In study, The investigators aimed to compare the intraoperative and postoperative analgesic efficacy of erector spinae plane block and rectus sheath block, which investigators routinely perform in surgeries with abdominal lover midline-upper midline incision, morphine consumption with patient-controlled analgesia, as well as patient and surgeon satisfaction.
Following ethics committee approval and written consent from the patients, the study was conducted on 60 patients aged between 18-75 years in American Society of Anesthesiologists (ASA) classes I-III, who were to undergo midline incisions. The demographic data of the patients were recorded and after routine monitoring and general anesthesia induction, they were divided into two groups as the ESPB group and RSB group. Hemodynamic data of all patients were recorded before induction, one minute after induction, and intraoperatively in 30-minute periods. Patient-controlled analgesia (PCA) prepared with morphine was administered to all patients. Patients' intraoperative hemodynamic data and administered opioid doses, postoperative visual analog scales (VAS) at rest and during coughing, time to first PCA dose, postoperative morphine consumption, need for rescue analgesics, duration time until first mobilization, opioid side effects, and patient and surgeon satisfaction were evaluated.

| Measure | Description | Time Frame |

| intraoperative hemodynamic data and administered opioid doses | Intraoperative hemodynamic values (peripheric oxigen saturation, mean arterial pressure, heart rate) of the patients and intraoperative opioid consumption (mg) were compared. | 150 minutes |
| postoperative visual analog scales at rest and during coughing | Postoperatively, both coughing and resting visual analog scale values (A rating between 0 and 10 was made. 0 no pain 10 severe pain) of the patients were recorded and compared between the groups. | 48 hours |
| time to first patient controlled analgesia (PCA) dose | The times when patients used the PCA device for the first time were recorded and compared between groups. | 48 hours |
| postoperative morphine consumption | Total morphine (mg) consumptions used with postoperative PCA were recorded and compared between groups. | 48 hours |
| need for rescue analgesics | Bolus-dose morphine administration was provided to patients with VAS ≥4 upon questioning in the clinic or in line with patients' complaints, and patients' VAS scores during the first use of PCA were recorded. It was planned for rescue analgesic to be administered in patients with VAS ≥4 despite PCA, firstly as 20 mg IV tenoxicam (Tilcotil®, Deva, Tekirdağ, Turkey), and secondly as 50 mg IV tramadol (Tramosel®, Haver, Istanbul, Turkey) if VAS was still ≥4 one hour after tenoxicam administration. | 48 hours |
| duration time until first mobilization | The times until the first mobilization of the patients were recorded and it was investigated whether there was a difference between the groups in terms of mobilization times. |

| opioid side effects | Side effects (nausea, vomiting and sedation) that may occur due to opioid use in patients were recorded. And it was investigated whether there was a difference between the groups. | 48 hours |
| patient and surgeon satisfaction | Patient and surgical team satisfaction were recorded using a 5-point Likert scale (A rating of 1 to 5 was requested. 1- not at all satisfied 2- somewhat satisfied 3- undecided 4- satisfied 5- very satisfied).The difference between the groups was investigated. | 48 hours |
