Introduction
Adverse effects of anesthetic agents include the following: Local anesthetics or nerve block agents—such as lidocaine and ropivacaine, the most commonly used agents—can cause acute local anesthetic toxicity when administered inappropriately, in excessive doses, or inadvertently intravascularly. Primary manifestations include neurotoxicity and cardiotoxicity; in severe cases, cardiovascular collapse may occur.
In daily life, surgery is sometimes required due to certain medical conditions. During surgery, anesthetic agents are administered. What are the side effects of anesthetics?
What Are the Side Effects of Anesthetics?
Side effects of anesthetic drugs include the following: Local anesthetics and nerve block agents—such as lidocaine and ropivacaine, the most commonly used agents—may cause acute anesthetic toxicity if administered inappropriately, in excessive doses, or inadvertently injected into the bloodstream. Primary manifestations include neurotoxicity and cardiotoxicity; in severe cases, cardiovascular collapse may occur, necessitating immediate initiation of toxicology and controlled-substance emergency protocols.
General anesthetics comprise three categories of drugs: sedatives, analgesics, and neuromuscular blocking agents. All three classes are used concurrently during general anesthesia to ensure patient sedation, analgesia, unconsciousness, and muscle relaxation. The risk of adverse effects depends significantly on the clinical context—particularly whether administration is performed by a well-trained, board-certified anesthesiologist. Therefore, both local and general anesthetics are considered safe when administered under the supervision of qualified anesthesiologists with appropriate monitoring and protective measures in place.
Potential adverse reactions may involve the respiratory and circulatory systems—for example, apnea, atelectasis, or cardiac arrest. Thus, extreme caution must be exercised when administering anesthetics. Administration should always be performed exclusively by qualified physicians to minimize the risk of adverse effects.
