Local anesthesia by jet-injection device in minor dermatologic surgery.
BACKGROUND
Pain and needle-phobia can be a problem during the application of local anesthesia with syringe and needle.


OBJECTIVE
To evaluate a jet-injection device (without needle) to deliver local anesthesia.


METHODS
Two hundred and six minor dermatological procedures using a jet-injection device for administering local anesthesia into skin tissue were performed. We comment on the technical procedures, application, usefulness in relation to areas involved and the anatomical location of lesion, and total dosage of the anesthetic agent.


RESULTS
Total absence of pain during installation of anesthetic (N = 194; 94%). Good level of anesthesia in all patients. No local adverse effects.


CONCLUSIONS
The jet-injection device is easy to handle, it is harmless, it provides good levels of anesthesia, and the dosage of anesthetic agent is smaller than the dosage administered with conventional methods.
