The use of echocardiography is very useful in the evaluation, treatment, and follow-up of the patient in critical condition. Along with clinic and the stethoscope, it is a tool that complements the act of the physician faced with the diversity of etiologies that determine the state of shock and increase morbidity and mortality, especially in post-cardiac surgery patients, in whom there are no management emergency post-surgical algorithms. In view of this situation, at the National Institute of Cardiology Ignacio Chávez, a management algorithm has been made and improved in cardiac post-surgical patients: through focused ultrasonography, including transthoracic echography, pulmonary ultrasound, optic nerve ultrasound, and renal ultrasound by evaluating renal resistive indices. Several societies have created their protocols for addressing patients in critical condition, so in the institute, specifically in cardiovascular intensive therapy, has created the cardiac, cerebral, renal, optic nerve, and lung ultrasound study (CCROSS) protocol for the initial approach of these patients, and a study is currently taking place for its validation, reproducibility, and efficacy.

In this study we chose to measure optic nerve sheath diameter by sonography for diagnosis of elevated ICP in comparison to brain CT as our reference gold standard for detection of raised I...
Atrophy of the optic disk which may be congenital or acquired. This condition indicates a deficiency in the number of nerve fibers which arise in the RETINA and converge to form the OPTIC DISK; OPTIC NERVE; OPTIC CHIASM; and optic tracts. GLAUCOMA; ISCHEMIA; inflammation, a chronic elevation of intracranial pressure, toxins, optic nerve compression, and inherited conditions (see OPTIC ATROPHIES, HEREDITARY) are relatively common causes of this condition.
Conditions which produce injury or dysfunction of the second cranial or optic nerve, which is generally considered a component of the central nervous system. Damage to optic nerve fibers may occur at or near their origin in the retina, at the optic disk, or in the nerve, optic chiasm, optic tract, or lateral geniculate nuclei. Clinical manifestations may include decreased visual acuity and contrast sensitivity, impaired color vision, and an afferent pupillary defect.
Set of cell bodies and nerve fibers conducting impulses from the eyes to the cerebral cortex. It includes the RETINA; OPTIC NERVE; optic tract; and geniculocalcarine tract.
Benign and malignant neoplasms that arise from the optic nerve or its sheath. OPTIC NERVE GLIOMA is the most common histologic type. Optic nerve neoplasms tend to cause unilateral visual loss and an afferent pupillary defect and may spread via neural pathways to the brain.
The 2nd cranial nerve. The optic nerve conveys visual information from the retina to the brain. The nerve carries the axons of the retinal ganglion cells which sort at the optic chiasm and continue via the optic tracts to the brain. The largest projection is to the lateral geniculate nuclei; other important targets include the superior colliculi and the suprachiasmatic nuclei. Though known as the second cranial nerve, it is considered part of the central nervous system.
Chronic kidney disease (CKD), also known as chronic renal disease, is a progressive loss in renal function over a period of months or years. The symptoms of worsening kidney function are non-specific, and might include feeling generally unwell and experi...
