Introduction:

the study of extreme maternal morbidity reduces maternal mortality.

Objective:

To identify the risk factors of extreme maternal morbidity in an intensive care unit.

Method:

a case-control study was developed in women admitted to the Intensive Care Unit of the "Carlos Manuel de Céspedes" hospital in Bayamo, Granma, from January 1, 2016 to December 31, 2017. 214 accepted. patients, with a distribution of 73 cases and 141 controls. Clinical and epidemiological variables were included. For the statistical analysis of the risk factors, the strength of the association with the Odds Ratio (OR) and its confidence intervals (95% CI) was measured and a multivariate analysis was performed with a logistic regression model.

Results:

the average age of patients with extreme maternal morbidity was 25.6 years. 84.9% entered the puerperium and 67.1% due to obstetric causes. In the univariate analysis, the risk factors for the development of extreme maternal morbidity were gestational age greater than 36 weeks, the puerperium, cesarean section and comorbidity. The multivariate analysis showed that the factor with the most important independent influence was the puerperium stage (OR 5.8, 95% CI 1.9-17.4, p = 0.002) and comorbidity (OR 2.1, 95% CI 0.9-4.5, p = 0.059)

Conclusions:

Among the risk factors for extreme maternal morbidity, comorbidity, gestational age greater than 36 weeks, puerperium and cesarean section were identified.
