The most suitable agent for IV induction and maintenance in a day care surgery?
**Core Concept**
The question is testing the knowledge of an ideal agent for intravenous (IV) induction and maintenance in a day care surgery. This involves understanding the properties of anesthetic agents, their pharmacokinetics, and the specific requirements for day care surgery.
**Why the Correct Answer is Right**
The most suitable agent for IV induction and maintenance in day care surgery is Propofol. This is because Propofol has a rapid onset of action, short duration of action, and allows for quick recovery, which is essential for day care surgery. Propofol also has anti-emetic properties and can be easily titrated to achieve the desired level of anesthesia.
**Why Each Wrong Option is Incorrect**
**Option A:** Thiopentone is a barbiturate with a slower onset of action and longer duration of action compared to Propofol, making it less suitable for day care surgery.
**Option B:** Ketamine has a longer duration of action and can cause hallucinations and increased intracranial pressure, which are undesirable in day care surgery.
**Option C:** Midazolam is a benzodiazepine with a slower onset of action and longer duration of action compared to Propofol, making it less suitable for day care surgery.
**Clinical Pearl / High-Yield Fact**
Propofol is a water-soluble emulsion that can cause lipid accumulation in tissues, leading to changes in liver function tests. This should be monitored in patients receiving Propofol for an extended period.
**Correct Answer: C. Propofol.**
