Lumbosacral paraspinal interfascial plane blocks for pain control after feminizing genital gender affirmation surgery.

Feminizing genital gender affirmation surgery (fgGAS) is increasing in prevalence in the USA. Management of postoperative pain following fgGAS is challenging. We report a series of patients where post-fgGAS pain was adequately controlled with paraspinal blocks. This is a case series of three patients who received bilateral lumbar and sacral erector spinae plane blocks after fgGAS. Block techniques, medications administered, opioid requirements and pain scores were reviewed. Erector spinae plane blocks provided adequate analgesia for 24-48 h following the block. Currently, there are two regional anesthetic techniques described for the treatment of postoperative pain after fgGAS. We describe two additional approaches as options for improved pain management in this patient population.
