Abstract
To investigate the effects of different fluid resuscitation on renal function and glycocalyx in septic shock rats. The septic shock SD rats (induced by lipopolysaccharide) were randomly divided into control group, normal saline resuscitation group, Lactate Ringer's solution resuscitation group and succinyl gelatin resuscitation group (n=6 each). The mean arterial pressure, heart rate, serum creatinine (Scr), urea nitrogen (BUN), renal blood flow, renal tissue pathology, serum interleukin-6, tumor necrosis factor α and glycocalyx were measured at baseline, the development of septic shock, 0 hour and 8 hours after resuscitation. When shock was established, the renal blood flow significantly decreased (P<0.05) and recovered to normal at 0 hour and 8 hours after resuscitation. Compared with normal saline group and succinyl gelatin group, the levels of Scr, BUN and glycocalyx components (heparan sulfate, syndecan-1) were significant lower in Lactate Ringer's solution group (P<0.05). The pathology of kidney tissue suggested that the microscopic ischemic damage with Lactate Ringer's solution were minor than the other two groups. Compared with normal saline and succinyl gelatin, Lactate Ringer's solution can reduce the damage of renal function and glycocalyx in septic shock rats.
