Secondary Outcomes (4)

  • reduction of icp

    1 hours, 6 hours, 24hours

  • GCS

Study Arms (2)

Group M (Mannitol)

ACTIVE COMPARATOR

used ultrasonography to assess the optic nerve sheath diameter from Baseline or Immediately before mannitol therapy. Then added mannitol with Follow-up ONSD, 2 hours, 6 hours,24 hours using 20% Mannitol Dose: 0.5-1 g/kg IV over 15-20 minutes.

Drug: Mannitol (20%)

Group H (Hypertonic Saline)

ACTIVE COMPARATOR

used ultrasonography to assess the optic nerve sheath diameter from Baseline or Immediately before hypertonic saline therapy. Then added hypertonic saline with Follow-up ONSD, 2 hours, 6 hours,24 hours used 3% Hypertonic saline at dose: 2-3 mL/kg IV over 15-20 minutes

Drug: Hypertonic Saline ( 3% Sodium Chloride Saline)

Interventions

compare the efficacy of mannitol in reducing intracranial pressure, as assessed by serial optic nerve sheath diameter (ONSD) ultrasound measurements, in patients with traumatic brain injury.

Group M (Mannitol)

compare the efficacy of hypertoic saline in reducing intracranial pressure, as assessed by serial optic nerve sheath diameter (ONSD) ultrasound measurements, in patients with traumatic brain injury.

Group H (Hypertonic Saline)
