FAQ
- Anaesthetic leaks out of the handpiece
- We know that when a tooth is extracted an injection should be used to numb various nerve structures. In the case, for example, of mandibular anaesthesia, it is expected that correct placement of the conduction anaesthesia should numb the N. mandibularis and the N. lingualis. How does that work with Anesto?
- Anaesthetic emerges from the deep tissue along the needle.
- How does adrenaline affect blood flow in the spongiosa?
- What effect does needle speed have?
- Should the injection pressure be memorized and what injection speed should be used?
- Anaesthetic cannot be injected because the needle is blocked. What needs to be done? What can the person performing the treatment do to avoid the needle becoming clogged?
- Can I also use standard needles? What is different about the intraosseous injection needles?
- Incomplete anaesthesia
- Do we need a new cannula for each patient?
- Do you have to use a new cannula for a new injection site?
