Arterial oxygen saturation during transportation of children from the operating room to the recovery room and in the recovery room was monitored in two groups of patients, one given 100% oxygen at the end of anesthesia, the other given a 50:50 mixture of oxygen and air. The oxygen-air group had a statistically significantly higher incidence of hypoxemic episodes. Preoxygenation with 100% oxygen before transfer from the operating room reduces the incidence of hypoxemia in children.
在两组患儿中监测了从手术室转运至恢复室期间以及在恢复室时的动脉血氧饱和度,一组在麻醉结束时给予100%氧气,另一组给予氧气和空气的50:50混合气体。氧气-空气组低氧血症发作的发生率在统计学上显著更高。在从手术室转运前用100%氧气进行预充氧可降低儿童低氧血症的发生率。
