Is cerebral desaturation during beachchair anaesthesia really an indicator of cerebral injury?

چکیده
de la vía aérea ante una cirugía de estimada corta duración. Tras la revisión quirúrgica y el diagnóstico de lesión bronquial no susceptible de reparación inmediata se barajaron múltiples opciones para el mantenimiento de la vía aérea como las que proponen los autores. Decidimos no intercambiar el tubo orotraqueal convencional por otros dispositivos por las razones argumentadas en nuestro primer artículo. No obstante, tal y como apuntan los autores en su contestación, el desarrollo de hipoxemia durante la ventilación unipulmonar es frecuente por lo que su monitorización exhaustiva es imperativa, y especialmente en casos como el descrito donde la ventilación unipulmonar se mantuvo durante 48 h. Si se presentase dicha complicación, y en caso de no mejoría con las maniobras ya mencionadas sobre el pulmón ventilado, hubiéramos considerado el cambio de dispositivo para poder realizar alguna intervención sobre el pulmón no ventilado como apuntan los autores. Nos gustaría concluir que existen múltiples opciones para el manejo de casos similares como el expuesto que sin duda tendrían éxito, pero pensamos que debemos aplicar el sentido común a nuestra práctica diaria y siguiendo el principio de «primum non nocere», no elevar la complejidad de nuestras técnicas mientras estas no sean necesarias.

Effect of phenylephrine on the haemodynamic state and cerebral oxygen saturation during anaesthesia in the upright position.
BACKGROUND The upright sitting or beachchair position is associated with hypotension, risk of cerebral hypoperfusion, and cerebral injury. We hypothesized that by increasing arterial pressure with phenylephrine administration, cerebral perfusion, and postoperative recovery would be improved. METHODS Thirty-four patients undergoing elective shoulder surgery were randomized to receive either sa...
متن کاملCerebral oxygen desaturation during one-lung ventilation: correlation with hemodynamic variables.
PURPOSE Cerebral desaturation occurs frequently in patients undergoing one-lung ventilation for thoracic surgery. The mechanism of this desaturation is unclear regarding its etiology. The objective of this study was to investigate whether or not decreases in cerebral oxygen saturation associated with one-lung ventilation were a consequence of decreased cardiac output. METHODS A blinded observ...

Objective(s): Carthamus tinctorius L. (CT) or saffloweris widely used in traditional Chinese medicine. This study investigated the effects of CT extract (CTE) on ischemia–reperfusion (I/R) brain injury and elucidated the underlying mechanism. Materials and Methods: The I/R model was conducted by occlusion of both common carotid arteries and right middle cerebral artery for 90 min followed by 24...
متن کاملMathematical model for describing cerebral oxygen desaturation in patients undergoing deep hypothermic circulatory arrest.
BACKGROUND Surgical treatment for aortic arch disease requiring periods of circulatory arrest is associated with a spectrum of neurological sequelae. Cerebral oximetry can non-invasively monitor patients for cerebral ischaemia even during periods of circulatory arrest. We hypothesized that cerebral desaturation during circulatory arrest could be described by a mathematical relationship that is ...
متن کاملCognitive function after sevoflurane- vs propofol-based anaesthesia for on-pump cardiac surgery: a randomized controlled trial.
BACKGROUND Cognitive dysfunction is a frequent complication after cardiac surgery and has been found to be associated with decreases in cerebral oxygen saturation measured with near-infrared spectroscopy. Sevoflurane has neuroprotective properties in vitro and in animal models. This study was designed to determine cognitive and clinical outcomes after sevoflurane- compared with propofol-based a...
