black widow spider bite (quick hits)

9 Jun

Red hourglass or triangles on ventral part in NA.

Abdominal pain is characteristic. Muscle pain, rigidity as well, nausea.

(Alpha-latrotoxin -> opening cation channels (including calcium channels) presynaptically -> increased release of neurotransmitters -> excess stimulation of motor endplates)

Circular pattern at bite site with possible central punctum.

Usually self resolving within 48 hrs.

Wound care, antiemetics, pain medication
