intraosseous anesthesia delivery system

PROCEDURE: STEP 3 - Inserting the injection-needle and injecting

(a) Compress a cotton roll against the mucosa for a few seconds in order to absorb any slight gingival bleeding. This will also aid identification of the perforation.

(b) Holding the syringe in “pen-gripping” fashion, and remembering the angle at which the perforator was withdrawn from the bone, align and gently insert the injection-needle at approximately the same angle.

It is important to bring in the needle at the same angle at which the perforator was withdrawn.  The needle must be in line with the perforation to enable it to advance into the perforation. The injection–needle should be allowed to engage with the cortical bone with only very light pressure so as to avoid any tendency for the tip of the bevel to “dig” into the bone or to buckle, thereby hindering or preventing insertion of the needle.  If "digging" into the bone is still a problem, modified injection-needles with a flattened tip, referred to in the Components section, should be used.

(c) Slowly and gently inject the anesthetic. It will be found that with the Stabident System the syringe can be operated with a much lighter pressure than in the case of infiltration and block injections. Particularly in the case of an anesthetic containing epinephrine, it is essential to inject very slowly, and the patient should be in the supine position. Even so, injection of epinephrine- and levonordefrin-containing solutions will cause a transient heart rate increase (palpitations) in the majority of patients. This is not a problem for many or most patients, but it may be desirable to raise the point with the patient before proceeding with an epinephrine-containing anesthetic.

In the event that considerable force is required to inject, it must be assumed that the needle has not entered a suitable cancellous space, and an alternative site for injection must be chosen. In some cases the explanation is that the needle has become blocked.
