Risk factors in children having palatoplasty.

Palatoplasty carries a relatively high risk of hypoxaemia. We prospectively evaluated 23 children having elective surgery for cleft palate. Intubation was uneventful in 15 patients and the lowest pulse oximetry levels (mean: 93% (range: 100-57)) were less affected than those at extubation (mean: 83% (range: 100-21)) which was uneventful in 10. Establishing a free airway was associated with increased difficulties in patients with Pierre Robin sequence (n = 4). All children who had had a recent airway infection or a parent who smoked (n = 8) had some degree of difficulty in intubation, or extubation, or in both. Increased attention paid to these latter, avoidable, factors may potentially reduce the anaesthetic hazards in this group of patients, who are at increased risk.
