目的分析重症急性胰腺炎(SAP)合并肺水肿患者的血流动力学变化。方法回顾性分析11例SAP在早期液体复苏过程中出现肺水肿患者的无创血流动力学监测资料。数据统计时点:以左心射血分数(EF)值≤0.40时作为T0,之前1h为T1,30min为T2,其后30min为T3,1h为T4。分析其动态变化特征。结果 SAP早期液体复苏治疗过程中出现肺水肿患者T0时反映心功能的指标比T1时明显降低,而射血前期时间(PEP)和收缩时间比(STR)明显增高;经减少液体负荷后1h(T4),上述指标均明显好转(P<0.05)。11例中,除1例心跳停止未能恢复死亡外,其余10例全部得到有效的救治。结论无创血流动力学监测有利于指导液体治疗和心功能评估。
Objective To analyze the hemodynamic changes in patients with severe acute pancreatitis (SAP) complicated with pulmonary edema. Methods The noninvasive hemodynamic monitoring data of 11 cases of SAP with pulmonary edema during early fluid resuscitation were retrospectively analyzed. Data statistics point: left ventricular ejection fraction (EF) value of ≤ 0.40 as T0, 1h before T1, 30min as T2, 30min after T3, 1h T4. Analysis of its dynamic characteristics. Results Compared with T1, the indices of heart function in patients with pulmonary edema at T0 in SAP during early fluid resuscitation were significantly lower than those at T1, while the pre-ejection duration (PEP) and contractile time ratio (STR) were significantly increased. After 1h T4), the above indicators were significantly improved (P <0.05). Among the 11 cases, all the 10 cases were effectively treated except one case whose cardiac arrest failed to recover. Conclusion Noninvasive hemodynamic monitoring is helpful to guide liquid therapy and cardiac function assessment.
