What Researchers Did
Researchers retrospectively reviewed the long-term infant outcomes of 28 pregnant women who received hyperbaric oxygen treatment (HBOT) for acute carbon monoxide (CO) poisoning.
What They Found
Out of 28 singleton pregnancies, one fetus was dead before HBOT, and three adverse events (abortion, premature birth, limb malformation) occurred. The remaining 24 patients delivered healthy term infants with normal neurophysiological development, and at a median age of 34 months, none had diagnosed diseases. While clinical severity didn't affect outcomes, pregnancy trimester significantly related to birth weight (P = 0.029) and week of pregnancy correlated with the age of independent walking (P = 0.043).
What This Means for Canadian Patients
This suggests that hyperbaric oxygen treatment for acute carbon monoxide poisoning during pregnancy generally leads to healthy long-term infant outcomes. Canadian pregnant patients exposed to CO poisoning may benefit from HBOT to mitigate potential fetal harm.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a retrospective study, it may be limited by potential confounding factors and reliance on existing medical records.
