Abstract:
Introduction: Maternal shock is an important contributor to severe maternal morbidity and mortality. Although there is some data on hypovolemic shock in pregnancy, the literature on maternal shock is remarkably limited. Methods: Data from the National Inpatient Sample with delivery hospitalizations from 2009 to 2019 were used for the data extraction. Diagnosis codes from the International Classification of Diseases, 9 th and 10th Revision for common cardiovascular disease (CVD) conditions, adverse pregnancy and fetal outcomes, and delivery complications including shock, were used. Multivariable logistic regression was performed to assess the predictors and outcomes associated with maternal shock. Results: A total of 41,573,217 delivery hospitalizations were analyzed, of which 13,217 were complicated by maternal shock. The trend of maternal shock was seen to rise from 20 to 45 per 100,000 hospitalizations over the study period (Fig 1A). Traditional cardiovascular risk factors and diseases (e.g., hypertension and heart failure) were significant predictors of maternal shock(Fig 1B). The presence of coagulopathy (Odds Ratio [OR]: 16.2, 95% CI: 15.4-17.0) and peripheral arterial disease (OR: 6.4, 95% CI: 4.9-8.2) were strong predictors of maternal shock. All-cause in-hospital mortality (3.82%), pre-eclampsia (10.78%) and cardiac arrest (5.69%), (all p 〈 0.001), were adverse outcomes that were significantly associated with maternal shock. Conclusions: Overall, the trend of maternal shock was seen to increase more than 2-fold per 100,000 hospitalizations over the 10-year study period. Patients hospitalized for delivery with co-morbid CVD conditions such as heart failure, coagulopathy, and peripheral arterial disease are at an increased risk of developing maternal shock and must be monitored more closely. Subsequent research should focus on characterizing the types of shock and treatment strategies in this population.
