Intervenciones de enfermería en la persona con vasoespasmo cerebral secundario a hemorragia subaracnoidea aneurismática / Nursing interventions in the person with a secondary cerebral vasospasm aneurysmal subarachnoid haemorrhage

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.

Unresolved issues in the management of aneurysmal subarachnoid hemorrhage.

A cerebral aneurysm is an outpouching of a weakened arterial wall, usually at a bifurcation of one of the larger vessels of the Circle of Willis. When the outpouching ruptures, arterial pressure forces blood into the subarachnoid space. The annual incidence of aneurysmal subarachnoid hemorrhage is 8 to 10 per 100 000 in the United States. The outcome varies for this patient population. New management strategies have emerged; some practices are evidence based, whereas others are based on anecdotal experiences. This variation has resulted in a number of unresolved issues in caring for patients with an aneurysmal subarachnoid hemorrhage. This article discusses some of these unresolved issues, including the use of medications such as nimodipine, antifibrinolytics, statins, and magnesium; coiling or clipping for aneurysm securement; and the prevention and treatment of potential complications. Critical care nurses must conduct detailed assessments and provide complex care to optimize patient outcomes.

Nonspecific behaviors as early indications of cerebral vasospasm.

This study investigated nonspecific behaviors as early indications of vasospasm following subarachnoid hemorrhage. Although symptoms of vasospasm (e.g., lowered level of consciousness, focal deficits such as hemiplegia or aphasia), are well recognized, the significance of early appearance of nonspecific symptoms such as restlessness, unusual behaviors, and impulsive behavior has not been investigated in detail. The study design included descriptive quantitative elements and a small qualitative component. Nonspecific behaviors were recorded, and the prevalence of those behaviors in individuals developing vasospasm was noted. Of 60 participants, 31 developed vasospasm; 24 of the 31 initially presented with nonspecific behaviors (p < .0001). Early detection of cerebral vasospasm allows prompt intervention and treatment, with the goal of preventing further ischemia or infarction.

Vasospasm after aneurysmal subarachnoid hemorrhage.

Despite every effort, 13% of patients with SAH still die or are permanently disabled as a consequence of vasospasm. Optimal outcome after aneurysmal SAH depends on careful assessment and management of patients throughout the course of hospitalization. Critical care nurses play a crucial role in this process. Efforts continue to understand the cascade of events that lead to cerebral vasospasm and to develop more effective treatments. Many therapies, both traditional and new, are being investigated to reduce the incidence of symptomatic vasospasm and improve the lives of patients who experience this devastating condition.

Analysis of nursing assessments in a cohort patients with ruptured cerebral aneurysms.

Patients admitted with subarachnoid hemorrhage are monitored for symptoms of vasospasm. A prospective study was designed to compare two monitoring instruments: a standard neurological tool (SNR) and the National Institutes of Health Stroke Scale (NIHSS). The two assessment tools were compared to evaluate their concordance and to identify areas where efficiency in recording assessments might be improved. We found no statistical difference between the two tools in detecting symptomatic cerebral vasospasm. Substantial discrepancies in the documentation of observations were noted, particularly in the assessment of limb drift. Avoidance of these discrepancies may require further definition in the SNR tool. A qualitative component consisting of a review of the nurses' notes regarding neurological status in the patients' charts was conducted. It was demonstrated that nurses commonly document information in the progress notes that is already captured in the SNR. Further education of nurses in the use of assessment tools is therefore recommended to avoid redundancies and increase efficiency in recording clinical observations.

Subarachnoid haemorrhage and vasospasm: using physiological theory to generate nursing interventions.

Caring for critically ill patients with a subarachnoid haemorrhage and preventing its most prevalent and devastating complication, vasospasm, requires an in-depth understanding of the mechanisms which underpin the physiology of SAH. This is essential to provide appropriate nursing practice derived from theory. All too often practitioners are asked to follow unsubstantiated regimes without question of the origins of practices. This paper approaches the physiological theory underpinning the mechanisms surrounding subarachnoid haemorrhage and the altered cerebral and extracerebral dysfunction which can occur. Physiological theory is analysed to generate nursing interventions which may be individually tailored to provide comprehensive nursing care with a sound underpinning to its practice. The foundations of effective management of SAH lies within prevention, early diagnosis, and correction of complications [Neurosurg. Clin. North Am. 9 (3) (1998) 595]. In order for such identification to take place, it is essential to have an understanding of the physiological theory that underpins the basis of care interventions. These interventions should compliment all other theoretical input that influences patient care and nursing practice, contributing to a holistic, dynamically formulated plan of care.
