Emergency Care for an Attack of Andersen-Tawil Syndrome

First Actions:

  • Respiratory and cardiac arrest are possible.
  • Call for Cardiac Monitoring/EKG
  • Draw electrolytes to determine serum K+
  • Provide 02 as thimble may not reflect 02 saturation due to cardiac dilitation
  • Lie patient in coma position to avoid aspiration.

Emergency Treatment of Thyrotoxic Hypokalemic Periodic Paralysis

 

A True Endocrine Emergency

Patients with Thyrotoxic Hypokalemic Periodic Paralysis typically present at the ER with an acute episode of paralysis involving the muscles of the extremities and limb girdles. The lower limbs are more frequently and severely involved than the upper. Weakness may be asymmetrical. Proximal strength is more severely impaired than distal strength. Respiratory and cardiac arrest are possible. Lie patient in coma position to avoid aspiration. 

Cardiac Signs

Emergency Treatment of the HyperKPP and/or PMC Attack

Hyperkalemic Periodic Paralysis and Paramyotonia Congenita can occur singly or in combination. 

While most attacks of Hyperkalemic Periodic Paralysis are brief and do not require emergency intervention, occasionally the serum potassium level will be high enough to cause cardiac distress, or muscle stiffness may interfere with respiration.  Attacks of weakness in Paramytonia Congenita are usually mild to moderate in severity, but myotonia of chest, diaphragm and throat muscles can be life-threatening under some circumstances.
