What sting extent on a limb classifies the injury as demanding immediate professional assessment for systemic absorption?
Answer
Covering more than half an arm or leg
The physical coverage of the sting area is a direct metric used to estimate the total volume of venom introduced into the victim's system. If the envenomation covers a significant proportion of a major limb, such as more than 50% of an arm or leg, the risk of substantial systemic absorption of the toxins increases dramatically. Even if the victim is not yet showing overt signs of respiratory distress or collapse, this extent of skin involvement signals a high venom load that necessitates prompt professional assessment to monitor for delayed systemic effects and manage the large wound area.
