Conduction anesthesia on the lower jaw
For dental treatment in the lower jaw, the procedure is basically the same as for the upper jaw. After making sure that previous treatments have been well tolerated, the lower alveolar nerve is numbed. This nerve originates from the mandibular nerve, the lower jaw nerve.
This nerve branch also belongs to the cranial nerve trigeminalis. In contrast to the upper jaw, a single injection is sufficient to anaesthetize the respective half of the lower jaw. The nerve first passes through the lower jaw bone and leaves it in the area of the molars.
At this point the anesthesia can be set. A control of success can only be done by feeling the pain at the beginning of the treatment. Here, too, the anesthesia lasts about two hours after the last injection.
In case of longer procedures a renewed dose of local anesthetic may be necessary. As long as the anaesthetic is effective, the muscle strength of the lip muscles is also weakened. This means that eating and drinking is not yet possible during this time, as the lower lip hangs down on the anaesthetized side.
Foot Block
With the foot block block block, all nerves supplying the foot are anaesthetised above the ankle joint. A total of five injections are necessary for this. After thorough disinfection, approximately three to five milliliters of xylocaine or ropivacaine are injected near the respective nerve. Local side effects may include hematoma or nerve damage. Under a foot block, various operations can be performed on the foot and toes.No foot block should be performed if there are infections in the ankle area or blood clotting disorders.
Must be clarified?
In principle, there is an obligation to inform the patient about every medical intervention. The person affected must be informed about the procedure, possible side effects and long-term consequences. An overview of alternative anaesthesia methods is also part of the education.
The patient must also have the opportunity to ask questions. An information sheet, as in the case of general anesthesia, with a signature is not absolutely necessary. A verbal explanation is sufficient. Depending on the risk and type of intervention, the information is given in varying degrees of detail.
