While it is well known that maternal temperature affects fetal heart rate, the exact relationship is not well described. The circumstances accompanying most cases of maternal hypothermia and rewarming (e.g. a drowning event) have precluded a precise quantitative description of this relationship. We describe hypothermia and controlled rewarming during resection of a maternal brain stem tumor in the early third trimester. Continuous electronic fetal heart rate and core temperature monitoring demonstrated a near linear relationship during the development of hypothermia and rewarming. Recognition of the close relationship between maternal temperature and fetal heart rate can help safeguard maternal and fetal health, and prevent unnecessary delivery during non-obstetric surgery in pregnancy.

Unlabelled: Fetal phonocardiography is a well-known auscultation technique for evaluation of fetal health. However, murmurs that are synchronous with the maternal heartbeat can often be heard while listening to fetal heart sounds. Maternal placental murmurs (MPM) could be used to detect maternal cardiovascular and placental abnormalities, but the recorded MPMs are often contaminated by ambient interference and noise.

Background: During electronic fetal monitoring, the positions provided to mothers by perinatal nurses and midwives are essential for ensuring maternal comfort, as well as maternal and fetal well-being. This study aimed to investigate the impact of various maternal positions during electronic fetal monitoring on maternal and fetal health.
Methods: This study was conducted in a randomized controlled trial design.

Thrombosis is an important cause of morbidity and mortality worldwide. Pregnancy is a hypercoagulable state, and thrombotic complications in pregnancy are a major cause of maternal and fetal morbidity and mortality. Current guidelines support the selective use of aspirin, heparin, and warfarin in pregnant women.

Congenital heart defects (CHDs) are the most common congenital defect, occurring in approximately 1 in 100 live births and being a leading cause of perinatal morbidity and mortality. Of note, approximately 25% of these defects are classified as critical, requiring immediate postnatal care by pediatric cardiology and neonatal cardiac surgery teams. Consequently, early and accurate diagnosis of CHD is key to proper prenatal and postnatal monitoring in a tertiary care setting.
