The intraoperative PtiO2 monitoring, combined with neurophysiologic monitoring during aneurysm surgery offers a fast and trustworthy form of early detection of ischemic phenomena caused by bad positioning of the surgical clip.

Recent advances in regional cerebral monitoring in the neurocritical patient: brain tissue oxygen pressure monitoring, cerebral microdialysis and near-infrared spectroscopy Summary The long term outcome of head-injured patients depends not only on the primary brain lesions but also to a large extent on the secondary lesions. The diagnosis of many secondary lesions, and specially that of brain ischemia, is based on simultaneous monitoring of several intracranial and systemic variables. Continuous intracranial pressure (ICP) monitoring is currently considered indispensable in the management of all patients with a severe head injury and intracranial lesions. However, the information provided by this technique is insufficient to diagnose some of the complex physiopathological processes that characterize traumatic brain lesions. Consequently, the use of methods to estimate cerebral blood flow such as transcranial Doppler and jugular oximetry to complement ICP monitoring is becoming increasingly widespread. Nevertheless, determining the effect of tissue lesions and therapeutic measures on cerebral metabolism currently requires direct access to the brain parenchyma at the bedside. In this review we focus on three methods of regional cerebral monitoring: oxygen tissue pressure (PtiO 2) monitoring, microdialysis and near-infrared spectroscopy. The bases of each method and reference values for the varia
Las fotografías tomadas por Antoni Campañà (1906-1989) durante la Guerra Civil española estuvieron ocultas durante más de ochenta años hasta su descubrimiento en otoño de 2018. Este importantísimo hallazgo aporta una nueva mirada a la Barcelona en guerra y revolución ofreciendo material fotográfico complementario y desconocido de sucesos de gran importancia histórica como “la Desbandá” andaluza de 1937, las protestas por la escasez alimentaria o los efectos de los bombardeos nacionales, así como retratos inéditos de los milicianos anarquistas o de figuras como Joan García Oliver. De los más de 5000 negativos de guerra inéditos descubiertos, en este trabajo analizamos diez fotografías representativas del autor, su estilo y la época que retrata.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
