A few notes on how it's structured so you can present it confidently: Slides 2 and 13 bookend the argument with the same framing — since ketamine can only tie on efficacy, the debate is decided on tolerability and monitoring, where opioids clearly lead. Repeating it at open and close is a deliberate rhetorical device. Slides 4–6 are your tolerability pillar (predictability → reversibility → titratability), with the naloxone/no-antidote contrast on Slide 5 as your single strongest point. Slides 7–8 are your monitoring pillar, built on the asymmetry: opioids have both an early-warning system (PRODIGY, capnography) and a reversal agent, while ketamine demands heavier monitoring for effects that cannot be reversed. Slides 10–12 handle the marquee trials, rebuttals, and one honesty caveat — pre-empting the opponents' best points makes you more credible under cross-examination.
