Hysterectomy is one of the most commonly performed surgical procedures after cesarean section in many countries worldwide, especially among women of reproductive age. Postoperative pain is typically managed with oral and parenteral narcotics. Patient-controlled analgesia (PCA) is an effective pain management method that provides advantages such as faster pain relief, better dosage control, and elimination of the need for timer adjustments. Facilitating the recovery process and optimizing postoperative pain management are crucial components of perioperative care. To minimize systemic opioid requirements and opioid-related side effects, multimodal analgesia combining local anesthesia, peripheral, and non-opioid analgesics has become increasingly popular.
