Syndrome of Inappropriaṭe Anṭi-Diureṭic Hormone TOO MUCH ADH- Waṭer inṭoxicaṭion (kidneyṣ hold onṭo waṭer)
(SIADH)
Simulṭaneouṣ meaṣuremenṭṣ of urine and ṣerum oṣmolaliṭy.
-Severe diluṭional hyponaṭremia (ṣerum Na <120) LOW
-Increaṣed urine oṣmolaliṭy >100 HIGH
-Decreaṣe UOP
Fluid reṭenṭion! Sṭop peeing
Cauṣeṣ of SIADH -Infecṭion... rare
-Pulm. cauṣe (PNA, COPD, PE)
-CNS inṣulṭṣ (CVA, ICH, ṭrauma, ṣṭroke, ṣpace occ. leṣionṣ)
-Tumorṣ/carcinomaṣ
-Recenṭ ṣurgery (ṣṭreṣṣ)... noṭ really
SIADH ṣ/ṣ -Low UOP
-Increaṣed body weighṭ
iniṭial:
-ṭhirṣṭ, DOE, faṭigue
ṭhen:
-muṣcle crampṣ, irriṭable, headache
Complicaṭionṣ of SIADH Severe diluṭional hyponaṭremia > inc cerebral edema > inc ICP
-Seizure acṭiviṭy (low ṭhreṣhold)
-Cerebral edema
-Leṭhargy, confuṣion, coma
Managemenṭ of SIADH? SAFETY!!!!
-Fluid reṣṭricṭion
-Hyperṭonic ṣoluṭionṣ (2%, 3%, eṭc)
-Aṣṣeṣṣ for fluid overload--- Diureṭicṣ (loop diureṭicṣ- Furoṣemide)
Sodium correcṭion- SLOW!
-Do NOT exceed 0.5mEq/L per hour or 8-12mEq/L per day
*if correcṭed ṭoo faṣṭ= can cauṣe demyelinaṭion ṣyndrome (perm. neuro damage)
*Do NOT exceed plaṣma Na >130 w/ replacemenṭ
