The Effect of Shift Timing on Cesarean Delivery Outcomes and Operative Noise Levels.

Objective:  Intraoperative noise exposure has been associated with an increased risk of complications, communication errors, and stress among surgical team members. This study evaluates intraoperative noise levels in cesarean deliveries during different shift times, for example, night shifts, day shifts, and hand-off times between shifts.

Study Design:  This is a secondary analysis of a prospective observational study which measured volume in decibels, percentage of time above safe levels (>60 dB), startle noise events (events with rapid increase of decibel level above baseline noise), and peak levels (>75 dB) for cesarean deliveries during a 3-month preintervention and postintervention study.

The Impact of Environmental and Occupational Noise on Maternal and Perinatal Pregnancy Outcomes.

Importance: Pregnant women are exposed to both occupational and environmental noise during their pregnancy. The association between noise and adverse health outcomes is well known. Less is known about the relationship between noise and its effects on the embryo/fetus and pregnancy.

Noise in cesarean deliveries: a comprehensive analysis of noise environments in the Labor and Delivery operating room and evaluation of a visual alarm noise abatement program.

Background: Cesarean delivery is the most common major surgery worldwide. Noise in healthcare settings leads to impaired communication and concentration, and stress among healthcare providers. Limited information is available about noise at cesarean delivery.

Comparative Diagnostic Performance of Estimated Fetal Weight and Isolated Abdominal Circumference for the Detection of Fetal Growth Restriction.

Objectives: To describe the comparative incidence, detection of small-for-gestational age (SGA), and composite perinatal morbidity (CPM) associated with diagnostic criteria of fetal growth restriction (FGR) by estimated fetal weight (EFW) <10% with those with isolated abdominal circumference (AC) measurements <10%.

Methods: We performed a retrospective cohort study of 1587 patients receiving prenatal care and delivery at our institution. We included all patients with ultrasounds and delivery outcomes available, and excluded terminations, second trimester losses, and pregnancies without ultrasounds.

Universal versus Risk-Based Management of Unknown Group B Streptococcus Status at Term.

 This article estimates and compares public health costs of universal versus risk-based intrapartum antibiotic prophylaxis (IAP) administration for women with unknown Group B streptococcus (GBS) status at term.  The annual number of women in the U.S.

Chlorhexidine-Alcohol Compared with Povidone-Iodine Preoperative Skin Antisepsis for Cesarean Delivery: A Systematic Review and Meta-Analysis.

Objective: To compare chlorhexidine-alcohol with povidone-iodine solutions for skin antisepsis prior to cesarean delivery for the prevention of surgical site infection.

Study Design: Electronic databases MEDLINE, Embase, Scopus, and Clinicaltrials.gov were searched from inception to August 2017.
