ABSTRACT
Objective To explore application of pulse indicator continuous cardiac output(PICCO)in the treatment of septic shock during continuous renal replacement therapy (CRRT).Methods 34 patients with septic shock who underwent CRRT were randomly divided into the control group and the experimental group.Heart rate(HR),mean arterial pressure(MAP)and central venous pressure (CVP) were monitored in the control group.The experimental group were monitored by PICCO technology in addition to conventional monitoring,the hemodynamics parameters were collected such as end-diastolic volume index (GEDI),extravascular lung water index(EVLWI),and systemic vascular resistance index(SVRI),etc.Dehydration volume and supplementary volume were controlled by means of two group's hemodynamics parameters.The change of Acute Physiology And Chronic Health Evaluation-Ⅱ (APACHE Ⅱ),lactate (Lac),saturation of central venous oxygen(SevO2) and oxygenation index (PaO2/FiO2) were observed.Results After treatment of 72h,the decrease of APACHE Ⅱ and lactate in the experimental group was higher than those in the control group,the increase of ScvO2 in the experimental group was higher than those in the control group,the increase of PaO2/FiO2 in the experimental group was evidently higher than those in the control group.Conclusions During PICCO monitoring technique to guide CRRT therapy in patients with septic shock,the volume status of patients can be accurately controlled,organizational cycle can be improved,oxygenation of lung can be obviously improved,which contributes to treatment of septic shock.
