Drug Assesment ::

 Assessment/Interventions

  • Obtain patient history, including drug history and any known allergies.
  • Monitor cardiac status, BP, pulse and respiration rate frequently, especially with IV administration. Fall in BP may occur with repeated use of metaraminol. Check BP every 5 min until stabilized and then check every 5 min throughout therapy.
  • Notify physician if significant changes or arrhythmias occur.
  • Monitor I&O.
  • Monitor patient for sympathomimetic side effects such as: izziness, headaches, restlessness, faintness, anxiety, flushing and apprehension.
  • Monitor for hypertensive crisis and intracranial hemorrhage if given with MAO inhibitors, furazolidone, rauwolfia alkaloids and methyldopa.
  • Observe for metabolic acidosis with prolonged use.
  • When infusion is to be discontinued, gradually reduce flow rate.
  • Document any side effects or adverse reactions, including arrhythmias, hypertension or hypotension after stopping drug, cardiac arrest and nausea.
OVERDOSAGE: SIGNS & SYMPTOMS
  Convulsions, severe hypertension, cerebral hemorrhage, cardiac arrhythmias, headache, constricting sensation in chest, nausea, vomiting, euphoria, sweating, pulmonary edema, MI, cardiac arrest, convulsions

Drug Storage/Management ::

 Administration/Storage

  • Dilute in normal saline or D5W. Use large veins to decrease irritation and/or tissue necrosis at parenteral administration sites. If given directly IV, follow with infusion to decrease possibility of necrosis.
  • After administration, observe patient for effects before repeating dose. Pressor effects occur 1–2 min after IV dose, 10 min after IM dose, and 5–20 min after SC dose.
  • Avoid IM injection to prevent tissue sloughing at injection site.
  • Use infusion solutions within 24 hrs of mixing.
  • Avoid exposing drug to excessive heat. Protect from light.

Drug Notes ::

 Patient/Family Education

  • Alert patient to the possible problems of extravasation. Instruct patient to report symptoms such as paresthesia, respiratory distress, chest pain, palpitations or irritation or pain at injection site.
  • Educate patient and family regarding sympathomimetic side effects.
