Five patients with a side-to-side arteriovenous fistula complaining of pain, numbness, and cold sensation were evaluated by pulse oximetry. Low SaO2 was noticed in all five. Closure of a major proximal venous collateral vessel eliminated the steal and resulted in SaO2 correction and was followed by clinical amelioration. Pulse oximetry proved to be a helpful adjunct in the evaluation of the painful hand after creation of an arteriovenous fistula. By applying the pulse oximeter to the patient's affected limb, we were able to determine whether the pain was a result of ischemia and if the correction of the steal improved oxygenation.
对5例患有侧侧动静脉瘘并伴有疼痛、麻木和冷感的患者进行了脉搏血氧饱和度测定评估。所有5例患者均发现血氧饱和度低。结扎一条主要的近端静脉侧支血管消除了盗血现象，使血氧饱和度得到纠正，并随后出现临床症状改善。脉搏血氧饱和度测定被证明是评估动静脉瘘形成后手部疼痛的有用辅助手段。通过将脉搏血氧仪应用于患者的患侧肢体，我们能够确定疼痛是否由缺血引起，以及盗血现象的纠正是否改善了氧合。
