title: Hypertonic saline-dextran resuscitation of acute canine bile-induced pancreatitis.
abstract: In this study, we examined the effects of hypertonic saline-dextran resuscitation (2,400 mOsm of sodium chloride, 6 percent dextran 70) on cardiopulmonary function and extravascular lung water in acute canine pancreatitis. Acute pancreatitis was induced in 21 dogs by injecting 0.5 ml/kg of autologous bile into the pancreatic duct. In 10 dogs, resuscitation was begun with a 4 ml/kg bolus of hypertonic saline-dextran solution; 11 dogs received no bolus. Lactated Ringer's solution was infused in all dogs to maintain mean arterial pressure and cardiac output at baseline values. Pulmonary hypertension accompanied by a significant increase in pulmonary vascular resistance and a decrease in lung blood flow occurred in those dogs resuscitated with lactated Ringer's solution alone. By contrast, dogs in the hypertonic saline-dextran group maintained pulmonary artery pressure and pulmonary vascular resistance at baseline values while nutritive blood flow to the lung decreased progressively. Our data suggest that hypertonic saline-dextran resuscitation effectively restores cardiac function while it significantly reduces fluid requirements, as well as the pulmonary hypertension and pulmonary edema that frequently accompany lactated Ringer's resuscitation of acute pancreatitis.
