The effects of transmuscular quadratus lumborum blocks on postoperative pain in arthroscopic hip surgery: a cohort analysis

Purpose The Transmuscular Quadratus Lumborum block (TQLB) is one of the newest blocks and has been used as an effective analgesic option for various surgeries. However, it is still uncertain whether the TQLB provides beneficial analgesic outcomes for hip arthroscopic surgeries. Therefore, we aimed to investigate effects of the preoperative TQLB on postoperative pain levels and perioperative opioid consumption in patients who underwent outpatient arthroscopic hip surgery.
