The incidence of severe Local Anesthetic Systemic Toxicity (LAST) is estimated to be between 1 and 2 per 1,000 nerve blocks. Knowing what happens when lidocaine gets in the bloodstream is critical for patient safety during procedures using local anesthetics.

According to a 2022 review, severe systemic toxicity from lidocaine is a rare but serious complication, occurring in as few as 1 in 10,000 epidural procedures. When professionals administer a lidocaine injection improperly—such as injecting it directly into a blood vessel—the drug enters the bloodstream, potentially leading to a life-threatening condition called Local Anesthetic Systemic Toxicity (LAST).

While Botox is a remarkably safe and common procedure when administered correctly, serious side effects can occur if not managed by an experienced professional. Understanding **what happens if you accidentally inject Botox into a vein** is crucial, as this rare event can lead to the systemic spread of the neurotoxin, requiring immediate medical attention. For most cosmetic applications, the risk is minimal due to the low dosage, but proper technique is always essential.

While severe adverse effects from botulinum toxin injections are rare when administered correctly by a licensed professional, accidental injection of Dysport into a vein can lead to serious systemic complications. This mishap can cause the neurotoxin to spread beyond the intended area, potentially triggering botulism-like symptoms and other health issues.

An estimated 2% of patients receiving lidocaine with epinephrine for minor procedures experience an "adrenaline rush" with a rapid heartbeat. Discover the surprising reasons why your heart races after lidocaine and what it really means for your health.
