Novel Insights In presence of cardiotocographic features suspected for hypoxic insult, intrapartum ultrasound in the hands of experienced operators can demonstrate cerebral edema as an indirect sign of fetal hypoxia affecting the fetal CNS and exclude non-hypoxic conditions potentially leading to abnormalities of the fetal heart rate. Introduction Hypoxic-ischemic encephalopathy is a syndrome involving the fetal central nervous system as the result of a perinatal hypoxic-ischemic injury. To date, transfontanellar ultrasound represents the first line exam in neonates with clinical suspicion of HIE as it allows to show features indicating acute hypoxic injury and exclude potential non-hypoxic determinants of HIE, however there is no report concerning the sonographic assessment of the brain during labor.

Objective: To evaluate whether, in late pregnancy, the cerebral Doppler can identify very small fetuses that are less likely to experience intrapartum compromise (IC).
Material And Methods: This was a retrospective study of 282 singleton pregnancies that underwent an ultrasound scan at 32 + 0- 40 + 6 weeks and were delivered after induction, or spontaneous onset of labor. Very small fetuses were defined as fetuses with estimated weight less than the 3rd centile.
The role of intrapartum ultrasound combined with free position delivery in the management of abnormal fetal positions during labor.

Objective: To investigate the effectiveness of combining intrapartum ultrasound with free maternal positions in managing abnormal labor, specifically focusing on its impact on delivery outcomes.
Methods: A retrospective cohort study was conducted on 176 cases of abnormal labor progression in women who attempted vaginal delivery at our hospital from June 2021 to May 2022. Among these, 88 cases were diagnosed with abnormal fetal positions using a combination of intrapartum ultrasound and vaginal examination, and these patients were guided to adopt free maternal positions (experimental group).

Aims: Ultrasound is used in the delivery room to assess fetal head position, engagement during labor, and anal sphincter injuries in the immediate postpartum period. The transperineal approach allows for direct visualization of the structures of interest without altering anatomical landmarks. Various ultrasound measurements during labor have been described in the literature, and their use varies widely across maternity units.

Amniotic fluid assessment is crucial in prenatal ultrasound to monitor fetal conditions, with polyhydramnios, characterized by excessive amniotic fluid, affecting 1%-2% of pregnancies. Polyhydramnios is linked to complications such as placental abruption, preterm labor, congenital anomalies, and postpartum hemorrhage, emphasizing the need for early detection and management. While idiopathic causes account for 60%-70% of cases, other causes include impaired fetal swallowing and increased urine production due to maternal, fetal, and placental conditions.
