We have assessed the influence of different surgical procedures on the
incidence, severity and duration of early postoperative hypoxaemia in 312
healthy infants and children undergoing elective palatoplasty. Group 1
patients underwent von Langenbeck palatoplasty (n = 149), group 2 patients
underwent push-back palatoplasty (n = 124) and group 3 patients underwent
combined push-back palatoplasty and superior pharyngeal flap surgery (n =
39). Arterial oxygen saturation (SpO2) was recorded while patients were
breathing air shortly after arrival in the recovery room (0 min), and at 5,
10, 15, 20, 30, 40, 50, 60, 120 and 180 min thereafter. Patients who
underwent more complex surgical techniques for palatoplasty had lower
postoperative SpO2 values, slower recovery of SpO2 and a higher incidence
of hypoxaemia during the early postoperative period. There were significant
differences in postoperative SpO2, values and the incidence of hypoxaemia.
The incidences of hypoxaemia and severe hypoxaemia were 27% and 1%,
respectively, in group 1, 37% and 12% in group 2, and 36% and 33% in group
3. Hypoxaemia occurred most commonly in the first 15 min in children after
von Langenbeck palatoplasty, in the first 40 min after push-back
palatoplasty and in the 120 min after combined push-back palatoplasty and
superior pharyngeal flap surgery. There were significant associations
between low SpO2 values, incidence of hypoxaemia on admission to the
recovery room and recovery scores.
