Introduction

Anesthesia is a unique medical intervention which does not itself offer any particular medical benefit and instead enables the performance of other medical interventions. The best anesthetic is therefore one with the lowest risk to the patient that still achieves the end points required to complete the other intervention.

Endoscopic approach of spine surgery has almost entirely replaced the conventional approach of open spine surgery^[1] because of its advantages over the open surgery in terms of small incision, less tissue trauma, minimal blood loss, improved illumination and visibility, early return to activity and work, easier operative approach in obese patients, easier revision surgery because of less scar tissue in the access portal, lower complication rates, lower cost due to shorter operating times and shorter inpatient stay. Moreover the postoperative pain and the need for postoperative analgesics is meagre.
