ABSTRACT
BACKGROUND:
According to evidences from clinical practices and experiments, renal denervation achieved by removing both the afferent and sympathetic nerves has therapeutic impacts on poor renal function and hypertension in chronic kidney disease (CKD). Epidural anesthesia is presumed to function on the target spine segments with a complete sympathetic block. Based on this perspective, we hypothesized that epidural block with lidocaine could ameliorate renal injury in CKD rats. METHOD ANDRESULTS:
Male Sprague-Dawley rats weighing 250-300g were randomized into four groups control, CKD, CKDâ¯+â¯sham, and CKDâ¯+â¯epidural block with lidocaine groups. CKD was induced by resection of the lower and upper thirds of the left kidney followed by right nephrectomy one week later. Significant differences in renal function, sympathetic activation as well as renal fibrosis parameters were observed between CKD and control rats. These parameters corresponded with typical phenotypes of CKD rats. Epidural block with lidocaine improved renal function as well as renal fibrosis, and reversed the abnormalities of the renal function and cardiovascular parameters either fully or partially.CONCLUSION:
Epidural block with lidocaine confers renal protection, which is presumably mediated by decreasing sympathetic nerve activities in the renal region and other target organs in CKD.
