Intravenous Lipid Emulsion Increased Muscles Power and Survival Time of Phenobarbital in Intoxicated Rats

Abstract

Background: Phenobarbital (PHB) is an anticonvulsant drug that poisoning with it leads to stupor or coma and in higher doses may induce severe respiratory depression and cardiovascular collapse. Intravenous Lipid Emulsion (ILE) has been used to treat drug toxicity and for parenteral nutrition.<br />Methods: Ten male rats that had been intoxicated by 100 mg/kg of PHB were treated intravenously by 18.6 ml/kg of ILE20 or similar dose of normal saline. Subject rats were checked before PHB injection (zero time), 0.5 hr before ILE20% (or normal saline infusion) and 1, 3, and 6 hr after PHB toxic injections. On each check point, we tested the blood pressure, muscular power score and mortality rate.<br />Results: There were no significant differences between blood pressures of two groups at all. ILE was able to increase rats' muscular power scores at the 3rd and 6th hours check points (p=0.007 and 0.0371, respectively). ILE also increased the survival period of intoxicated rats; however it did not change the mortality rate. <br />Conclusion: ILE was able to reverse the muscles power reduction and could improve the survival period among intoxicated rats.
