The Coronavirus Disease-2019 (COVID-19) pandemic has brought catastrophic impact on the world since the beginning of December 2019. Extra precautionary measures against COVID-19 during and after delivery are pivotal to ensure the safety of the baby and health care workers. Based on current literature, it is recommended that delivery decisions be discussed between obstetricians and neonatologists prior to delivery, and designated negative pressure delivery rooms should be arranged for COVID person under investigation (PUI). During delivery, a minimal number of experienced staff attending delivery should don personal protective equipment (PPE) and follow the neonatal resuscitation program (NRP). Positive pressure ventilation is best used in a negative pressure room if available. At-risk babies should be transported in an isolette, and tested for COVID-19 in a negative pressure room soon after bathing. Skin-to-skin contact and breast milk feed should continue under certain circumstances. Although newborns with COVID-19 infections often present with symptoms that mimic sepsis and one third of affected patients may demand some form of respiratory support, short-term prognoses are favorable and most recover within two weeks of symptoms onset. In this article, we will further elaborate on topics covering timing and mode of delivery, antenatal steroid, vertical transmission, delivery room management, airway management, transport, testing and isolation after birth, skin-to-skin contact, breast milk feeding, clinical features, outcomes, and discharge plans. In addition, we also share our experiences of encountering neonates born of suspected COVID-19 positive mothers.

Objective:To present the complete history of a case with placenta accreta and demonstrate the special clues of ultrasonography finding during whole trimesters from early pregnancy to delivery.Case Report:A multiparous 28-year-old female with a history of multiple cesarean deliveries was found with suspected precesarean section scar pregnancy at 6 weeks of gestation. We performed a series of ultrasonography scans, which revealed placenta previa totalis and placenta accreta at 15 and 32 weeks of gestation, respectively. A well-planned cesarean section with hysterectomy was performed at the 35th week of gestation with massive blood transfusion support, and an alive female baby—with a birth body weight of 2485 g, and Apgar score of 9 at the 1st minute and 10 at the 5th minute—was born. The intraoperative blood loss was 7000 mL, and no postoperative hemorrhage or other complication occurred.Conclusion:Ultrasonography remains the main tool for diagnosis of morbid adherent placenta with several typical clues, including abnormal vasculature, increased size and numbers of vascular sinus, absence of uterovesicle border or retroplacental hypoechoic zone, and invaded placenta insertion on myometrium. Proper planning prior to the operation and detailed counseling may be necessary, as well as hysterectomy; massive bleeding with transfusion remained the most seen complication.

Background Right ventricular outflow tract obstruction (RVOTO) is the most frequently encountered congenital heart disease in patients with twin –twin transfusion syndrome (TTTS) and is especially prevalent in the recipient twin. In this retrospective study, we evaluated the incidence, prognosis, postnatal management, and perinatal outcomes of and risk factors for RVOTO in the recipient twin in severe TTTS cases which diagnosed before 26 weeks after fetoscopic laser photocoagulation (FLP) at a single center in Taiwan. Methods RVOTO was diagnosed using fetal or postnatal echocardiography. The fetal outcomes evaluated were perinatal survival rate, neonatal brain image anomalies rate, gestational age at delivery, and birth weight. Results Total 187 severe TTTS cases were included; 14 (7.49%) had a recipient twin with RVOTO (12 cases of pulmonary stenosis and 2 of pulmonary atresia). Of these 14 cases, 3 (21.4%) demonstrated improvements in outflow obstruction after FLP, and 11 (78.6%) resulted in perinatal survival. Of the 11 survivors, 5 (45.5%) received transcatheter balloon valvuloplasty to alleviate the RVOTO. The perinatal survival rate, gestational age at delivery, neonatal brain image anomaly rate, and birth weights did not significantly differ between the groups in which the recipient twin had versus did not have RVOTO. Generally, the recipient twin had RVOTO received FLP at a younger gestational age (in weeks; 19.3 ± 2.4 vs. 20.7 ± 2.6, p = 0.048) and had a higher percentage of cases at Quintero stage IV (50.0% vs. 12.1%, p < 0.001) than those in which the recipient twin did not have with RVOTO. Using logistic regression, we discovered that FLP at a younger gestational age (p = 0.046, odds ratio = 0.779) and TTTS at Quintero stage IV (p = 0.001, odds ratio = 7.206) were risk factors for the recipient twin developing RVOTO after FLP in severe TTTS cases. Conclusions The post-FLP perinatal outcomes of cases of severe TTTS in which the recipient twin had versus did not have RVOTO were comparable in this study, which may have been due to the similar gestational ages at delivery and strong influence of high Quintero stages (stages III and IV).

ObjectiveTo report obstetric outcomes in pregnant women with previous pelvic ring injury (PRI) and investigate the correlation between residual pelvic deformity and the mode of delivery.DesignRetrospective cohort study.SettingSingle medical centre in Taiwan.PopulationForty‐one women with PRI histories from 2000 to 2021 who subsequently underwent pregnancy and delivery.MethodsAll patients had complete PRI treatment and radiological follow up for at least 1 year. The demographic data, radiological outcomes after PRI and obstetric outcomes were collected to investigate the potential factors of delivery modes using non‐parametric approaches and logistic regression. Caesarean section (CS) rates among different subgroups were reported.Main outcome measuresComparisons of demographic data and radiological outcomes (Matta/Tornetta criteria and Lefaivre criteria) after PRI among patients who had subsequent pregnancy and underwent vaginal deliveries (VD) or CS.ResultsThere were 14 VD and 27 CS in 41 patients. Nine patients underwent CS because of their PRI history, 12 patients underwent CS for other obstetric indications and 20 underwent trial of labour. Based on the logistic regression model, retained trans‐iliosacral implants did not significantly increase the risk of CS (odds ratio [OR] 1.20; 95% CI 0.17–8.38). Higher pelvic asymmetry value by Lefaivre criteria was a potential risk factor for CS after previous PRI (OR 1.52; 95% CI 1.043–2.213).ConclusionsVD is possible after PRI. Retained trans‐iliosacral implants do not affect the delivery outcome. Residual pelvic asymmetry after PRI by Lefaivre criteria is a potential risk factor for CS.

Objective: To investigate the fetal growth pattern after fetoscopic laser photocoagulation (FLP) in twin-twin transfusion syndrome (TTTS) and the effect of FLP on placental perfusion and intrauterine growth restriction (IUGR) incidence. Methods: TTTS cases with a live delivery of both twins at least 28 days after FLP and with a neonatal follow-up at our hospital at least 60 days after delivery were included. The biometric data obtained before FLP (based on ultrasound); time point M1), upon birth (M2), and at neonatal follow-up (M3) were analyzed. The body weight discordance (BWD) was defined as (estimated fetal weight [body weight] of the recipient twin − estimated fetal weight [body weight] of the donor twin)/(estimated fetal weight [body weight] of the recipient twin) × 100%. Total weight percentile (TWP) was defined as the donor + recipient twin weight percentile; the TWP indirectly reflected the total placental perfusion. Results: the BWDs decreased from M1 to M2 to M3 (24.6, 15.9, and 5.1, respectively, p < 0.001, repeated measurements). The weight percentiles of recipient twins decreased after FLP, that is, from M1 to M2 (53.4% vs 33.6%, respectively, p < 0.001, least significant difference [LSD] test). However, the weight percentiles of donor twins increased after delivery, that is, from M2 to M3 (13.2% vs 26.2%, respectively, p < 0.001, LSD test). Moreover, the TWPs decreased after FLP, that is, from M1 to M2 (66.2% vs 46.8%, respectively, p = 0.002, LSD test) and increased after delivery, that is, from M2 to M3 (46.8% vs 63.2%, respectively, p = 0.024, LSD test). The IUGR incidences in donor twins were significantly lower after FLP (77.4% vs 56.6%, respectively, p = 0.019, McNemar test) and further decreased after delivery (56.6% vs 37.7%, respectively, p = 0.041, McNemar Test); however, no significant difference was observed in recipient twins’ IUGR incidences among M1, M2, and M3. The donor twin had catch- up growth in body weight, height, and head circumference after delivery, and the recipient twin had catch-up growth in only body height after delivery. Conclusions: the BWD decreased after FLP in fetuses with TTTS mainly because of the decreased weight percentiles of recipient twins. Moreover, it further decreased after delivery mainly because of the increased weight percentiles of donor twins. FLP not only decreased placental perfusion but also improved the TTTS prognosis because of reduced BWD and donor twin IUGR incidence.
