This study will be scheduled between January - March 2021 at Selcuk University Department of Anesthesiology and Reanimation. A total of 70 patients from American Society of Anesthesiologists classification physical status of (ASA-PS) I-II, aged 6 months to 10 years, will be included in the study. Routine monitoring electrocardiogram (ECG), peripheral oxygen saturation (SpO2) and non-invasive blood pressure measurements will be made to patients into the operating room, and their basal levels will be recorded. All patients were transferred to the operating room without premedication. The patients will be assigned to two groups as in-plane technique (Group IP) and out of-plane technique (Group OP) according to the program randomization list. Routine anesthesia induction will be performed with 7-8% sevoflurane, 100% oxygen until the patient loses consciousness with a face mask. Then, vascular access will be established and propofol 2-3 mg for general anesthesia induction. kg 1 and fentanyl 1 ?g. kg-1 IV will be used. After the eyelash reflex disappears without any neuromuscular blocker medication, a suitable laryngeal mask airway device will be placed into supraglottic area, and the patient will be connected to the anesthesia device for ventilation. For the maintenance of anesthesia, 2% sevoflurane, nitrous oxide will be stopped, and 50% oxygen + air mixture will be used. For caudal epidural block, the patient will be turned to the lateral position. After the asepsis of the perianal region is achieved, the sterile 8-18 MHz lineer USG probe for Group OP will be placed transversely in the midline to obtain a transverse view in the sacral hiatus. For group IP, the probe will be rotated 90 degrees and applied with the in-plane technique. After it is observed that there is no blood or cerebrospinal fluid (CSF) with aspiration, local anesthetic (LA) injection will be performed under hemodynamic and ECG monitoring by calculating the dose as 0.5 mg.kg-1 (0.25% bupivacaine) and the volume as 0.5 ml.kg-1. A successful block will be defined as the absence of significant motor movements after surgical induction, after heart and respiratory rates do not increase up to 20% above basal levels. In addition, block application time, number of needle attempts, success at first entry, ease of visualization, LA spread will be recorded and evaluated as the success rate. In both groups, the surgical caudal block will begin 10 minutes after anesthesia. Intraoperative opioids or sedative drugs will not be used. Mean arterial pressure, heart rate and oxygen saturation of the patients will be recorded every 5 minutes. At the end of the surgery, patients will be extubated and followed up in the postoperative recovery unit. Postoperative pain 10 minutes, 30 minutes, 1st, 2nd, 3rd, 6th, 12th, 24th hours FLACC pain scale (Face Legs Activity Cry Consolabity = face , legs, activity, crying, consolation). Time to first analgesia requirement, total analgesic consumption and postoperative complications will be recorded. In the evaluations made to patients in both groups, if the FLACC scale is> 4, rescue analgesia will be administered intravenously with 15 mg.kg-1 paracetamol.
