摘要 :目的 研究失血性休克患者术中氧代谢变化。 方法 10例外科失血性休克患者，置入Swan-Ganz导管，经液体复苏、循环氧代谢等治疗，了解治疗前后氧代谢的变化。 结果 肺动脉楔压(PAWP)从(0.6±0.2)kPa上升为(1.5±0.3)kPa，心脏指数(CI)从(2.0±0.3)L·min -1 ·m -2 上升为(4.5±0.8)L·min -1 ·m -2 (P<0.05)。氧代谢指标变化:氧供指数(DO 2 )由(260.4±67.0)ml·min -1 ·m -2 显著上升至(624.5±151.2)ml·min -1 ·m -2 (P<0.05)。氧耗指数(VO 2 )由(96.4±50.4)ml·min -1 ·m -2 上升为(150.9±43.0)ml·min -1 ·m -2 。 结论 通过术中氧代谢的监测，可改变我们对休克的传统评估方式，由以往的血流动力学调整转向氧代谢状态的调控。

    Abstract:Objective To investigate the intraoperative oxygen metabolism in patients with hemorrhagic shock.Methods Ten patients with hemorrhagic shockwere intubated with Swan-Ganz catheter and managed by administering liquid resuscitation and circulation and oxygen metabolism therapies.The parameters of oxygen metabolism were monitored.Results A series ofimprovements were noticed during the treatment.The Pulmonary arterial wedge pressure(PAWP)was increased from(0.6±0.2)kPa to(1.5±0.3)kPa;cardiac index(CI) ......
