Summary

Measurement of the diameter of the sheath of the optic nerve in patients hospitalized in intensive care, with increased intracranial pressure (\> 20mmHg) as a substitute measure for diagnosis and follow-up before and after different non-invasive strategies.

Three groups were created in which, through strategies already proven and non-invasive (mannitol, hypertonic solution 7.5% NaCl, reverse trendelenburg) to decrease the intracranial pressure, the optic nerve diameter measurement was performed and simultaneously the investigators monitored intracranial pressure through an intraventricular catheter continuously to determine if both correspond

Conditions

  • Intracranial Hypertension
  • Optic Nerve Sheath Diameter

Interventions

DIAGNOSTIC_TEST

optical nerve sheet diameter

The ONSD in each eye was measured vertically and horizontally 3 mm behind the optic disc, with the two values averaged. No pressure was applied to the orbit. At each time point, measurements were taken within 5 min. The measurements were made before (T1) and after some of the strategies according to group 30 min (T2), 60 min (T3), and 90 min (T4).
