  • Title: Effect of high-dose cimetidine on pulmonary extravascular water after acute smoke inhalation injury.
    Author: Stewart RJ, Yamaguchi KT, Santibanez AS, Matsubara G.
    Journal: J Burn Care Rehabil; 1986; 7(6):484-7. PubMed ID: 2828376.
    Abstract:
    An animal model utilizing gamma imaging was used to examine pulmonary edema of an inhalation injury model. Tests were conducted using radiolabeled tracers and a dual indicator dilution technique as well as gravimetric analysis of excised lungs to determine extravascular water formation. The effect of cimetidine (Tagamet, an H2 receptor antagonist) was investigated as a potential agent for reduction of pulmonary edema following inhalation injury. Control groups included no treatment; smoke only; fluids only; and smoke and fluids. These were compared with identical groups given the same treatments but with the addition of cimetidine (100-150 mg/kg body weight intravenously). Fluids administered were 5% body weight intravenous infusions of lactated Ringer's solution over two hours. Results show that pulmonary edema was evidenced in animals given an inhalation injury, and was markedly worsened by fluid resuscitation. Treatment with cimetidine at high doses, either before or after inhalation injury, did not protect the animals from formation of pulmonary edema.
