Transportation to the recovery room after surgery can be associated with significant hypoxaemia, if a portable oxygen source and a pulse oximeter are not used. We analysed the condition of patients on admission to recovery after being transported from the operating room without additional oxygen and monitoring.
One hundred and thirty-one ASA II and III patients, aged 58.2 ± 15.96 years, were enrolled to the study. SaO2 readings immediately before transportation, and on arrival in recovery, were compared. Additionally, blood-gas analysis was performed 10 min after admission to the recovery room. The duration times of transport (T1), lack of monitoring (T2) and breathing with room air (T3) were measured.
The mean SaO2 before transportation was 96.9 ± 10.55%, and on arrival in the recovery room was 93.0% ± 6.35. The mean T values were: T1 - 90.0 ± 94.2 s, T2 - 152.6 ± 86.6 s, and T3 - 122.9 ± 86.8 s. Although the length of transport time was relatively short, mild hypoxaemia was observed in all patients, with the SaO2 returning to normal after 10 min on 40% oxygen. Blood gas analysis revealed mild respiratory acidosis in 73% of cases.
Additional oxygen via face mask and appropriate monitoring should be provided to all patients during transportation from the operating room to the recovery area.
如果不使用便携式氧气源和脉搏血氧仪，术后转运至恢复室可能会导致严重的低氧血症。我们分析了在未额外吸氧和监测的情况下从手术室转运至恢复室的患者的状况。
131例年龄为58.2±15.96岁的美国麻醉医师协会（ASA）分级为II级和III级的患者纳入本研究。比较转运前即刻及到达恢复室时的血氧饱和度（SaO2）读数。此外，在进入恢复室10分钟后进行血气分析。测量转运时间（T1）、无监测时间（T2）和呼吸室内空气时间（T3）。
转运前平均SaO2为96.9±10.55%，到达恢复室时为93.0%±6.35。平均T值分别为：T1 - 90.0±94.2秒，T2 - 152.6±86.6秒，T3 - 122.9±86.8秒。尽管转运时间相对较短，但所有患者均出现轻度低氧血症，吸入40%氧气10分钟后SaO2恢复正常。血气分析显示73%的病例存在轻度呼吸性酸中毒。
在从手术室转运至恢复区的过程中，应为所有患者提供经面罩吸氧及适当的监测。
