In this study, intravenous diazepam was a convenient, safe, and entirely adequate replacement of anesthesia for orthopaedia manipulations. It was administered in the hospital emergency room to both healthy and ill patients. A wide age range of patients was treated, and many very difficult reductions were accomplished. It is the author's firm opinion, however, that the physician using this technique should be capable of using emergency respiratory resuscitation equipment and that such equipment should be immediately available. Close attention should be paid to the recomended method of drug administration and the physician should be congnizant of potential complications.
