Abstract:
Objective • To investigate the effects of levosimendan on kidney injury in the rat model of cardiopulmonary resuscitation. Methods • Twentyfive healthy adult male SD rats were randomly divided into three groups, which were sham group (S group, n=5), levosimendan group (L group, n=10) and control group (C group, n=10). Cardiac arrest and cardiopulmonary resuscitation procedure were created in L group and C group by inducing ventricular fibrillation. L group was treated with levosimendan during and after resuscitation, while C group and S group were given equivalent volume of saline solution. S group was not induced into cardiac arrest and resuscitation. Serum interleukin-6 (IL-6), IL-10, tumor necrosis factor-α (TNF-α), creatinine (SCr), blood urea nitrogen (BUN) and cystatin-C (CysC) levels were compared between L group and C group at 1, 4 and 6 h after resuscitation.Three groups of rats were sacrificed, and the pathological changes of kidney tissues were observed at 6 h after resuscitation. Results • All rats were resuscitated successfully. No differences were found between the three groups about baseline data. After resuscitation, compared with S group, the levels of serum inflammatory cytokines and kidney function indicators increased dramatically (all P<0.05) in the other two groups. In resuscitation after 1, 4 and 6 h, the levels of IL-6 and TNF-α in L group were lower than those in C group, but IL-10 levels were higher in L group (P=0.000, P=0.002, P=0.036) than those in C group, and there were significant differences between the two groups (all P=0.000). In resuscitation after 1, 4 and 6 h, the levels of SCr (P=0.001, P=0.007, P=0.472), BUN (P=0.001, P=0.004, P=0.122) and CysC (P=0.493, P=0.001, P=0.175) were lower in L group than those in C group. Only 1 and 4 hours after resuscitation, the differences in the levels of SCr and BUN were significant, and only 4 hours after resuscitation, the difference in the level of CysC was significant between L group and C group. Both L and C group showed pathological characteristics of severe acute kidney injury, and the pathological injury scores of L group were alleviated compared with those of C group (all P=0.000). Conclusion • Levosimendan can improve kidney injury of cardiac arrest and cardiopulmonary resuscitation model rats.
