The first recue analgesic was administered in the form of intravenous (IV) diclofenac 75 mg (diluted in 100 ml normal saline) 12 h after surgery when the patient reported a VAS of 5. Conclusions QL block is an effective, feasible, and safe option for providing analgesia for laparoscopic hernia repair in morbidly obese patients.
