Description
(1) 単一刺激法:1秒または10秒に1回、200μsの刺激電流を流して単一刺激を与える刺激方法である。
(2) TOF(Train of Four )法:0.5秒おきに4回連続する刺激を1群として、15秒毎に繰り返し行う刺激方法である。TOF法では、第1刺激と第4刺激の高さの比(TOF比)を%で表し、筋弛緩薬が効いていない時は100%となる。
(3) DBS(Double Burst Signal )法:20m秒おきに通常3個の刺激を1群として、0.75秒後にさらに1群発生させて、この2回のバースト刺激に対する反応の差を手で判定(触診法)する刺激方法である。
(4) PTC(Post Tetanic Count)法:強い筋弛緩状態で、単一刺激、4連刺激(TOF法)反応が完全に消失している場合に用いるもので、最初に1Hz の刺激を15回与え、それに対する反応が全く無いことが確認されると、テタヌス刺激を与え、3秒後、続けて1Hz の単一刺激を15回与えて、出現する反応の個数から次に4連刺激(TOF法)に対する反応が出現する時期を推測する刺激方法である。
(5) テタヌス刺激法:50Hz または100Hz の刺激を5秒間のみ与えるテタヌス刺激により、触診法で評価する刺激方法である。
前記電気刺激手段および筋反応検出測定手段により筋弛緩パラメータを得ると共に、前記筋弛緩パラメータとして、TOF比とTOFカウントのグラフを、モニタ画面上に時間軸を共通にしてそれぞれ異なる側に表示すると共に、前記TOFカウントのグラフ側の表示を反転表示することを特徴とする。
そこで、図1および図2において、本実施例の筋弛緩状態表示モニタ装置は、電気刺激検出測定装置10と、筋弛緩状態表示部30を備えたベッドサイドモニタ20とから構成されている。
