Background: Needle-free injection technology was developed to reduce the pain.
A comprehensive literature review was completed regarding needle-free injection technology and its applications, advantages over needle injections. This review describes needle-free injection technology involving the generation of force by using compressed gas in order to deliver anesthesia at very high speed through a nozzle. This review also describes injection methods that use a spring load jet injector. An overview of marketed products, recent trends and other needleless delivery systems is given. Needle-free injection technology is growing and has the potential to make the administration of anesthesia more efficient, safe and convenient
Methods: Thirty patients recorded using a facial pain scale-revised (FPS-R)
Results: The results indicated patients treated with needless injection system had less postoperative pain compared to patients treated with the conventional injection technique.
Conclusion: needless injection system procedure would always be more accepted with minimal postoperative pain by the children patients than the conventional one.
