The purpose of this study was to investigate the relationship between lower esophageal contractility (LEC), clinical signs, EEG, and enflurane dosage as expressed by minimum alveolar concentration (MAC). Significant (P less than 0.01) correlations were observed between MAC and LEC, MAC and EEG. No correlations were observed between MAC and BP. HR versus LEC, BP versus LEC, and EEG versus LEC correlated only partially. The measurement of LEC is a promising new technique for assessing depth of anesthesia by inhaled anesthetic agents.
本研究的目的是探讨食管下段收缩性（LEC）、临床体征、脑电图（EEG）与以最低肺泡浓度（MAC）表示的安氟醚剂量之间的关系。观察到MAC与LEC、MAC与EEG之间存在显著相关性（P小于0.01）。未观察到MAC与血压（BP）之间存在相关性。心率（HR）与LEC、BP与LEC以及EEG与LEC之间仅存在部分相关性。LEC的测量是一种通过吸入麻醉剂评估麻醉深度的有前景的新技术。
