What Researchers Did
Researchers reviewed the current understanding and treatment of carbon monoxide and cyanide poisoning in burned pregnant patients, focusing on the role of hyperbaric oxygen therapy.
What They Found
They found that carbon monoxide (CO) binds fetal hemoglobin 2.5- to 3-fold stronger than maternal hemoglobin, making burned pregnant patients particularly vulnerable. While 100% normobaric oxygen reduces CO half-life from 5 hours to 1 hour, hyperbaric oxygen (HBO2) further decreases it to 20 minutes and is strongly indicated for this patient population. Cyanide intoxication is often a comorbid condition, acting synergistically with CO.
What This Means for Canadian Patients
Canadian healthcare providers treating burned pregnant patients with smoke inhalation should consider hyperbaric oxygen therapy as a crucial intervention to protect both mother and fetus from carbon monoxide and cyanide poisoning. Early diagnosis and aggressive treatment are vital to improve outcomes and reduce the risk of delayed neurological sequelae in this high-risk population.
