1 · Find evidence

PubMed query

Every result is a real PMID returned by NCBI. Nothing on this step is generated.

Ask OpenEvidence ↗

OpenEvidence opens in your own logged-in session with the question filled in. Nothing is fetched on your behalf — read it there, then add what you want to teach as a point below, citing the source it came from.

41 candidate papers

Ticked papers are the ones a deck may be built from. Unticking one needs a reason — the citation gate proves a paper exists, and nothing but you decides whether it should be taught. A tier badge appears where the paper’s publication type is known.

Same-day build

PubMed query

Runs the tiered searches, drafts one point per included paper, runs the citation gate and builds a draft deck — the steps below, unattended. Same-day build — drafted locally (medgemma:27b), confirmed against each abstract. The deck still lands in draft: nothing here approves anything.

2 · Teaching points

Source

A point with no source will not survive the gate. That is the point of the gate.

An international expert panel judged frontal processed EEG adequate for monitoring sedation depth in ICU patients unfit for clinical evaluation, but only after staff complete specific training. PMID 35896766 kept
Across nine trials and 4,648 patients, processed EEG guidance gave a pooled odds ratio for delirium of 0.78 that did not reach significance, with substantial heterogeneity. PMID 35183345 kept
In adults at high risk of awareness having relaxant general anaesthesia, BIS-guided anaesthesia cut confirmed awareness from 11 cases to 2, a relative risk reduction of 82%. PMID 15172773 kept
Isoelectric EEG occurred in 32% of children aged three years or under during anaesthesia, varied from 9% to 88% between hospitals, and was associated with moderate and severe hypotension. PMID 35503999 kept
Processed EEG indices may not reliably reflect hypnotic state in neonates and infants, so read the raw waveform, spectral edge frequency and density spectral array rather than trusting the index alone. PMID 39475857 kept
The POQI consensus recommends EEG monitoring as part of the vital organ monitors, while finding insufficient evidence to recommend it for preventing delirium, neurocognitive disorder or postoperative mortality. PMID 31764163 kept

Checks every citation against PubMed, the DOI resolver, or a live fetch. Points that do not resolve are dropped and shown to you with the reason — never quietly softened.
