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

CLINICAL NOTES
!
Bridge ONLY β€” initiate vasopressor infusion concurrently
!
Onset: 1–2 min. Duration: 5–10 min
!
Do NOT use 1:1,000 concentration for push dose β€” verify vial
Phenylephrine (Push Dose)
Target concentration: 100 mcg/mL β€” for NON-TRAUMA vasodilatory shock
MIXING β€” USING 10 mg/mL VIAL
1
Draw up 1 mL phenylephrine 10 mg/mL
2
Add 99 mL NS β†’ 100 mL total
3
Final: 10 mg / 100 mL = 100 mcg/mL

DOSING
PatientDoseVolumeInterval
Adult100–200 mcg1–2 mLq 2–5 min PRN
Pediatric5–10 mcg/kg0.05–0.1 mL/kgq 3–5 min PRN
CLINICAL NOTES
!
Pure α₁ agonist β€” no chronotropy. Reflex bradycardia possible
!
Avoid if cardiac output already reduced β€” may worsen
!
Bridge ONLY β€” initiate norepinephrine infusion concurrently
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
Y-site compatibility for IV meds + common fluids. Tap any matrix cell to highlight a pair, or use the search/dropdowns. Slamming incompatibles down one line is how you get mystery precipitate and a very bad day.
