Syndrome of inappropriate antidiuretic hormones
DEFINITION
It is a syndrome characterised with hyponatremia, concentration of urine and dilution of blood.
SIADH causes the body yo retain fluid thus resulting in decreased electrolyte balance.
CAUSE
It is caused when hypothalamus is stimulated to produce excess amount of vasopressin which is an antidiuretic hormone that triggers the kidney to retain fluid in the tubules and excrete sodium.
Subjective data
Depression
Irritable
Muscle cramps
Fatigue
Nausea
Objective data
Vomiting
Seizures
Confusion
Edema
Tremors
Signs of volume overload
Hypothermia
Desired outcome
Patient will maintain normal electrolyte fluid and balance
Nursing diagnosis
Excess fluid volume related to excessive amount of antidiuretic hormone secretion.
Nursing interventions and rationale
Assess and monitor respiratory status, note changes in respiration.
Excess fluid volume can settle around the lungs and heart, monitor signs of congestion, and difficulty in breathing.
Continous ECG monitoring as changes in electrolyte balance can disrupt the electrical conductions in heart causes dysrhythmias
Administer medication and electrolyte supplements appropriately, medication such as potassium and lithium to stop kidneys from responding to extra ADH.
Monitor for retention through calculations of intake and output with daily weights at the same time on the same scale.
Monitor intake and output, as patient may be on fluid restriction to help balance intake and output.
