AbstractThe use of regional anesthesia techniques for intra-operative anesthesia remains very controversial for patients scheduled to undergo spinal interventions. Spine surgery is still mostly performed under general anesthesia. This has to be explained by the patient's position required during surgery, the extent and duration of some procedures, the preference of the surgeon and/or anesthesiologist and a trend which becomes more and more prominent to abandon central nerve blocks in general. The presence of foreign material in the neighborhood of the surgical field may be a reason for surgeons to refuse such techniques. Nevertheless, during the last decade the available literature has increased progressively in support of regional anesthesia for these interventions. The present overview will focus on the feasibility of different regional techniques to be used intra-operatively. These techniques may also be of interest or even intended for prolonged postoperative analgesia and benefit even after a single bolus injection, continuous or intermittent administration. Although all techniques described offered favorable success rates, future research is mandatory to determine their superiority over general intra-operative anesthesia and conventional pain therapy.
