Reactions to Misoprostol: A Case Report

Area of Science:

• Obstetrics and Gynecology
• Pharmacology
• Critical Care Medicine

Background:

• Misoprostol, a prostaglandin E1 analog, is widely used for labor induction and uterine evacuation.
• While generally considered safe with few side effects, its use in early pregnancy warrants careful consideration.
• Surgical methods for uterine evacuation are often preferred over non-surgical ones due to reduced complications and cost-effectiveness.

Observation:

• A 29-year-old woman at 11 weeks 6 days gestation received Misoprostol for a cystic hygroma.
• Shortly after administration, she developed cyanosis, tachycardia, and hypoxia, coinciding with a successful miscarriage.
• Despite initial management for suspected embolism, her condition rapidly deteriorated, leading to cardiorespiratory arrest and death.

Findings:

• The patient experienced severe hypoxia and anemia (hemoglobin 4 g/dL) following Misoprostol administration.
• Despite interventions including blood transfusion, she developed worsening tachycardia, hypoxia, and loss of consciousness.
• The case suggests a potential link between Misoprostol use and severe adverse events, including cardiorespiratory compromise.

Implications:

• This case underscores the potential for rare but life-threatening complications associated with Misoprostol, even in early pregnancy.
• Vigilant monitoring for adverse effects is crucial in patients receiving Misoprostol for any indication.
• Further research may be needed to elucidate the mechanisms behind severe Misoprostol-induced toxicity and to refine management protocols.
