【摘要】 目的　研究常温下入肝血流阻断对兔肝组织氧分压 (Ptio2 )、二氧化碳分压 (Ptico2 )、酸碱度 (pH)和温度 (T)的影响及临床意义。方法　入肝血流阻断 15min后再灌注 ,通过组织气体分析仪持续测定兔肝组织Ptio2、Ptico2、pH 和T变化。结果　肝血流阻断后Ptio2下降至 7.6± 0 .1mmHg ;Ptio2值升至 16 3.± 2 7mmHg ;pH值降至 6 .7± 0 .1;T下降至 35 .6± 0 .7℃。再灌注 15min后 ,肝组织Ptio2、Ptio2、pH和T缓慢恢复。 结论　入肝血流阻断导致肝脏缺血 /再灌注损伤 ,肝组织代谢异常 ;肝组织内Ptio2、Ptio2、pH值和T观察是监测肝缺血 /再灌注损伤的一个重要方法。更多还原

【Abstract】 Objective To explore The change of hepatic tissue Po2,Pco2,pH and temperature (T) in ischemia reperfusion injure in rabbit liver.Methods Direct monitoring of Po2,Pco2,pH and hepatic temperature after clamping of the hepatic pedicle.Results During liver ischemia,Po2 decreased to 7.6±0.1 mmHg,Pco increased to 163.2±27 mmHg,pH decreased to 6.7±0.1 and T decreased to 35.6±0.7℃.After 15 min of reperfusion,the indexed may recover slowly.Conclusion Hepatic tissue Po2,Pco2,pH and T as a indicator of hepatic tissue matabolism are a parameter of early ischemia reperfusion injure in rabbit liver.更多还原
