Pregnancy and COVID-19: Comparing ICU Outcomes for Pregnant and Nonpregnant Women.

BACKGROUND

This study compares organ dysfunction, treatment strategies, and unfavorable outcome rates between pregnant and nonpregnant women admitted to the ICU with severe COVID-19, highlighting the increased susceptibility of pregnant women to respiratory infections due to physiological changes.

METHODS

A retrospective, age-matched study was conducted at a referral center specializing in critical care for pregnant women. Data from 14 pregnant/postpartum and 11 nonpregnant women were analyzed at ICU admission and on days 3, 5, and 7.

RESULTS

Acute respiratory distress syndrome was diagnosed in 100% of the pregnant/postpartum group and 64% of the nonpregnant group ( = 0.026). Inflammatory parameters were similar between groups, except for lower ferritin levels in the pregnant/postpartum group compared to the nonpregnant (120 vs. 568 µg/L at admission and 90 vs. 616 µg/L on day 3). Creatinine, lactate, and lactate dehydrogenase levels were significantly lower in the pregnant/postpartum group. A reduction in the SOFA score was observed over time in the pregnant/postpartum group (from 7.0 to 4.0 points, = 0.009), while no change was noticed in the nonpregnant group (from 3.0 to 2.5 points, = 0.181). Unfavorable outcome rates were similar, with two patients from each group succumbing to the disease ( = 0.604).

CONCLUSIONS

The findings suggest that pregnancy does not increase the risk of unfavorable outcomes among women with severe COVID-19 receiving ICU treatment. However, additional studies with larger sample sizes are needed to validate these observations.
