Arterial oxygen saturation was measured by pulse oximetry in two groups of paediatric outpatients breathing room air during transport from the operating room to the postanaesthetic recovery room. In Group I (n = 60) readiness for transfer from OR to PARR was decided clinically. In Group II (n = 50) additional criteria of oxygen saturation (SaOe) greater than or equal to 98 per cent with end-tidal gas N2O less than or equal to 10 per cent and CO2 less than or equal to 45 mmHg were met. A higher incidence of desaturation (SaO2 less than or equal to 90 per cent) occurred in Group I (27 per cent) than in Group II (eight per cent) (P less than 0.05). More children under 2 yr desaturated in Group I (50 per cent) than Group II (17 per cent) (P greater than 0.05 less than 0.10). Twenty-two patients in each group had a recent history of upper respiratory tract infections. In these patients, desaturation was more marked in those in Group I (32 per cent) than in Group II (five per cent) (P less than 0.05). Within each group, the incidence of desaturation during transport was similar in patients with or without a recent URI.
在两组小儿门诊患者从手术室转运至麻醉后恢复室期间，通过脉搏血氧饱和度测定法测量其动脉血氧饱和度，这些患者呼吸的是室内空气。第一组（n = 60）从手术室转运至麻醉后恢复室的时机由临床决定。第二组（n = 50）满足额外标准，即氧饱和度（SaO₂）大于或等于98%，呼气末气体一氧化二氮小于或等于10%，二氧化碳小于或等于45 mmHg。第一组（27%）的低氧饱和度发生率（SaO₂小于或等于90%）高于第二组（8%）（P < 0.05）。第一组2岁以下儿童低氧饱和度发生率（50%）高于第二组（17%）（P在0.05至0.10之间）。每组中有22例患者近期有上呼吸道感染史。在这些患者中，第一组（32%）的低氧饱和度比第二组（5%）更明显（P < 0.05）。在每组中，近期有或无上呼吸道感染的患者在转运期间的低氧饱和度发生率相似。
