Feedback:
Adverse effects of local anesthetics are associated with the route of administration and the amount of drug that is absorbed systemically. These effects are related to the blockade of nerve depolarization throughout the system. Effects that may occur include central nervous system effects such as headache (especially with epidural and spinal anesthesia), restlessness, anxiety, dizziness, tremors, blurred vision, and backache; gastrointestinal (GI) effects such as nausea and vomiting; cardiovascular effects such as peripheral vasodilation, myocardial depression, arrhythmias, and blood pressure changes, all of which may lead to fatal cardiac arrest; and respiratory arrest. There is no such problem as malignant hypothermia (the condition is malignant hyperthermia) and pain may be caused by the procedure but not the anesthetic.
