Abstract「要旨」トノメトリ法による動脈圧測定法(以下TBP法)の有用性を検討するため, 全身麻酔下の手術症例99人において, 観血法(以下IBP法)による測定法と10,157ポイントで同時測定を行い, 比較, 検討した. 両測定法間のbiasの平均値は, 収縮期血圧, 平均血圧, 拡張期血圧で, 各々-0.8, -2.4, -2.2mmHgといずれも小さかった. しかしながら, biasの標準偏差は, 各々±8.6, ±7.1, ±7.6mmHgとやや大きかった. TBP法はIBP法に代る血圧測定法というよりは, 校正に使用しているオシロメトリ法(以下OSC法)を更に発展させた非観血的な連続血圧測定法と位置ずけられる. 本法は, 1)血圧の急激な変化を素早く捉える, 2)患者に対して非観血的である, 3)手術室勤務者の感染の機会を少なくする, など多くの利点を有することから, 臨床麻酔で十分有用な測定法と考えられる.

AbstractWe examined accuracy, reliability and clinical acceptance of tonometric blood pressure measurement with intraarterial blood pressure measurement in anesthetized patients. The study population consisted of ninety-nine aduld patients (16-84 yr, ASA physical Status 1-2). A blood pressure cuff is placed on the upper arm and a 22G arterial cannula into the radial artery of the same side. An arterial tonometry sensor housing is placed on the contralateral radial artery. Data was sampled every 1〜3min throughout the anesthesia procedure. We compared two measurement values by “limits of agreement”. Limits of agreement (± 2SD) were ±17.2mmHg for systolic, ±14.2mmHg for mean and ±15.2mmHg for diastolic pressure in 10,157 paired points. Bias were negligible(-0.8 〜 -2.4mmHg). The agreement between TBP and IBP was limited. TBP cannot be expected as a replacement for IBP measurement. It should be regarded as a continuous oscillometric blood pressure measurement. Blood pressure measurement by tonometry is useful for patients with rapid alterations in blood pressure during anesthesia and surgery, and reduce the hazard related to intraarterial cannulation for both patients and operating room staffs.
