Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: ESP( Erector Spinae Plane Block)<br>After induction parturient in the ESPB underwent bilateral ESPB at the level of T7 using a linear ultrasound (US) transducer. Intravenous fentanyl patient control device 24-hour fentanyl consumption will be recorded. | Procedure: Erector Spinae Plane Block<br>* The transducer was placed vertically 3cm lateral to the midline to visualize the muscles of the back, transverse process and the pleura in between the two transverse processes. After local infiltration of the needle insertion site with 2-3 ml of 2% lidocaine needle was inserted in cranial-caudal direction towards the transvers process using in plane technique until the needle cross all the muscles then interfascial injection of 20ml local anesthetics is done after ensuring negative aspiration, the procedure was repeated following the same steps on the other side of the back.<br>Procedure: Intravenous fentanyl patient control device<br>* 24-hour fentanyl consumption will be recorded.<br>|
| Active Comparator: control group<br>No regional anesthesia technique will be applied to the control group. Intravenous fentanyl patient control device 24-hour fentanyl consumption will be recorded. | Procedure: Intravenous fentanyl patient control device<br>* 24-hour fentanyl consumption will be recorded.<br>|
