目的:通过对不同疾病的危重患者脉搏指示连续心输出量(PiCCO)监测参数的比较,探讨左室每搏做功指数(LVSWI)在PiCCO监测中的意义。方法:对行PiCCO监测的危重患者资料进行回顾性分析,收集行PiCCO监测基线(0h)及24h的监测数值,选取感染性休克患者(感染性休克组)以及神经外科重症患者(神外重症组)进行比较。结果:感染性休克组心排血指数(CI)及LVSWI在0h均低于神外重症组患者(P<0.05),血管外肺水指数(EVLWI)高于神外重症组患者(P<0.05);感染性休克组24hLVSWI较0h显著升高(P<0.01),但与神外重症组比较仍低下(P<0.01)。结论:LVSWI在不同的危重患者人群中存在差异;与神经外科重症患者比较,感染性休克患者LVSWI明显低下,提示存在脓毒症心功能障碍。
OBJECTIVE: To compare the parameters of PiCCO monitoring in critically ill patients with different diseases and explore the significance of LVSWI in monitoring PiCCO. Methods: The data of critically ill patients undergoing PiCCO monitoring were retrospectively analyzed. The monitoring data of PiCCO monitoring baseline (0h) and 24h were collected. Septic shock patients (septic shock group) and severe neurosurgery patients )Compare. Results: The index of cardiac output (CI) and LVSWI in septic shock group were lower than those in extrahepatic severe group (P <0.05) and the extravascular lung water index (EVLWI) ); 24hLVSWI in septic shock group was significantly higher than that in 0h (P <0.01), but still lower than that in severe extrahepatic group (P <0.01). CONCLUSIONS: LVSWI varies in different critically ill patient populations; LVSWI is significantly lower in septic shock patients than in neurosurgical critically ill patients, suggesting the presence of sepsis-induced cardiac dysfunction.
