摘要
全麻下经腹腔镜胆囊切除时腹内充入高压ＣＯ２气体，对患者通气及血流动力学有一定影响。５０例气道压力（Ｐａｗ）、动脉血气（ＡＢＧ）及心率、血压监测结果显示，充气后Ｐａｗ、ＰａＣＯ２及平均动脉压（ＭＡＰ）明显上升（Ｐ＜０．０１）。充气前５分钟预防性给予新型降压药压宁定（０．６ｍｇ／ｋｇ），能有效预防高压ＣＯ２气腹所致的血压上升（Ｐ＜０．０５），降低心肌氧耗并改善心排出。
Abstract:Laparoscopic cholecystectomy performed during general anaesthesia has negative effects on the patients'ventilation and hemodynamics because of intraabdominal hyperbaric CO_2. The pressure of airway (Paw), PaCO_2 and mean arterial pressure greatly increased(P<0.01) under the condition of hyperbaric pneumotoneum. Ebrantil given intravenously(0.6mg/kg) 5 minutes before inflation effectively prevented the elevation of blood pressure and decreased cardiac oxygen consumption and improved cardiac output.
