Background and objectivesLimitations in manpower in health care facilities, both in civilian and military settings, can severely affect patient safety as well as overall outcomes. Regional anesthesia via neural blockade is an effective means of managing uncontrolled acute pain, which has been associated with cardiopulmonary, endocrine, immunologic, and hematologic derangement in addition to the development of potentially life-threatening coagulopathy. We have designed a remote-controlled injection device that may expedite the performance of regional nerve blocks in these situations.MethodsThis work examines how the device affects the ability of the operator to act independently with respect to various block component times by statistically comparing device-assisted blockade with usual or clinically relevant techniques. The classic or two-person technique was compared with the foot-controlled technique.ResultsThe results validated the hypothesis that the novel mechanism of performing a nerve block is not inferior to the classic technique with regard to the specified endpoints within our experimental design.ConclusionThis confirmation indicates that the use of this device may be feasible when the use of another technique could be cumbersome, or otherwise untenable.
