Treatment of SIADH is aimed at correcting dilutional hyponatremia, closely monitoring for electrolyte and weight changes, as well as administering medications to decrease fluid retention. This card will cover the nonpharmacologic interventions of monitoring of serum and urine osmolality, recording I&Os with daily weights, restriction of fluid intake, monitoring of cardiovascular and neurological status, as well as initiating seizure precautions. 5 KEY FACTS Ensuring that serum osmolality increases and urine osmolality decreases allows the provider to confirm that the patient is losing serum volume into the urine. Daily weights are the staple for monitoring fluid level in any patient. Carefully monitoring intake and output in these patients is also advised to prevent fluid overload. There are not many instances where we restrict fluid intake in patients. SIADH patients are placed on a fluid restriction of 1L/day to promote an increase of serum osmolality. Severe cases may be restricted to 500mL/day. Excess fluid volume in these patients causes shifts of electrolytes, especially sodium. Careful monitoring of these patient’s CNS function and cardiac status is imperative as these may deteriorate quickly. Patients with dilutional hyponatremia are at an increased risk for seizures and should be placed on seizure precautions to ensure safety as low sodium levels often precipitate seizures.

Is a condition that results from failure in the negative feedback mechanism that regulates inhibition and secretion of ADH. It produces excess ADH, resulting hypothermia and hypoosmolality of serum. The kidneys respond by reabsorbing water in the tubules and excreting sodium; thus the patient becomes severely water intoxicated. SIADH is most commonly caused by ectopic production of ADH by malignant tumors. It can be result of
CNS disorders, such as Guillain-Barre syndrome, meningitis, brain tumors, and head trauma. Pulmonary-related conditions, such as pneumonia, and positive pressure ventilation can cause SIADH. Pharmacologic agents such as general anesthetics, thiazine diuretics, oral hypoglycemics, chemotherapeutic agents, and analgesics are also associated with SIADH release. Excess fluid volume related to excessive amount of antidiuretic hormone secretion. image credit to : MEDICALIMAGES.ALLREFER.COM Outcome Criteria
Patient Management
What is the priority nursing intervention for patient with SIADH?Nursing care for SIADH
You will restrict fluids and replace sodium as ordered by the provider. Monitor for fluid volume excess. If the patient has too much fluid volume overload, that can lead to pulmonary edema which is life threatening, so it's important to monitor for that.
Which intervention would a nurse perform when caring for a client with syndrome of inappropriate antidiuretic hormone SIADH )?The most commonly prescribed treatment for SIADH is fluid and water restriction.
What should the nurse monitor for SIADH?For both DI and SIADH, you will be monitoring urine specific gravity, urine osmolality, serum sodium and serum osmolality. The patient may also receive testing to determine if the cause of the disorder is related to an underlying condition.
What nursing intervention to perform if their is excess secretion of ADH?Nursing Interventions and Rationales. Electrolyte supplements (potassium). Demeclocycline or lithium – stops the kidneys from responding to extra ADH.. |
