Dental Block Basics



  Dental nerve blocks are an important tool for managing anesthetic safety and patient comfort especially in aged pets less tolerant of higher general anesthetic levels. Add 1 mg/kg each of lidocaine and bupivacaine to a syringe adding sterile water as described above for larger volumes. Inject 0.2 to 1.0 cc per site proportional to patient size at the appropriate sites as shown below. For a more caudal maxillary block place the needle further into the infraorbital canal, aspirate, then apply pressure with your finger over the infraorbital foramen while injecting the solution.
