Ether is still used as a general anaesthetic in lndia, specially in peripheral hospitals because:
**Core Concept**
Ether, also known as diethyl ether, has been used as a general anesthetic for over a century. Its pharmacological properties include rapid induction of anesthesia and analgesia, but it also has several drawbacks, such as flammability and respiratory depression.
**Why the Correct Answer is Right**
The correct answer is D. It is cheap and can be administered without anaesthetic machine. Ether is indeed a cost-effective option for anesthesia, especially in peripheral hospitals with limited resources. Additionally, ether can be administered using a simple face mask or a hand-held inhaler, eliminating the need for a sophisticated anesthesia machine. This flexibility and affordability make ether a viable option in settings where more advanced equipment is not available.
**Why Each Wrong Option is Incorrect**
**Option A:** Ether is actually highly flammable and can easily ignite, making it a hazardous choice for anesthesia.
**Option B:** While ether has a characteristic sweet, pungent smell, it is not particularly pleasant and can cause respiratory irritation, especially at high concentrations.
**Option C:** Although ether does induce anesthesia rapidly, this is not the primary reason it is used in peripheral hospitals. Its rapid onset is just one of several factors that contribute to its utility in these settings.
**Clinical Pearl / High-Yield Fact**
Ether is an example of a "simple" anesthetic agent that can be used in resource-limited settings. However, its use requires careful attention to safety protocols and dosing to avoid complications.
**✓ Correct Answer: D. It is cheap and can be administered without anaesthetic machine.**
