Arterial blood gases and pH values were determined before and after performing abdominal hysterectomies in 32 women. Four to five liters of oxygen were given by nasal cannula to 15 patients, while 17 patients breathed only ambient air. Falls of arterial oxygen tension averaging 10 torrs were seen up to 30 minutes after surgery in the latter group, but no apparent hypoxemia occurred in the patients who received nasal oxygen. Postoperative mild hypoxemia present in patients undergoing pelvic surgery can be obviated by prophylactic administration of oxygen at low flows.
对32名女性进行腹部子宫切除术前和术后测定了动脉血气和pH值。15名患者通过鼻导管给予4至5升氧气，而17名患者仅呼吸周围空气。后一组患者在术后30分钟内动脉血氧分压平均下降10托，但接受鼻导管吸氧的患者未出现明显的低氧血症。盆腔手术患者术后出现的轻度低氧血症可通过预防性低流量给氧避免。
