What are the three components of the general anaesthetic triad?

Analgesia, Disorientation, Excitement

Hypertension, Tachycardia, Delirium

Amnesia, Pain Relief, Muscle Relaxation (correct)

Loss of Eyelash Reflex, Slow Breathing, Hypersensitive Airway Reflexes

Why does autonomic sympathetic blockade during spinal anesthesia often lead to hypotension?

Because it reduces the patient's blood volume

Mainly when the block is at level T5 and above

As a result of decreased heart rate

Due to the effect on the central nervous system (correct)

What is the purpose of adding opioids to intrathecal anesthesia?

To provide prolonged postoperative analgesia (correct)

To reduce blood loss during surgery

To minimize the risk of hypotension

To speed up the onset of the blockade
