ReviewRefractory uterine atony: still a problem after all these years.
Postpartum hemorrhage is a leading cause of maternal morbidity and mortality, and uterine atony is the leading cause of postpartum hemorrhage. Risk factors for uterine atony include induced or augmented labor, preeclampsia, chorio-amnionitis, obesity, multiple gestation, polyhydramnios, and prolonged second stage of labor. Although a risk assessment is recommended for all parturients, many women with uterine atony do not have risk factors, making uterine atony difficult to predict. ⋯ Rigorous studies are lacking, but methylergonovine and carboprost are likely superior to misoprostol. Currently, the choice of second-line agent should be based on their adverse effect profile and patient comorbidities. Surgical and radiologic management of uterine atony includes uterine tamponade using balloon catheters and compression sutures, and percutaneous transcatheter arterial embolization.

Case ReportsTwo cases of severe COVID-19 in gestational week 27 and 28 respectively, after which both pregnancies proceeded to term.
COVID-19 in pregnancy increases the risk of caesarean section. We present two cases of late gestation pregnant women with severe COVID-19. ⋯ These two cases demonstrate the possibility of treating pregnant women with severe COVID-19 with mechanical ventilation in the late second and early third trimesters without them having a pre-term delivery. With a multidisciplinary approach, such management could avoid the maternal risks of surgery during a severe infection and, at the same time, enable term birth with a lower risk of neonatal complications.

Observational StudyAccuracy of cricothyroid membrane identification using ultrasound and palpation techniques in obese obstetric patients: an observational study.
During performance of emergency front of neck access, the final step in management algorithms for the 'can't intubate, can't oxygenate' scenario, accurate identification of the cricothyroid membrane is crucial. Accurate identification using palpation techniques is low, with highest failure rates occurring in obese females. ⋯ Ultrasound-guided cricothyroid membrane localisation was significantly more accurate but slower than the landmark technique in obese obstetric patients. As such, we recommend the use of pre-procedural identification of the cricothyroid membrane in this patient population and formal training of anaesthetists in airway ultrasound.

An audit of the effect of case selection on compliance with a 30-minute audit standard for decision-to-delivery interval at category 1 caesarean section.
Our hospital has an audit standard that ≥90% of women having category 1 (emergency) caesarean section should have a decision-to-delivery interval (DDI) ≤30 min. This audit aimed to identify potential influences of case selection on compliance. ⋯ Compliance with an audit standard for (DDI) at category 1 caesarean section is markedly influenced by the inclusion criteria. For comparability with other publications, it is suggested urgency should be reported as that applied at the point of decision for caesarean section, however, category 1 caesarean section cases following failed operative vaginal delivery in the operating theatre should be identified and reported separately.
