Which nerve roots are primarily targeted in an interscalene brachial plexus block for shoulder surgery?
Answer: C5-C6 nerve roots
The interscalene block targets C5-C6 nerve roots of the brachial plexus, providing excellent analgesia for shoulder procedures.
What is the maximum recommended dose of plain bupivacaine for peripheral nerve blocks?
Answer: 2 mg/kg
The maximum safe dose of bupivacaine is 2 mg/kg (up to 150 mg) to avoid systemic toxicity.
Which complication is most specifically associated with interscalene brachial plexus blocks?
Answer: Pneumothorax
Pneumothorax is a known complication of interscalene blocks due to the proximity of the lung apex to the injection site.
What is the first-line pharmacologic treatment for local anesthetic systemic toxicity (LAST)?
Answer: 20% lipid emulsion IV
20% lipid emulsion is the first-line treatment for LAST as it sequesters the lipid-soluble local anesthetic from cardiac tissue.
Which regional technique is preferred for analgesia after total knee arthroplasty because it preserves quadriceps strength?
Answer: Adductor canal block
The adductor canal block provides knee analgesia while preserving quadriceps motor strength, allowing earlier ambulation after TKA.
What does the standard epidural test dose typically contain to detect intravascular catheter placement?
Answer: 3 mL of 1.5% lidocaine with 1:200,000 epinephrine
The standard epidural test dose is 3 mL of 1.5% lidocaine with epinephrine to detect intravascular or intrathecal catheter placement.
