    Study Notes

    Complications of Local Anesthesia

    • Temporary loss of sensation or abnormal sensation is referred to as paresthesia.
    • Facial nerve paralysis can occur as a complication of local anesthesia, particularly with improper administration.
    • A burning sensation at the injection site can indicate irritation or an unsuitable technique.

    Needle Breakage

    • Needle breakage can occur due to excessive force during injection or manipulating the needle.
    • Prevention methods include using proper techniques and choosing appropriate needle types.
    • Smaller gauge needles, such as 30-gauge needles, are more prone to breakage.
    • Common scenarios for needle fractures involve bending or excessive manipulation when the needle is inserted in the bone.
    • Needles used for inferior alveolar nerve block should not be short needles to prevent breakage.

    Pain and Burning Sensation on Injection

    • Pain during injection can be caused by factors such as rapid administration of the anesthetic.
    • To prevent pain on injection, techniques include anesthetic warming and slower injection rates.
    • A burning sensation during local anesthesia can stem from acidic solutions or temperature.
    • Rapid onset of burning sensation can be exacerbated by a low pH in the local anesthetic solution.
    • Contamination of the local anesthetic can also contribute to the burning sensation on injection.

    Onpharma's Onset

    • Onpharma’s Onset is designed to enhance the comfort of local anesthetic injections.
    • Sodium bicarbonate in Onset buffers the anesthetic, reducing acidity and pain.
    • Onpharma’s Onset typically contains sodium bicarbonate and local anesthetic agents.

    Management of Complications

    • Persistent anesthesia or paresthesia can occur due to nerve trauma during administration.
    • Factors contributing to hyperesthesia include nerve irritation from local anesthesia.
    • Direct trauma from the needle can lead to complications in sensory or motor functions.
    • Manage persistent anesthesia or paresthesia in patients through reassurance, examination, and monitoring.
    • Following an examination, further steps may include referral to a specialist to evaluate nerve function.

    Local Anesthetic Considerations

    • Dentists must evaluate the risks and benefits of using 4% local anesthetic for mandibular block anesthesia.
    • Data suggests a lower incidence of paresthesia with lower concentrations of local anesthetics.
    • Trismus may be caused by muscle trauma or repeated injections in the area.
    • Management of trismus onset includes physical therapy and warm compresses.
    • Prevent trismus with proper injection techniques and avoiding unnecessary trauma.
    • For preventing hematoma, ensure accurate needle placement and avoid puncturing blood vessels.
    • Hematoma management may require cold compresses and observation.

    Infection and Emergency Management

    • Infection post-treatment can arise from contamination during administration or procedural breaches.
    • Recommended antibiotics for managing trismus due to infection include amoxicillin.
    • Prevent infection-related complications by maintaining aseptic techniques during local anesthesia.
    • Avoid intramuscular injections if respiratory distress is caused by local anesthetic-associated edema.

    Systemic Complications and Factors

    • The principles of systemic complications emphasize the importance of user technique in drug administration.
    • It suggests that toxicity is influenced by the user’s administration method and patient factors.
    • Idiosyncrasy refers to abnormal responses to drugs that are not easily explained by known pharmacological actions.
    • Toxicity can arise from high drug doses, environmental factors, or patient-specific responses.
    • Patient predispositions for local anesthetic overdose include existing medical conditions, age, or drug interactions.
    • Drug factors contributing to overdose involve concentration and route of administration.
    • Not all factors related to a patient are classified as predisposing for overdose; for example, absence of risk factors does not guarantee non-overdose.
