title: [Effects of various Ringer's solutions on acid-base balance in rats in hemorrhagic shock and with hepatic dysfunction].
abstract: We investigated the effects of bicarbonated Ringer's solution (BR) on arterial blood acid-base balance, and compared these with the effects of lactated Ringer's solution (LR) and acetated Ringer's solution (AR) in rats in hemorrhagic shock. Rats underwent 70% reduction of hepatic blood flow and blood shedding of 1.5% of body weight. Each solution was infused through the femoral vein at a rate of shed blood volume x 8.hr-1 for 30 min under urethane anaesthesia. After the blood shedding, arterial blood pH and HCO3-decreased but plasma lactate concentration increased. These parameters improved significantly in the BR group compared with those in the LR group. However, the LR group showed the lowest blood pH and the highest plasma lactate concentration among the groups. These results suggest that BR has superior effects on the arterial blood acid-base balance and glucose metabolism in rats in hemorrhagic shock and with hepatic dysfunction.
