Background: In current era of high costing health care, the saddle block, a segmental block for lower four sacral spinal roots, is an essential method for day care surgery in anorectal surgical procedure. Aims: We designed our study to find out an easy way for specific saddle block through sacral dorsal foramens to make it suitable for day care and ambulatory anesthesia. Methods: We performed sacral saddle block through 2 nd dorsal foramen of sacrum injecting intrathecally 0.75 ml of 0.5% injection bupivacaine. Results: Posterior surface of lower limb including perineum, innervated by sacral component of spinal roots became painless. No motor block detected, only dilatation of anal sphincter was present. Conclusion: With limited involvement of sacral component of spinal roots and comfort to patient, sacral saddle block is highly suitable for anorectal surgical procedure without hemodynamic instability.
