“Needle-Stick and IV Injuries”: Improper “IV Placement”, “Infiltration”, and “Extravasation”
Published .
“Infiltration” and “Extravasation” Mean Different Things
When an IV solution leaks into the tissue instead of remaining in the vein, clinicians often call leakage of a nonvesicant fluid “infiltration” and leakage of a tissue-damaging medication “extravasation.” Terminology varies by clinical context; radiology also uses “contrast-media extravasation” for contrast leaking from a vein. “Intravasation” is not the usual term for an IV leak into surrounding tissue. The substance, amount, location, and duration of leakage affect the potential injury.
How “Needle Placement” Can Cause Harm
Complications may follow repeated or traumatic punctures, an IV catheter that is misplaced or later moves, accidental arterial puncture, bleeding or a hematoma, direct nerve irritation or injury, or medication and fluid entering surrounding tissue. More serious injuries can include tissue damage, infection, impaired circulation, or nerve symptoms. These outcomes can occur despite appropriate technique, particularly where veins are fragile or a patient has other risk factors.
When an “IV Injury” May Raise a Negligence Question
Potential issues include whether a trained person selected and placed an appropriate catheter, whether placement and patency were checked, whether the line was secured, and whether the site and patient were monitored in a manner suited to the medication and circumstances. Once a patient reports pain, burning, tightness, swelling, or numbness—or staff observe a change—the response and any delay in stopping the infusion or assessing the site may matter. Drug- and contrast-specific protocols can guide the response. A difficult stick, infiltration, or extravasation alone does not prove substandard care.
“Who May Be Responsible” Depends on Each Person’s Role
A claim may involve the person who inserted or monitored the IV, a clinician who ordered the medication or contrast, radiology or infusion staff, and the facility. A facility’s training, staffing, equipment, policies, and escalation system may also be relevant. If a defective catheter, infusion device, or other product contributed, a separate product claim may require investigation. Liability depends on each party’s own duty or a supported employment or agency relationship; a complication does not make every person involved responsible.
“Evidence” in an IV Placement Case
Relevant records can include the medication or contrast order, insertion site and number of attempts, catheter size and type, patency checks, infusion pressure and rate, site assessments, complaints and responses, photographs, nursing and radiology notes, medication administration records, incident reports, and the timing of later symptoms or treatment. The medication or contrast identity and amount delivered can be important. Expert review may require nursing, radiology, pharmacology, vascular-access, or surgical knowledge depending on the injury. A workplace needlestick to a health-care worker is a separate occupational-exposure issue from a patient injury caused during IV care.
“Maryland Malpractice” and Causation
A Maryland claim generally requires proof that a provider or facility failed to meet the applicable standard of care and that the failure caused injury. Expert testimony is often needed to explain appropriate placement, monitoring, medication-specific precautions, and the cause and extent of tissue or nerve damage. Covered health-care malpractice claims are subject to HCADRO and qualified-expert requirements. Clinical guidelines inform expert analysis; they do not automatically decide the legal standard or the outcome of a particular case.
