ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of early goal-directed therapy (EGDT) combined with Yiqi Fumai Lyophilized Powder (YFLP) on central venous-arterial carbon dioxide difference [P(cv-a)CO2] and central venous oxygen saturation (S(cv)O2) in patients with septic shock.</p><p><b>METHODS</b>Totally 50 patients with septic shock were assigned to the control group and the treatment group according to random digit table, 25 cases in each group. Patients in the control group received treatment according to EGDT principle. Those in the treatment group were intravenously injected with YFLP (5.2 g adding in 500 mL normal saline) additionally. Changes of P(cv-a)CO2, S(cv)O2, lactic acid, central venous pressure (CVP), mean arterial pressure (MAP), and APACHE II score were observed in the two groups before and after treatment. The 6-h success rate and 28-day mortality were also observed.</p><p><b>RESULTS</b>Compared with before treatment in the same group, lactic acid and APACHE II score decreased, levels of S(cv)O2, MAP, CVP increased in the two groups after treatment (P < 0.01). P(cv-a)CO2 decreased more obviously after treatment in the treatment group, and lower than that in the control group after treatment (P < 0. 05, P < 0. 01). The 6-h success rate was 48% (12/25) in the control group and 76% (19/25) in the treatment group (P < 0.05). The 28-day mortality was 36% (9/25) in the control group and 12% (3/25) in the treatment group (P < 0.05).</p><p><b>CONCLUSION</b>EGDT combined with YFLP could significantly elevate S(cv)O2, decrease P(cv-a)CO2 and mortality in patients with septic shock, and obviously improve the clinical effect.</p>
