The invention relates to medicine, in particular to a method of radiation imaging position of the needle in the epidural space when performing epidural analgesia, and epidural anesthesia.

Epidural injection of anesthetics at the lumbar level known since 1901. In addition to purely anesthetic problems, epidural blockade is one of the most effective ways of relieving pain with herniated intervertebral discs. (R.K. Sharma: Indications, technique and results of caudal epidural injection for lumbar disc retropulsion. Postgraduate Medical Journal (January 1977) 53, 1-6.)

However, many authors have noted that the herniated disc may provoke inflammation around him, thereby leading to the development of irritation of the spine and help maintain back pain. Thus, it is logical epidural injection of corticosteroids. (J.W. Lee, H.I. Shin, S.Y. Park, G.Y. Lee, H.S. Kang: Therapeutic Trial of Fluoroscopic Interlaminar Epidural Steroid Injection for Axial Low Back Pain: Effectiveness and Outcome Predictors. AJNR Am J Neuroradiol 31:1817-23 (Nov-Dec 2010)), the blockade as the Sacro-epidural and epidural traditionally performed blindly, i.e. without the use of radiological methods for monitoring the progress of the Toolkit. But when the variability of the thickness of the epidural space often is the puncture of the Dura. Literature data indicate that a significant number (up to 25-30%) so the x situations, as the correct position of the needle in the epidural blockade even in the hands of experienced physicians. A well-studied potential complications after subarachnoid injection of glucocorticosteroids is the development of arachnoiditis. (Blake A. Johnson, Kurt P. Schellhas, and Steven R. Pollei: Epidurography and Therapeutic Epidural Injections: Technical Considerations and Experience with 5334 Cases. AJNR Am J Neuroradiol 20:697-705, April 1999.)

Currently, to solve these problems is used fluoroscopically or CT control for this procedure. (el-Khoury GY, Ehara S, Weinstein JN, et al: Epidural steroid injection: a procedure ideally performed with fluoroscopic control. Radiology 1988; 168:554-557.)

However, this method is rather time-consuming and incurs significant dose radiation exposure for the patient and for the doctor performing the procedure.

The closest to the technical essence and the achieved effect and selected as a prototype is a method of ultrasonic navigation when performing spinal anaesthesia. (Chin KJ, Chan VW, Ramlogan R, Perlas A: Real-time ultrasound-guided spinal anesthesia in patients with a challenging spinal anatomy: Two case reports. Acta Anaesthesiol Scand 2010; 54:252-5) in which the needle from intralaminar access is available at Dura.

The main disadvantage of this method is the small width of the posterior epidural space, complicating the positioning of the needle tip in it until the puncture of the Dura.

Task this is part II of the invention is to develop a method of controlling the position of the needle in the posterior epidural space.

The technical result is the ability to accurately identify the location of the needle in the epidural space using widely available deprived dose radiation exposure ultrasonic method of navigation.

This task is realized due to the fact that in the known method of controlling the position of the needle in the posterior epidural space when performing epidural blockade, according to the invention, the introduction of a needle carried out under control of the ultrasonic scanning of the paravertebral oblique access, however as a guideline use the movement of the Dura forward from the tip of the needle and extending posterior epidural space with the introduction of the prepared solution.

Studies on patents and scientific and technical information sources showed that the proposed method is unknown and should not be explicitly studied the prior art, i.e meets the criteria of "novelty" and "inventive step".

The proposed method can be applied in any medical institution, provided with an ultrasonic device operating in b-mode real-time, therefore, practically applicable".

The claimed method is as follows:

Blockade perform in the conditions of the treatment room in situation the AI of the patient lying on the stomach with the use of ultrasound scanner with electronic convex probe with frequency range from 2.0 to 5.0 MHz. The operating frequency for each case determine the depth-dependent constitutional features of the patient. The sensor is applied ultrasonic gel and top to wear sterile protective cover. Followed the rules of asepsis and antisepsis. To fill the space between the skin and the sensor used disinfectant solution, such as solution Andes. Under the patient's stomach enclose a small cushion to reduce the severity of lumbar lordosis. First, the sensor is installed in the sagittal oblique position next to the spinous processes on the affected side for visualization Midwich intervals to counting vertebrae. The benchmark for this is the image of the sacrum in the form of a continuous reflective line with acoustic shadow behind her. After counting the vertebrae and Refine, if necessary, the level of the lesion (in fact rendering of the specified position of contraction or deformation of the dural SAC on interest level), mark the point of injection near the sensor on a site that allows you to visualize the progress of the needle. Conduct intradermal anesthesia point vcol needle and subcutaneous anesthesia with 0.5% solution of novocaine in an amount of about 10 ml Through the planned point vcol impose a special puncture needle with the rendered ultrasound tagged on to the Chica, diameter 18 G. Compare the direction of insertion of the needle to the plane of the sensor. After puncture of the subcutaneous fascia needle on the screen of the ultrasound scanner has a clear visualization. To further clarify the location of the needle tip in doubtful cases it is possible periodic introduction of a small amount of 0.5% solution of novocaine. With the passage of the needle through the yellow ligament of the piston of the syringe is stiff. At the end of the passage of the needle through the yellow ligament is typically "failure", when this is rendered the tip of the needle in the epidural space, before hyperechoic Dura mater. An additional criterion, which suggests finding the needle in the epidural space, is the reduction of the resistance of the piston of the syringe. Then introduce the mixture, usually containing, respectively, the standard recommendations, 3 ml of anesthetic solution, for example of 0.5% lidocaine, and 2.0 ml of corticosteroid, such as flosteron. With its introduction of the Dura under the current fluid is moving forward from the tip of the needle, and is displayed on the rear extension of the epidural space in the form of additional hypoechoic area between the inner contour of the yellow ligament and the Dura mater. Clinical examples:

Patient I., 54, was admitted to the hospital with complaints of pain in explain the Noi region with irradiation in the left leg, data pain concerned within 5 days. In the neurological examination revealed pronounced state-vertebral syndrome, numbness in the L5 dermatome of the spine to the left, the weakness of the thumb to the left, positive symptom Lasaga left. MRI revealed a median hernia at the level of L4-L5 4,5 mm figure 1 are given the image of the back of the epidural space prior to the blockade, figure 2 image of the rear extension of the epidural space at the level of L4-L5 after conducting epidural blockade. The next day, the patient noted a significant decrease in back pain, recovered strength in the thumb.

Patient P., 48 years old, was admitted to the hospital complaining of back pain with irradiation to the left leg. In the neurological examination revealed numbness in the L5 dermatome, S1 left, loss of Achilles reflex on the left. On MRI revealed paramedian disc herniation on the left size of 5 mm was performed epidural blockade at the level L4-L5 on the left (figure 3) After 10 minutes after the blockade, the patient noted a significant decrease in back pain. The next day when the examination of complaints about back pain has significantly decreased, Achilles reflexes become symmetrical.

Patient M., 48 years old, was admitted to the hospital complaining of severe pains in the back with irradiation to the left leg. In the neurological examination revealed syndrome compression of the S1 nerve root text by the VA. On MRI revealed paramedian hernia L5-S1 on the left to 6 mm patients received epidural blockade at the level of L5-S1 on the left (figure 4) On the next day after the blockade, the patient noted a significant decrease in back pain, hypesthesia in the area of innervation of S1 on the left denies, increased ankle reflex on the left.

The method of controlling the position of the needle in the posterior epidural space when performing epidural blockade, characterized in that the introduction of needle carried out under control of the ultrasonic scanning of the paravertebral oblique access, however as a guideline use the movement of the Dura forward from the tip of the needle and extending posterior epidural space with the introduction of the prepared solution.

SUBSTANCE: invention refers to medicine, namely to anaesthesiology, and may be used as an anaesthesia care of a surgical intervention for carotid endaterectomy or internal carotid artery resection after pathological deformation thereof. That is ensured by general anaesthesia in a combination with deep and superficial cervical plexus blockade. Pre-medication is used the day before the operation and on the operative day in the morning. Diazepam is introduced intramuscularly 30 minutes before the operation in a combination with phentanyl; the introduction is followed by ECG monitoring and heart rate count, plethysmography with arterial blood saturation, non-invasive blood pressure measurement and neuromonitring according to a bispectral index or entropy. Catheterisation of patient's peripheral or central vein is followed by an infusion therapy, an ionotropic therapy, a cardiotropic therapy, peripheral resistance maintenance. If heart rate is no more than 80 beats per minute, the anaesthesia is induced to reach an anaesthetic depth according to the bispectral index or entropy within 40-60 units. Analgesia is provided by the intravenous introduction of 0.005% phentanyl; myoplegia is ensured by the intravenous introduction of a myorelaxant. After tracheal intubation, the patient is transferred to forced volumentic artificial pulmonary ventilation with the CO2 level within 35-45 mm Hg according to capnography. The anaesthesia is maintained by supplying an inhalation anaesthetic to the steam level of 0.8-1.0 MAK 0.8-0.9 litre of the air and oxygen flow containing 50% oxygen with controlling the inhalation anaesthetic volume by the level of the anaesthetic depth according to the bispectral index or entropy. That is followed by deep cervical plexus blockade. A tubercle of the VI cervical vertebra (a carotid tubercle) and a mastoid process are localised; thereafter a line connecting the above reference points is drawn on skin. The second line is drawn 1 cm below the first one in parallel. To verify an injection point of a local anaesthetic, the spines of IV, III, II cervical vertebras being at 1.5 cm from each other are palpated, and the reference point is the VI cervical vertebra. The needle is inserted perpendicularly to the skin and slightly in the caudal direction to reach the spines. The anaesthetic is introduced in a dose of 5-7 ml in each point C4, C3, C2. Another 5-7 ml of the anaesthetic is introduced in a point found in an apex of the mastoid process. The superficial cervical plexus blockade requires introducing he fan-shaped introduction of the anaesthetic solution in a dose of 15 ml in a point found in the middle of a lateral crus of the nodding muscle under the above muscle, 4-5 ml in each direction from the same point; the first and following injections are performed at a depth of a usual intramuscular needle perpendicularly to nodding muscle.

SUBSTANCE: invention refers to medicine, namely to obstetrics and gynaecology, and can be used in delivery. That is ensured by localising predominantly a placenta in the uterus and a place of umbilical cord attachment with an ultrasound detector in a projection of the above place on a woman's stomach. A foetus image is visualised simultaneously with the uterus and placenta under the detector in a cross section with a front or side the predominant localisation of the placenta in the uterus. The detector is fixed, and dynamics of foetus's physical activity, uterine wall thickness, ultrasonic echogenicity of the uterus, placenta, thickness of their blood vessels and pulsation amplitude are controlled continuously. If observing constant thickness and ultrasonic echogenicity of the uterus and placenta, thickness and pulsation amplitude of their vessels and continuous weak contraction and relaxation of the muscular groups of all foetus's body parts that are represented by image vibrations on the screen, the foetus's condition is considered to be good with no labours. If observing regular reductions of the thickness of uterine walls, vessel and pulsation amplitude, ultrasonic echogenicity of the uterus and placenta coinciding with the periods of a foetus's rest in a position with legs and arms pressed tightly to the body and with hands clenched, an excellent foetus resistance to hypoxia in labour is stated. If the foetus shows respiratory rib movements, multiple flexion-extension movement of the limbs and opening hands before the period of reduction of uterine wall thickness, ultrasonic echogenicity of the uterus and placenta, thickness and pulsation amplitude of the blood vessels is completed, the length of the rest period is started with the above period. If the length tends to zero testifies to bad foetus resistance to hypoxia in labour.

EFFECT: method provides the well-timed preparation of the pregnant woman fort the delivery by improving accuracy and safety of detecting uterine and placental ischemia periods and assessing the foetus's state under the conditions preventing the uncontrolled intensification of the hypoxic foetus involvement.

SUBSTANCE: invention relates to medicine, namely to obstetrics and gynecology, and can be used in obstetric aid in case of intrauterine hypoxia of fetus and asphyxia of newborn baby. For this purpose US examination of skin of finger-pads of fetus during birth pangs and in breaks between them is performed. Unchanged ultrasonic echogenicity of skin of finger-pads is estimated as good adaptation of fetus to hypoxia in labour and labour is managed in accordance with general rules. Reduction of ultrasonic echogenicity of skin of finger-pads in labour testifies to presence of acrocyanosis in fetus. In this case woman in childbirth is asked to start deep and frequent breathing. If the woman is unconscious, artificial hyperventilation of lungs with breathing gas is carried out up to appearance of first symptoms of oxygen poisoning in the woman, with continuation of hyperventilation until lung respiration in the newborn baby begins and umbilical cord is cut. State of the newborn baby's health is performed by means of thermovision camera. Analysis of the newborn baby's thermal radiation intensity by means of thermovision camera is started simultaneously with beginning of its body contact with atmospheric air. Birth of newborn baby with normal temperature testifies to absence of cyanosis in it. In this case labour is finished in accordance with general rules. Identification of section of local hypothermia in newborn baby's skin testifies to cyanosis and acrocyanosis. In case if newborn baby after its birth does not breath independently, after removal of content of airways and appearance of local hypothermia of skin in peripheral sections of newborn baby's body, its reanimation is started by interrupted double compression of chest. Reanimation is stopped when newborn baby starts crying and chest starts to perform respiratory movements. If baby is immobile, respiratory mask, connected with breathing apparatus is applied on its face, and artificial lung ventilation is carried out by them. When temperature in zone of local hypothermia increases, umbilical cord is clipped and dissected.
