Local anesthetic agents in dentistry. [18], The paravertebral block is versatile and can be used for various surgeries depending on the vertebral level it is done. Outline Local Complications Paresthesia Needle Breakage Hematoma Pain on Injection Facial Nerve Paralysis Infection Trismus Soft Tissue Injury Edema Ocular Complications 3/18/2017 2 3. The advantages of nerve blocks over general anesthesia include faster recovery, monitored anesthesia care vs. intubation with an airway tube, and much less postoperative pain. Nerve injury most often occurs from ischaemia, compression, direct neurotoxicity, needle laceration, and inflammation. [5] A higher lipid solubility makes the anesthetic more potent and have a longer duration of action; however, it also increases the toxicity of the drug. 2. When it is used on specific nerve pathways (nerve block), effects such as analgesia (loss of pain sensation) and paralysis (loss of muscle power) can be achieved. Interscalene brachial plexus blocks can be done before shoulder, arm, and elbow surgery. [6], Other complications include nerve injury which has an extremely low rate of 0.029-0.2%. However, specific complications (e.g., bleeding, infection) and contraindications (e.g., patient's refusal, allergies) to local anesthesia must be considered. About Wikipedia; Disclaimers; Search. Amylocaine. Epidural analgesia is often used to supplement general anesthesia (GA) for surgical procedures in patients of all ages with moderate-to severe comorbid disease; provide analgesia in the intraoperative, postoperative, peripartum, and end-of-life settings; and can be used as the primary anesthetic for surgeries from the me… Postoperative nausea and vomiting (PONV) are easier to prevent than treat, and multiple medications are available for patients who experience this issue.

In dentistry, the most commonly used local anesthetic is lidocaine (also called xylocaine or lignocaine), a modern replacement for procaine (also known as novocaine).

When it is used on specific nerve pathways (nerve block), effects such as analgesia (loss of pain sensation) and paralysis (loss of muscle power) can be achieved. Local anesthesia is used to numb a small area before minor procedures, including dental work and some skin treatments. Dexmedetomidine is not as widely used as epinephrine.
