Cardiac surgical patients often experience significant postoperative pain at the median sternotomy site.
In pediatric cardiac surgery, the recommended pre bypass dose of fentanyl to blunt the hemodynamic and metabolic stress response is 25-50 µg/kg Today lower doses are often used in order to achieve early extubation at such doses there is no guarantee that the stress response is completely abolished one way to overcome this problem is the use of the local anesthetic technique Regional anesthetic techniques reduce pain for up to 24 hours after cardiac surgery in children.
Pectointercostal fascial block was first described by de la Torre in patients undergoing breast surgery. This novel technique blocks the anterior cutaneous nerve which is a branch of the intercostal nerve that gives sensory supply to the skin.
The aim of the current study is to detect the effectiveness of pecto-intercostal fascial block in relieving postoperative pain in noncyanotic pediatric patients undergoing elective cardiac surgery the primary goal of this randomized study is to compare the postoperative pain score in the first postoperative 24 hours and to detect total dose of fentanyl requirements. The secondary goals are intraoperative hemodynamic stress response to surgical stimuli, analgesic consumption in the studied groups, cross-clamping and bypass time, time to extubation, intensive care length of stay, and postoperative complications.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Ultrasound-guided bilateral pecto-intercostal fascial block | Experimental | Patients will receive bilateral ultrasound-guided pecto-intercostal fascial block |
|
| Intravenous fentanyl | Placebo Comparator | Patients will receive only incremental doses of intravenous fentanyl |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Ultrasound-guided bilateral pecto-intercostal fascial block | Other | - PATIENT IN SUPINE POSITION, SKIN WILL BE DISINFECTED, A HIGH-FREQUENCY LINEAR PROBE WILL BE PLACED PARALLEL TO LONGITUDINAL AXIS OF STERNUM ON LATERAL BORDER AND SCANNED LATERALLY TO IDENTIFY 4TH AND 5TH COSTAL CARTILAGE. THE PECTORALIS MAJOR MUSCLE (PMM), INTERNAL INTERCOSTAL MUSCLE (IIM), TRANSVERSUS THORACIS MUSCLE (TTM), RIBS, AND PLEURA WILL BE IDENTIFIED. COLOR DOPPLER ULTRASONOGRAPHY WILL BE USED TO DETERMINE PERFORATING BRANCHES OF INTERNAL THORACIC ARTERY, WHICH TRAVEL ANTERIORLY THROUGH THE ANTERIOR CHEST WALL, PIERCING THE INTERCOSTAL MUSCLE AND PMM. A 22G NEEDLE WILL BE INSERTED IN PLANE WITH PROBE, IN CAUDAL-TO-CRANIAL DIRECTION UNTIL THE TIP IS POSITIONED IN INTER- FASCIAL PLANE BETWEEN THE PMM AND IIM. NORMAL SALINE WILL BE USED TO DETERMINE CORRECT PLACEMENT OF NEEDLE TIP IN INTER-FASCIAL PLANE, AS SHOWN BY SEPARATION OF FASCIAL LAYERS THEN LOCAL ANESTHETIC WILL BE INJECTED |
