Abstract:Objective To investigate the therapeutic effect of Shenfu injection on septic shock observed with the non-invasive cardiac output monitoring system (NICOM).Methods A total of 23 patients with septic shock were given with conventional therapy including antibiotic therapy, fluid infusion, and life support treatment and etc., and then were treated with Shenfu injection. Data of the non-invasive cardiac output measurement such as mean arterial pressure (MAP), cardiac index (CI), stroke volume variation (SVV), total peripheral resistance index (TPRI) were observed at 0 h and 12 h after treatment with Shenfu injection, and the level of lactic acid of blood (Lac) were observed at meantime.Results The level of MAP were 78.00 (68.50, 85.50) mmHg and 91.00 (85.00, 110.00) mmHg before and after treatment, and increased more significantly after therapy (P < 0.05); the CI were 3.20 (2.65, 3.60), 2.80 (2.50, 3.60) L/min/m2 before and after treatment, and there were no difference (P > 0.05); the level of SVV were 0.17 (0.12, 0.19) and 0.14 (0.11, 0.18) before and after treatment, and decreased more significantly after therapy (P < 0.05); and the level of TPRI were 2 078.00 (1 756.50, 2 320.50), 2 732.00 (2 186.00, 3 274.50) sec/cm2/m2 before and after treatment, and increased more significantly after treatment (P < 0.05). The level of lactic acid of blood were 2.60 (2.00, 3.35) and 1.70 (1.10, 2.20) mmol/L before and after treatment, and decreased more significantly after therapy (P < 0.05).Conclusion Shenfu injection can improve patient's state of hemodynamic in septic shock, and decrease the level of lactic acid of blood, with benefit for the treatment of patients with septic shock.
