Use of neuraxial analgesia for vaginal delivery is associated with a 14% decreased risk for severe maternal morbidity, in part from a reduction in postpartum hemorrhage, new research shows.
The findings indicate that increasing the use of epidural or combined spinal-epidural analgesia may improve maternal health outcomes, especially for Hispanic, Black, and uninsured women who are less likely than White women to receive these interventions, according to the researchers, who published their findings online in JAMA Network Open.
About 80% of non-Hispanic White women receive neuraxial analgesia during labor in the United States, compared with 70% of non-Hispanic Black women and 65% of Hispanic women, according to birth certificate data. Among women without health insurance, half receive epidurals.
Programs that inform pregnant women about epidural use, expand Medicaid, and provide in-house obstetric anesthesia teams “may improve patient participation in clinical decision making and access to care,” study author Guohua Li, MD, DrPH, of Columbia University, New York, said in a statement about the research.
Earlier data from France showed that neuraxial analgesia is associated with reduced risk for severe postpartum hemorrhage. To examine the association between labor neuraxial analgesia and severe maternal morbidity in the United States, Dr. Li and colleagues analyzed more than 575,000 vaginal deliveries in New York hospitals between 2010 and 2017; about half (47.4%) of the women received epidurals during labor.
The researchers focused on severe maternal morbidity, including 16 complications, such as heart failure and sepsis, and five procedures, including hysterectomy and ventilation.
They also considered patient characteristics and comorbidities and hospital-related factors to identify patients who were at higher risk for injury or death.
Severe maternal morbidity occurred in 1.3% of the women. Of the 7,712 women with severe morbidity, more than one in three (35.6%) experienced postpartum hemorrhage.
The overall incidence of severe maternal morbidity was 1.3% among women who received an epidural injection and 1.4% among those who did not. In a weighted analysis, the adjusted odds ratio of severe maternal morbidity associated with epidurals was 0.86 (95% confidence interval, 0.82-0.90).
The study is limited by its observational design and does not prove causation, the authors acknowledged.
“Labor neuraxial analgesia may facilitate early evaluation and management of the third stage of labor to avoid escalation of postpartum hemorrhaging into grave complications and death,” study author Jean Guglielminotti, MD, PhD, an anesthesiologist at Columbia University, said in a statement.
Concerning trends
The Department of Health & Human Services has labeled severe maternal morbidity a public health priority. Recent data from the Centers for Disease Control and Prevention show an increase in maternal mortality rates and worsening disparities by race and ethnicity.
According to the CDC, 861 women died of maternal causes in 2020, up from 754 in 2019. The rate of maternal mortality increased from 20.1 to 23.8 deaths per 100,000 live births.
For Black women, however, the maternal mortality rate was far higher: 55.3 deaths per 100,000 live births – nearly triple the figure of 19.1 per 100,000 for White women. Between 2019 and 2020, the mortality rate increased significantly for Black and Hispanic women, but not White mothers.
Researchers affiliated with University of Toronto and the Hospital for Sick Children agreed in an accompanying editorial that more access to neuraxial labor analgesia for vaginal delivery might improve maternal health outcomes and “may be a strategy well worth pursuing in public health policy.”
The intervention is relatively safe and can “alleviate discomfort and distress,” they wrote.
Neuraxial anesthesia in surgical procedures has been shown to decrease the risk for complications like deep vein thrombosis, pulmonary embolus, transfusion requirements, and kidney failure, said editorialists Evelina Pankiv, MD; Alan Yang, MSc; and Kazuyoshi Aoyama, MD, PhD.
Benefits potentially could stem from improving blood flow, mitigating hypercoagulation, or reducing surgical stress response. But there are rare risks to consider as well, including hemorrhage, infection, and neurologic injury, they added.
Guglielminotti disclosed grants from the National Institute on Minority Health and Health Disparities. Dr. Aoyama reported receiving grants from the Perioperative Services Facilitator Grant Program and Hospital for Sick Children. The other authors disclosed no relevant financial relationships.
