28 hours ago · Introduction- Good day!I am Nurse Ruru, a nurse. I'm calling because because I want or report one of my patient whos possibly experiencing digoxin toxicity. Situation- The patients name is KEOLA AKANA, a 70 year old, male who is stable but in danger of deterioration.. Background- The patient had a past medical history of Heart Failure without current medication. >> Go To The Portal
Serum level cannot be the sole criterion in diagnosing digoxin toxicity. Nevertheless, raised serum digoxin levels especially above 3 ng/ml, in the presence of suggestive clinical features is strongly suggestive of toxicity. Adolescent Adult Arrhythmias, Cardiac / chemically induced
Hyperkalaemia will improve with giving digoxin-specific antibody fragments, and conventional treatments such as calcium will generally be unnecessary or harmful. 15 If the patient has severe hypokalaemia and digoxin toxicity, it is important to correct the serum potassium.

In adults and older children, first symptoms of toxicity usually include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and other arrhythmias. In infants and small children, first signs of overdose are usually cardiac arrhythmias.
for a patient with hypokalemia? Nutritional Implications: low sodium and high potassium diet. problems, heart palpitations, muscle aches and stiffness, tingling and numbness, dyspnea, tachycardia, tachypnea, decreased bowel sounds and hyperglycemia.
Pathophysiology – Digoxin Toxicity Digoxin toxicity causes hyperkalemia, or high potassium. The sodium/potassium ATPase pump normally causes sodium to leave cells and potassium to enter cells. Blocking this mechanism results in higher serum potassium levels.
Dietary modification may be necessary for patients with excessive potassium losses (eg, diuretic or laxative use) or patients with hypokalemia who are at increased risk, such as those receiving digoxin. In general, a low-sodium and high-potassium diet is appropriate.
Diagnosis of Hyperkalemia and Hypokalemia Blood test. A blood test is performed to check the levels of electrolytes in the blood including potassium. Urine test. Urinalysis can also show the presence of potassium in the urine.
How is hypokalemia diagnosed? Your healthcare provider will check your potassium level through a blood test. The normal potassium level for an adult ranges from 3.5 to 5.2 mEq/L (3.5 to 5.2 mmol/L). Potassium levels between 3 and 3.5 mEq/L (3 to 3.5 mmol/L) are considered mild hypokalemia.
Mild hypokalemia doesn't cause symptoms. In some cases, low potassium levels can lead to arrhythmia, or abnormal heart rhythms, as well as severe muscle weakness.
Signs & Symptoms However, symptoms of hypokalemia may include attacks of severe muscle weakness, eventually leading to paralysis and possibly respiratory failure. Muscular malfunction may result in paralysis of the bowel, low blood pressure, muscle twitches and mineral deficiencies (tetany).
In hypokalemia, the level of potassium in blood is too low. A low potassium level has many causes but usually results from vomiting, diarrhea, adrenal gland disorders, or use of diuretics. A low potassium level can make muscles feel weak, cramp, twitch, or even become paralyzed, and abnormal heart rhythms may develop.
Monitoring should continue after treatment because of the small risk of rebound toxicity. Restarting therapy should take into account the indication for digoxin and any reasons why the concentration became toxic. Key words: arrhythmia, digoxin, digoxin-specific antibody fragments. Introduction.
This should be delayed until all the digoxin-specific antibody fragments have been cleared, which will take up to a week, but far longer in the presence of renal dysfunction.18,22.
Each ampoule contains 40 mg of powdered digoxin-specific antibody and is reconstituted with 4 mL of water. This can be given as a slow push in cardiac arrest, but otherwise the total dose is diluted further with normal saline and infused over 30 minutes.
Digoxin-specific antibody fragments are used when there is a risk of a life-threatening arrhythmia.
It can also trigger fatal arrhythmias. There is a range of indications for using digoxin-specific antibody fragments. The amount ingested and serum digoxin concentration help to determine the dose required, but are not essential. Digoxin-specific antibody fragments are safe and effective in severe toxicity.
This article has been cited byother articles in PMC. Summary. Digoxin toxicity can emerge during long-term therapy as well as after an overdose. It can occur even when the serum digoxin concentration is within the therapeutic range.
There are no evidence-based guidelines for the management of mild to moderate toxicity so there is a wide variation in treatment.13Severe toxicity requires hospital admission and consideration of the need for digoxin-specific antibody fragments.
You have a headache, confusion, anxiety, or hallucinations. You feel restless, weak, or depressed. You have any changes in vision such as seeing halos around bright objects. You have difficulty breathing. You have a fast, slow, or irregular heartbeat, or palpitations (fast, forceful heartbeats in an irregular rhythm).
Certain medical conditions such as kidney disease, hypothyroidism, or heart disease. Low blood levels of potassium or magnesium. High blood levels of potassium or calcium. Use of herbal supplements that contain substances similar to digoxin. Use of medicines that interact with digoxin such as diuretics, calcium channel blockers, ...
Contact your healthcare provider if you miss a dose or you have any questions about how to take digoxin. Do not stop taking digoxin unless your healthcare provider has told you to. You may have increased irregular heartbeats if you stop taking digoxin.

Your patient, who is 7 years old is due to take her Digoxin dose. What patient finding would prompt you to hold the upcoming Digoxin dose and notify the physician immediately?
This can be caused by too much medication, high doses, or lower tolerance to the drug. Checking serum levels during digoxin therapy is such an important step in what to monitor when your patient is taking digoxin.
