Intense local pain, swelling, ecchymoses, and oozing of the haemolysed blood from the site of snake bite, is most likely to occur with bite of which species of snake?
## **Core Concept**
The question tests knowledge of the clinical manifestations associated with snake bites, specifically the local effects caused by the venom of different snake species. Snake venom can cause a range of systemic and local effects, including pain, swelling, ecchymoses (bruising), and hemorrhage. The severity and nature of these effects can vary significantly depending on the snake species.
## **Why the Correct Answer is Right**
The correct answer, , is associated with intense local pain, swelling, ecchymoses, and oozing of haemolysed blood from the bite site. This is because the venom of contains cytotoxins and hemotoxins that cause local tissue destruction, leading to pain, swelling, and bruising. The hemotoxic effects also result in the oozing of haemolysed blood from the bite site. This profile of local effects is characteristic of the venom of .
## **Why Each Wrong Option is Incorrect**
- **Option A:** venom primarily causes neurotoxic effects such as muscle weakness, paralysis, and respiratory failure, rather than intense local tissue destruction and hemorrhage.
- **Option B:** venom also has neurotoxic effects similar to but might not cause as pronounced local tissue damage and hemolysis as .
- **Option D:** venom is known for its neurotoxic effects and might not produce the same level of local tissue destruction and hemolysis associated with .
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the local effects of a snake bite can give clues about the type of venom involved. For example, the presence of intense local pain, swelling, ecchymoses, and oozing of haemolysed blood is highly suggestive of a hemotoxic or cytotoxic venom, such as that of . This knowledge can guide initial management and help in predicting potential complications.
## **Correct Answer:** .
