Summary

Severe hypokalemia from medical treatment caused patient paralysis. Muscle weakness resolved upon correcting the electrolyte imbalance, highlighting the importance of monitoring potassium levels during specific drug therapies.

Area of Science:

  • Nephrology
  • Clinical Medicine
  • Pharmacology

Background:

  • Iatrogenic hypokalemia, a potential complication of medical treatments, can lead to significant neuromuscular dysfunction.
  • Severe electrolyte disturbances require prompt recognition and management to prevent serious patient outcomes.

Purpose of the Study:

  • To present two cases of severe iatrogenic hypokalemia resulting in paresis/paralysis.
  • To discuss the mechanisms of hypokalemia induced by nephrotoxic drugs.
  • To review the treatment strategies for this electrolyte disturbance.

Main Methods:

  • Case report of two patients experiencing paresis/paralysis.
  • Analysis of clinical presentation and laboratory findings related to hypokalemia.
  • Review of literature concerning nephrotoxic drugs and hypokalemia.

Main Results:

  • Both patients presented with severe muscle weakness (paresis/paralysis) attributed to iatrogenic hypokalemia.
  • Neuromuscular function was restored following correction of the potassium levels.
  • The role of specific nephrotoxic agents in causing hypokalemia was considered.

Conclusions:

  • Iatrogenic hypokalemia can cause profound neuromuscular impairment.
  • Prompt identification and correction of electrolyte imbalances are crucial for patient recovery.
  • Understanding drug-induced hypokalemia mechanisms informs preventative and therapeutic approaches.
