1. Indicações e resultados para o uso expandido da oclusão ressuscitativa por balão endovascular da aorta - REBOA.
RESUMO A oclusão ressuscitativa por balão endovascular da aorta (REBOA) é utilizada para controlar hemorragias não compressíveis do tronco como uma opção menos invasiva e com menos distúrbios fisiológicos quando comparado à toracotomia de emergência com clampeamento da aorta. Isso permite a melhora dos parâmetros hemodinâmicos até que a cirurgi

2. Perfil dos potenciais doadores de órgãos e fatores relacionados à doação e a não doação de órgãos de uma Organização de Procura de Órgãos.
RESUMO Objetivo: caracterizar o perfil dos potenciais e dos efetivos doadores de órgãos, e identificar os fatores relacionados a não efetivação da doação. Métodos: estudo retrospectivo transversal com coleta de dados das fichas da Organização de Procura de Órgãos do Hospital das Clínicas da Unicamp, referente ao período de janeiro de 2013 a a

3. Efeitos da oxigenoterapia hiperbárica após isquemia hepática segmentar normotérmica e reperfusão, em coelhos:: Avaliação bioquímica, morfológica e da microcirculação hepática pelo ultra-som contrastado
Interruption of blood flow to an organ or tissue (ischemia) and subsequent reperfusion lead to an acute inflammatory response that may cause significant cellular damage and organ dysfunction. It is called ischemia/reperfusion injury. Hepatic ischemia/reperfusion injury is characterized by circulatory and metabolic derangements, liver dysfunction and tissue d

4. Efeitos da hemodiluição normovolêmica aguda com Ringer lactato e hidroxietilamido na hipertensão intracraniana: estudo em cães com lesão criogênica do cérebro / Effects of acute normovolemic hemodilution with lactated Ringers solution and hydroxyethylstarch in intracranial hypertension: study in dogs with cryogenic brain injury
Objective: Brain injury is responsible for significant morbidity and mortality in trauma patients, but controversy still exists over optimal fluid management for these patients. This study aimed to investigate the effects of acute hemodilution with hydroxyethyl starch (HES) or lactated Ringers solution (LR) in intracranial pressure(ICP) and cerebral perfusio

5. Use of neuron-specific enolase for assessing the severity and outcome of neurological disorders in patients
Neuron-specific enolase (NSE) is a glycolytic enzyme present almost exclusively in neurons and neuroendocrine cells. NSE levels in cerebrospinal fluid (CSF) are assumed to be useful to estimate neuronal injury and clinical outcome of patients with serious clinical manifestations such as those observed in stroke, head injury, anoxic encephalopathy, encephalit

6. Cerebrospinal fluid enzymes in acute brain injury. 2. Relation of CSF enzyme activity to extent of brain injury.
The value of CSF enzyme estimations as indices of the extent of brain damage was studied in the experimental situation. Standard cold lesions of different severity were induced in cats. The activities of the enzymes CPK, HBDH, LDH, GOT, AND ChE were studied at half hour intervals in the cerebrospinal fluid (CSF). The ventricular and cisternal fluid pressure,

7. Deep intracerebral (basal ganglia) haematomas in fatal non-missile head injury in man.
Deep intracerebral (basal ganglia) haematomas were found post mortem in 63 of 635 fatal non-missile head injuries. In patients with a basal ganglia haematoma, contusions were more severe, there was a reduced incidence of a lucid interval, and there was an increased incidence of road traffic accidents, gliding contusions and diffuse axonal injury than in pati

8. Year in review 2008: Critical Care - trauma
Eleven papers on trauma published in Critical Care during 2008 addressed traumatic brain injury (TBI), burns, diagnostic concerns and immunosuppression. In regard to TBI, preliminary results indicate the utility of either magnetic resonance imaging (MRI) or ultrasound in measuring optic nerve sheath diameter to identify elevated intracranial pressure (ICP) a

9. The phosphodiesterase inhibitor rolipram delivered after a spinal cord lesion promotes axonal regeneration and functional recovery
Although there is no spontaneous regeneration of mammalian spinal axons after injury, they can be enticed to grow if cAMP is elevated in the neuronal cell bodies before the spinal axons are cut. Prophylactic injection of cAMP, however, is useless as therapy for spinal injuries. We now show that the phosphodiesterase 4 (PDE4) inhibitor rolipram (which readily

10. Within-breath modulation of left ventricular function during normal breathing and positive-pressure ventilation in man.
1. To investigate how intrathoracic pressure affects left ventricular function during normal breathing and positive-pressure ventilation, beat-by-beat measurements of left ventricular stroke volume (LVSV; pulsed Doppler ultrasound), heart rate and blood pressure were made in five normal subjects breathing actively and then undergoing passive positive-pressur

11. Erythropoietin prevents motor neuron apoptosis and neurologic disability in experimental spinal cord ischemic injury
The cytokine erythropoietin (EPO) possesses potent neuroprotective activity against a variety of potential brain injuries, including transient ischemia and reperfusion. It is currently unknown whether EPO will also ameliorate spinal cord injury. Immunocytochemistry performed using human spinal cord sections showed abundant EPO receptor immunoreactivity of ca
