“Based on lipophilic and hydrophilic properties, local anesthetics can interfere with ion channels such as sodium, potassium and calcium channels of the CNS and the heart leading to severe neuronal and cardiac (arrhythmia and contractile depression) adverse effects.”
“These local anesthetics caused, especially in the higher concentrations, hemolysis and increased the passive loss of potassium from the cell and leak of sodium into the cell.”
