Sepsis is a life-threatening organ dysfunction caused by dysregulation of a host's response to infections. Sepsis - one of the most common contributing factors to acute kidney injuries in critically ill patients - is caused by bacterial endotoxins that lead to excessive production of proinflammatory cytokines. This condition can be treated with few side-effects by using electroacupuncture (EA) to regulate the neuroendocrine immune system to control the production of these cytokines. A number of studies have proven that EA stimulates the vagus nerve to manage inflammatory responses through the cholinergic pathway, slowing sepsis. This study was conducted to investigate the effect of bilateral EA at ST 36 (Zusanli) on rats' renal function by measuring their levels of plasma urea and creatinine. Materials and Methods: This study was a randomized, double-blinded, laboratory experimental post-test, with both subjects and laboratory investigators blinded. Twenty-eight male Wistar rats were divided randomly into 4 groups of 7 rats each: (1) a control group; (2) a sepsis group; (3) an EA + group; and (4) a sham EA + group. EA and sham EA was applied once for 30 minutes before intraperitoneal administration of live Eschericia coli bacteria ATCC 25922. Six hours after administration of the bacteria the rats' plasma urea and creatinine levels were measured. Results: There was a statistically significant difference in the mean levels of urea (P < 0.001, 95% confidence interval (CI): 57.1-76.6) and creatinine (P = 0.005, 95% CI: 0.14-0.62) between the sepsis and control groups. Conclusions: These findings suggest that EA pretreatment at ST 36 attenuated the induced inflammatory bacteria response and mitigated acute kidney injury.
