Ultrasound-guided continuous transmuscular quadratus lumborum block as a sole anesthetic technique for inguinal hernia repair in a high-risk patient

Quadratus lumborum (QL) block has been described as a postoperative analgesic technique by Blanco following superficial abdominal surgeries but has not been used as a sole anesthetic technique. This ipsilateral block with an indwelling catheter inserted for continuous QL block provided the pain-free course. It decreased opioid use both during intra and postoperative periods with a sensory block of T8–L1, thus avoiding complications related to general and neuraxial anesthesia in patients with low cardiac reserve. We report a high-risk case undergoing inguinal mesh hernioplasty under continuous QL block.
