Local Anesthetic Systemic Toxicity (LAST)

Local Anesthetic Systemic Toxicity (LAST) occurs when local anesthetics, used to numb a specific area during medical procedures, enter the bloodstream and affect the entire body. This can happen due to accidental injection into a blood vessel or excessive doses. Symptoms may include ringing in the ears, seizures, heart irregularities, or even loss of consciousness. LAST is a serious condition that requires immediate medical attention. Treatment focuses on stabilizing the patient and minimizing complications, highlighting the importance of careful administration of local anesthetics by healthcare professionals.
