BACKGROUND: Snakebites in pregnancy can be life-threatening to both the mother and fetus as a result of inflammatory and toxic properties of the venom. Prompt medical treatment is critical to prevent adverse consequences.

CASE: A 26-year-old woman at 37 6/7 weeks of gestation was bitten by a rattlesnake on the right middle finger, resulting in severe pain radiating up to the upper arm and swelling involving the entire hand. A total of 18 vials of crotalidae polyvalent immune fab was administered over 11 hours. Three days after the incident, the patient delivered a healthy neonate vaginally and without complications. Both mother and newborn were well at 1-month follow-up.

CONCLUSION: Our case supports managing snakebites in pregnancy similar to managing cases in nonpregnant individuals, including using crotalidae polyvalent immune fab antivenom.

Managing snakebites in pregnancy is similar to managing cases in nonpregnant individuals, including using crotalidae polyvalent immune fab antivenom.
