Which of the following induction agents is the most suiatable for day care surgery?
**Core Concept**
The question tests the ability to select an appropriate induction agent for day care surgery, considering factors such as rapid onset and recovery, minimal side effects, and low risk of residual effects. Day care surgery, also known as outpatient surgery or ambulatory surgery, requires anesthesia that allows for quick recovery and discharge.
**Why the Correct Answer is Right**
The correct answer is Propofol, which is a short-acting intravenous anesthetic agent that has a rapid onset and offset of action. It allows for quick recovery and is often used in day care surgery due to its favorable pharmacokinetic profile. Propofol has a low risk of residual effects, making it an ideal choice for patients who need to be discharged the same day.
**Why Each Wrong Option is Incorrect**
**Option A:** Thiopentone is a barbiturate-based induction agent, which has a longer duration of action compared to propofol and may cause residual effects, making it less suitable for day care surgery.
**Option B:** Ketamine is a dissociative anesthetic that can cause hallucinations and other psychoactive effects, which may not be ideal for day care surgery patients who need to be discharged in a stable state.
**Option C:** Etomidate is a short-acting induction agent, but it can cause adrenal suppression, which may not be desirable in day care surgery patients who may have underlying medical conditions.
**Clinical Pearl / High-Yield Fact**
Propofol is a lipophilic anesthetic agent, which allows it to rapidly cross the blood-brain barrier and induce anesthesia quickly. However, its lipophilicity also means that it can cause lipemia, which may affect laboratory tests.
**Correct Answer:** C. Propofol.
