In thyrotoxic periodic paralysis, hypokalemia and hypophosphatemia are highly prevalent, and potassium administration carries a significant risk of rebound hyperkalemia.
Hypokalemia, hypophosphatemia, and mild hypomagnesemia are characteristic features of TPP. Hypokalemia occurred in 100% and hypophosphatemia in 80% of the episodes in our study. Rebound hyperkalemia is a potential hazard of potassium administration and occurred in 42% of 24 episodes.
Manoukian et al. (Mon,) studied this question.
