Effect of salvia miltiorrhiza and Ligustrazine injection on the early myocardial damage of patients with severe burn / 中华烧伤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of salvia miltiorrhiza and ligustrazine injection on the early myocardial damage of severely burned patients.</p><p><b>METHODS</b>Twenty severely burned patients hospitalized from January 2010 to August 2011, with burn area equal to or more than 50% TBSA, were divided into two groups following hospitalization sequence, with odd number patients entering treatment group (T, n = 10) and even number patients entering control group (C, n = 10). Patients in C group were treated with routine methods, including fluid resuscitation based on the Third Military Medical University formula, anti-infection treatment, support treatment, and organ-protection treatment, etc. In addition to routine treatment methods, patients in T group received intravenous infusion of 250 mL glucose injection (50 g/L) containing 10 mL salvia miltiorrhiza and ligustrazine concoction, once a day, and continued for three days. Venous blood of patients was drawn at post burn hour (PBH) 12, 24, 48, and 72 to determine the plasma levels of cardiac troponin I (cTnI), creatine kinase isozyme MB (CK-MB), and atrial natriuretic peptide (ANP). Data were processed with t test.</p><p><b>RESULTS</b>At each time point, levels of cTnI, CK-MB, and ANP were lower in T group than in C group. Differences in contents of these parameters between two groups were statistically significant at most time points, with t values from 2.136 to 2.918, P < 0.05 or P < 0.01. Plasma levels of cTnI, CK-MB, and ANP in both groups peaked at PBH 12, which were respectively (28 ± 10) ng/mL, (76 ± 13) U/L, (430 ± 87) pg/mL in T group, and (38 ± 11) ng/mL, (87 ± 10) U/L, (453 ± 91) pg/mL in C group. From PBH 24 to 72, contents of above-mentioned parameters decreased gradually in both groups.</p><p><b>CONCLUSIONS</b>Early use of salvia miltiorrhiza and ligustrazine injection in severely burned patients can effectively reduce myocardial damage, thus protect the myocardium from injury.</p>
