Rationale: Malnutrition is a common but often underrecognized issue in critically ill obstetric patients. Nutritional status may influence the duration of mechanical ventilation (MV) and other outcomes in intensive care units (ICUs), yet few studies have addressed this population.

Methods: This retrospective observational study included obstetric patients ≥20 weeks of gestation or up to 6 weeks postpartum admitted to the ICU of Statistical analysis included Mann-Whitney U test and Spearman’s correlation.

Results: At admission, 46.7% of patients were classified as high nutritional risk (mNUTRIC ≥5). The median duration of mechanical ventilation in the high-risk group was 6.5 days (IQR 4.0–9.0), compared to 3.0 days (IQR 2.0–5.0) in the low-risk group (p < 0.001).Serum albumin levels were significantly lower in the high-risk group (2.7 ± 0.3 g/dL vs. 3.5 ± 0.4 g/dL, p < 0.001) and showed a moderate negative correlation with duration of MV (Spearman's r = -0.48, p < 0.01).

Conclusion: Nutritional risk at ICU admission, as assessed by the modified NUTRIC score and serum albumin levels, was significantly associated with prolonged mechanical ventilation and increased ICU length of stay in critically ill obstetric patients.
