Applying Tension to the Transcervical Foley Balloon and Delivery Times in Term Nulliparous Women Undergoing Induction of Labor: A Randomized Controlled Trial.

OBJECTIVE: To investigate the effects of applying tension to a transcervical Foley balloon on delivery time in term nulliparous patients undergoing labor induction. METHODS: This cluster randomized clinical trial included 279 term nulliparous women presenting for labor induction with a plan for cervical ripening through transcervical Foley balloon placement. Participants were assigned to either the tension group (n=138) or the no-tension group (n=141) on the basis of randomized, weekly clusters (26 total clusters). The primary outcome measured was the time from initial Foley balloon insertion to delivery. Secondary outcomes included cesarean delivery rates, peripartum infection, and neonatal intensive care unit (NICU) admission. Our prior data suggested that delivery time in the tension group would be about 1,053 minutes. We estimated a sample size of 260 (130 per group, 26 clusters) on the basis of a 25% difference, power of 80%, and two-sided α of 0.05. RESULTS: A total of 279 term nulliparous patients were included in the analysis. The median time from Foley placement to delivery was 1,596 minutes (range 430-3,438 minutes) for the tension group and 1,621 minutes (range 488-3,323 minutes) for the no-tension group ( P =.8); similar results were noted for time to vaginal delivery. No significant differences were observed in the secondary outcomes, including the rates of cesarean delivery (34.1% vs 29.8%, P =.7), peripartum infection, and NICU admission, between the two groups. CONCLUSION: Applying tension to a transcervical Foley balloon in term nulliparous women undergoing labor induction did not significantly reduce delivery time or improve secondary outcomes.

Update on sex specific risk factors in cardiovascular disease.

Cardiovascular disease (CVD) is the leading cause of death worldwide and accounts for roughly 1 in 5 deaths in the United States. Women in particular face significant disparities in their cardiovascular care when compared to men, both in the diagnosis and treatment of CVD. Sex differences exist in the prevalence and effect of cardiovascular risk factors. For example, women with history of traditional cardiovascular risk factors including hypertension, tobacco use, and diabetes carry a higher risk of major cardiovascular events and mortality when compared to men. These discrepancies in terms of the relative risk of CVD when traditional risk factors are present appear to explain some, but not all, of the observed differences among men and women. Sex-specific cardiovascular disease research-from identification, risk stratification, and treatment-has received increasing recognition in recent years, highlighting the current underestimated association between CVD and a woman's obstetric and reproductive history. In this comprehensive review, sex-specific risk factors unique to women including adverse pregnancy outcomes (APO), such as hypertensive disorders of pregnancy (HDP), gestational diabetes mellitus, preterm delivery, and newborn size for gestational age, as well as premature menarche, menopause and vasomotor symptoms, polycystic ovarian syndrome (PCOS), and infertility will be discussed in full detail and their association with CVD risk. Additional entities including spontaneous coronary artery dissection (SCAD), coronary microvascular disease (CMD), systemic autoimmune disorders, and mental and behavioral health will also be discussed in terms of their prevalence among women and their association with CVD. In this comprehensive review, we will also provide clinicians with a guide to address current knowledge gaps including implementation of a sex-specific patient questionnaire to allow for appropriate risk assessment, stratification, and prevention of CVD in women.

Early vs delayed amniotomy following transcervical Foley balloon in the induction of labor: a randomized clinical trial.

BACKGROUND: The optimal timing of amniotomy during labor induction is a topic of ongoing debate due to the potential risks associated with both amniotomy and prolonged labor. As such, individuals in the field of obstetrics and gynecology must carefully evaluate the associated benefits and drawbacks of this procedure. While amniotomy can expedite the labor process, it may also lead to complications such as umbilical cord prolapse, fetal distress, and infection. Therefore, a careful and thorough examination of the risks and benefits of amniotomy during labor induction is essential in making an informed decision regarding the optimal timing of this procedure. OBJECTIVE: This study aimed to determine if an amniotomy within 2 hours after Foley balloon removal reduced the duration of active labor and time taken to achieve vaginal delivery when compared with an amniotomy ≥4 hours after balloon removal among term pregnant women who underwent labor induction. STUDY DESIGN: This was an open-label, randomized controlled trial that was conducted at a single academic center from October 2020 to March 2023. Term participants who were eligible for preinduction cervical ripening with a Foley balloon were randomized into 2 groups, namely the early amniotomy (rupture of membranes within 2 hours after Foley balloon removal) and delayed amniotomy (rupture of membranes performed more than 4 hours after Foley balloon removal) groups. Randomization was stratified by parity. The primary outcome was time from Foley balloon insertion to active phase of labor. Secondary outcomes, including time to delivery, cesarean delivery rates, and maternal and neonatal complications, were analyzed using intention-to-treat and per-protocol analyses. RESULTS: Of the 150 participants who consented and were enrolled, 149 were included in the analysis. In the intention-to-treat population, an early amniotomy did not significantly shorten the time between Foley balloon insertion and active labor when compared with a delayed amniotomy (885 vs 975 minutes; P=.08). An early amniotomy was associated with a significantly shorter time from Foley balloon placement to active labor in nulliparous individuals (1211; 584-2340 vs 1585; 683-2760; P=.02). When evaluating the secondary outcomes, an early amniotomy was associated with a significantly shorter time to active labor onset (312.5 vs 442.5 minutes; P=.02) and delivery (484 vs 587 minutes; P=.03) from Foley balloon removal with a higher rate of delivery within 36 hours (96% vs 85%; P=.03). Individuals in the early amniotomy group reached active labor 1.5 times faster after Foley balloon insertion than those in the delayed group (hazard ratio, 1.5; 95% confidence interval, 1.1-2.2; P=.02). Those with an early amniotomy also reached vaginal delivery 1.5 times faster after Foley balloon removal than those in the delayed group (hazard ratio, 1.5; 95% confidence interval, 1-2.2; P=.03). A delayed amniotomy was associated with a higher rate of postpartum hemorrhage (0% vs 9.5%; P=.01). No significant differences were observed in the cesarean delivery rates, length of hospital stay, maternal infection, or neonatal outcomes. CONCLUSION: Although an early amniotomy does not shorten the time from Foley balloon insertion to active labor, it shortens time from Foley balloon removal to active labor and delivery without increasing complications. The increased postpartum hemorrhage rate in the delayed amniotomy group suggests increased risks with delayed amniotomy.

Immunosuppressant Medications in Pregnancy.

Pregnant patients are often on immunosuppressant medications, most commonly to manage transplantation or autoimmune disorders. Most immunosuppressant agents, including tacrolimus, corticosteroids, azathioprine, and calcineurin inhibitors, are safe during pregnancy and lactation. However, mycophenolic acid is associated with higher risks of birth defects and should be avoided in pregnancy. Tacrolimus, the commonly used drug in transplantation medicine and autoimmune disorders, requires monitoring of serum levels for dose adjustment, particularly during pregnancy. Although no pregnancy-specific therapeutic range exists, the general target range is 5-15 ng/mL, and pregnant patients may require higher doses to achieve therapeutic levels. Adherence to prescribed immunosuppressive regimens is crucial to prevent graft rejection and autoimmune disorder flare-ups. This review aims to provide essential information about the use of immunosuppressant medications in pregnant individuals. With a rising number of pregnant patients undergoing organ transplantations or having autoimmune disorders, it is important to understand the implications of the use of these medications during pregnancy.

Ischemic heart disease in pregnancy: a practical approach to management.

Ischemic heart disease is a crucial issue during pregnancy. The term is composed of both preexisting conditions and acute coronary syndrome in pregnancy, including pregnancy-associated myocardial infarction, which can have a significant effect on maternal and fetal outcomes. This review provides a complete guide to managing ischemic heart disease in pregnant women, emphasizing the importance of multidisciplinary care and individualized treatment strategies. Cardiovascular disease, particularly ischemic heart disease, is now the leading cause of maternal mortality worldwide. Pregnancy introduces unique physiological changes that increase the risk of acute myocardial infarction, with pregnancy-associated myocardial infarction cases often associated with factors, such as advanced maternal age, chronic hypertension, and preexisting cardiovascular conditions. This review distinguishes between preexisting ischemic heart disease and pregnancy-associated myocardial infarction. It will emphasize the various etiologies of pregnancy-associated myocardial infarction, including coronary atherosclerosis and plaque rupture presenting as ST-elevation myocardial infarction, non-ST-elevation myocardial infarction, and other nonatherosclerotic causes, including spontaneous coronary artery dissection, vasospasm, and embolism. Our study discusses the practical management of ischemic heart disease in pregnancy, with a focus on preconception counseling, risk assessment, and tailored antenatal planning for women with preexisting ischemic heart disease. Moreover, this document focuses on the challenges of diagnosing cardiovascular disease, especially when presented with nonclassical risk factors and presentation. It provides insight into the appropriate diagnostic testing methods, such as electrocardiogram, cardiac biomarkers, and echocardiography. In addition, the review covers various treatment strategies, from medical management to more invasive procedures, including coronary angiography, percutaneous coronary intervention, and coronary artery bypass graft. Special attention is given to medication safety during pregnancy, including anticoagulation, beta-blockers, and antiplatelet agents. The complexities of delivery planning in women with ischemic heart disease are discussed, advocating for a multidisciplinary team-based approach and careful consideration of the timing and mode of delivery. Furthermore, the roles of breastfeeding and postpartum care are explored, emphasizing the long-term benefits and the suitability of various medications during lactation. Lastly, this review provides crucial insights into the management of ischemic heart disease in pregnancy, stressing the need for heightened awareness, prompt diagnosis, and tailored management to optimize maternal and fetal health outcomes.

Care and Monitoring of Pregnant Patients With Left Ventricular Assist Devices.

Cardiovascular disease is one of the leading causes of maternal mortality in the United States. Although still rare, pregnancy in patients with left ventricular assist devices (LVADs) is becoming more common. Typical indications for the use of LVADs in reproductive-aged females include ischemic cardiomyopathy, nonischemic (familial) dilated cardiomyopathy, peripartum cardiomyopathy, and some forms of myocarditis. An LVAD drains blood through a cannula placed into the apex of the left ventricle and then returns it to the proximal aorta bypassing the aortic valve allowing hemodynamic support in parallel with the native circulation. The physiologic changes associated with pregnancy, mainly increased blood volume and hypercoagulability, may adversely affect patients with LVADs, leading to many experts recommending against pregnancy. Maternal-fetal medicine specialists should have a central role within a multidisciplinary team required to provide optimal care for this high-risk group of patients.

Mirror syndrome: a systematic literature review.

OBJECTIVE: This study aimed to review the diagnostic criteria for mirror syndrome and describe its clinical presentation. DATA SOURCES: Databases from PubMed, Scopus, Cochrane Library, ClinicalTrials.gov, and CINAHL were inquired for case series containing ≥2 cases of mirror syndrome from inception to February 2022. STUDY ELIGIBILITY CRITERIA: Studies were included if they reported ≥2 cases of mirror syndrome and included case reports, case series, cohort studies, and case-control studies. STUDY APPRAISAL AND SYNTHESIS METHODS: The studies' quality and risk of bias were independently assessed. Data were tabulated using Microsoft Excel and summarized using narrative review and descriptive statistics. This systematic review was conducted according to the Preferred Reporting Item for Systematic Reviews and Meta-Analyses statement. All eligible references were assessed. Screening of records and data extraction were independently performed, and a third author resolved disagreements. RESULTS: Of 13 citations, 12 studies (n=82) reported diagnostic criteria for mirror syndrome: maternal edema (11/12), fetal hydrops (9/12), placental edema (6/12), placentomegaly (5/12), and preeclampsia (2/12); 12 studies (n=82) described the clinical presentation of mirror syndrome as maternal edema (62.2%), hypoalbuminemia (54.9%), anemia (39.0%), and new-onset hypertension (39.0%); 4 studies (n=36) reported that hemodilution was present in all patients; 8 studies (n=36) reported the etiology of fetal hydrops, with the most common being structural cardiac malformations (19.4%), alpha thalassemia (19.4%), Rh isoimmunization (13.9%), and nonimmune hydrops fetalis (13.9%); and 6 studies (n=47) reported maternal complications, 89.4% of which were major: postpartum hemorrhage (44.7%), hemorrhage requiring blood transfusion (19.1%), intensive care unit admission (12.8%), heart failure (10.6%), pulmonary edema (8.5%), and renal dysfunction (8.5%). In 39 cases, the reported fetal outcomes were stillbirth (66.6%) and neonatal or infant death (25.6%). The overall survival rate among continued pregnancies was 7.7%. CONCLUSION: The diagnostic criteria of mirror syndrome differed considerably among studies. Mirror syndrome clinical presentation overlapped with preeclampsia. Only 4 studies discussed hemodilution. Significant maternal morbidity and fetal mortality were associated with mirror syndrome. Further research is warranted to elucidate the pathogenesis of mirror syndrome to better guide clinicians in identifying and managing the condition.

Anticoagulation Regimens in Pregnancy.

This article explores current recommendations for anticoagulation therapy in pregnancy, including antepartum, intrapartum, and postpartum guidelines. The authors review various screening strategies used to assess whether a patient is an appropriate candidate for anticoagulation during pregnancy and the postpartum period. The article includes dosing regimens, optimal surveillance, and medication reversal. The authors also address the challenges of transitioning between low-molecular-weight heparin and unfractionated heparin. Finally, there is a discussion of intrapartum anticoagulation management, especially as it relates to the administration of regional anesthesia, and the indications for and timing of thromboprophylaxis following delivery.

Left-Handedness in Obstetrics and Gynecology: A Nationwide Survey of U.S. Trainees and Educators.

OBJECTIVE: This study aimed to evaluate the views and influence of left-handedness among obstetrics and gynecology (OBGYN) trainees and educators and to identify perceived obstacles in training by left-handed (LH) trainees. STUDY DESIGN: An online survey was sent to the U.S. Obstetrics and Gynecology training programs. All participants were asked questions on hand preference for various medical and nonmedical activities, as well as on demographics. Participant responses to handedness and their role as a learner or educator directed them toward further questions. Trainees were surveyed on their experience and outlook as a LH physician in OBGYN. Educators were surveyed on their experience and attitudes in working with LH trainees. LH educators were also surveyed on their experience as a LH physician, similar to the LH trainees. Chi-square or Fisher's exact analysis was used as appropriate, with p-value <0.05 considered statistically significant. RESULTS: Responses were received from 21 training programs, totaling 304 individuals. Participants included 205 learners (156 right handed and 49 left handed), and 99 faculty (82 right handed and 17 left handed). A lack of LH surgical instrument availability (93.6%) and difficulty using right-handed (RH) instruments (83%) were notable obstacles reported by LH learners. The majority of LH learners (57.4%) did not consider their handedness to be disadvantageous but did note added difficulty when training under RH mentors when compared with training under LH mentors (66%). In contrast to LH educators, RH educators endorsed added difficulty in instructing operative procedures to LH learners (32.1 vs. 13.3%, p = 0.012). CONCLUSION: LH trainees face unique challenges during their OBGYN training. Educators would benefit from guidance on how best to manage these trainees. Educators should work to adapt surgical and procedural techniques to accommodate LH trainees. KEY POINTS: · LH learners reported more difficulty in training under RH mentors.. · RH mentors reported increased difficulty in educating LH trainees.. · Neither trainees nor educators considered being LH a significant disadvantage..

Hemorrhagic Stroke in Pregnancy.

Hemorrhagic stroke carries a high risk of disability and mortality. The obstetrical population is at increased risk. Prompt diagnosis and maternal stabilization with a multidisciplinary approach are the mainstays in management. Computed tomography head is the diagnostic imaging of choice and is considered safe in pregnancy. Fetal status optimization before neurosurgery and delivery should be considered if the fetus is viable or if worsening maternal condition. Obstetric indications guide the mode of delivery. Cesarean delivery may be indicated to reduce increasing intracranial pressure. Neuraxial anesthesia should be considered to minimize catecholamine surges, reduce sedation, and control blood pressures.

Outpatient Compared With Inpatient Preinduction Cervical Ripening Using a Synthetic Osmotic Dilator: A Randomized Clinical Trial.

OBJECTIVE: To assess whether outpatient cervical ripening with a synthetic osmotic dilator shortens the length of hospital stay in term pregnancies undergoing labor induction. METHODS: Pregnant participants scheduled for labor induction at term with unfavorable cervix (less than 3-cm dilated and less than 60% effaced) and not requiring inpatient maternal or fetal monitoring were consented, and synthetic osmotic dilator rods were inserted on the day of scheduled induction. After reassuring fetal heart tracing, patients randomized to the outpatient group were asked to return 12 hours after insertion or sooner if needed. Those randomized to the inpatient group remained in the hospital. After the first round of ripening, additional ripening, oxytocin, and labor management were left up to the clinical health care professionals. The primary outcome was the proportion of participants with hospital stays longer than 48 hours. We estimated that a sample size of 338 would provide 85% power to detect a 30% difference between groups. RESULTS: From November 2018 to November 2021, 339 participants were randomized (171 inpatient, 167 outpatient, one withdrawal). Four patients in the outpatient group were admitted before12 hours for suspected labor and rupture of membranes, and 19 in the inpatient group had the device removed before 12 hours. The proportion of participants with hospital stays longer than 48 hours was lower in the outpatient group compared with the inpatient group (89 [53%] vs 152 [89%], relative risk [RR] 0.60, 95% CI 0.52-0.70). Patients in the outpatient group had a shorter total length of stay and time from admission to active labor. They were more likely to have a vaginal delivery within 24 hours of admission and were less likely to receive analgesics during ripening. Route of delivery and other maternal and neonatal outcomes were not significantly different between groups. CONCLUSION: Outpatient cervical ripening with a cervical osmotic dilator decreased hospital stay compared with inpatient ripening, without significant adverse outcomes.

Comparative Analysis of Co-Cultured Amniotic Cell-Conditioned Media with Cell-Free Amniotic Fluid Reveals Differential Effects on Epithelial-Mesenchymal Transition and Myofibroblast Activation.

Myofibroblast activation is a cellular response elicited by a variety of physiological or pathological insults whereby cells initiate a coordinated response intended to eradicate the insult and then revert back to a basal state. However, an underlying theme in various disease states is persistent myofibroblast activation that fails to resolve. Based on multiple observations, we hypothesized that the secreted factors harvested from co-culturing amniotic stem cells might mimic the anti-inflammatory state that cell-free amniotic fluid (AF) elicits. We optimized an amnion epithelial and amniotic fluid cell co-culture system, and tested this hypothesis in the context of myofibroblast activation. However, we discovered that co-cultured amniotic cell conditioned media (coACCM) and AF have opposing effects on myofibroblast activation: coACCM activates the epithelial-mesenchymal transition (EMT) and stimulates gene expression patterns associated with myofibroblast activation, while AF does the opposite. Intriguingly, extracellular vesicles (EVs) purified from AF are necessary and sufficient to activate EMT and inflammatory gene expression patterns, while the EV-depleted AF potently represses these responses. In summary, these data indicate that coACCM stimulates myofibroblast activation, while AF represses it. We interpret these findings to suggest that coACCM, AF, and fractionated AF represent unique biologics that elicit different cellular responses that are correlated with a wide variety of pathological states, and therefore could have broad utility in the clinic and the lab.

Cervical Ripening Efficacy of Synthetic Osmotic Cervical Dilator Compared With Oral Misoprostol at Term: A Randomized Controlled Trial.

OBJECTIVE: To evaluate whether a synthetic osmotic cervical dilator is noninferior to oral misoprostol for cervical ripening. METHODS: In an open-label, noninferiority randomized trial, pregnant women undergoing induction of labor at 37 weeks of gestation or more with Bishop scores less than 6 were randomized to either mechanical cervical dilation or oral misoprostol. Participants in the mechanical dilation group underwent insertion of synthetic osmotic cervical dilator rods, and those in the misoprostol group received up to six doses of 25 micrograms orally every 2 hours. After 12 hours of ripening, oxytocin was initiated, with artificial rupture of membranes. Management of labor was at the physician's discretion. The primary outcome was the proportion of women achieving vaginal delivery within 36 hours of initiation of study intervention. Secondary outcomes included increase in Bishop score, mode of delivery, induction-to-delivery interval, total length of hospital stay, and patient satisfaction. On the basis of a noninferiority margin of 10%, an expected primary outcome frequency of 65% for misoprostol and 71% for mechanical methods, and 85% power, a sample size of 306 participants was needed. RESULTS: From November 2018 through January 2021, 307 women were randomized, with 151 evaluable participants in the synthetic osmotic cervical dilator group and 152 in the misoprostol group (there were four early withdrawals). The proportion of women achieving vaginal delivery within 36 hours was higher with mechanical cervical dilation compared with misoprostol (61.6% vs 59.2%), with an absolute difference of 2.4% (95% CI -9% to 13%), indicating noninferiority for the prespecified margin. No differences were noted in the mode of delivery. Tachysystole was more frequent in the misoprostol group (70 [46.4%] vs 35 [23.3%]; P=.01). Participants in the synthetic osmotic cervical dilator group reported better sleep, less unpleasant abdominal sensations, and lower pain scores (P<.05). CONCLUSION: Synthetic osmotic cervical dilator is noninferior to oral misoprostol for cervical ripening. Advantages of synthetic osmotic cervical dilator include a better safety profile and patient satisfaction, less tachysystole, lower pain scores, and U.S. Food and Drug Administration approval.

Differential Gene Expression in Cord Blood of Infants Diagnosed with Cerebral Palsy: A Pilot Analysis of the Beneficial Effects of Antenatal Magnesium Cohort.

The Beneficial Effects of Antenatal Magnesium clinical trial was conducted between 1997 and 2007, and demonstrated a significant reduction in cerebral palsy (CP) in preterm infants who were exposed to peripartum magnesium sulfate (MgSO4). However, the mechanism by which MgSO4 confers neuroprotection remains incompletely understood. Cord blood samples from this study were interrogated during an era when next-generation sequencing was not widely accessible and few gene expression differences or biomarkers were identified between treatment groups. Our goal was to use bulk RNA deep sequencing to identify differentially expressed genes comparing the following four groups: newborns who ultimately developed CP treated with MgSO4 or placebo, and controls (newborns who ultimately did not develop CP) treated with MgSO4 or placebo. Those who died after birth were excluded. We found that MgSO4 upregulated expression of SCN5A only in the control group, with no change in gene expression in cord blood of newborns who ultimately developed CP. Regardless of MgSO4 exposure, expression of NPBWR1 and FTO was upregulated in cord blood of newborns who ultimately developed CP compared with controls. These data support that MgSO4 may not exert its neuroprotective effect through changes in gene expression. Moreover, NPBWR1 and FTO may be useful as biomarkers and may suggest new mechanistic pathways to pursue in understanding the pathogenesis of CP. The small number of cases ultimately available for this secondary analysis, with male predominance and mild CP phenotype, is a limitation of the study. In addition, differentially expressed genes were not validated by qRT-PCR.

Timing of birth and adverse pregnancy outcomes in cases of prenatally diagnosed vasa previa: a systematic review and meta-analysis.

OBJECTIVE: The ideal time for birth in pregnancies diagnosed with vasa previa remains unclear. We conducted a systematic review aiming to identify the gestational age at delivery that best balances the risks for prematurity with that of pregnancy prolongation in cases with prenatally diagnosed vasa previa. DATA SOURCES: Ovid MEDLINE, PubMed, CINAHL, Embase, Scopus, and Web of Science were searched from inception to January 2022. STUDY ELIGIBILITY CRITERIA: The intervention analyzed was delivery at various gestational ages in pregnancies prenatally diagnosed with vasa previa. Cohort studies, case series, and case reports were included in the qualitative synthesis. When summary figures could not be obtained directly from the studies for the quantitative synthesis, authors were contacted and asked to provide a breakdown of perinatal outcomes by gestational age at birth. METHODS: Study appraisal was completed using the National Institutes of Health quality assessment tool for the respective study types. Statistical analysis was performed using a random-effects meta-analysis of proportions. RESULTS: The search identified 3435 studies of which 1264 were duplicates. After screening 2171 titles and abstracts, 140 studies proceeded to the full-text screen. A total of 37 studies were included for analysis, 14 of which were included in a quantitative synthesis. Among 490 neonates, there were 2 perinatal deaths (0.4%), both of which were neonatal deaths before 32 weeks' gestation. In general, the rate of neonatal complications decreased steadily from <32 weeks' gestation (4.6% rate of perinatal death, 91.2% respiratory distress, 11.4% 5-minute Apgar score <7, 23.3% neonatal blood transfusion, 100% neonatal intensive care unit admission, and 100% low birthweight) to 36 weeks' gestation (0% perinatal death, 5.3% respiratory distress, 0% 5-minute Apgar score <7, 2.9% neonatal blood transfusion, 29.2% neonatal intensive care unit admission, and 30.9% low birthweight). Complications then increased slightly at 37 weeks' gestation before decreasing again at 38 weeks' gestation. CONCLUSION: Prolonging pregnancies until 36 weeks' gestation seems to be safe and beneficial in otherwise uncomplicated pregnancies with antenatally diagnosed vasa previa.

Antimicrobial Dressing versus Standard Dressing in Obese Women Undergoing Cesarean Delivery: A Randomized Controlled Trial.

OBJECTIVE: This study aimed to evaluate the effect of a novel antimicrobial dressing on patient satisfaction and health-related quality of life (HRQoL) following a cesarean delivery. STUDY DESIGN: This was an open-label, single-center, two-arm randomized controlled trial. This study was done at the tertiary center, maternal unit, Galveston, TX. Pregnant women with body mass indices ≥35 kg/m2 were screened for eligibility. Women were randomized to ReliaTect Post-Op Dressing (RELIATECT) or standard wound dressing (STANDARD). Primary outcome was patient satisfaction and HRQoL using validated questionnaires. Secondary outcomes were provider satisfaction, surgical site infection (SSI) rates, and wound complications. RESULTS: In total, 160 women were randomized. Population characteristics were not significant among groups. RELIATECT dressing group had an overall higher score of satisfaction and HRQoL compared with STANDARD group. Women in the RELIATECT group reported less incision odor and incisional pain. Compared with the STANDARD group, most women in RELIATECT dressing group reported better daily activities, self-esteem, personal hygiene, body image, and sleep. Providers reported that the RELIATECT dressing allowed better assessment of the surgical incision site, allowed patients to shower early, and did observe less wound dressing leakage. No differences were found in other secondary end points. CONCLUSION: Postcesarean RELIATECT dressing for wound care in pregnant women with obesity had better patient and provider satisfaction as well as better HRQoL scores. Further, level 1 evidence is needed to assess its impact on SSI rates and wound complication, as this trial was not powered to accomplish this goal. KEY POINTS: · This study was conducted to evaluate RELIATECT on patient satisfaction and HRQoL following a cesarean.. · Post-cesarean RELIATECT dressing for wound care had better HRQoL and patient and provider satisfaction scores.. · This is the first randomized controlled trial evaluating RELIATECT dressing in obese pregnant women undergoing cesarean section..
