Quadratus lumborum block is a newly developed block with good performance in lower abdominal
surgery. In a cadaveric study, the spread of local anesthetic in the anterior approach of QL
block (QL3) was reported to cover nerve roots from T10 to L3. Thus, it was hypothesized that
this approach could be used in hip surgeries with minimal motor affection.

This study aims to compare QL3 block and suprainguinal Fascia Iliaca block in the duration of
postoperative analgesia, pain scores, motor power in quadriceps muscle, and side effects.

This is an interventional drug trail to evaluate the effect of different intrathecal opioids
on post-operative pain experiences in women who have undergone caesarean section surgery.
