Post-dural puncture headache (PDPH) is treated definitively with what procedure?
Answer: Epidural blood patch
An epidural blood patch seals the dural puncture site with autologous blood, providing definitive treatment for PDPH.
Which nerve block is commonly used for postoperative analgesia after total knee arthroplasty to preserve quadriceps strength?
Answer: Adductor canal block
The adductor canal block provides knee analgesia while preserving quadriceps strength, enabling early mobilization after total knee arthroplasty.
What does the term 'continuous peripheral nerve block' refer to?
Answer: A perineural catheter delivering ongoing local anesthetic infusion
Continuous peripheral nerve blocks use a perineural catheter to deliver ongoing local anesthetic infusion for extended postoperative analgesia.
A patient develops tinnitus and metallic taste shortly after a peripheral nerve block injection. What should be suspected?
Answer: Local anesthetic systemic toxicity (LAST)
CNS prodromal symptoms of LAST include tinnitus, perioral numbness, and metallic taste, warning of impending systemic toxicity.
Which peripheral nerve block approach provides optimal coverage for shoulder surgery?
Answer: Interscalene brachial plexus block
The interscalene approach to the brachial plexus targets C5-C6-C7 roots, providing optimal coverage for shoulder and proximal arm surgery.
What is the purpose of adding epinephrine to a local anesthetic solution for nerve blocks?
Answer: Prolong duration and reduce systemic absorption via vasoconstriction
Epinephrine causes local vasoconstriction, reducing vascular absorption of the local anesthetic and prolonging block duration while decreasing systemic toxicity risk.
