Abstract: ［Abstract］Objective〖HTSS〗〓To evaluate the value of bedside ultrasound in patients with septic shock hemodynamic monitoring.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Eightysix cases shock patients in ICU were randomly divided into two groups:the control group using pulse indicating continuous cardiac output(PICCO) monitoring technology, monitoring indicators to guide patients to rehydration treatment, observation group using bedside ultrasound monitoring indicators to guide patients to rehydration treatment. The hemodynamics parameters measured by different measurement mode and the treatment effect as well as prognosis of different guiding methods were compared.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓There was no difference in HR, CVP, MAP, blood lactate levels, urine output, vasoactive drugs score, APACHEⅡscore after treatment 6 h between two groups(P＞005). There was no significant difference in CI, CO and SV between the 2 groups before and after treatment(P＞005). There was no difference in 6h infusion volume, the amounts of dobutamine and norepinephrine in two groups(P＞005). After ICU treatment, SV, CO and CI in the 2 groups were significantly higher than those before entering the ICU(P＜005), but there was no significant difference between the 2 groups(P＞005). There was no difference in mechanical ventilation, ICU stay time in two groups(P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Bedside ultrasound is convenient, noninvasive and realtime monitoring, which can be used for realtime monitoring and prediction of fluid resuscitation in septic shock patients, and has good application value.
