Which brachial plexus block is often called the 'spinal of the arm' because it reliably anesthetizes the entire arm?
Answer: Supraclavicular block
The supraclavicular block targets the brachial plexus trunks where they are most compact, providing reliable coverage for the entire arm.
In an erector spinae plane (ESP) block, local anesthetic is deposited between the erector spinae muscle and which bony landmark?
Answer: The transverse process
In the ESP block, local anesthetic is injected between the erector spinae muscle and the tip of the transverse process.
What is the primary reason ropivacaine is considered safer than racemic bupivacaine in regional anesthesia?
Answer: Less cardiac toxicity due to its pure S-enantiomer configuration
Ropivacaine is a pure S-enantiomer with reduced cardiac toxicity compared to racemic bupivacaine because of stereospecific sodium channel binding.
Which nerve roots form the sciatic nerve, making them the target of a popliteal sciatic nerve block for foot surgery?
Answer: L4-S3
The sciatic nerve is formed from L4-S3 roots; the popliteal sciatic block targets this nerve just above the popliteal fossa for foot and ankle procedures.
Which ultrasound safety technique is MOST effective at reducing the risk of intravascular injection during nerve blocks?
Answer: All of the above combined
Combining color Doppler imaging, pre-injection aspiration, and small-bore needles together provides the greatest reduction in intravascular injection risk.
What dermatomal level of epidural coverage is typically targeted for thoracic epidural analgesia during open abdominal surgery?
Answer: T6-L1
Thoracic epidurals for abdominal surgery target T6-L1 dermatomal coverage to encompass both the abdominal wall and visceral innervation.
