小儿腭裂修复手术后早期低氧血症的临床观察

The Clinical Observation of Early Postoperative Hypoxemia in Children Undergoing Cleft Palate Repair

目的与方法：用脉搏氧饱和度仪对比观察１２３例腭裂修复手术后小儿（腭裂组），９０例非腭裂修复手术小儿（对照组）的术后早期低氧血症发生率和血氧饱和度值（ＳｐＯ２）的恢复情况。结果：两组病人的术后早期低氧血症的发生率分别为３３．６％和１３．１％（Ｐ＜０．０１），严重低氧血症发生率则分别为１６．７％和４．４％（Ｐ＜０．０５）。低氧血症主要发生在３０ｍｉｎ以内，腭裂组的持续时间较对照组明显延长，术后ＳｐＯ２值的下降程度也明显低于对照组，恢复速度也相对较慢。结论：小儿腭裂手术后低氧血症的发生率较高，宜加强上呼吸道的管理。

Objective and Methods:Arterial oxygen saturation (SpO 2) was measured continuously with a pulse oximeter in 123 patients with cleft palate repair (group CP) and in 90 patients with other operations as control group in the recovery room. Results:The incidences of hypoxemia in two groups were 33 6% and 13 1%( P< 0 01),while those of severe hypoxemia were 16 2% and 4 4%( P< 0 05) respectively. Hypoxemia occurred most commonly within 30 minutes, but the duration of hypoxemia in group CP was longer than that in control group, and two patients in group CP lasted for more than two hours. As compared with control group, mean level of SpO 2 in group CP was lower and recovery speed was slower.Conclusions:The incidence of postoperative hypoxemia in CP children is quite high and the care of upper respiratory tract should be emphasized.
