Abstract

Point-of-care ultrasound is modifying conducts in emergency care. The various medical specialties, in addition to traditional indications in cases of multiple trauma, are using this technique for rapid diagnosis at the bedside without patient mobilization and without radiation. Point-of-care ultrasound in neurocritical patients, through its transorbital window, can estimate the intracranial pressure by a non-invasive method. Through the measurement of the diameter of the optic nerve sheath 3 mm posterior to the retina, the intracranial pressure is estimated if the value of the diameter is > 5 mm, as it has been verified in other studies. The present article describes the most current data on this topic, and it also highlights the need for more multicentric and randomized trials to determine the correct cut-off points that represent the high sensibility and specificity of the method.

Resumo

A ultrassonografia point-of-care está modificando as condutas na sala de emergência. As diversas especialidades, além das indicações tradicionais ao politraumatizado, estão utilizando esta técnica para um rápido diagnóstico à beira do leito, sem a necessidade de mobilização do paciente e sem irradiação. Nos pacientes neurocríticos, a ultrassonografia point-of-care, através de sua janela transorbital, oferece uma técnica não invasiva para avaliação da pressão intracraniana. Por meio da medida do diâmetro da bainha do nervo óptico 3 mm posterior à retina, estima-se a pressão intracraniana se o valor desse diâmetro for superior a 5 mm, conforme verificado em alguns estudos. Este artigo apresenta os dados mais atuais sobre o tema, destacando, ainda, a necessidade de mais estudos multicêntricos, randomizados, para a correta determinação dos valores de corte que representem a alta sensibilidade e especificidade do método.
