Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Erector spinae plane block group (ESP)<br>Single- shot ultrasound guided ESP block with 30 ml 0.25% bupivacain at the T10 vertebral level was performed preoperatively to patients in the ESP group (Group I). | Procedure: Erector Spinae Plane block ( Group I)<br>* ESP Block was performed preoperative to all patients in ESP block group. Patients in all groups were provided with intravenous patient- controlled analgesia device containing morphine for postoperative analgesia.<br>|
| non- blocked Group<br>consists of the patient group without any procedure | Procedure: non- blocked Group (GROUP II)<br>* This group was received no intervetion. Patients in all groups were provided with intravenous patient- controlled analgesia device containing morphine for postoperative analgesia.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| opioid consumption | In the recovery room, all patients were given a patient- controlled analgesia device containing morphine 0.5 mg/ml, set to deliver a 1mg bolus dose of morphine with an 10 min lockout time and 10 mg 4 h limit.Total morphine consumption during the 24 hours postoperative period will recorded at 5 times intervals ( 2, 4, 6, 12, 24 hours). | 24 hours after surgery | 
| Verbal analog Pain Scores on rest and movement | A Research assistant, blinded to the group allocation, interviewed patients and collected data at 5 times intervals ( 2, 4, 6, 12, 24, hours) in the 24 hours postoperatively. Patients were asked to rate their pain using verbal analog scale, where 0= no pain and 10= worst pain possible. | 24 hours after surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Demographic data | Age, BMI, ASA, Duration of surgery was recorded. | 24 hours after surgery | 
| incidences of adverse effects (like nausea and vomiting) | incidences of nausea and vomiting during the 24 hours postoperative period was recorded recorded at 5 times intervals ( 2, 4, 6, 12, 24 hours). | 24 hours after surgery |
