Read the first 6 ABA Regional & Neuraxial Anesthesia flashcards as text

  1. Transient neurologic symptoms (TNS) are MOST commonly associated with which local anesthetic used for spinal anesthesia?

    Answer: Lidocaine

    Lidocaine spinal anesthesia is associated with TNS — buttock and lower extremity pain lasting 24-72 hours without neurologic deficit — at a much higher rate than other agents.

  2. The ultrasound-guided TAP (transversus abdominis plane) block targets the nerve plexus located between which two muscle layers?

    Answer: Internal oblique and transversus abdominis muscles

    The TAP block deposits local anesthetic in the fascial plane between the internal oblique and transversus abdominis muscles, blocking T10-L1 abdominal wall afferents.

  3. Cauda equina syndrome after neuraxial anesthesia is MOST associated with:

    Answer: Continuous spinal via microcatheter with maldistribution of hyperbaric lidocaine

    Cauda equina syndrome has been linked to continuous spinal catheters where pooling of concentrated lidocaine around sacral roots causes permanent neurotoxicity.

  4. During epidural catheter placement, loss of resistance technique confirms entry into the epidural space by demonstrating:

    Answer: Sudden loss of resistance to injection of air or saline

    The epidural space is a potential space with negative pressure; as the needle enters from the high-resistance ligamentum flavum, resistance to injection suddenly disappears.

  5. Which peripheral nerve block is used for post-operative analgesia after total knee arthroplasty while PRESERVING quadriceps strength for early ambulation?

    Answer: Adductor canal block

    The adductor canal block targets the saphenous nerve and medial retinacular branches predominantly, providing knee analgesia with minimal motor blockade compared to femoral nerve block.

  6. A patient scheduled for shoulder surgery under interscalene block has a preoperative FEV1 of 1.2 L (55% predicted). The PRIMARY concern with this block is:

    Answer: Ipsilateral phrenic nerve palsy causing 25% reduction in pulmonary function

    The phrenic nerve (C3-C5) is blocked in virtually all interscalene blocks, causing ipsilateral hemidiaphragm paresis; in patients with severe pulmonary disease this can precipitate respiratory failure.
