Local anesthetics What is typically used - Bupivicain - Lidocaine Possible toxicity reactions - Anaphylaxis - Nerve damage - Skeletal muscle illness Rule of thumb - Max 2mg/kg Max per location - Cats - 0.1 ml - Medium dogs - 0.2 ml - Large dogs - 0.3 ml The foramens - Common places to put a block - Infraorbital - Maxillary rostral approach - Block PM 3 and all teeth mesial on the same side - Administer then apply pressure for 60s to ensure anesthetic stays in place - Tilt the nose up to help anesthetic block nerve - Caudal maxillary block - Affects several branches of the maxillary nerve - Blocks bone, teeth, soft tissue of upper jaw - Blocks bone of hard palate and soft tissue of corresponding side - Middle Metal Foramen - Rostral approach mandibular block - Blocks canine and incisors with bone and soft tissue of corresponding side - Inferior alveolar block - Extra oral and intraoral approach - Look for facial vascular notch - Teeth bone and soft tissue rostral to site of corresponding side Proper nerve block technique - 25 gauge and 1 ml syringe - Insert needle into desired area - Continually aspirate to ensure that local anesthetic is not being injected into vasculature - Put pressure over foramen to keep anesthetic in desired area
