PCG P27 β€” Push dose pressors: your bridge when the BP is trying to leave the building. Mix it right, label it, and have the drip running concurrently. These are buying time β€” not writing prescriptions.
⚑ WHICH AGENT?
β–ΈTRAUMA / Hemorrhagic Shock β†’ Epinephrine push dose
β–ΈNON-TRAUMA / Vasodilatory Shock β†’ Phenylephrine push dose
β–ΈIf bradycardia is contributing β†’ Epinephrine preferred (has chronotropic effect)
Epinephrine (Push Dose)
Target concentration: 10 mcg/mL β€” for TRAUMA / bradycardia
MIXING β€” USING 1:10,000 (0.1 mg/mL)
1
Draw up 1 mL of Epinephrine 1:10,000 (0.1 mg/mL) into a 10 mL syringe
2
Add 9 mL of 0.9% NS β†’ total 10 mL
3
Final: 0.1 mg / 10 mL = 10 mcg/mL
βœ“ 10 mL syringe at 10 mcg/mL β€” label before use

MIXING β€” USING 10 mg/mL VIAL
1
Draw up 1 mL phenylephrine 10 mg/mL

CLINICAL NOTES

Vasopressin Infusion Quick Mix
Per PCG M15 β€” adjunct vasopressor
1
Mix 25 units Vasopressin in 250 mL D5W or NS β†’ 0.1 units/mL
2
Initiate at 0.03 units/min β†’ Rate = 18 mL/hr
3
Obtain consult for dose titration. Typical range 0.01–0.04 units/min
Rate formula: [Dose (units/min) Γ— 60] Γ· 0.1 (units/mL) = mL/hr
0.03 units/min β†’ 18 mL/hr

Pregnancy Category Key β€” FDA Legacy
Reference for the PREG badge on each drug card
βŒ„
A
Adequate, well-controlled human studies show no fetal risk
Safest tier β€” examples: thiamine, folic acid, levothyroxine
B
Animal studies show no risk; no adequate human studies β€” OR β€” animal risk not confirmed in human studies
Generally acceptable β€” examples: acetaminophen, ondansetron, ceftriaxone, famotidine, LMWH, metoclopramide
C
Animal studies show adverse effect; no adequate human studies β€” benefit may justify risk
Most resuscitation drugs β€” examples: epinephrine, norepinephrine, fentanyl, ketamine, amiodarone
D
Positive evidence of human fetal risk β€” but benefit may outweigh risk in life-threatening situations
Use only when nothing safer works β€” examples: midazolam, lorazepam, diazepam, phenobarbital, magnesium (chronic), aspirin (3rd trim)
X
Studies show fetal abnormalities β€” risk clearly outweighs any benefit
Contraindicated in pregnancy β€” examples: methotrexate, isotretinoin, warfarin, statins
N/A
Not formally categorized or not applicable
Topical/non-absorbed (activated charcoal), or used during delivery itself (oxytocin)
⚠ Note: The FDA replaced this letter system with narrative labeling (PLLR) in 2015, but the A/B/C/D/X categories are still widely used in clinical reference and crew shorthand. Categories reflect known risk β€” "C" often means "not adequately studied," not "known dangerous." In a coding pregnant patient, the right drug is the one that keeps her alive.
