›1-1.5 mg/kg IV bolus then 1-4 mg/min infusion
›Titrate to arrhythmia suppression
›Monitor for lidocaine toxicity
›Arrhythmia treatment per ACLS protocols
›Ventricular fibrillation
›Defibrillation 200 J biphasic immediately
›Epinephrine 1 mg IV every 3-5 minutes
›Amiodarone 300 mg IV after third shock
›Ventricular tachycardia with pulse
›Cardioversion 100 J synchronized if hemodynamically unstable
›Amiodarone 150 mg IV over 10 minutes if stable
›Supraventricular tachycardia
›Adenosine 6 mg IV rapid push; repeat 12 mg if no response
›Rate control with beta-blocker if hemodynamically stable
›Avoid class IA antiarrhythmics (quinidine, procainamide)
›May worsen phenol-induced QT prolongation
›IV fluid resuscitation goals
›Parkland formula for burns > 20% TBSA
›4 mL/kg/% TBSA of lactated Ringer's in first 24 hours
›Half in first 8 hours from time of burn
›Half over next 16 hours
›Modified Brooke formula alternative
›2 mL/kg/% TBSA lactated Ringer's in first 24 hours
›Urine output target
›0.5-1 mL/kg/hour in adults
›1 mL/kg/hour in children
›Increase target if myoglobinuria or hemoglobinuria
›Forced diuresis for phenol metabolite clearance
›Furosemide 20-40 mg IV if adequate fluid resuscitation confirmed
›Maintain urine output 1-2 mL/kg/hour
›Alkalinize urine with sodium bicarbonate if myoglobinuria
›Post-decontamination wound management
›Standard burn wound dressings
›Silver sulfadiazine 1% cream to burn wound
›Modern alternatives: silver-containing dressings, mafenide acetate
›Change every 24-48 hours
›Tetanus prophylaxis
›Tetanus toxoid 0.5 mL IM if last booster > 5 years
›Tetanus immunoglobulin 250 units IM if unvaccinated or unknown
›No prophylactic systemic antibiotics
›Antibiotics reserved for clinical infection
›Wound swab culture if infection develops
›Escharotomy for circumferential burns
›Compartment pressure > 30 mmHg is indication
›Distal ischemia is clinical indication
›Burn surgery consultation
Analgesia and supportive care
›Pain management
›Opioids for moderate-severe pain
›Morphine 0.05-0.1 mg/kg IV every 2-4 hours titrated
›Fentanyl 1-2 mcg/kg IV for procedural pain
›NSAIDs as adjunct if no contraindication
›Avoid if renal toxicity developing
›Note: phenol local anesthetic effect may mask pain
›Do not undertreat based on reported comfort
›Seizure management
›Lorazepam 0.05-0.1 mg/kg IV for active seizures
›Levetiracetam 20-30 mg/kg IV for refractory seizures
›Treat underlying cause: correct hypoxia, metabolic derangements
›Airway management for inhalation injury
›Early intubation before edema progresses
›Video laryngoscope preferred for anticipated difficult airway
›RSI with ketamine 1.5 mg/kg IV and succinylcholine 1.5 mg/kg IV
›Ventilator settings
›Tidal volume 6-8 mL/kg ideal body weight
›PEEP 5-8 cmH2O initial
›SpO2 target 95-98%
