Intraventricular injection
Intraventricular injection, also called intracerebroventricular (ICV) injection, delivers a drug directly into the brain's ventricular cerebrospinal fluid, bypassing the blood-brain barrier, often through an Ommaya reservoir.
Iontophoresis
Iontophoresis is a drug delivery method that uses a small electric current to push charged drugs through the skin, and stimulates sweating for the cystic fibrosis sweat test.
Jejunal feeding
Jejunal feeding is enteral nutrition delivered through a tube whose tip lies in the jejunum, used when gastric feeding is not tolerated or complicated by severe reflux.
Joint injection
A joint injection is a procedure in which a needle is placed into a joint space to inject medication or aspirate fluid, to diagnose or treat pain and inflammation.
Local corticosteroid injection
Local corticosteroid injection delivers a corticosteroid, usually with a local anesthetic, directly into an affected joint, tendon sheath, bursa, or epidural space to reduce local inflammation and pain.
Mesotherapy
Mesotherapy is an injection technique that delivers small amounts of drugs, vitamins, or other substances into the dermis for pain relief, skin rejuvenation, and localized fat reduction.
Nasal administration
Nasal administration is a drug delivery route giving medications through the nose as sprays, drops, or powders, used for decongestants, migraine drugs, vaccines, and emergencies like naloxone.
Parenteral Infusions
Parenteral infusions deliver fluids, nutrients, or medications by non-enteral routes, chiefly intravenous, also subcutaneous, intramuscular, and intradermal. Distinguished by osmolarity-based access choice, filtration requirements, and home OPAT self-administration.
Pulsatile insulin
Pulsatile insulin is a method of delivering insulin in rapid, repeated pulses to mimic the pancreas's natural oscillatory secretion, tested intravenously and intraperitoneally in diabetes.
Punctures
Punctures (MeSH D011677), needle incisions of tissue for diagnostic or therapeutic procedures, including vascular access, micropuncture, lumbar puncture, and biopsy; Seldinger technique and ultrasound guidance.
Self Administration
Self Administration: a person administering a drug or biomedical intervention to themselves, under physician direction (MeSH D012646, 1977) or per WHO self-care definitions; distinct from self-medication, spanning hospital SAM schemes, OPAT, contraception, and addiction research.
Spinal Infusions
Spinal infusions deliver medication via needle or catheter into the epidural cavity or spinal sac (intrathecal, CSF). Used for labor, surgical, cancer, and chronic pain analgesia and intrathecal baclofen for spasticity, via externalized catheters or implantable pumps.
Spinal Injections
Spinal injections deliver local anesthetic, steroids, or both into epidural, facet, or sacroiliac structures to diagnose or treat spine pain. First used around 1900; 2025 BMJ guideline recommends against most uses for chronic non-cancer spine pain.
Subconjunctival injection
A subconjunctival injection places medication into the space between the conjunctiva and sclera of the eye, delivering a drug depot that diffuses through the sclera to ocular tissues.
Subcutaneous immunotherapy
Subcutaneous immunotherapy (SCIT) is an allergy treatment injecting increasing allergen doses under the skin to induce immune tolerance, used for rhinitis, asthma, and venom allergy.
Subcutaneous infusion
Subcutaneous infusion, also called hypodermoclysis, is a method of delivering fluids or medications into subcutaneous tissue, used mainly for mild to moderate dehydration in older adults.
Subcutaneous injection
A subcutaneous injection delivers medication into fatty tissue beneath the skin, a less invasive route than intravenous dosing that can be performed at home and provides slower, sustained absorption.
Transanal irrigation
Transanal irrigation (TAI) is a bowel management technique in which water is introduced into the rectum and colon to provoke emptying, treating chronic constipation, fecal incontinence, and neurogenic bowel dysfunction.
Trigger point injection
Trigger point injection is a pain medicine procedure in which a needle, usually with local anesthetic, is inserted into a muscle trigger point to relieve pain.
Ultrasound-guided injection
Ultrasound-guided injection is a procedure delivering corticosteroids or anesthetics into joints, tendon sheaths, bursae, or nerves while ultrasound imaging shows the needle tip in real time, improving accuracy over blind landmark-guided injections.
