Abstract:
OBJECTIVE:To explore the effects of dobutamine on hemodynamics,tissue perfusion and respiratory function in patients with ARDS caused by septic shock. METHODS:Totally 26 patients with ARDS caused by septic shock were given Dobu-tamine hydrochloride injection 5 μg/(kg·min) by continuous pump for 20 min ,increasing by 5 μg/(kg·min) every 20 min to 15μg/(kg·min)for 6 h. Mean artery pressure(MAP)maintained at about 65 mmHg during continuous pump. Hemodynamic index-es [HR,MAP,cardiac output(CO),stroke volume(SV),total end diastolic volume(GEDV),intrathoracic blood volume index (ITBI),extravascular lung water index (ELWI),systemic vascular resistance index (SVRI)],tissue perfusion indexes (norepi-nephrine,urine volume,blood oxygen saturation,blood lactate)and ventilator parameter indexes(positive breathing pressure,min-ute ventilation volume,respiratory rate,peak inspiratory pressure and plateau pressure)of all patients were recorded before medica-tion,6,24,48 h after medication. RESULTS:There were no statistical significances in HR,MAP,GEDV,ITBI,blood oxygen saturation,blood lactate and respiratory rate before and after treatment (P>0.05). CO,SV,urine volume and minute ventilation volume of all patients 6,24,48 h after medication were significantly higher than before medication,and those indexes increased gradually as medication time. ELWI,SVRI,positive breathing pressure,peak inspiratory pressure and plateau pressure of all pa-tients after medication were significantly lower than before medication,and those indexes decreased gradually as medication time, with statistical significance(P<0.05). The levels of norepinephrine in all patients 24,48 h after medication were significantly low-er than before medication and 6 h after medication,with statistical significance(P<0.05);but there was no statistical significance between before medication and 6 h after medication(P>0.05). CONCLUSIONS:The early application of dobutamine ELWI,tis-sue perfusion and respiratory function in patients with ARDS caused by septic shock,and can keep hemodynamics stable.
