ABA Pain Medicine common mistakes

Memorize a single precise sentence and rehearse it: gabapentinoids bind the alpha-2-delta auxiliary subunit of presynaptic voltage-gated calcium channels, reducing calcium influx and release of glutamate, substance P, and CGRP, with no direct action at GABA receptors. Then derive the clinical corollaries from that mechanism: dose adjustment in renal impairment, additive sedation with other central depressants, and a withdrawal syndrome on abrupt discontinuation that is not reversed by flumazenil or explained by GABA-receptor occupancy.

Build a two-column grid you can reproduce from memory. In the lumbar spine, roots exit below the same-numbered vertebra, so a paracentral L4-L5 herniation catches the traversing L5 root while a far-lateral foraminal herniation catches the exiting L4 root. In the cervical spine, roots exit above the same-numbered vertebra, so a paracentral C5-C6 herniation catches C6. Pair each row with a bedside finding (motor, reflex, sensory territory) so the anatomy is anchored to a clinical sign rather than to a number.

Adopt a fixed pre-scan routine for every pain vignette: before reading the options, scan the stem once specifically for the red-flag cluster (age over 50 with new pain, cancer history, fever, night or rest pain, weight loss, intravenous drug use, immunosuppression, trauma, bowel or bladder change, saddle anesthesia, progressive weakness). If any are present, the first correct action is diagnostic workup, not therapy. Practice by writing the workup step for each flag next to it.

Use a fixed three-step method every time: calculate the equianalgesic dose, reduce it by roughly 25 to 50 percent to account for incomplete cross-tolerance (using the smaller reduction when pain is poorly controlled and the larger reduction when the patient is elderly, frail, or has respiratory risk), then prescribe scheduled plus as-needed doses and set a defined reassessment interval. Treat methadone rotation and transdermal fentanyl conversion as separate topics requiring specific ratio knowledge and, in the case of methadone, specialist involvement. State the reduction step explicitly in your answer choices.

Practice sorting the same behavior into each category. Physical dependence is expected pharmacology and produces withdrawal on cessation. Tolerance is loss of effect at a stable dose. Pseudoaddiction describes request-driven behavior that resolves when pain is adequately treated. Opioid use disorder requires a patterned set of DSM-5 criteria over twelve months (for example craving, use despite harm, failure to fulfill obligations) and is never diagnosed from a single early refill. Write the discriminating feature for each category on a single card and rehearse it before the exam.

Commit an agent-specific interval table to memory organized by class (antiplatelets, warfarin, direct oral anticoagulants, unfractionated heparin, low-molecular-weight heparin, fondaparinux, thrombolytics) with the neuraxial versus peripheral distinction and the renal-function caveat for renally cleared agents. In every procedural vignette, make documenting the last dose, the planned hold, and the restart plan an explicit step in your answer, and consider bleeding risk against the benefit of the procedure rather than defaulting to proceeding.

Keep a short post-procedure red-flag list and run it consciously: fever, new or worsening neurologic deficit, bowel or bladder dysfunction, saddle anesthesia, meningismus, and postural headache that worsens upright. Any of these after a neuraxial procedure mandates urgent imaging, typically magnetic resonance imaging with contrast, plus laboratory studies and urgent specialist consultation rather than symptomatic treatment. Separately rehearse local anesthetic systemic toxicity: stop the injection, secure the airway, and give the weight-based lipid emulsion bolus followed by infusion.

Learn to use validated instruments by name and purpose (pain catastrophizing scale, fear-avoidance beliefs questionnaire, depression and anxiety screens, pain anxiety symptom scale) and to interpret them. Practice explaining central sensitization in non-stigmatizing language that frames the nervous system as sensitized rather than the patient as exaggerating. Then pair the finding with a specific referral: cognitive behavioral therapy, acceptance and commitment therapy, graded exposure, or pain neuroscience education, with functional goals attached.

Use a template for any comprehensive-care item: measurable functional goals stated by the patient, the specific modalities and who delivers each (physician, psychologist, physical therapist, pharmacist, nursing), a scheduled reassessment interval with defined success criteria, and the safety infrastructure (prescription drug monitoring program check, single prescriber agreement, naloxone, bowel regimen, taper or exit strategy). Practicing this template turns a vague answer into a defensible one.

For consent, rehearse a four-part script: the diagnosis and proposed procedure, the material risks, the reasonable alternatives including doing nothing, and the expected benefit in functional terms, all confirmed with teach-back. For boundaries, apply the rule rather than the impulse: do not provide care to family or close friends except in emergencies, explain why, and arrange transfer with a chaperone and clear documentation. Remember that disclosure of an error is an obligation, not a discretionary courtesy.
