Brief summary
In upper extremity surgeries, the brachial plexus block can be performed with different techniques at various levels depending on the proximal and distal level of the surgery. In this study, we aim to compare the different approaches of US guided costoclavicular technique. Lateral approache is more common for the costoclavicular block area. However, more needle maneuvers are needed especially in pediatric patients because of the coracoid process. Medial approach is recommended to overcome this problem. Thus demonstrate the safety of upper extremity blocks, which is an important part of multimodal analgesia, and to determine the most ideal technique in the pediatric patient group who will undergo upper extremity surgery. During the block application, the US imaging time, the difficulty level of needle imaging, the number of maneuvers required to reach the target image, whether additional maneuvers are required according to the local anesthetic distribution, the success of the block and the duration of the surgery, the total application time of the block and the duration of general anesthesia will be recorded. Mean arterial pressure and heart rate will be recorded at 30-minute intervals during the surgery. Standardized for pediatric patients The FLACC and Wong-Baker pain scores will be followed first 24 hours after surgery. The patient will be examined for motor and sensation, and analgesic doses will be recorded if used. Time to first pain identification, duration of sleep, patient and surgeon satisfaction will be recorded.
Detailed description
Peripheral nerve blocks; It is widely used in daily practice for anesthesia or as a part of multimodal analgesia in most surgical procedures. In upper extremity surgeries, the brachial plexus block can be performed with different techniques at various levels depending on the proximal and distal level of the surgery. In this study, the aim is to compare postoperative analgesic effects of these two ultrasound-guided techniques in pediatric patients. In this study, we aim to compare the different approaches of US guided costoclavicular technique. Lateral approache is more common for the costoclavicular block area. However, more needle maneuvers are needed especially in pediatric patients because of the coracoid process. Medial approach is recommended to overcome this problem. Thus demonstrate the safety of upper extremity blocks, which is an important part of multimodal analgesia, and to determine the most ideal technique in the pediatric patient group who will undergo upper extremity surgery. During the block application, the US imaging time, the difficulty level of needle imaging, the number of maneuvers required to reach the target image, whether additional maneuvers are required according to the local anesthetic distribution, the success of the block and the duration of the surgery, the total application time of the block and the duration of general anesthesia will be recorded. Mean arterial pressure and heart rate will be recorded at 30-minute intervals during the surgery. Standardized for pediatric patients The FLACC and Wong-Baker pain scores will be followed first 24 hours after surgery. The patient will be examined for motor and sensation, and analgesic doses will be recorded if used. Time to first pain identification, duration of sleep, patient and surgeon satisfaction will be recorded.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of needle maneuvers | Up to 15 minutes | Number of needle maneuvers according to local anesthetic distribution |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient number requiring rescue analgesics | Intraoperative 2-4 hours | If a ≥ 20% increase above preinduction values in MAP or HR was observed during the perioperative period, additional fentanyl dose (1 μg/kg) was applied intravenously. |
| Ideal USG guided brachial plexus cords visualization/needle pathway planning time | Up to 15 minutes | Practitioner's ideal image acquisition time |
| Needle tip and shaft imaging visualization | Up to 15 minutes | Likert scale: 1-5 |
| Requirement of additional needle maneuver due to insufficient local anesthetic distribution | Up to 15 minutes | Extra needle redirection to cover neural tissue |
| Face, Legs Activity, Cry, Consolability (FLACC) scores | Up to 24 hours | It corporates five categories of behavior, each scored on 0-2 point scale so that total score ranges from 0 to 10. Total scores of 0-3 is defined as mild or no pain, 4-7 as moderate, and 8-10 as severe pain. |
| Wong Baker FACES scale | Up to 24 hours | The scale shows a series of faces ranging from a happy face at 0, or no hurt, to a crying face at 10, which represents hurts like the worst pain imaginable |
| Motor blockade physical examination | Up to 24 hours | Each nerve scored on 0-2 point scale so that total score ranges from 0 to 8. Total scores of 0 point is defined as absent motor blockade (full movement); 1 point as partial blockade (able to free movement only) or 2 point as complete blockade (unable to move). (Separately for these four nerves; N. Medianus, N. ulnaris, N. radialis and N. musculocutaneous). |
| Total procedure difficulty according to the anesthesiologist | Up to 15 minutes | Likert Scale 1-5 (1:very hard 5:very easy) |
| Time to first pain | Up to 24 hours | Time to first analgesic |
| Patient number requiring additional analgesix | Up to 24 hours | Number of patients who require IV morphine (0.03 mg/kg) and paracetamol (15 mg/kg) |
| Sleeping duration | Up to 24 hours | Total hours of sleep first day |
| Complications/side effects | Up to 24 hours | Possible complications related to costoclavicular block (such as vascular puncture, hematoma, pneumothorax, diaphragma palsy...) |
| Family satisfaction | Up to 24 hours | Satisfaction score: 0: very unsatisfied 3: very satisfied |
| Surgeon satisfaction | Up to 24 hours | Satisfaction score: 0: very unsatisfied, 3: very satisfied |
| Sensorial blockade physical examination | Up to 24 hours | Each nerve scored on 0-2 point scale with pinprick test so that total score ranges from 0 to 8. Total scores of 0 point is defined as absent sensorial blockade (feels pain), 1 point as partial blockade (feels touch) or 2 point as complete blockade (no sense). (Separately for these four nerves; N. Medianus, N. ulnaris, N. radialis and N. musculocutaneous). |
