Application of a versatile instrument for production of cutaneous anesthesia without needle penetration of the skin

A self-contained jet injector, the Syrijet Mk II, can be used for needle-less injection of anesthetic agents into the skin and subcutaneous tissues. Although designed for dental use, its compact size, simplicity, and versatility make it suited for many medical applications where a relatively small anesthetic field is desired, especially in children. It provides an anesthetic area for the introduction of standard hypodermic needles for more extensive tissue infiltration, or for definitive anesthesia for procedures such as marrow aspiration, biopsies, small lesion excision, and in certain field blocks such as digital or facial sensory. It is significantly free of side effects and complications.
