Acute and chronic respiratory diseases in pregnancy: associations with spontaneous premature rupture of membranes

OBJECTIVE

To examine whether acute and chronic respiratory diseases are associated with an increased risk of spontaneous premature rupture of the membranes (PROM).

METHODS

We used the 1993-2004 National Hospital Discharge Survey data of singleton deliveries in the USA (N = 41 250 539). The International Classification of Diseases Ninth Revision was utilized to identify acute (acute upper respiratory diseases, viral/bacterial pneumonia, and acute bronchitis/bronchiolitis) and chronic (chronic bronchitis and asthma) respiratory conditions and spontaneous PROM. All analyses were adjusted for potential confounders.

RESULTS

The incidence of PROM was 5%, and rates of acute and chronic respiratory conditions were 2.1 and 9.5 per 1000 pregnancies, respectively. Chronic bronchitis was associated with a reduced risk of PROM (RR 0.39, 95% CI 0.31, 0.48). Asthma was significantly associated with PROM at preterm (RR 1.15, 95% CI 1.14, 1.17) and term (RR 1.27, 95% CI 1.23, 1.30). Stratification by race showed that acute upper respiratory disease was associated with preterm PROM in whites (RR 1.90, 95% CI 1.71, 2.11) and blacks (RR 6.76, 95% CI 5.67, 8.07). Viral/bacterial pneumonia was associated with preterm PROM in blacks and term PROM in both races. Asthma was associated with term PROM in blacks but not whites.

CONCLUSIONS

Acute respiratory diseases and asthma during pregnancy are associated with spontaneous PROM, with substantially stronger association among blacks than whites. We speculate that timely diagnosis and treatment, coupled with closely mentoring of pregnant women may help reduce the rate of PROM and associated complications.

Maternal role transition experiences of women hospitalized with PROM: a phenomenological study

This study investigated the subjective experiences of the maternal role transition during the first two weeks of hospitalization for premature rupture of the amniotic membranes (PROM). Thirteen pregnant couples participated in the study by completing interviews. Average gestation of the expectant mothers was 27 weeks and the women were already experiencing fetal movement during the first two weeks of hospitalization for PROM. Lincoln and Cuba's trustworthiness criteria were employed to evaluate methodological rigor. Colaizzi's phenomenological approach was used to analyze the structure of the experience. Four themes emerged: pending loss, concern about the safety of the fetus, identification of maternal roles, and the process of maternal role-making. The results provide a scientific basis for empowering nurses to assist with maternal role transition in high-risk pregnancies in a more sensitive and effective manner.

Nursing care of the patient with preterm premature rupture of membranes

Preterm premature rupture of the membranes (PPROM) is diagnosed when rupture of the amniotic membranes occurs prior to the completion of the 36th week of gestation. PPROM accounts for 25% of all cases of premature rupture of the membranes and is responsible for 30%-40% of all preterm deliveries. In mothers diagnosed with PPROM without evidence of infection, active labor, or fetal compromise, the current standard of care is expectant management. The goal of expectant management is the prolongation of the pregnancy to increase fetal gestational age thus potentially decreasing the effects of prematurity. Expectant management consists of ongoing observation for signs and symptoms of infection, active labor, and/or nonreassuring fetal status. This article provides clinical nursing guidelines for the mother diagnosed with PPROM who is managed expectantly. Eight targeted areas for nursing assessment and intervention are described: preterm labor, side effects of tocolytic therapy, maternal/fetal infection, fetal compromise, side effects of extended bed rest, maternal stress, educational needs, and routine prenatal care.
