Severe systemic toxicity from local anesthetics like lidocaine occurs in up to 1 in every 2,000 peripheral nerve blocks. So, **what happens if lidocaine is absorbed into the bloodstream**? It can lead to a dangerous condition called Local Anesthetic Systemic Toxicity (LAST).

While the term "Novocaine" is widely used, the drug procaine was largely replaced by modern anesthetics like lidocaine decades ago. The most common and harmless heart-related side effect, a rapid heartbeat, is actually caused by the added epinephrine, not the anesthetic itself.

Systemic toxicity is the most significant adverse effect of lidocaine, a common local anesthetic, and it can affect the central nervous system and heart. While many side effects are mild and localized, severe complications can occur if the medication is absorbed into the bloodstream in large amounts, particularly from injections or overuse of topical forms.

Of all local anesthetics, bupivacaine is associated with the highest incidence of cardiac toxicity and is among the most challenging to treat in cases of systemic toxicity [1.2.1, 1.2.3, 1.2.6]. This article explores which local anesthetic drug has the highest cardiotoxicity and why.

Pharmacological studies and clinical evidence consistently demonstrate that bupivacaine is significantly more cardiotoxic than lidocaine, with its higher potency and different binding kinetics on cardiac sodium channels contributing to its increased risk. The distinction between these two commonly used local anesthetics is critical for anesthesiologists and other healthcare providers to manage local anesthetic systemic toxicity (LAST) effectively.

While local anesthetic systemic toxicity (LAST) is a rare but life-threatening complication, with an estimated occurrence of 7.5 to 20 per 10,000 peripheral nerve blocks, it can lead to cardiotoxicity. This article examines the critical question: Does lidocaine cause cardiotoxicity, exploring the conditions under which this risk arises and how it is managed safely?

Local anesthetics are generally very safe and serious problems are rare, but understanding the potential risks is vital for patient safety. This guide details what are the side effects of local anaesthetic in the cervix, from minor, temporary effects to the very rare systemic complications associated with paracervical blocks.

While generally safe, adverse drug reactions to local anesthetics (LA) occur in an estimated 2.5% to 10% of cases [1.6.1]. Understanding 'What is a common side effect of local anesthetics?' involves recognizing both minor, localized issues and rare, systemic complications.

Local Anesthetic Systemic Toxicity (LAST) is a rare but potentially life-threatening complication that occurs when local anesthetics enter the systemic circulation. For healthcare providers and patients alike, recognizing what are the early signs of local anesthetic toxicity is critical for preventing a medical emergency.

The long-acting local anesthetic bupivacaine is known for its significantly higher systemic toxicity, particularly cardiotoxicity, compared to other agents like lidocaine. For clinicians and patients alike, understanding which anesthetic has the highest risk for toxicity is a critical component of ensuring patient safety.
