Resuscitation: LR initiated at 10 ml/%TBSA/hr (TBSA ≥ 15%) – Adults ≥ 40 kg --Add 100 ml/hr for every 10 kg > 80 kg
Increase/Decrease IVF by 20-25% every hour to maintain UOP 30-50 ml/hr
Circumferential Burns: Perform Escharotomies
Assess for abdominal & extremity compartment syndrome (need fasciotomies?)
5% Sulfamylon Soaked Dressing, Sulfamylon Cream (ears), Bacitracin (face)
Keep Warm and manage drainage (bring extra burn pads)
5% Albumin: Start at 24 hr post-burn (unless Difficult Resuscitation Guideline) --ml/hr = (x * %TBSA * kg)/24 30-49% (x=0.3), 50-69% (x=0.4), 70% (x=0.5)

If above inadequate, measure CVP
CVP: Goal 8-10 cmH2O --If < 8, increase fluid rate 20-25%. --If 8-10, add Vasopressin, then Levophed
If above inadequate, consider adding pressor: --Dobutamine (if SCVO2 < 60), Epinephrine, and/or Phenylephrine
Consider/treat missed injury, acidemia, adrenal insufficiency, and hypocalcemia
If UOP < 30 but MAP, CVP, and SCVO2 at goal = accept renal insult and stop increasing IVF
