Relationship between lactic acid clearance,SVRI and cardiac displacement monitoring and the therapeutic effect and prognosis of patients with septic shock
Objective To study the relationship of lactic acid clearance,systemic resistance index(SVRI)and cardiac displacement monitoring with treatment and prognosis of patients with septic shock.Meth-ods 161 patients with septic shock admitted to the Second Central Hospital of Baoding City from June 2020 to May 2022 were selected.The clinical therapeutic effect and prognosis of patients were counted.The related factors affecting the therapeutic effect and prognosis of patients with septic shock were analyzed.The relation-ship between lactic acid clearance,cardiac output(CO),stroke output(SV),SVRI and APACHEⅡ score was analyzed by Pearson correlation.Results Among 161 patients,90 cases were in the effective group and 71 cases were in the ineffective group,there were statistically significant in lactic acid,lactic acid clearance,CO,SV,systemic vascular resistance index(SVRI),and APACHEⅡ scores(P<0.05).Logistic regression analysis showed that lactic acid<198 mmol/L and lactic acid>245 mmol/L,lactic acid clearance<10%,CO<3 L/minm and CO>6 L/minm,SV<60 mL and SV>120 mL,SVRI<1 500 dyn/s/m-2/CM-5 and SVRI>2 000 dyn/s/m-2/cm-5 and APACHEⅡscores>24 were risk factors affecting the therapeutic effect of septic shock pa-tients(P<0.05).According to the statistics of the 28 d prognosis,95 cases had poor prognosis and 66 cases had good prognosis.There were significant differences in lactic acid,lactic acid clearance,CO,SV,SVRI and APACHEⅡ scores between the two groups(P<0.05).Logistic regression analysis showed that lactic ac-id<198 mmol/L and lactic acid>245 mmol/L,lactic acid clearance<10%,CO<3 L/minm and CO>6 L/minm,SV<60 mL and SV>120 mL,SVRI<1 500 dyn/s/m-2/cm-5 and SVRI>2 000 dyn/s/m-2/cm-5 and APACHEⅡ scores>24 were risk factors affecting the therapeutic effect of septic shock patients(P<0.05).Pearson correlation analysis showed that APACHEⅡ score was negatively correlated with lactic acid clear-ance,CO and SV,and positively correlated with lactic acid and SVRI(P<0.05).Conclusion Monitoring lactate clearance,SVRI level and cardiac displacement in patients with septic shock can provide effective refer-ence value for clinical evaluation of treatment effects and prognosis.
