Q

SIADH

A

Syndrome of inappropriate antidiuretic hormone
SI = Soaked Inside
Stop urinating
Sticky and thick urine = high urine specific gravity 1.030 +
Low and liquid labs
Hypo osmolality (low)
Hyponatremia below 135 na+
Sodium low (headache Early sign)
Seizures (from low sodium, headache, confusion)
Server high blood pressure (edema)
stop all fluids + give salt + diuretics
(no IV or drinking) unless it is IV 3% saline + eat salt
