对41例梗阻性黄疸(A组)和41例单纯胆囊结石(B组)血流动力学变化及其影响因素进行观察。结果表明A组TB、BTP显著增加,PVD、PVP显著高于B组,而SVR、MAP、PVBF显著低于B组(P<0.01)。相关分析显示A组TB与BTP、PVP、PVD呈显著正相关(P<0.01),TB、PVD、PVP、BTP与PVBF呈显著负相关(P<0.01)。逐步回归分析表明TB、BTP是影响SVR、MAP的主要指标,而SVR、MAP下降是影响PVBF的关键因素。
The hemodynamic changes and its influencing factors were observed in 41 cases of obstructive jaundice (group A) and 41 cases of simple gallbladder stones (group B). The results showed that TB and BTP in group A were significantly increased, PVD and PVP were significantly higher than those in group B, while SVR, MAP, and PVBF were significantly lower than those in group B (P<0.01). The correlation analysis showed that there was a significant positive correlation between TB and BTP, PVP, and PVD in group A (P<0.01). There was a significant negative correlation between TB, PVD, PVP, BTP, and PVBF (P<0.01). Stepwise regression analysis showed that TB and BTP were the main indicators affecting SVR and MAP, while the decline of SVR and MAP was a key factor affecting PVBF.
