Abstract「要旨」指尖容積脈波の二次微分である加速度脈波は, 簡便な循環動態検査法のひとつとして広まりつつある. そこで術後ICU入室患者と脊椎麻酔患者の加速度脈波を測定し, 術中, 術後のモニターとしての有用性について検討した. 術後ICU患者において, 血圧, 加速度脈波(b/a, d/a), 心係数, 末梢血管抵抗を随時測定したところ, d/aと末梢血管抵抗のみ相関を認めた. また脊椎麻酔患者においては, 薬物注入前, 注入後15分, 30分の血圧, 加速度脈波(b/a, d/a)を測定した. 収縮期血圧は薬物注入前と比較し注入後15分, 30分に有意に低下した. b/aはそれぞれ有意に低下, d/aはそれぞれ有意に上昇した.

AbstractThe Acceleration Plethymogram (APG) in the second derivative wave of the plethymogram and provides a valuable noninvasive method for evaluating hemodynamics. The purpose of this study is to investigate the clinical usefulness of the APG for monitoring patients in the intensive care unit (ICU) and the operation room. In ICU patients, the following factors were recorded : blood pressure, cardiac index (CI), peripheral vascular resistance index (SVRI), and APG (the ratio of the height of the b-and a-wave, b/a, and d-and a-wave, d/a). The d/a correlated with SVRI. In the patients under spinal anaesthesia, recording of the APG (b/a, d/a) and blood pressure were made before anesthesia, and 15 and 30 minutes after anesthesia. Comparisons before and after anesthesia show that the b/a and systolic blood pressure decreased and the d/a increased significantly.
