長い時間16肝臓手術の齧歯動物モデルが確立されます。大動物モデルがある特定の利点を提供するにもかかわらず、: 人間のための標準的な手術機器を適用できる、手術手技、臨床使用に匹敵する、標準的な臨床的評価方法は、顕微鏡の装置は必要ありません実験に移ります。特別な実験室試験方法 (図 10) を必要とせず標準臨床血液検査が実施される?...

アルゴン プラズマ凝固法 (APC) は、三十年1,2以上の腹部手術で広く使われている楽器です。肝臓のシールによる主要な肝切除後の出血3を防ぐために表面をカット後、二次止血の達成のための標準的な技法です。プラズマ凝固法は、高周波電気焼灼器、イオン化されたガスのアークを介して電気エネルギーを提供の特殊な形式です。モノポーラ電熱止血を提供し、この非接触技術組織4に固執する電極を防止する利点があります。イオン化されたガスのビームは自動的に最低の電気抵抗の領域に送られます、抵抗上昇乾燥のため他の地域がまだ乾燥して離れになっています。これは凝固5,6の制服の限られた深さを生成します。凝固効果に影響する要因は活性化凝固装置とプローブから組織までの距離の電源設定の時間します。ヘリウムは別のキャリア ガスをプラズマ凝固7に使用することができます。最近の臨床研究に集中して成績ではなく、機能的な組織学的所見3,8,9,生体外で調査10 に焦点を当てた実験中または分離臓器11実験。
基になるプロトコルにより、豚の人間の標準的な装置を使用して臨床応用に近い大規模な動物モデルのプラズマ凝固法の効果に関する研究: 微小循環がレーザーのドップラー流量計による非侵襲的評価と分光光度計、この表示12,13の標準的な臨床ツールです。凝固過程での温度変化は、赤外線放射温度計とサーモグラフィ カメラで監視されます。凝固の深さは、組織学的ヘマトキシリン ・ エオシン組織サンプルの採取後のセクションを染色で測定されます。二次止血のための他の手段との比較、バースト圧力実験を行った。血圧を除外する explanted 器官で実施されますが前述のテクニック14とは対照的に関連した効果。プラズマ凝固のローカル影響の調査の説明に加えてブタモデルで標準的な血液検査を実施することもできます。
