Venomous Snake and Spider Bites in Pregnancy

Area of Science:

• Toxicology
• Emergency Medicine
• Obstetrics

Background:

• Venomous snake and spider bites (envenomations) are uncommon in pregnant individuals in the U.S.
• Envenomations can pose significant risks to both maternal and fetal health.
• Healthcare providers in high-risk areas need specialized knowledge for managing these cases.

Purpose of the Study:

• To review common U.S. snake and spider envenomations.
• To examine the effects of envenomation on pregnant patients and fetuses.
• To outline management strategies for envenomation during pregnancy.

Main Methods:

• Literature review of original research, review articles, and guidelines.
• Focused on snake and spider envenomations in the United States.
• Analysis of maternal and fetal outcomes and treatment efficacy.

Main Results:

• Snake envenomations present higher maternal and fetal morbidity/mortality risks than spider envenomations.
• Limited data suggest snake and spider antivenoms are generally safe in pregnancy.
• Potential hypersensitivity reactions to antivenom require careful risk-benefit assessment.

Conclusions:

• Antivenom therapy for symptomatic pregnant patients is likely safe with appropriate monitoring.
• Understanding indications for antivenom and care escalation is crucial for optimal outcomes.
• Further research is necessary to fully elucidate the effects of envenomation and antivenom on pregnancy.
