The single operator anesthesia and/or drug delivery system disclosed herein incorporates a variable-output nerve stimulator and an aspirating syringe pump, both of which are controlled via a needle with controls for stimulation and aspiration/injection on the needle itself. Pre-set injection pressures can be monitored and regulated via the syringe pump. Further pressures can be objectively limited by the syringe pump. With this system, the single operator can with sterile conditions, incorporate ultrasound, nerve stimulation, and landmark palpation while simultaneously performing the block without any help from another caregiver/operator. This system can easily store or translate to the electronic medical record the specifics of the block, including for example pressures and stimulation level). The present invention further provides a means to remove all direct human elements of a nerve block and perform a nerve injection robotically or from a remote location.
