Thyroid Storm





Learning Objectives





  • Recognize clinical presentation of thyrotoxicosis.



  • Describe management of thyrotoxicosis in pregnancy.



Thyroid storm and thyrotoxic heart failure are life-threatening hypermetabolic states in pregnancy. Thermoregulation, cardiovascular, nervous, and gastrointestinal systems can be affected, typically leading to multisystem failure ( Fig. 23.1 ). The key to management is to have a high index of suspicion.



Thyroid Storm Simulation


Materials Needed





  • Volunteer to act as standardized patient



Key Personnel





  • Attending obstetrician



  • Resident physician (if available in your institution)



  • Nurse



Sample Scenario


A 34-year-old G2P1 female at 32 weeks gestation presents with fever, vomiting, and “feeling like [her] heart is racing.” On exam, her pulse is 154. BP is 176/98. Temperature is 104.1. She appears agitated. You note marked exophthalmos. Fetal heart rate tracing shows baseline of 180 with minimal variability, no accelerations, and no decelerations.


– Discuss your differential diagnosis. What would be your initial work-up and management for this patient?


– As you are waiting for other lab results, her TSH results as <0.01. How do you continue to manage this patient?


Debriefing and Documentation





  • Suspected precipitating factor for thyroid storm



  • Medications received



  • Fluids received



  • Current vital signs



  • Fetal status




Precipitating Factors





  • Labor and delivery



  • Surgery



  • Trauma



  • Preeclampsia



  • Anemia



  • Sepsis



Diagnosis


Signs and symptoms of thyroid storm are frequently nonspecific. They include the following:




  • Hyperthermia



  • Nausea



  • Abdominal pain



  • Vomiting



  • Agitation



  • Diaphoresis



  • Dehydration



  • Tachycardia



  • Congestive heart failure



  • Arrhythmia



  • Confusion



  • Cardiovascular collapse



  • Malignant exophthalmos



The diagnosis is confirmed by low TSH and elevated T4 .
