20. Obstetrical twist

obstetric turn - an operation that allows you to change the unfavorable (transverse, oblique, pelvic) position of the fetus for the course of childbirth to a favorable (longitudinal) one.

External rotation of the fetus is performed after the 35th week of pregnancy using external techniques. This effect is only through the abdominal wall without manipulation in the vagina. External rotation is indicated for transverse and oblique positions of the fetus, with breech presentations. Exposure can be carried out in the presence of good fetal mobility, normal size of the pelvis or its slight narrowing (true conjugate of at least 8 cm), in the absence of fetal hypoxia, premature detachment of the placenta, i.e., a quick end of labor is not indicated.

External rotation for repeated pregnancies can be performed without general anesthesia.

With a transverse and persistent oblique position of the fetus, special external techniques are used to rotate. It is first necessary to prepare a woman in labor: remove urine, inject a 1% solution of promedol (1,0 ml) subcutaneously, lay her on a hard couch on her back with legs slightly bent, drawn to her stomach. The obstetrician sits down on the side of the pregnant woman, puts both hands on her stomach, and one of his hands rests on the head, clasping it from above, and the other on the underlying buttock of the fetus. Then, clasping the fetus with one hand, put pressure on its head towards the entrance to the small pelvis. The other hand pushes the pelvic end up to the bottom of the uterus. With pelvic presentation of the fetus at 29-34 weeks, a set of special physical exercises is carried out, the purpose of which is to correct the position of the fetus. If the effect of the ongoing exercises has not come, an attempt at 35-36 weeks in the hospital for an operation of external rotation of the fetus on the head is possible. It is called preventive turn. It is done according to the general rules: the buttocks of the fetus are shifted towards the back, the back towards the head, and the head is directed towards the entrance to the small pelvis. After the rotation, systematic monitoring of the condition of the pregnant woman is necessary. Recently, the implementation of a preventive rotation has been disputed.

When carrying out an external rotation, complications of the following nature are possible: fetal hypoxia, premature detachment of the placenta.

External-internal classic rotation is performed by a gynecologist, in emergency situations it can be performed by an obstetrician. When it is carried out, one hand is inserted into the uterus, the other is placed on the stomach. When carrying out the external-internal classical rotation, the fetus must be turned on the leg. The indications for the external-internal classical rotation of the fetus on the leg include the transverse position of the fetus and extensor head presentations that are dangerous for the mother (for example, frontal). As a rule, the operation is performed with a dead fetus, in the presence of a live fetus, a caesarean section is preferable.

To carry out the external-internal classical rotation, the necessary condition is the complete opening of the uterine os and the full mobility of the fetus.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Augmented Reality Contact Lenses 12.04.2022

California-based company Mojo Vision has created a new prototype contact lens with augmented reality technology. After reworking the electronics and changing the power supply, the engineers prepared the device for testing. The first software and user interface was also developed.

The company unveiled its first prototype two years ago, when engineers managed to create a display, an oxygen saturation system, a microchip and energy management tools, and developed eye-tracking algorithms. Even then, the lenses looked like ordinary cosmetic contact lenses that change the color of the eyes, although they hid a whole computer with tiny displays, batteries and more.

Since then, Mojo Vision has invested in lens software development, created the underlying operating system code, and created the first user interface components. This software opens up the possibility of further development and testing of various lens usage scenarios by consumers and businesses.

The electronic filling of the lenses is located on a rigid gas-permeable plastic, unlike the material from which ordinary contact lenses are made. Miniature devices include accelerometers, gyroscopes, a magnetometer, and radio communications. In addition, there is a microchip for power management, an image sensor and a microprocessor.

One of the main differences between the new prototype and the one that was presented in 2020 is the rejection of power transmission over a wireless connection in favor of a battery, since inductive coupling did not provide uninterrupted power.

Initially, the company identified as its target group people with low vision, for whom the lenses will help to better see road signs and other necessary information. As well as athletes for whom it is important to receive up-to-date information without being distracted from the race or match. But while the developers are not ready to talk about Mojo Lens as a product - in the coming years, the device will be optimized, debugging applications and testing, which will show who the first customers of the company will be.
