941b73f9e5
Finishes Bedside parity. Neonatal, Respiratory, Ventilation, Sepsis,
and Burns replace their LegacyPanel fallbacks. All 15 vanilla
Bedside sub-modules are now real React components.
shared/clinical/fenton.ts — second, higher-accuracy Fenton table
fentonLmsPeditools: 21 GA weeks × 2 sexes (22-42 in 1-week steps)
ported verbatim from public/js/bedside/neonatal.js:20-37. This is
the peditools-derived table that superseded the older hand-rounded
version (still used by the Growth Charts calculator). Adds
calcZNeonatal (|L|<0.001 threshold) + zToPercentileNeonatal
(Abramowitz & Stegun erf form) so neonatal output matches the
vanilla Bedside numbers to 3 decimal places.
neonatalAssess() returns { gaDecimal, gaClass, bwClass,
weightClass, expectedWeight, z, percentile, L, M, S }.
scripts/capture-calc-vectors.js + e2e/fixtures/calc-vectors.json
Adds 8 neonatal vectors (including the 40w5d male 3070g validated
case from the vanilla file's own comment: z = -1.42).
shared/clinical/fenton.test.ts — now covers neonatal too (110 total
vitest cases pass: 19 calculators, 21 fenton, 70 bilirubin).
client/src/pages/BedsidePanels2.tsx — five new panels
• NeonatalPanel — GA+weight+sex inputs drive the Fenton assessment
(gestational-age class, weight-for-GA class, birth-weight
category, Z-score, percentile, expected M). Full NRP pathway
cards (birth→HR<100→HR<60 escalation), NRP drug table scaled
by weight (epi IV/IO/ETT, NS bolus, D10), and 5-element Apgar
scorer with reassuring/moderately-depressed/severely-depressed
guidance.
• RespiratoryPanel — four sub-modes: Asthma (mild/moderate/
severe with full drug tables + "when to intubate" / ABG /
heliox clinical decision boxes), PRAM scorer (0-12),
Westley croup scorer (0-17 with severity-tiered treatment),
Bronchiolitis admission decision tree (age / SpO₂ / hydration
/ distress) with AAP "NOT recommended" list.
• VentilationPanel — target SpO₂ table by population, 6-step
escalation ladder (NC → FM → NRB → HFNC → NIV → intubation)
with live-scaled HFNC flow (1-2 L/kg/min), BVM how-to,
mechanical vent starting settings (TV, rate by age, PEEP,
FiO₂, I:E), gas-exchange adjustment table, and the
oxygenation-vs-ventilation mental model.
• SepsisPanel — Phoenix Sepsis Criteria (JAMA 2024), red-flag
list, age-banded workup + empirical therapy (neonate /
infant / child abx drugs keyed to weight), SSC 2020 first-hour
bundle (0-5 min recognize → >60 min refractory-shock
vasoactive), and resuscitation targets.
• BurnsPanel — full 19-region Lund-Browder age-adjusted table
(ported verbatim), with per-region % input + live TBSA
computation + override. Parkland formula (4 × kg × TBSA,
8h/16h split + per-hr rates), 4-2-1 maintenance, UOP targets,
pearl list (palm rule, no first-degree, analgesia, tetanus),
and ABA burn-center referral criteria.
client/src/pages/BedsidePanels.tsx — dispatch extended to all 15
pills. REAL_BEDSIDE_PANELS now contains every Bedside pill id, so
the legacy-link fallback is dead code that can be pruned later.
Client tsc + vite build + 110/110 vitest tests all green.
