Objective To establish the incidence of perioperative airway complications in a large series of pediatric patients undergoing palatoplasty and to identify which specific patient, procedural, and provider factors are associated with increased risk for perioperative adverse airway events (AAEs). Design Retrospective chart review. Setting Tertiary pediatric hospital. Patients Included were 300 patients who underwent primary cleft palate repair using the modified Furlow technique between 2008 and 2011. Patients were 2 years or younger at the time of the operation. Main Outcome Measure(s) Charts were reviewed for perioperative AAEs, which were defined as postoperative airway obstruction, oxyhemoglobin saturation ≤85% for ≥45 seconds, bronchospasm, laryngospasm, reintubation, and unplanned admission to the intensive care unit. Patient-specific factors (diagnosis of a craniofacial syndrome, Veau cleft type, preoperative pulmonary and airway history), procedural factors (operative time, anesthesia time, opioid dose, administration and reversal of neuromuscular blockers), and provider factors (experience, number of providers), were documented, and associations with AAEs were investigated. Results AAEs occurred in 23% of patients overall and were significantly more common in syndromic patients (P = .003), patients with jaw or tracheal anomalies (P = .001), and patients with a history of difficult airway (P = .001). Other significant factors included prior history of difficult intubation (P = .05), surgeon (P = .02) and anesthesiologist experience (P = .05), and operative time (P = .02). Conclusions Diagnosis of a craniofacial syndrome, a history of preoperative airway problems, and provider inexperience correlated with increased risk for airway complications after palatoplasty. Recognizing patients at risk for AAEs may permit improved preoperative planning to optimize surgical outcomes and minimize complications.
