Physicians and specially educated nurses administer intrathecal medications through a catheter surgically placed in the subarachnoid space or one of the ventricles of the brain. Intrathecal medication administration often is a long-term treatment.
This method of medication administration involves the infusion of medication directly into the bone marrow. It is used most commonly in infants and toddlers who have poor access to their intravascular space or when an emergency arises and IV access is impossible.
Epidural medications are administered in the epidural space via a catheter, which is placed by a nurse anesthetist or an anesthesiologist. This route is used for the administration of regional analgesia for surgical procedures. Nurses who have advanced education in the epidural route can administer medications by continuous infusion or a bolus dose.
Medications administered into the peritoneal cavity are absorbed into the circulation. Chemotherapeutic agents, insulin, and antibiotics are administered in this fashion.
A syringe and needle or a chest tube is used to administer intrapleural medications directly into the pleural space. Chemotherapeutic agents are the most common medications administered via this method. Physicians also instill medications that help resolve persistent pleural effusion to promote adhesion between the visceral and parietal pleura. This is called pleurodesis.
Intraarterial medications are administered directly into the arteries. Intraarterial infusions are common in patients who have arterial clots and receive clot-dissolving agents. A nurse manages 616a continuous infusion of the clot-dissolving agent and carefully monitors the integrity of the infusion to prevent inadvertent disconnection of the system and subsequent bleeding.
Other methods of medication administration that are usually limited to physician administration are intracardiac, an injection of a medication directly into cardiac tissue, and intraarticular, an injection of a medication into a joint.
