Idioma: es.
Resumo: Introducción. El vasoespasmo cerebral como complicación de la Hemorragia subaracnoidea aneurismática, es considerado como una vasoconstricción patológica de las arterias principales de la base del encéfalo; es una condición reversible, que se caracteriza con la reducción del calibre de la luz de las arterias y por lo consiguiente una disminución del flujo sanguíneo al área perfundida por el vaso comprometido. Objetivo. Desarrollar un proceso enfermero basado en la taxonomía Nanda, Noc, Nic a una persona con vasoespasmo cerebral. Metodología. Se realizó la elección de un caso clínico, con la metodología del proceso de atención de enfermería estableciendo un plan de cuidados en el área de recuperación y terapia intermedia del Instituto Nacional de Neurología y Neurocirugía Manuel Velasco Suárez durante el periodo postquirúrgico inmediato. Se detectaron las necesidades básicas alteradas al realizar la valoración neurológica de enfermería. Se procedió a formular los diagnósticos de enfermería reales y de riesgo y con base en estos se planearon las intervenciones de enfermería. Conclusión. El realizar las intervenciones de enfermería de forma sistematizada a partir del proceso enfermero, se establece un método científico, en donde cada intervención se fundamenta y da pauta a la aplicación de un cuidado especializado, dirigido hacia la mejora de la persona desde el punto de vista individual y con ello detectar oportunamente signos y síntomas de alarma así como posibles complicaciones.

Introduction. The cerebral vasospasm as complication of the Haemorrhage subarachnoid aneurismática, is considered to be a pathological vasoconstriction of the main arteries of the base of the brain; it is a reversible condition, which is characterized by the reduction of the caliber of the light of the arteries and for consequent a decrease of the blood flow to the area perfundida for the awkward glass. Target. To develop a process nurse based on the taxonomy Nanda, NOC, NIC to a person with vasospasm cerebral. Methodology. There was realized the election of a clinical case, with the methodology of the process of attention of infirmary establishing a care plan in the field of recovery and intermediate therapy of the National Institute of Neurology and Neurosurgery Manuel Velasco Suárez during the immediate postsurgical period. The basic needs were detected altered on having realized the neurological infirmary evaluation. One proceeded to formulate the real diagnoses of infirmary and of risk and with base in these the infirmary interventions were planned. Conclusion. Realizing the interventions of infirmary of form systematized from the process nurse, establishes a scientific method, where every intervention is based and gives rule to the application of a specializing care, directed to the progress of the person from the individual point of view and with it to detect opportunely signs and symptoms of alarm as well as possible complication.

Idioma: es.
Resumo: Objetivos: Establecer la asociación de vasoespasmo cerebral detectado por Doppler transcraneal y la condición clínica, de acuerdo con la escala de la Federación Mundial de Sociedades de Neurocirugía, y con otros factores de riesgo en pacientes con hemorragia subaracnoidea espontánea. Materiales y métodos: Estudio observacional retrospectivo de casos y controles, con 141 pacientes diagnosticados con hemorragia subaracnoidea espontánea a quienes se les realizó Doppler transcraneal de seguimiento entre el 8 de marzo de 2011 y el 15 de marzo de 2015. Del total de pacientes se escogieron 47 con vasoespasmo detectado por Doppler transcraneal y 2 controles, sin vasoespasmo, por cada caso (94 pacientes). En las historias clínicas y las imágenes de los pacientes se estableció la asociación entre la detección de vasoespasmo por Doppler transcraneal con la condición clínica neurológica en el momento del examen, y otros factores de riesgo. Para el análisis de las variables cualitativas se utilizaron frecuencias absolutas y relativas. Para variables cuantitativas se utilizó la prueba de Shapiro Wilk. Los datos con distribución normal se presentan con medias y desviaciones estándar y aquellos sin distribución normal con medianas y rangos intercuartiles. Se evaluó la homogeneidad entre los dos grupos a través de la prueba de Chi cuadrado y el test de homogeneidad de varianzas (Levene) de acuerdo con el tipo de variable. Se consideró estadísticamente significativa una p ≤ 0,05. Resultados: El análisis bivariado no demostró resultados estadísticamente significativos en la relación entre la condición clínica neurológica y el vasoespasmo, pero sí encontró que pacientes menores de 50 años de edad presentaron más vasoespasmo (OR de 3,55 [95 % IC; 1,52-7,39]), y p: 0,003 que los de mayor edad. Conclusiones: Los pacientes menores de 50 años de edad tienen más riesgo de desarrollar vasoespasmo y no existe asociación entre la condición clínica y los resultados del Doppler transcraneal.

Objectives: Establish the association between cerebral vasospasm, detected by transcranial doppler, with the clinical condition according to the scale of the World Federation of Neurosurgical Societies (WFNS) and other risk factors in patients with spontaneous subarachnoid hemorrhage. Materials and methods: This is an observational retrospective case-control study, including 141 patients with a diagnosis of spontaneous subarachnoid hemorrhage who underwent transcranial doppler monitoring in the radiology department of the University Hospital San Vicente Foundation (HUSVF) from 8 March 2011 to 15 March 2015. Of the total number of patients with subarachnoid hemorrhage, 47 cases with vasospasm, detected by transcranial Doppler, and two controls without vasospasm (94 patients) were consecutively chosen. Subsequently, we review the medical records and images stored in the hospital´s radiology department and established the association between vasospasm detection by trasncranial Doppler with clinical neurological status at the time of the study and other risk factors. For the analysis of the qualitative variables, absolute and relative frequencies were used. Quantitative variables were tested for normal distribution with a Shapiro Wilk test. Data with normal distribution were presented with means and standard deviations and those without normal distribution with medians and interquartile ranges. Homogeneity between the two groups were evaluated by Chi-square test and test for homogeneity of variances, Levene's test, according to the type of variable (qualitative and quantitative respectively). Results were considered statistically significant if p ≤ 0.05. Results: Data from 141 patients (47 cases and 94 controls) were analyzed. The bivariate analysis didn´t show statistically significant results in the relationship between vasospasm and clinical neurological condition but found that patients younger than 50 years had more vasospasm. In the adjusted model for patients with this age, the OR was 3.55 (95 % CI, 1.52-7.39) and p: 0.003 when compared with older patients. Conclusions: This study found that patients under 50 have a higher risk of developing vasospasm compared with older patients and that there is no association between clinical condition and the results of transcranial Doppler.

Idioma: es.
Resumo: Objetivo: El propósito de este estudio es describir las características clínicas, epidemiológicas e imaginológicas de 5 pacientes con diagnóstico de síndrome de vasoconstricción reversible. Métodos: Se hizo una evaluación retrospectiva de las historias clínicas de cinco pacientes con clínica e imágenes compatibles con síndrome de vasoconstricción cerebral reversible en un hospital de alta complejidad de la ciudad de Medellín. Resultados: Los cinco casos correspondían a mujeres con una edad promedio de 50 años. En un caso se identificó como posible agente causal el consumo de bebidas energizantes con alto contenido de taurina. Todos los pacientes se presentaron con hemorragia subaracnoidea en la convexidad y evolucionaron de forma favorable. Conclusión: El síndrome de vasoconstricción cerebral reversible debe ser uno de los diagnósticos diferenciales etiológicos de hemorragia subaracnoidea de la convexidad; se presenta predominantemente en mujeres entre la cuarta y sexta década de la vida y usualmente tiene un curso benigno.

Objective: The purpose of this study is to describe the clinical, epidemiological and imaging characteristics of 5 patients with a diagnosis of reversible vasoconstriction syndrome. Methods: A retrospective evaluation of the clinical records of 5 patients with clinical and imaging diagnosis of reversible cerebral vasoconstriction syndrome was carried out in a high complexity hospital in the city of Medellín. Results: The five cases were women with an average age of 50 years. In one case, the consumption of energy drinks with a high taurine content was identified as a possible causative agent. All cases presented with brain convexity subarachnoid haemorrhage. The clinical outcome was favorable. Conclusion: The reversible cerebral vasoconstriction syndrome should be included in the differential diagnosis of convexity subarachnoid haemorrhage. It occurs predominantly in women between the fourth and sixth decade of life and usually has a benign course.

Título: Terapia endovascular no vasoespasmo cerebral secundário à hemorragia subaracnóidea / Endovascular therapy for the cerebral vasospasm after subarachnoid hemorrhage
Fonte: Arq. bras. neurocir;32(3):186-190, set. 2013.
Idioma: pt.
Resumo: O vasoespasmo cerebral é uma complicação relativamente frequente após episódios de hemorragia subaracnóidea de etiologia aneurismática. É responsável pela mortalidade de aproximadamente 30% dos pacientes e por sequelas neurológicas em 50% dos sobreviventes. Revisão de literatura realizada em julho de 2012. Foram pesquisadas as bases de dados PubMed e BVS e selecionados 37 artigos em português e inglês. A terapia do triplo H, largamente utilizada, diminui complicações isquêmicas, mas pode piorar comorbidades. A nimodipina ainda é a única droga que melhora comprovadamente o prognóstico do paciente. O tratamento endovascular pode ser baseado em angioplastia por balão, que dilata mecanicamente os vasos estreitados, ou em administração intra-arterial de agentes vasodilatadores, como a papaverina. Angioplastia profilática em determinados segmentos arteriais pode reduzir em até 10,4% as complicações isquêmicas. A angioplastia terapêutica tem melhores resultados quando realizada nas duas primeiras horas após a instalação do vasoespasmo sintomático. A papaverina induz melhora angiográfica em até 66% dos pacientes, mas pode estar relacionada à neurotoxicidade. A terapia endovascular parece ter resultados muito positivos para o tratamento do vasoespasmo cerebral. Pela falta de evidências, no entanto, deve ainda ser reservada para pacientes refratários ao tratamento clínico ou com complicações que o impeçam.

Cerebral vasospasm is a relatively frequent complication after aneurysmal subarachnoid hemorrhages. It leads to a 30% mortality rate of patients who survived the hemorrhage and the development of neurologic deficits for 50% of the remaining. This is a literature review performed in July, 2012. Two databases were surveyed: PubMed and VHL. Thirty-seven articles in English and Portuguese were selected. ?Triple-H? therapy, widely employed, reduces ischemic complications, but can deteriorate patient?s comorbidities. Nimodipine still the only certified drug for the treatment of vasospasm. Endovascular treatment can be performed through percutaneous transluminal balloon angioplasty (TBA), which enlarges vessels mechanically, or intra-arterial administration of vasodilating agents, such as papaverine. Prophylactic angioplasty in selected arterial segments can reduce ischemic complications in until 10.4%. Therapeutic angioplasty presents better outcome when performed in the first two hours after the development of symptomatic vasospasm. Papaverine induces angiographic improvement in 66% of patients, but can be related with neurotoxicity. Endovascular therapy seems to present very positive results for the treatment of cerebral vasospasm. However, due to the lack of evidences, it should be reserved for when clinical treatment fails or cannot be performed.

Resumo: Objetivo: presentar dos casos de muerte materna asociados al uso de medicamentos derivados del ergot (ergotismo agudo severo), y realizar una revisión de la literatura de la presentación de eventos adversos en el sistema nervioso central en puérperas expuestas a estos medicamentos. Materiales y métodos: se presentan dos casos de muerte materna posparto, el primero se asoció al uso de bromocriptina para supresión de lactancia y el segundo al uso metilergometrina para controlar hemorragia poscesárea. Las pacientes fueron atendidas en instituciones de tercer nivel de complejidad en la ciudad de Medellín, Colombia. Se realizó revisión de la literatura, registrada en la base de datos Medline vía PubMed. Los términos empleados para la búsqueda fueron: derivados del ergot, bromocriptina, angeítis cerebral posparto, ergotismo, enfermedad vascular cerebral posparto. Se buscaron, sin límite de tiempo, reportes de caso, reportes de series de caso y revisiones de tema. Se buscaron informes o alertas de seguridad de agencias reguladoras tales como: la Federal Drugs Administration (FDA), la European Medicines Agency (EMA) y del Instituto Nacional de Vigilancia de Medicamentos y Alimentos (Invima). Se consultaron artículos en inglés, francés y español. Resultados: se incluyeron 16 publicaciones que cumplieron con los criterios de búsqueda. Se lograron identificar 33 casos. Dos fueron fatales, uno asociado al uso de metilergonovina venosa para el alumbramiento y el otro a ergometrina oral usado como abortivo en la semana 20 de gestación. En las neuroimágenes predominan los hallazgos isquémicos (sugestivos de vasoespasmo cerebral). En tres casos se reportó hemorragia intracerebral, uno de estos fue un caso fatal. Los síntomas más frecuentes de presentación fueron la cefalea intensa, seguida de la convulsión. Solo en nueve casos se logró identificar el antecedente de hipertensión o preeclampsia, y en cuatro migraña. La indicación para el uso de bromocriptina en todos los casos fue suprimir la lactancia. En los tres casos reportados en que se usó metilergonovina fue para realizar alumbramiento. En el sistema de farmacovigilancia colombiano no se encontraron reportes de eventos adversos serios asociados a estos medicamentos. Conclusión: se debe reconocer el ergotismo del sistema nervioso central en el puerperio por el uso de medicamentos tales como la bromocriptina y la metilergonovina, como una entidad potencialmente fatal. Es importante crear una cultura de reporte de eventos adversos serios de estos medicamentos en nuestro país.

Objective: To report two cases of maternal death associated with ergot-derived drugs (acute sever ergotism), and to conduct and review of the literature on central nervous system adverse events during the postpartum period in women exposed to these medications. Materials and methods: Two cases of maternal death during the postpartum period. The first was associated with the use of bromocriptine for breast milk suppression, and the second was associated with the use of methylergometrine for the control of bleeding after Cesarean section. The patients received care at Level III institutions in the city of Medellín, Colombia. A review of the literature was conducted in the Medline database through Pubmed. The terms used for the search were: ergot derivatives, bromocriptine, postpartum cerebralangiitis, ergotism, postpartum cerebral vascular disease. The search was conducted without a time limitation and included, case reports, case series reports, and reviews. The search also included safety reports or alerts from regulatory agencies such as the FDA, the European Medicines Agency (EMA), and Invima. Articles in English, French and Spanish were reviewed. Results: Overall, 16 publications that met the search criteria were included, and 33 cases were identified. Two of the cases were fatal, one associated with the use of intravenous methylergonovine for delivery and the second one was associated with the use of oral ergometrine to induce abortion at 20 weeks of gestation. Neuroimaging studies show, predominantly, ischemic findings (suggestive of cerebral vasospasm). In three cases, intracranial haemorrhage was reported, and one of the three cases was fatal. The most frequent presenting symptoms were intense headache, followed by seizures. It was possible to identify a history of hypertension and/or preeclampsia only in nine cases, and a history of migraine in four. The vast majority of patients were otherwise healthy. In all the cases, the indication for using bromocriptine was breast milk suppression. In the three reported cases in which methylergonovine was used, the indication was to assist delivery. No reports of serious adverse events associated with these drugs were found in the Colombian pharmacovigilance system. Conclusion: Ergotism of the central nervous system due to the use of drugs such as bromocriptine and methylergonovine must be recognised during the postpartum period because it is life-threatening. It is important to create a culture of reporting of serious adverse events associated with these medications in our country.

Idioma: es.
Resumo: La preeclampsia es una afección multisistémica durante el embarazo, con alta tasa de morbilidad y mortalidad en la madre y el hijo. Dentro del espectro de efectos está la alteración del flujo sanguíneo cerebral que en ocasiones se asocia con convulsiones (eclampsia). Se ha intentado encontrar un método diagnóstico para su detección temprana, iniciar la terapia oportuna y reducir los efectos negativos. El doppler transcraneal es un examen no invasivo, de bajo costo y seguro, que puede tener un valor diagnóstico. El objetivo del artículo es una revisión sobre la utilidad del doppler transcraneal y la preeclampsia. Se buscó en la base de datos PubMed con términos MeSh. Diferentes estudios revelan índices de resistencia y pulsatilidad disminuidos en el segundo trimestre del embarazo, los cuales pueden predecir la aparición de preeclampsia...

Pre-eclampsia is a multisystem disorder of pregnancy associated with significant maternal and perinatal morbidity and mortality. Among the spectrum of effects are alterations in cerebral blood flow sometimes associated with convulsions (eclampsia). There is a need for a method for diagnosis and early detection of pre-eclampsia to allow timely intervention and reduce negative effects. Transcranial Doppler is a safe, non- invasive, low-cost method which may have a diagnostic value. The objective of this article is to conduct a review on the utility of transcranial Doppler and pre-eclampsia. The PubMed data base was reviewed using MeSh terms. Different studies reveal reduced resistance and pulsatility indices in the second trimester of pregnancy, which may predict the development of pre-eclampsia...

Título: Relevancia de la hiperglucemia para la evolución y el desenlace de la hemorragia subaracnoidea aneurismática: evidencias y mecanismos / Relevance of hyperglycemia on the course and outcome of aneurysmal subarachnoid hemorrhage: evidence and mechanisms
Fonte: Invest. clín;55(3):278-288, sep. 2014. ilus.
Idioma: es.
Resumo: La hemorragia subaracnoidea aneurismática (HSAa) puede tener un desenlace mortal en unas pocas semanas debido por las complicaciones que presenta, como el vasoespasmo y el edema cerebrales junto con la hiperglucemia. La hiperglucemia podría estar relacionada con el desarrollo del vasoespasmo y el edema cerebrales. Es posible que el control de la glucemia juegue un papel central en la evolución y el desenlace de la HSAa. Se han descrito los mecanismos por los cuales puede darse esta relación, que incluyen el equilibrio de iones, la liberación de aminoácidos excitadores, la estimulación de moléculas vasoconstrictoras y la disminución en la síntesis de vasorrelajantes. Sin embargo, existen estudios que no apoyan la hipótesis sobre la participación de la hiperglucemia en esta enfermedad. En conjunto, estas evidencias sugieren que el control de los niveles de glucosa podría modificar el desenlace de los grupos de pacientes con HSAa dependiendo de las complicaciones que presenten.

Aneurysmal subarachnoid hemorrhage (aSAH) may have a fatal outcome after a few weeks from ictus, due to its complications, like cerebral vasospasm and edema along with hyperglycemia. Hyperglycemia may be involved in the development of brain vasospasm and edema. It is possible that hyperglycemia plays a central role in the outcome of aSAH. Several mechanisms may explain this relationship; they include ion balance, excitatory amino acid release, stimulation of vasoconstrictor molecules and reduced synthesis of vasorelaxants. However, some studies do not support this hypothesis regarding the role of hyperglycemia in aSAH. Taken together, the evidence suggests that the control of glucose levels may influence the aSAH outcome depending on the complications that may develop.

Título: Expression of Sphingosine-1-phosphate (S1P) on the cerebral vasospasm after subarachnoid hemorrhage in rabbits
Fonte: Acta cir. bras;30(10):654-659graf.
Idioma: en.
Resumo: PURPOSE:To demonstrate the relationship between of sphingosine-1-phosphate (S1P) expression and subarachnoid hemorrhage (SAH).METHODS:The basilar arteries from a "double-hemorrhage" rabbit model of SAH were used to investigate the relation between S1P expression and SAH. Various symptoms, including blood clots, basilar artery cross-sectional area, and S1P phosphatase expression were measured at day 3, 5, 7, 9.RESULTS: The expression of S1P was enhanced in the cerebral vasospasm after subarachnoid hemorrhage in the rabbits. And S1P expression was consistent with the basilar artery cross-sectional area changes at day 3, 5, 7, 9.CONCLUSION: Sphingosine-1-phosphate expression in the cerebral arterial may be a new indicator in the development of cerebral vasospasm after subarachnoid hemorrhage and provide a new therapeutic method for SAH.

Idioma: es.
Resumo: Background: Early mobilization in intensive care units (ICU) provides respiratory, neurological and cardiovascular benefits in hospitalized patients. However, the orthostatic effects of changing from a supine to a sitting position may interfere with cerebral hemodynamics of patients with aneurysmal subarachnoid hemorrhage (aSAH). Aim: To describe the changes in mean cerebral blood flow velocity (MCBFV) in supine and sitting position, in adult patients with aSAH, with asymptomatic vasospasm (AVS) or without vasospasm (VS) at a neurosurgical ICU. Material and Methods: Descriptive case series study in 21 patients with aSAH, both with and without VS. They were positioned in a supine 30° position and then seated at the edge of bed for six minutes. MCBFV was measured by transcranial Doppler (TCD), and hemodynamic variables in both positions were registered. After this basal assessment and for 21 days after the episode of SAH, patients were seated once a day and signs of VS were recorded. Results: No significant changes in MCBFV or hemodynamic variables were detected during position changes, except for an increase in heart rate in the sitting position. No patient with AVS at the onset, had symptomatic VS during the 21 days of follow up when patients were seated. Among patients with a normal MCBFV at baseline, five patients (24%) had VS at a mean of three days after the first time that they were seated on the edge of bed. Conclusions: Sitting patients at the edge of the bed is a safe mobilization alternative for patients who suffered aSAH who did not have VS or had AVS.
