| Abstract | 「要旨」トノメトリ法応用による非観血的血圧測定法(TBP)を低血圧麻酔症例で観血的血圧測定法(IBP)と比較, 検討した. 全麻酔経過を通して収縮期血圧(r=0.91), 拡張期血圧(r=0.83)とも高い相関が得られた. 低血圧維持中も収縮期血圧(r=0.80), 拡張期血圧(r=0.71)とも高い相関が得られた. TBPとIBPの差は99%以上が15mmHg以内であった. また, 低血圧導入中, 低血圧維持中, 血圧回復中ともTBPはIBPに追従し, その波形はIBP波形と極めて類似していた. したがって, TBPは低血圧麻酔症例においてもIBPに代り得る有用なモニタリングであると考えられる. |

| Abstract | As preveously reported, we clarified the clinical usefullness of a noninvasive, continuous blood pressure monitor based on arterial tonometry (TBP) in patients during general anesthesia. The aim of the present study was to evaluate accuracy and reliability of this monitor in the special condition that blood pressure is artificially reduced by vasodilators during hypotensive anesthesia. There was a good correlation between TBP and invasive blood pressure (IBP) for both systolic (r=0.80) and diastolic (r=0.71) blood pressures even in the period of induced hypotension. Waveforms of TBP were similar to those of IBP, and changes in waveforms were quite identical during periods of decreasing blood pressure from baseline, of hypotention, and of recovering blood pressure to baseline. It is essential, during hypotensive anesthesia, to use a method of blood pressure monitoring which is required both continuous and sufficiently sensitive at low blood pressure, and continuous waveform monitoring. We contirmed that this TBP system clearly satisfied these needs. We then, conclude that TBP system can replace standard IBP system for monitoring blood pressure in patients during hypotensive anesthesia. |
