Are any local anesthetics safer than others?
No. When used properly, all currently available local anesthetic formulations are extremely safe and effective.
“Used properly” is the key phrase. Aspiration (twice) before injection (to minimize the risk from intravascular administration) and slow administration of the drug are vital. To determine potential contraindications to specific local anesthetics or additives, the patient’s medical history must be obtained and a physical evaluation completed before their use. The maximum dose of a drug should be determined for a given patient and not exceeded. The figures cited are maximum recommended doses. The stated maximum recommended dose should be decreased in patients with certain medical complications and in older individuals. Most systemic reactions to local anesthetics are entirely preventable.
Overdose reactions that have led to death or significant morbidity frequently result from the administration of too large a dose to a younger, lighter-weight, well-behaved patient requiring multiple quadrants of dental care or, much less commonly, after “accidental” intravenous administration. Psychogenic reactions, by far the most common adverse response to the administration of a local anesthetic, may be virtually eliminated through enhanced rapport with the patient, use of an atraumatic injection technique , placement of the patient in a supine position during injection, and ample doses of empathy.
