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.

32 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.

Ranked on umbilical arterial base excess across 52 trials, norepinephrine, mephentermine and metaraminol were least likely to worsen fetal acid-base status, and ephedrine was the worst agent for nearly every outcome. PMID 31810562 kept
During spinal anesthesia for cesarean delivery, norepinephrine infusion maintains systolic blood pressure while causing less bradycardia and greater heart rate and cardiac output compared to phenylephrine. PMID 25635593 kept
Evidence continues to support phenylephrine as the first-line obstetric vasopressor, with prophylactic infusions more effective and requiring less intervention than intermittent boluses. PMID 28277383 kept
A systematic review of 13 trials found the evidence still too limited to establish an advantage of norepinephrine over phenylephrine, and could not fully rule out an effect on fetal blood gas status. PMID 32012226 kept
As equipotent boluses, norepinephrine 6 micrograms produced bradycardia in 10.7% versus 37.5% with phenylephrine 100 micrograms, and fewer patients needed rescue ephedrine. PMID 30113395 kept
Across 15 trials, norepinephrine and phenylephrine were equally effective for post-spinal hypotension, but norepinephrine reduced maternal bradycardia by 61% on high-quality evidence. PMID 35785931 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.
