Objective: To evaluate the safety and perinatal outcomes of thoracoamniotic shunting in the treatment of fetuses with severe primary hydrothorax. Methods: 22 cases of suspected severe primary fetal hydrothorax which underwent thoraco-amniotic shunting in Shanghai First Maternity and Infant Hospital, Fetal Medicine Unit and Prenatal Diagnosis Center from January 2012 to December 2017 were analyzed retrospectively. Hydrothorax associated with structural or chromosomal abnormalities, infections and immune fetal hydrops were excluded. Results: Totally, 28 shunts were placed in 22 fetuses. The median gestational age at TAS was 31.3 weeks. Preterm membrane rupture within 7 days after the procedure occurred in 9.1% (2/22) cases. Catheter displacement occurred in 18% (4/22) cases. The interval from shunting to delivery was 26.0 days. One fetus ended in induced abortion; 21 (95%, 21/22) babies were born alive, and their median gestational age at delivery was 34.4 weeks. 62% (13/21) newborns required ventilator supports; 4 neonatal deaths were attributed to pulmonary hypoplasia. The overall perinatal survival rate was 81% (17/21) . The perinatal survival rate with hydrops and without hydrops were 10/13 and 7/8 respectively. Conclusion: Thoraco-amniotic shunting is a safe procedure for intrauterine therapy and could improve the perinatal outcomes of severe primary fetal hydrothorax.

Shunt Admittances01:26

Shunt Admittances

Shunt admittances play a crucial role in the analysis of transmission lines, particularly for three-phase systems with neutral conductors. When a uniformly charged conductor is positioned above the Earth, it induces an equal but opposite charge on its surface. This interaction creates electric field lines between the conductor and the Earth.
To model this effect, the method of images is employed. This method involves replacing the Earth with an image conductor that mirrors the original...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

Primary Active Transport01:47

Primary Active Transport

In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...
