Efficacy of Thyroid Hormone Replacement for Secondary Hypothyroidism Following Intracerebral Hemorrhage

Upon discovering low T3 or low T4 levels, administer oral levothyroxine sodium tablets daily. If accompanied by a decrease in TSH, the regimen is 100μg qd (for individuals weighing \<75kg) or 150μg qd (for individuals weighing \>75kg). If not accompanied by a decrease in TSH, the regimen is 50μg qd. However, if thyroid function does not significantly improve within 3 days of medication, the regimen is adjusted to 100μg qd. Treatment should continue until transfer out of the NICU or discharge, with a minimum duration of 7 days.

Patient will not receive the oral levothyroxine sodium tablets.
