A new technique for sensory blockage of posterior branches of sacral nerves: Ultrasound guided sacral erector spinae plane block

[3] In lieu of this anatomical information we hypothesized that ESPB performed from the sacral level would provide effective analgesia for pilonidal sinus surgery. Following adequate muscle strength extubation was performed in the supine position and the patient was transferred to the recovery room (RR). [...]anatomical and radiological studies are required to better understand the mechanism of action for sacral ESPB.Acknowledgment The authors declare that they have no conflict of interest.Patient consent Written informed consent for the procedure and future publishing were obtained from patients.
