Can You Administer IV Fluids on the Affected Side of a Stroke Patient?

Understanding IV Administration in Hemiplegic Patients

When it comes to intravenous (IV) therapy for individuals who have suffered a stroke and developed hemiplegia—paralysis on one side of the body—medical professionals must exercise caution. While it is not strictly prohibited to administer IV fluids on the affected side, it is generally advised to avoid doing so whenever possible, especially in the lower limbs. The primary reason lies in the compromised physiological functions of the paralyzed limb.

Why the Paralyzed Limb Is at Higher Risk

Muscle tone and circulation are significantly reduced after a stroke-induced paralysis. The muscles on the affected side lose their normal contractile ability, which plays a crucial role in assisting venous blood return toward the heart. Without this "muscle pump" effect, blood flow slows down considerably, increasing the risk of fluid accumulation and swelling (edema) in the dependent limb.

The Dangers of Lower Limb IV Infusions

Administering IV fluids through veins in the lower extremities—particularly on the weakened or paralyzed side—poses additional risks. The leg veins are naturally longer and more prone to blood stasis compared to those in the arms. When combined with immobility and poor muscle activity, this creates an ideal environment for deep vein thrombosis (DVT), a condition where dangerous blood clots form in the deep veins of the legs.

Potential for Life-Threatening Complications

One of the most serious complications of DVT is pulmonary embolism (PE). If a clot dislodges and travels through the bloodstream to the lungs, it can block a major artery, leading to sudden shortness of breath, chest pain, and even death if not treated promptly. This risk makes the choice of IV site critically important in stroke recovery care.

Best Practices for IV Therapy in Stroke Patients

Whenever feasible, healthcare providers should prioritize using the unaffected (non-hemiplegic) upper limb for IV access. The arms have shorter venous pathways, better circulation, and are less susceptible to clot formation. Additionally, patients and caregivers should be educated about signs of swelling, redness, warmth, or pain in the limbs—early warning signals of potential vascular complications.

In emergency situations where no other viable access points are available, temporary use of the affected side may be acceptable under close monitoring. However, this should never become a routine practice. Proactive planning and careful assessment can significantly reduce preventable complications during the rehabilitation phase of stroke survivors.
