Unexpected term NICU admissions: a marker of obstetrical care quality?
Unexpected admissions of term neonates to the neonatal intensive care unit and unexpected postnatal complications have been proposed as neonatal-focused quality metrics for intrapartum care. Previous studies have noted significant variation in overall hospital neonatal intensive care unit admission rates; however, little is known about the influence of obstetric practices on these rates or whether variation among unanticipated admissions in low-risk, term neonates can be attributed to systemic hospital practices. ⋯ This study contributes to the currently limited understanding of term, neonatal intensive care unit admission rates as a marker of obstetrical care quality. We demonstrated that significant variation exists in hospital unexpected neonatal intensive care unit admission rates and that certain intrapartum events are associated with an increased risk for neonatal intensive care unit admission after delivery. However, the between-hospital variation was low. Unmeasured confounders and extrinsic factors, such as neonatal intensive care unit bed availability, may limit the ability of unexpected term neonatal intensive care unit admissions to meaningfully reflect obstetrical care quality.

Hyperoxygenation in pregnancy exerts a more profound effect on cardiovascular hemodynamics than is observed in the nonpregnant state.
Supplemental oxygen is administered to pregnant women in many different clinical scenarios in obstetric practice. Despite the accepted uses for maternal hyperoxygenation, the impact of hyperoxia on maternal hemodynamic indices has not been evaluated. As a result, there is a paucity of data in the literature in relation to the physiological changes to the maternal circulation in response to supplemental oxygen. ⋯ Hyperoxygenation during the third trimester is associated with a fall in maternal cardiac index and a rise in systemic vascular resistance without recovery to baseline levels at 10 minutes after cessation of hyperoxygenation. The hemodynamic changes that were observed in this study in response to hyperoxygenation therapy during pregnancy could counteract any intended increase in oxygen delivery. The observed maternal effects of hyperoxygenation call for a reevaluation of the role of hyperoxygenation treatment in the nonhypoxemic pregnant patient.

SMFM Consult Series #47: Sepsis during pregnancy and the puerperium.
Maternal sepsis is a significant cause of maternal morbidity and mortality and is a preventable cause of maternal death. The purpose of this guideline is to summarize what is known about sepsis and to provide guidance for the management of sepsis in pregnancy and the postpartum period. The following are SMFM recommendations: (1) we recommend that sepsis and septic shock be considered medical emergencies and that treatment and resuscitation begin immediately (GRADE 1B); (2) we recommend that providers consider the diagnosis of sepsis in pregnant patients with otherwise unexplained end-organ damage in the presence of an infectious process, regardless of the presence of fever (GRADE 1B); (3) we recommend that empiric broad-spectrum antibiotics be administered as soon as possible, ideally within 1 hour, in any pregnant woman in whom sepsis is suspected (GRADE 1B); (4) we recommend obtaining cultures (blood, urine, respiratory, and others as indicated) and serum lactate levels in pregnant or postpartum women in whom sepsis is suspected or identified, and early source control should be completed as soon as possible (GRADE 1C); (5) we recommend early administration of 1-2 L of crystalloid solutions in sepsis complicated by hypotension or suspected organ hypoperfusion (GRADE 1C); (6) we recommend the use of norepinephrine as the first-line vasopressor during pregnancy and the postpartum period in sepsis with persistent hypotension and/or hypoperfusion despite fluid resuscitation (GRADE 1C); (7) we recommend against immediate delivery for the sole indication of sepsis and that delivery should be dictated by obstetric indications (GRADE 1B).

Observational StudyOpioid use after laparoscopic hysterectomy: prescriptions, patient use, and a predictive calculator.
In the setting of America's opioid epidemic, judicious postoperative opioid prescribing is important. Gynecologists lack standard guidelines about postoperative opioid prescriptions. ⋯ On average, surgeons prescribed 4 times the amount of opioids than was needed for patients undergoing laparoscopic hysterectomy for acute postoperative pain control. Individualizing patients' opioid prescriptions based on preoperative risk factors could help reduce excess prescription opioids.

Multicenter Study Comparative StudyMaternal and newborn outcomes with elective induction of labor at term.
A growing body of evidence supports improved or not worsened birth outcomes with nonmedically indicated induction of labor at 39 weeks gestation compared with expectant management. This evidence includes 2 recent randomized control trials. However, concern has been raised as to whether these studies are applicable to a broader US pregnant population. ⋯ Elective induction of labor at 39 weeks gestation is associated with a decrease in cesarean birth in nulliparous women, decreased pregnancy-related hypertension in multiparous and nulliparous women, and increased time in labor and delivery. How to use this information remains the challenge.
