探讨脉搏氧饱和度波形在急诊及创伤外科中的临床指导意义

Investigation of clinical guiding significance by pulse oxygen saturation waveform in department of emergency and traumatology

目的探讨在急诊及创伤外科中脉搏氧饱和度(Sp O_2)波形的临床指导意义及价值。方法对急诊及创伤外科收治的150例呼吸窘迫综合征患者进行回顾性分析,其中轻度低氧血症38例(轻度低氧血症组),中度低氧血症64例(中度低氧血症组),重度低氧血症48例(重度低氧血症组),根据Sp O_2波形的变化情况给予相关处理,分析比较三组的预后情况。结果轻度低氧血症组存活率为92.1%,中度低氧血症组存活率为65.6%,重度低氧血症组存活率为52.1%,重度低氧血症组的存活率低于轻度、中度低氧血症组(P<0.05)。结论在急诊及创伤外科中,对患者实施Sp O_2监测,能够为临床救治提供依据,具有显著临床指导意义。

Objective To investigate clinical guiding significance and value by pulse oxygen saturation（Sp O_2） waveform in department of emergency and traumatology. Methods A retrospective analysis was made on 150 patients with respiratory distress syndrome in department of emergency and traumatology. Among them, there were 38 cases with mild hyoxemia（mild hyoxemia group）, 64 cases with moderate hyoxemia（moderate hyoxemia group）, and 48 cases with severe hyoxemia（severe hyoxemia group）. All the groups received related treatment on the basis of Sp O_2 waveform changes, and their prognosis was compared. Results Survival rate was 92.1% in the mild hyoxemia group, 65.6% in the moderate hyoxemia group, and 52.1% in the severe hyoxemia group. The severe hyoxemia group had lower survival rate than the mild and moderate hyoxemia groups（P〈0.05）. Conclusion Implement of Sp O_2 monitoring in department of emergency and traumatology can provide evidence for clinical treatment, along with remarkably clinical guiding significance.
