Abstract

BACKGROUND
Today, there are computer controlled local anesthesia devices used clinically. The main principle is to control injection speed by computer aided system, and it relieves pain. However, there are few objective data considering this subject. In this literature review, we researched studies about computer controlled anesthetic delivery. We compared pain control effect of computer controlled to conventional local anesthetic syringe system.
METHODS
A bibliographic search in PubMed was performed and we reviewed original articles.
RESULTS
There were 18 publications that compared pain control effect of computer controlled to conventional system. There were 8 articles reported of children, similar pain control effect was found in 7 of them. One study showed superior pain control effect of computer controlled anesthetic delivery. For adults, 10 studies showed superior pain control effect in computer aided system.
CONCLUSIONS
Computer controlled anesthetic delivery has similar or superior pain control effect compared to conventional local anesthetic syringe system. For both children and adults, computer controlled anesthetic delivery could be clinically useful, still it may be more effective for adults.
