Dental Anesthesia Preanesthetic Evaluation

Dental Anesthesia

• Clinicians must assess patient tolerance (physical and psychological) for planned dental procedures before starting.
• This is crucial when administering any drug, including analgesics, anxiolytics, inhalation sedation (N2O-02), sedative-hypnotics, and local anesthetics.
• Local anesthetics affect excitable membranes (CNS and CVS).
• Metabolism (primarily in the liver for amides, or blood for esters) must be considered.
• Patient medical and psychological history is essential.

Preanesthetic Evaluation

• A comprehensive evaluation includes complete medical/dental history, dialogue history, and physical and psychological examination.
• Medical history questions (e.g., significant illnesses, operations, allergies, current medications, heart conditions, respiratory issues, etc.) must be considered for local anesthesia implications.
• Pre-anesthetic data determines if local anesthetic or vasoconstrictors are appropriate and if medical consultation is needed.
• Patient's tolerance to supine position is crucial.
• Stress-reduction protocols may be helpful for anxious patients.

Medical Examination

• Visual examination helps assess patient general well-being by observing posture, body movements, speech patterns, and skin conditions.
• Vital signs (blood pressure, pulse, respiration, body temperature, oxygen level/saturation) are taken, monitored, and recorded.
• Data is used to determine appropriate treatment and anesthetic selection.

Risk Assessment

• After a thorough medical history and vital signs are collected, evaluate patient tolerance for dental treatment and local anesthetics.
• Modifications to treatment or anesthetic selection may be needed.
• The ASA (American Society of Anesthesiologists) classification system is used to assess patient anxiety and medical risk.
