如果一个间接的床边变量可以可靠地预测是否需要客观的仪器吞咽困难评估，可以节省时间和金钱而不影响患者护理。迄今为止，寻找一种可靠的、间接的主观愿望指标的工作尚未取得成功。然而，对愿望的间接客观标记的研究是诱人的。本研究的目的是研究纤维内镜吞咽评估（FEES(R)）在客观确认吸入状态的同时，动脉氧饱和度（SpO(2)）、心率和血压等生理参数的变化（如果有的话）。60名成年受试者被分为4组，每组15人。组1不需要补充氧气，不吸氧。第二组不需要补充氧气，表现为误吸。第三组需要补充氧气，不抽吸。第4组需要补充氧气并表现出吸入性。同时每隔1分钟收集一次SpO(2)、心率和血压的测量值，即在fee前的基线时间为5分钟；期间费用;5分钟后收费。结果显示，四组中任何一组的SpO(2)水平均无显著差异。在所有4组中，均观察到在费用期间和费用后持续5分钟的较高心率值的一致模式。四组患者在治疗期间血压值升高，治疗后血压值降低。结论是，不支持使用SpO(2)、心率或血压值的变化作为吸入的间接客观标记。
If an indirect bedside variable can reliably predict whether an objective instrumental dysphagia evaluation is needed, time and money can be saved without compromising patient care. To date, the search for a reliable indirect subjective marker of aspiration has not been successful. However, research on indirect objective markers of aspiration is alluring. The purpose of the present study was to investigate changes, if any, in the physiologic parameters of arterial oxygen saturation (SpO(2)), heart rate, and blood pressure during simultaneous objective confirmation of aspiration status with Fiberoptic Endoscopic Evaluation of Swallowing (FEES(R)). Sixty adult subjects were divided into 4 groups of 15. Group 1 did not require supplemental oxygen and did not aspirate. Group 2 did not require supplemental oxygen and exhibited aspiration. Group 3 required supplemental oxygen and did not aspirate. Group 4 required supplemental oxygen and exhibited aspiration. Simultaneous SpO(2), heart rate, and blood pressure measurements were collected at 1-min intervals, i.e., pre-FEES baseline for 5 min; during FEES; and post-FEES for 5 min. Results indicated no significant differences in SpO(2) levels based on aspiration status or oxygen requirements for any of the 4 groups. A consistent pattern of higher heart rate values during FEES and continuing for 5 min post-FEES was observed for all 4 groups. A consistent pattern of higher blood pressure values during FEES and then lower blood pressure Values post-FEES was observed for all 4 groups. It was concluded that the use of changes in SpO(2), heart rate, or blood pressure values as indirect objective markers of aspiration was not supported.
