简要总结
Cleft palate repair requires high doses of opioids for pain control postop. An alternative approach is placement of nerve blocks in the pterygopalatine fossa bilaterally, blocking the maxillary nerve & covering the entire midface. Application of bilateral suprazygomatic maxillary nerve blockade of the infraorbital nerve may provide effective analgesia for cleft lip repair, improving time to oral intake, pain control and time to hospital discharge.
详细描述
Cleft palate is a common congenital anomaly for which surgical repair is indicated during early childhood. The surgical repair of cleft palate is very painful, and generally requires high doses of opioids for adequate pain control, placing children at risk for post-operative respiratory depression and airway obstruction. An alternative approach to post-operative analgesia for cleft palate repair is the placement of nerve blocks in the pterygopalatine fossa bilaterally, blocking the maxillary nerve and covering the entire mid-face. This randomized, double-blinded study will investigate the utility of maxillary nerve blockade in controlling post-operative pain, decreasing opioid requirements, improving post-operative oral food and drink intake, and decreasing hospital length-of-stay after cleft palate repair.

盲法说明
During the block placement the surgical team will be asked to leave the operating room briefly to remain blinded to the group assignment of all patients as the surgical team will manage the subjects post-operative care and determine discharge readiness.
ICU nursing staff and parents will be informed of participation in the study but will not be informed as to group assignment to remain blinded.
