Direct Peritoneal Resuscitation Reduces Leukocyte Infiltration in the Kidney after Acute Brain Death
2018
Brain death is associated with significant inflammation within the kidneys, which may contribute to reduced graft survival. Direct peritoneal resuscitation (DPR) has been shown to reduce systemic inflammation after brain death. To determine its effects, brain dead rats were resuscitated with normal saline (targeted intravenous fluid, TIVF) to maintain a mean arterial pressure of 80 mmHg and DPR animals also received 30cc of intraperitoneal peritoneal dialysis solution. Rats were euthanized at zero, two, four, and six hours after brain death. Pro-inflammatory cytokines were measured using ELISA. Levels of IL-1β, TNF-α, and IL-6 in the kidney were significantly increased as early as two hours after brain death and significantly decreased with DPR. Levels of leukocyte adhesion molecules ICAM and VCAM increased after brain death and were decreased with DPR (ICAM 2.33{plus minus}0.14 v 0.42{plus minus}0.04 p=0.002, VCAM 82.6{plus minus}5.8 v 37.3{plus minus}1.9 p=0.002 at four hours) as were E-selectin and P-s...
