RESUMO
OBJECTIVE: To estimate the birth prevalence and 7-year case-fatality rate of peripartum cardiomyopathy for a statewide population by applying the National Institutes of Health Workshop on Peripartum Cardiomyopathy definition, including echocardiographic criteria for left ventricular dysfunction. METHODS: This was an epidemiologic study of residents of North Carolina experiencing an obstetric delivery or a pregnancy-related death before delivery in 2002 through 2003 including 235,599 live births. Potential cases were identified from International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM), pregnancy and cardiovascular codes followed by medical record review, and from the state pregnancy-related mortality file. Only women meeting the established definition including echocardiographic criteria for left ventricular dysfunction and women with diagnoses at autopsy were included. The state death file and the U.S. Social Security Death Index were searched for the years 2002 through 2010 for all cases. RESULTS: A total of 740 potential cases from 70 hospitals were identified from discharge ICD-9-CM codes. The medical records for 698 (94.3%) were located and reviewed. Seventy-eight met inclusion criteria. An additional seven women had diagnoses only at autopsy. The birth prevalence was 1 case for every 2,772 live births or 3.61 cases per 10,000 live births (95% confidence interval 2.88-4.46). The 7-year case-fatality rate was 16.5% (95% confidence interval 10--25.9%). Black non-Hispanic women experienced an almost fourfold increased prevalence and fatality compared with white women. Women older than age 35 years had the highest prevalence. CONCLUSIONS: The racial disparity in both birth prevalence and case-fatality is striking; one in six women died within 7 years. LEVEL OF EVIDENCE: II.

OBJECTIVE: Although the risk of death from complications of pregnancy in the 20th century has decreased dramatically, several lines of evidence suggest that it has not reached an irreducible minimum. To further reduce pregnancy-related mortality, we must understand which deaths are potentially preventable and the changes needed to prevent them. We sought to identify all pregnancy-related deaths in North Carolina and conduct a comprehensive review examining ways in which the number of these deaths could potentially be reduced. METHODS: The North Carolina Pregnancy-Related Mortality Review Committee reviewed all of the 108 pregnancy-related deaths (women who died during or within 1 year of the end of pregnancy from a complication of pregnancy or its treatment) that occurred in the state in 1995-1999. For each death, the committee determined the cause of death, whether it could have been prevented, and if so, the means by which it might have been prevented. RESULTS: Although overall, 40% of pregnancy-related deaths were potentially preventable, this varied by the cause of death. Almost all deaths due to hemorrhage and complications of chronic diseases were believed to be potentially preventable, whereas none of the deaths due to amniotic fluid embolus, microangiopathic hemolytic syndrome, and cerebrovascular accident were considered preventable. Improved quality of medical care was considered to be the most important factor in preventing these deaths. Among African-American women, 46% of deaths were potentially preventable, compared with 33% of the deaths among white women. CONCLUSION: Despite the decline in pregnancy-related mortality rates, almost one half of these deaths could potentially be prevented, mainly through improved quality of medical care. In-depth review of pregnancy-related deaths can help determine strategies needed to continue making pregnancy safer.

PURPOSE: African-American women have a 2- to 4-fold increased risk of pregnancy-related death compared with Caucasian women. We conducted this study to determine if differences in a combination of socioeconomic and medical risk factors may explain this racial disparity in pregnancy-related death. METHODS: Pregnancy-related deaths of African-American (N=60) and Caucasian (N=47) women were identified from review of pregnancy-associated deaths (N=400) ascertained through cause of death on death certificates, electronic linkage of birth and death files, and review of the hospital discharge database for the State of North Carolina, during the period between 1992 and 1998. Controls (N=3404) were randomly selected from all live births for the same 7-year period. Logistic regression was used to model the association between race and pregnancy-related death. RESULTS: The unadjusted odds ratio (OR) for pregnancy-related death for African-Americans compared with Caucasians was 3.07 (95% confidence interval [CI], 2.08, 4.54). After controlling for gestational age at delivery, maternal age, income, hypertension, and receipt of prenatal care, African-American race remained a significant predictor variable (OR 2.65 [95% CI 1.73, 4.07]). CONCLUSIONS: Our analysis confirms that there is a strong association between race and pregnancy-related death, even after adjusting for potential predictors and confounders.

OBJECTIVE: To examine the association between health care services variables and pregnancy-related death using a contemporary geographically defined population and enhanced methods for case identification. METHODS: This is a population-based, case-control study from North Carolina for the 7-year period 1992-1998. Pregnancy-related deaths after a live birth (n = 118) were identified after review of pregnancy-associated deaths (n = 400) ascertained from death certificate codes and linkage of birth and death files. Controls (n = 3697) were randomly selected from all registered live births for the same 7-year period and were not matched with cases. This sample size was sufficient to ensure that the standard errors for subgroup prevalences were less than 1%. The associations between pregnancy-related death and health care services were explored with univariate and multivariable regression analysis. RESULTS: Neither maternity care coordination nor nutritional services were protective. There was no association with source of care, private versus public. The adjusted odds ratio (OR) for pregnancy-related death associated with cesarean delivery was 3.9 (95% confidence interval [CI] 2.5, 6.1). The adjusted OR for pregnancy-related death associated with the receipt of prenatal care was 0.2 (95% CI 0.1, 0.6). CONCLUSION: Removing barriers to and actively promoting use of prenatal care services and decreasing the rate of cesarean deliveries could decrease the number of pregnancy-related deaths.

IMPLICATIONS: A 34-h remifentanil infusion was administered for labor analgesia in a patient with thrombocytopenia and renal insufficiency. Compared with other opioids, remifentanil may produce fewer cumulative effects during prolonged infusion because of its unique metabolism.
