    Area of Science:

    • Toxicology
    • Arachnology
    • Emergency Medicine

    Background:

    • Latrodectus mactans (black widow spider) populations are increasingly found in urban environments.
    • Black widow spider venom contains a potent neurotoxin affecting the neuromuscular system.

    Purpose of the Study:

    • To describe the clinical presentation and management of Latrodectus mactans envenomation.
    • To identify effective therapeutic interventions and high-risk patient groups.

    Main Methods:

    • Clinical case review of Latrodectus mactans bites.
    • Analysis of venom's neurotoxic effects and patient outcomes.

    Main Results:

    • Envenomation causes significant pain and skeletal muscle spasms within 0.5 to 3 hours post-bite.

  • Severe cases may lead to respiratory compromise and coma.
  • First aid measures are ineffective; muscle relaxants and calcium gluconate show therapeutic utility.

    • Conclusions:

    • Prompt medical intervention is crucial for managing Latrodectus mactans bites.
    • Antivenom administration is vital for high-risk individuals, including pediatric and elderly patients, and those with pre-existing hypertension.
