Recent sporadic reports have described the role pulse oximetry might play in monitoring trauma victims, and specifically in the assessment of patients with limb fractures where doubt exists concerning the adequacy of limb blood flow distal to the fracture after manipulation. The results of a prospective study to determine the changes in arterial oxygen saturation as shown by pulse oximetry before and after manipulation are presented. The results suggest that the pulse oximeter may be of use in confirming the presence or absence of adequate blood flow distal to a fracture, but that this information should be considered in the light of the clinical findings. The role of pulse oximetry in the early detection of a compartment syndrome complicating a closed limb fracture has yet to be determined.
近期的零星报告描述了脉搏血氧饱和度测定在监测创伤患者中可能发挥的作用，特别是在评估肢体骨折患者时，对于手法复位后骨折远端肢体血流是否充足存在疑问的情况。本文展示了一项前瞻性研究的结果，该研究旨在确定手法复位前后脉搏血氧饱和度测定所显示的动脉血氧饱和度变化。结果表明，脉搏血氧仪可能有助于确认骨折远端是否存在充足的血流，但该信息应结合临床检查结果来考虑。脉搏血氧饱和度测定在早期发现闭合性肢体骨折并发骨筋膜室综合征中的作用尚待确定。
