Abstract:
BACKGROUND:This study evaluated the morphology of the rat liver when hyperbaric oxygen (HBO) was used at various stages of ischemia and reperfusion. METHODS:Thirty-two male Wistar rats, subjected to 30 minutes of hepatic ischemia and 30 minutes of reperfusion, were randomly assigned as follows: GIR (n = 8), control without HBO; GHBO/I (n = 8), in which HBO was applied only during ischemia; GHBO/R (n = 8), HBO only during reperfusion; and GHBO/IR (n = 8), HBO during both ischemia and reperfusion. Feasibility scores of hepatocytes were determined by assessing 8 items related to liver injury. RESULTS:The histologic injury score of the hepatic specimens was significantly lower in the GHBO/I group (79.0 ± 0.1) compared with the GIR group (135.0 ± 0.1). HBO was not effective when applied during reperfusion (GHBO/R, 151.3 ± 0.1) or during the ischemia plus reperfusion period (GHBO/IR, 131.0 ± 0.1). The sum was significantly higher (P < .05) in HBO-treated animals during the reperfusion period (ie, in the GHBO/R group compared with any of the other groups). CONCLUSIONS:A favorable effect was obtained when HBO was administered early during ischemia. HBO given in later periods of reperfusion was associated with a more severe sum index percentage of liver damage.
