Integrative Review of Nursing Practices in Fetal Therapy.

OBJECTIVE: To synthesize nursing practices related to fetal therapy (intervention to correct or treat a fetal anomaly). DATA SOURCES: We searched electronic databases, including PubMed, Embase, OvidSP, and CINAHL, for all relevant published work. We identified additional resources through discussion with experts in the field, hand searches of relevant resources, and examination of the reference lists of articles in our search results. STUDY SELECTION: Any published literature about fetal therapy in which nursing practices were discussed by nurses. DATA EXTRACTION: We used Whittemore and Knafl's methodology to guide this integrative review (2005). We completed data extraction using an analytic review template organized to compare results to Kim's (2015) theoretical framework for nursing practice. DATA SYNTHESIS: We used qualitative techniques described by Miles, Huberman, and Saldaña (2014) to code and thematically interpret the data. Nurses described their contributions to the establishment of fetal therapy programs through the development of entirely new technical and caring skills and their work in relation to care quality, clinician education, ethics, research, and health policy. Data were synthesized under three philosophies of nursing practice: therapy, care, and professional work. CONCLUSION: Nurses have made important contributions to the evolving practice of fetal therapy, a nuanced practice that is critical to the development and provision of comprehensive patient- and family-centered care. Clinical implications of this review include practical recommendations for enhanced support of nursing practice in fetal therapy, which includes the provision of reliable forums to learn and share feedback about nursing practice in this field. Future work should focus on increasing understanding and visibility of nursing in fetal therapy through interdisciplinary evidence-based practice development.

Prenatal growth characteristics and pre/postnatal management of bronchopulmonary sequestrations.

PURPOSE: The prenatal natural history of intralobar and extralobar bronchopulmonary sequestrations (BPSs), including lesion growth patterns and need for prenatal intervention, have not been fully characterized. We review our series of BPSs to determine their natural history and outcomes in the context of the need for prenatal intervention. METHODS: A retrospective review of the pre/postnatal course of 103 fetuses with an intralobar (n=44) or extralobar BPS (n=59) managed at a single institution between 2008 and 2015 was performed. Outcomes included prenatal lesion growth trajectory, presence of hydrops, need for prenatal intervention, survival, and postnatal surgical management. RESULTS: Most extralobar (71%) and intralobar BPSs (94%) decreased in size or became isoechoic from initial to final evaluation. Peak lesion size occurred at 26-28weeks gestation. Eight fetuses developed hydrothorax, four of which (all extralobar BPSs) also developed hydrops. All four hydropic fetuses received maternal betamethasone, and three hydropic fetuses underwent thoracentesis and/or thoracoamniotic shunt placement with subsequent hydrops resolution. All fetuses survived. Forty-one intralobar (93%) and 35 extralobar BPSs (59%) were resected after birth. CONCLUSIONS: BPSs tend to decrease in size after 26-28weeks gestation and rarely require fetal intervention. Lesions resulting in hydrothorax ± hydrops can be effectively managed with maternal steroids and/or drainage of the hydrothorax. LEVEL OF EVIDENCE: IV.

Chorioamniotic membrane separation and preterm premature rupture of membranes complicating in utero myelomeningocele repair.

BACKGROUND: Since the results of the Management of Myelomeningocele Study were published, maternal-fetal surgery for the in utero treatment of spina bifida has become accepted as a standard of care alternative. Despite promise with fetal management of myelomeningocele repair, there are significant complications to consider. Chorioamniotic membrane separation and preterm premature rupture of membranes are known complications of invasive fetal procedures. Despite their relative frequency associated with fetal procedures, few data exist regarding risk factors that may be attributed to their occurrence or the natural history of pregnancies that are affected with chorionic membrane separation or preterm premature rupture of membranes related to the procedure. OBJECTIVE: The objective of this study was to review chorioamniotic membrane separation and preterm premature rupture of membranes in a cohort of patients undergoing fetal management of myelomeningocele repair including identification of risk factors and outcomes. STUDY DESIGN: This was a retrospective review of patients undergoing fetal management of myelomeningocele repair and subsequent delivery from January 2011 through December 2013 at 1 institution. Patients were identified through the institutional fetal management of myelomeningocele repair database and chart review was performed. Perioperative factors and outcomes among patients with chorioamniotic membrane separation and preterm premature rupture of membranes were compared to those without. Risk factors associated with the development of chorioamniotic membrane separation and preterm premature rupture of membranes were determined. RESULTS: A total of 88 patients underwent fetal management of myelomeningocele repair and subsequently delivered during the study period. In all, 21 patients (23.9%) were diagnosed with chorioamniotic membrane separation by ultrasound and preterm premature rupture of membranes occurred in 27 (30.7%). Among the chorioamniotic membrane separation patients, 10 (47.6%) were diagnosed with global chorioamniotic membrane separation and 11 (52.4%) with local chorioamniotic membrane separation. Earlier gestational age at the time of fetal surgery was a significant risk factor for the development of chorioamniotic membrane separation (P = .01) and preterm premature rupture of membranes (P < 0.0001). Chorioamniotic membrane separation was significantly associated with preterm premature rupture of membranes (59.1% vs 21.2%, P = .008) and earlier gestational age at delivery (32.1 ± 4.2 vs 34.4 ± 3.5 weeks, P = .01). The average number of days from chorioamniotic membrane separation to preterm premature rupture of membranes was 11.0 ± 10.1 and from chorioamniotic membrane separation to delivery was 31.0 ± 22.5. The mean time interval between fetal management of myelomeningocele repair and preterm premature rupture of membranes was 47.9 days. Mean latency period from preterm premature rupture of membranes to delivery was 25 days. Gestational age at delivery was significantly lower in patients with preterm premature rupture of membranes (31.6 ± 3.4 vs 34.9 ± 3.5 weeks, P = .0001). Using logistic regression analysis, nulliparity, gestational age at fetal management of myelomeningocele repair, and membrane separation remained significant risk factors for preterm premature rupture of membranes. CONCLUSION: Chorioamniotic membrane separation after fetal management of myelomeningocele repair is a significant risk factor for subsequent development of preterm premature rupture of membranes and preterm delivery. Fetal management of myelomeningocele repair <23 weeks is associated with higher rates of preterm premature rupture of membranes and chorioamniotic membrane separation. Therefore fetal management of myelomeningocele repair should be deferred until ≥23 weeks to mitigate these complications. Nulliparity also appears to increase the risk for preterm premature rupture of membranes.

Fetal myelomeningocele repair: the post-MOMS experience at the Children's Hospital of Philadelphia.

BACKGROUND: Fetal myelomeningocele (fMMC) repair has become accepted as a standard of care option in selected circumstances. We reviewed our outcomes for fMMC repair from referral and evaluation through surgery, delivery and neonatal discharge. MATERIAL AND METHODS: All patients referred for potential fMMC repair were reviewed from January 1, 2011 through March 7, 2014. Maternal and neonatal data were collected on the 100 patients who underwent surgery. RESULTS: 29% of those evaluated met the criteria and underwent fMMC repair (100 cases). The average gestational age was 21.9 weeks at evaluation and 23.4 weeks at fMMC repair. Complications included membrane separation (22.9%), preterm premature rupture of membranes (32.3%) and preterm labor (37.5%). Average gestational age at delivery was 34.3 weeks and 54.2% delivered at ≥35 weeks. The perinatal loss rate was 6.1% (2 intrauterine fetal demises and 4 neonatal demises); 90.8% of women delivered at the Children's Hospital of Philadelphia and 3.4% received transfusions. With regard to the neonates, 2 received ventriculoperitoneal shunts prior to discharge; 71.1% of neonates had no evidence of hindbrain herniation on MRI. Of the 80 neonates evaluated, 55% were assigned a functional level of one or more better than the prenatal anatomic level. CONCLUSION: In an experienced program, maternal and neonatal outcomes for patients undergoing fMMC repair are comparable to results of the MOMS trial.

Maternal, fetal, and neonatal care in open fetal surgery for myelomeningocele.

Fetal myelomeningocele closure (fMMC) was demonstrated in a randomized, prospective clinical trial to improve outcomes for children diagnosed prenatally. Complex care of the maternal/fetal dyad undergoing fetal surgery requires a well-coordinated multidisciplinary team. Nurses in many roles are essential members of the team that cares for these women across the continuum. In this article we discuss the care of the woman, fetus, and family from initial contact through the discharge of the neonate.
