Pregnant women with acetaminophen overdose should receive N-acetylcysteine treatment promptly. Early intervention significantly improves pregnancy outcomes, reducing risks of spontaneous abortion and fetal death.

Area of Science:

  • Toxicology
  • Obstetrics and Gynecology
  • Pharmacology

Background:

  • Acetaminophen overdose is a significant public health concern.
  • Pregnancy complicates overdose management due to potential fetal risks.
  • Limited data existed on N-acetylcysteine efficacy in pregnant patients.

Purpose of the Study:

  • To evaluate the impact of N-acetylcysteine treatment timing on pregnancy outcomes following acetaminophen overdose.
  • To determine the safety and efficacy of N-acetylcysteine in pregnant women.

Main Methods:

  • Retrospective analysis of 113 pregnant patients in a nationwide acetaminophen overdose study (1976-1985).
  • Focus on 60 cases with available pregnancy outcome data.
  • Correlation analysis between N-acetylcysteine administration time and outcomes like live birth, spontaneous abortion, and fetal death.

Main Results:

  • Outcomes varied significantly based on N-acetylcysteine treatment delay.
  • Early treatment (within 10 hours) resulted in a higher rate of normal infant deliveries.
  • Delayed treatment (10-24 hours) was associated with increased spontaneous abortions and fetal deaths, including one maternal death.

Conclusions:

  • Timely administration of N-acetylcysteine is crucial for pregnant women with acetaminophen overdose.
  • Early treatment improves pregnancy outcomes and reduces adverse events.
  • Pregnant patients with potentially toxic acetaminophen levels require prompt N-acetylcysteine intervention.
