TRIAL DESCRIPTION
Public title suprazygomatic versus infrazygomatic maxillary nerve block
Official scientific title Feasibility and Efficiency of ultrasound guided bilateral suprazygomatic versus infrazygomatic maxillary nerve block for cleft palate repair in children
Brief summary describing the background and objectives of the trial Cleft lip and/or palate are considered to be the most frequently encountered craniofacial malformation 1,2. Congenital cleft palate repair is ideally performed in the first year of life. The surgery is also considered to be an extremely painful procedure, with the most significant pain experienced in the early postoperative period 3,4. The surgical procedure can be complicated by airway obstruction and respiratory complications 5,6. Administration of opioids, often needed for intra- and postoperative analgesia, increases the risk of airway obstruction and promotes ventilatory control dysfunction 5,7. Regional anesthesia has a number of advantages and can provide postoperative analgesia in infants and neonates, without the risk of respiratory depression 8. Maxillary nerve block within the pterygopalatine fossa can provide sensory blockade of the hard and soft palate and, in this way, provide intra-operative and postoperative analgesia 9. The use of ultrasonographic guidance for regional anesthesia has recently been shown to be beneficial in children, mainly by limiting the puncture complications and block failures 10. The benefits of this technique are the visualization of key anatomic landmarks and confirmation of correct local anesthetic (LA) spread 11. The aim of this study is to compare the feasibility and efficiency of bilateral ultrasound guided suprazygomatic versus infrazygomatic maxillary nerve block for cleft palate repair in children.
