Hypokalemic periodic paralysis (HPP) occurs in approximately 1 out of 100,000 people and is comparatively more common in asian men. HPP is to be considered in cases presenting with sudden onset of weakness. The paralytic attacks usually occur in the morning hours.
Management: The treatment involves correction of Hypokalemia. An important aspect about i.v. administration of potassium (k+) is that it should not be administered in glucose containing fluids. Mannitol is the better medium. The reason being, glucose can drive more K+ into the cells worsening the hypokalemia and weakness.
