laboratoriais como: D-dímero, antitrombina III, INR, contagem de plaquetas, sódio, albumina, lactato e creatinina, sendo analisada sua associação com a mortalidade. Os pacientes foram acompanhados até a alta da UTI ou óbito. RESULTADOS: Foram incluídos no estudo 199 pacientes. Após regressão logística, apenas o tempo de internação na UTI maior que 72h, a presença de doença crônica associada, o número de órgãos acometidos superior a três e o lactato maior que 4 mmol/L estiveram associados com a mortalidade. Com relação à associação com o intervalo de tempo para o óbito, apenas o escore SOFA foi significativo, pois um terço dos pacientes com pontuação superior a 12 foram a óbito em menos de 72h. CONCLUSÕES: Os pacientes admitidos com sepse na UTI provenientes da comunidade (tempo de internação hospitalar < 72 horas) apresentaram melhor prognóstico, os pacientes com maior número de órgãos com disfunção apresentaram risco de óbito mais elevado. Laboratorialmente apenas o lactato elevado esteve associado com a mortalidade.

BACKGROUND AND OBJECTIVES: Verify the association between clinical, epidemiological and laboratorial characteristics with mortality of septic patient in an Intensive Care Unit (ICU) from Pernambuco, northeast of Brazil, to improve the attention for patients with sepse which are in risk of developing organ dysfunction. METHODS: Case-control study, without intervention, that included adults' patients admitted in ICU with sepsis or that developed it during ICU stay. RESULTS: It was included 199 patients. After logistic regression, the length of hospital stay more than 72 hours before admission in ICU, evidence of associated co-morbidities, more than three organ failures, and lactate more than 4 mmol/L were associated with mortality. The SOFA score with more than 12 points was associated with precocity mortality (< 72hours). CONCLUSIONS: The septic patients admitted ICU with less than 72h of hospital stay have a better prognosis, and those with a great number of organ failure, and co-morbidities have a superior mortality rate. Between laboratory results, only the high concentration of lactate is associated with mortality.

Modelo preditivo de mortalidade em idosos com choque séptico / Simple model of morbility of elderly with septic shock

Objetivo:Elaborar um modelo prognóstico simples de mortalidade em idoso com choque séptico, internados em unidade de terapia intensiva (UTI).Métodos: Coorte prospectiva de 67 pacientes idosos consecutivos (idade maior ou igual 65 anos), internados em uma UTI clínica, no período de 32 meses, tendo monitoração da artéria pulmonar devido ao choque séptico. Para o modelo de regressão logística empregou-se como variável dependente o óbito e como variáveis independentes apenas aquelas estatisticamente significativas na análise univariada: o APACHE II, a presença de doenças cardiovasculares prévias (hipertensão arterial) sistêmica, diabetes mellitus...

Consideraciones sobre la sepsis intrahospitalaria en un servicio de geriatría / Considerations on intrahospital sepsis in a geriatric service

Se realizó un estudio longitudinal y descriptivo sobre la sepsis intrahospitalaria en el servicio de geriatría del hospital León Cuervo Rubio, Pinar del Río, Cuba, durante los años 2002 y 2003. El objetivo fue describir su comportamiento, después de exigir, en el último año, el cumplimiento de un grupo de medidas para disminuirla. Del total de 497 pacientes ingresados en el servicio durante el año 2002 se estudiaron 34 y de un total de 571 pacientes hospitalizados durante el 2003, se estudiaron 17; todos con el diagnostico de sepsis intrahospitalaria. Se analizaron los siguientes datos tomados de las historias clínicas y del libro de control de sepsis intrahospitalaria: edad, estadía, frecuencia de cateterización venosa y urinaria, presencia de sepsis respiratoria y costo por estadía. Los resultados se expresaron en porcentajes. Se encontró que el grupo de pacientes con edades entre 76 y 80 años fue el que aportó mayor cantidad de pacientes en el 2002 y en el 2003. El mayor número de pacientes en el 2002 tuvo una estadía entre 16 y 21 días mientras que en el 2003, el mayor número de pacientes tuvo una estadía entre 6 y 10 días. El tipo de cateterismo más frecuente en ambos grupos fue la sonda vesical. La flebitis y la sepsis urinaria predominaron en los 2 años estudiados. La implementación en la práctica de las medidas establecidas propició una mejoría en la calidad de la atención del paciente geriátrico y un ahorro por estadía de $ 689,01 en 1 año(AU)

He/she was carried out a longitudinal and descriptive study on the sepsis intrahospitalaria in the service of geriatrics of the hospital León Blond Crow, Pinegrove of the River, Cuba, during the years 2002 and 2003. The objective was to describe its behavior, after demanding, in the last year, the execution of a group of measures to diminish her. Of the total of 497 patients entered in the service during the year 2002 34 they were studied and of a total of 571 patients hospitalized during the 2003, 17 were studied; all with the I diagnose of sepsis intrahospitalaria. The following taken data of the clinical histories were analyzed and of the book of control of sepsis intrahospitalaria: age, demurrage, frequency of veined cateterización and urinaria, presence of breathing sepsis and cost for demurrage. The results were expressed in percentages. It was found that the group of patient with ages between 76 and 80 years the one that contributed bigger quantity of patient in the 2002 was and in the 2003. The biggest number of patient in the 2002 had a demurrage between 16 and 21 days while in the 2003, the biggest number of patients had a demurrage between 6 and 10 days. The type of more frequent cateterismo in both groups was the probe vesical. The phlebitis and the sepsis urinaria prevailed in the 2 studied years. The implementation in the practice of the established measures propitiated an improvement in the quality of the attention of the patient geriatric and a saving for demurrage of $689,01 in 1 year(AU)

SRIS, sepsis y SDOM: una visión quirúrgica / Systemic inflammatory response syndrome, sepsis and dysfunction multiorganic syndrome: asurgical point of view

En la práctica quirúrgica diaria es cada vez más frecuente encontrar pacientes en estado crítico, con cuadros de sepsis. CDC (Centers for Disease Control and Preventions) estima que la incidencia de sepsis ha ido en aumento: de 73,6 por 100.000 habitantes en 1979 a 175,9 por 100.000 habitantes en 1989. Este aumento puede ser debido al aumento de uso de fármacos citotóxicos e inmunodepresores, el aumento de la edad de la población, el aumento de infecciones por gérmenes resistentes a antibióticos y el aumento en el uso de dispositivos invasivos como catéteres intravasculares. En este artículo se revisan las definiciones más importantes acerca de éste tema, dos de los principales escores de gravedad y disfunción multiorgánica (APACHE II y SOFA) y las medidas terapéuticas que han demostrado mejorar el pronóstico en éste grupo de pacientes.

Mortalidad Perinatal / Perinatal mortality

Se analizaron 90 historias de Muertes Perinatales (MP) en el Hospital Dr. Patrocinio Peñuela Ruíz de San Cristobal, Estado Táchira, en los años 1991 a 1995. La MP se distribuyó en 33 Mortinatos, 51 Muertes Perinatales Precoces (MPP) y 6 Muertes Perinatales Tardías (MPT). Las principales causas de MP en general fueron: 1-Prematuridad; 2-Anoxia; 3-Causas desconocidad; 4-Malformaciones congénitas. Por lo que sugerimos control prenatal precoz, buena asistencia pre-natal, principalmente de los embarazos de alto riesgo, buen registro de todas las causas directas y predisponentes de MP, y por último autopsias que evidencian la verdadera causa. Esto llevar a disminuir las tasas de MP y a evitar el daño irreversible de los neonatos con hipoxia y prematuridad
