Management of Sulfuric Acid Chemical Burns

Immediate Decontamination (First Priority)

The American Heart Association recommends immediate irrigation with copious running water for at least 15 minutes to reduce full-thickness burns and hospital length of stay 1
Begin continuous irrigation with running water within seconds to minutes of exposure, as outcomes are directly dependent on how quickly decontamination begins 1
Continue irrigation for a minimum of 15 minutes, as this duration is specifically recommended for caustic chemical exposures including sulfuric acid 1, 2
If dry sulfuric acid powder is present, brush it off before water irrigation to prevent exothermic reactions 1
Remove all contaminated clothing, jewelry, shoes, and surrounding materials immediately to prevent the chemical from being trapped against the skin and causing continued injury 1, 2
Use personal protective equipment during decontamination to avoid contaminating healthcare providers 1

Check for respiratory involvement, such as circumoral burns, oropharyngeal burns, carbonaceous sputum, or difficulty breathing, which indicate inhalation injury and significantly increase mortality 3, 2
Assess for ocular exposure, as sulfuric acid eye contact requires immediate continuous irrigation and ophthalmology consultation 4
Call EMS immediately if respiratory symptoms are present, systemic symptoms develop, or the burn involves large areas, face, hands, feet, or genitals 1, 2

For adults with burns ≥10% TBSA or children with burns ≥5% TBSA, initiate aggressive fluid resuscitation immediately, using 20 mL/kg of balanced crystalloid solution (Ringer's Lactate preferred) within the first hour 3, 5, 6
Calculate 24-hour fluid requirements using the Parkland formula: 2-4 mL/kg/%TBSA 3
Give half of the calculated 24-hour volume in the first 8 hours post-burn, with the remaining half over the next 16 hours 3
Target urine output of 0.5-1 mL/kg/hour to guide ongoing fluid administration 3
Avoid normal saline (0.9% NaCl) as primary resuscitation fluid, as it increases risk of hyperchloremic metabolic acidosis and acute kidney injury compared to balanced crystalloids 7, 5, 6

Clean wounds with tap water, isotonic saline, or antiseptic solution in a sterile environment 8
Apply appropriate dressings, while avoiding prolonged use of silver sulfadiazine on superficial burns as it delays healing 9, 8
Do NOT apply ice, butter, oil, or other home remedies, as ice causes additional tissue damage 2
Monitor for compartment syndrome in circumferential third-degree burns, which can cause acute limb ischemia 10, 3

Titrate intravenous opioids (short-acting preferred) and ketamine based on validated pain assessment scales 8
Ketamine is particularly effective for burn-induced pain and can reduce morphine requirements 8
Cooling burns <20% TBSA in adults or <10% TBSA in children (if no shock present) can reduce pain and limit burn deepening, but cooling should not exceed 40 minutes to prevent hypothermia 9, 8

Never delay irrigation, as every minute counts, and delayed decontamination dramatically worsens outcomes 1
Avoid "fluid creep" (excessive fluid administration beyond calculated needs) as it leads to compartment syndrome and other complications 3
Do not delay transfer to a burn center for burns involving face, hands, feet, genitals, or those with >10% TBSA in adults or >5% TBSA in children 3, 2
Never break blisters, as this increases infection risk 2

Consult a regional poison control center for chemical-specific treatment recommendations, as sulfuric acid may require specialized management beyond standard irrigation 1, 2
