Perioperative ultrasound neuromonitoring: transcraneal Doppler and optic nerve.

Monitoring of the neurocritical in the perioperatory is in constant evolution. There are essentially two ultrasonographic application of neuromonitoring: the diameter of the sheath of the optic nerve and transcranial Doppler. Ultrasound-guided neuromonitoring can detect stenosis or occlusion of intracranial arteries, monitor the evolution of patients with vasospasm after subarachnoid hemorrhage, detect cerebral embolism, evaluate the cerebral collateral system, determine brain death, calculate indirectly Intracranial pressure and cerebral perfusion and helps in clinical decisions and early therapeutic interventions in neurocritical care.

[Nuevos conceptos de la reanimación hídrica intravenosa].

Antecedentes: La reanimación hídrica intravenosa es esencial en el manejo de los pacientes hospitalizados, en especial en aquellos con enfermedad aguda o crítica. En la actualidad se proponen cuatro premisas con cuatro indicaciones, cuatro preguntas y cuatro fases para la reanimación hídrica intravenosa.

Objetivo: El objetivo de esta revisión es dar a conocer esta propuesta de manejo en la reanimación hídrica intravenosa.

Point-of-care gastrointestinal and urinary tract sonography in daily evaluation of gastrointestinal dysfunction in critically ill patients (GUTS Protocol).

There is currently a lack of universally accepted criteria for gastrointestinal (GI) failure or dysfunction in critical care. Moreover, the clinical assessment of intestinal function is notoriously difficult and thus often goes unrecognized, contributing to poor outcomes. A recent grading system has been proposed to define acute gastrointestinal injury (AGI) in conjunction with other organ function scores (e.

[Metabolic control in the critically ill patient an update: hyperglycemia, glucose variability hypoglycemia and relative hypoglycemia].

Background: Metabolic changes of glucose in critically ill patients increase morbidity and mortality. The appropriate level of blood glucose has not been established so far and should be adjusted for different populations. However concepts such as glucose variability and relative hypoglycemia of critically ill patients are concepts that are changing management methods and achieving closer monitoring.
