Question

For queen cat, balanced anesthesia involves administration of a sequence of the following drugs
A. Ketamine hydrochloride
B. Atropine Sulphate
C. Diazepam
D. Xylazine hydrochloride
Choose the correct answer from the options given below:

• A. B \(\rightarrow\) C \(\rightarrow\) D \(\rightarrow\) A
• B. C \(\rightarrow\) D \(\rightarrow\) B \(\rightarrow\) A
• C. D \(\rightarrow\) C \(\rightarrow\) B \(\rightarrow\) A
• D. B \(\rightarrow\) D \(\rightarrow\) C \(\rightarrow\) A

Hint:

Balanced Anesthesia Sequence: Premedication/Anticholinergic (Atropine, B) $\rightarrow$ Sedation (Xylazine, D) $\rightarrow$ Muscle Relaxation (Diazepam, C) $\rightarrow$ Anesthetic Induction (Ketamine, A).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Feline balanced anesthesia protocols: anticholinergic premedication $ ightarrow$ sedative-analgesic tranquilization $ ightarrow$ co-induction muscle relaxation $ ightarrow$ dissociative anesthetic induction.

Step 2: Detailed Explanation:
Standard chronological sequence for balanced feline surgical anesthesia:
1. Step 1 (B. Atropine Sulphate): Preanesthetic anticholinergic to prevent excessive salivation (hypersalivation) and bradycardia.
2. Step 2 (D. Xylazine Hydrochloride): Potent $\alpha_2$-agonist premedicant providing sedation, visceral analgesia, and chemical restraint.
3. Step 3 (C. Diazepam): Benzodiazepine muscle relaxant administered to counteract the muscle rigidity and catalepsy of ketamine.
4. Step 4 (A. Ketamine Hydrochloride): Dissociative general anesthetic for surgical induction and maintenance.
Sequence: B $\rightarrow$ D $\rightarrow$ C $\rightarrow$ A.

Step 3: Final Answer:
Hence, the sequence of balanced anesthesia is B $\rightarrow$ D $\rightarrow$ C $\rightarrow$ A, corresponding to option (D).
