目的探讨联合脉搏血氧监测法对急性卒中误吸风险的评估价值。方法选择2005年4月至2007年7月首都医科大学附属北京世纪坛医院连续收治的急性脑卒中患者117例。急性脑卒中患者入院后24 h内分别按普通检查法(颅神经检查和洼田饮水试验)及联合脉搏血氧监测法(颅神经检查、洼田饮水试验联合同步的脉搏血氧监测法)评估患者的误吸风险。结果联合脉搏血氧监测法发现存在误吸风险的患者47例(40.2%),常规检查法为25例(21.4%),该方法评估误吸风险的比率明显高于普通检查法(P<0.01)。联合脉搏血氧监测法预测吸入性肺炎的敏感度是82.4%,普通检查法预测吸入性肺炎的敏感度是41.2%,两种方法的敏感度比较差异有统计学意义(P=0.001)。结论联合脉搏血氧监测法是一种评估误吸和吸入性肺炎风险的敏感方法。
Objective To explore the value of combined pulse oximetry in the risk of asymptomatic stroke. Methods A total of 117 consecutive acute stroke patients admitted to the Beijing Shijiatan Hospital, Capital Medical University from April 2005 to July 2007 were selected. Acute stroke patients were evaluated by routine examination (cranial nerve examination and Kubota drinking water test) and pulse oximetry (cranial nerve examination, Kubota drinking water test combined with pulse oximetry) within 24 h after admission Patients risk of aspiration. Results 47 patients (40.2%) were found to be at risk of aspiration by pulse oximetry, compared with 25 (21.4%) patients by routine examination. The risk of aspiration was significantly higher than that of routine examination (P <0.01) ). The sensitivity of pulse oximetry in predicting aspiration pneumonia was 82.4%. The sensitivity of common method in predicting aspiration pneumonia was 41.2%. The sensitivity of the two methods was statistically significant (P = 0.001). Conclusion Combined pulse oximetry is a sensitive method of assessing the risk of aspiration and aspiration pneumonia.
