Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism, often presents with limb muscle paralysis, hypokalemia with elevated-free T3, T4, and low thyroid-stimulating hormone (TSH). We herein reported an unusual presentation of TPP with acute hypercapnic respiratory failure. A 28-year-old female had complaints of nausea and vomiting. Laboratory investigations showed a serum potassium level of 1.2 mEq/L. Thyroid function test revealed the TSH level of 0.021 μlU/mL and free T4 at 2.01 ng/dL. She suddenly suffered from dyspnea and drowsiness. Acute hypercapnic respiratory failure with CO 2 retention was found. Noninvasive ventilation was used. Rapid correction of hypokalemia and administration of propylthiouracil, propranolol, and 5% Lugol's solution were performed. After the normalization of potassium levels, the patient's respiratory pattern stabilized and noninvasive ventilator (NIV) use was discontinued. Respiratory failure is an unusual but lethal complication of TPP. Rapid correction of hypokalemia and temporarily NIV can successfully avoid endotracheal intubation for respiratory failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
