目的：观察血氧饱和度（SaO_2）和呼吸末二氧化碳分压（PETCO2）的变化。方法：选择22例湿肺肺叶切除患儿，随机分为单、双肺通气两组，分别测定麻醉前、手术后60min、吸痰时、拔管前的血氧饱和度呼吸末二氧化碳分压。结果：单肺通气（Ⅰ组）与双肺通气（Ⅱ组）SaO2比较，均高于Ⅰ组（P＜0.01），而PETCO2Ⅱ组均低于Ⅰ组（P＜0.01）。结论：在小儿湿肺手术中，应首先选用双肺通气，以维持围术期的正常生理呼吸功能。
Objective: To observe the changes of blood oxygen saturation (SaO_2) and end-tidal carbon dioxide partial pressure (PETCO2). Methods: Totally 22 children with wet lung lobectomy were selected and randomly divided into two groups: single lung ventilation and single lung ventilation. The partial pressure of end-tidal carbon dioxide was measured before anesthesia, 60 min after operation, and before sputum aspiration. Results: Compared with group Ⅰ (P <0.01), the single pulmonary ventilation (group Ⅰ) and double lung ventilation (group Ⅱ) SaO2 were lower than those of group Ⅰ (P <0.01), while those of PETCO2 Ⅱ group were lower than those of group Ⅰ (P0.01). Conclusion: In pediatric wet lung surgery, lung ventilation should be the first choice to maintain the normal physiological respiration during perioperative period.
