Myxedema coma, a severe form of hypothyroidism, requires prompt treatment with thyroid hormones and supportive care. Early identification of precipitating factors improves patient outcomes, leading to faster recovery.

Area of Science:

  • Endocrinology
  • Internal Medicine

Context:

  • Myxedema coma is a rare but life-threatening complication of untreated hypothyroidism.
  • This study reviews five cases managed between 1984 and 1992.

Purpose:

  • To describe the clinical presentation, management, and outcomes of myxedema coma patients.
  • To identify factors associated with successful treatment and recovery.

Summary:

  • Five patients (4 female, 1 male; aged 45-73) presented with myxedema coma, characterized by depressed consciousness, hypothermia, and bradycardia.
  • Three patients had undiagnosed hypothyroidism, and precipitating factors were identified in three cases.
  • Treatment involved thyroid hormone replacement (L-thyroxine/triiodothyronine), hydrocortisone, and supportive care.

Impact:

  • Prompt treatment, especially when precipitating factors are known, can lead to good outcomes.
  • Early normalization of body temperature and improved consciousness indicate successful management.
