Abstract

FIELD: obstetrics. The goal is to reduce the number of complications of the mother and fetus. To do this, the sacral and suprapubic regions are affected by an electromic current, in the presence of intense, painful contractions in the background of the opening of the cervix from 2 to 6 cm, pulses with an amplitude of 6-24 mA, duration of 0.25 ms, frequency of 15-30 Hz are applied. 0.5-2 hours; in the presence of premature pouring of amniotic fluid, the absence of contractions and the immature cervix, impulses with an amplitude of 6-24 mA, a duration of 0.25 ms, a frequency of 100-120 Hz are performed for 2-4 hours. This allows you to adjust the clan activity in preterm normalize the process of childbirth, which helps to improve the state of the mother and fetus, reduce their complications and reduce perinatal mortality.

Description

This invention relates to medicine, namely obstetrics.

The aim of the invention is to reduce the number of complications of the mother and fetus in the management of preterm labor.

The method is implemented as follows.

The skin of the pregnant woman at the place of application of the electrodes, the suprapubic and sacral areas, is treated with alcohol, then two lead electrodes 60 x 80 and 30 x 100 mm in size, embedded in flannel moistened with saline, fixed to the skin with special rubber foam and connected to the source a current generating bipolar, asymmetrical rectangular pulses with a duration of 0.25 ms, a frequency of 15–30 Hz with a current intensity of 6–24 mA with a spontaneous development of excessive labor. Before exposure, the pain threshold is determined, i.e. the strength of the current at which the patient begins to feel goosebumps, tingling or tingling under the electrodes: as the current adapts to the current, these sensations weaken, in such cases the magnitude of the supplied current increases, thus achieving a constant sensation under the electrodes. The impact on pregnant women is carried out within 0.5-2 hours.

With prenatal rupture of amniotic fluid and premature pregnancy, impulses with a duration of 0.25 ms and a frequency of 100–120 Hz with a current intensity of 6–24 mA are applied against the background of an immature cervix of the uterus. The duration of exposure depends on the initial state of the cervix: with an immature neck, the procedure lasts at least 4 hours, with a ripening neck 2-4 hours.

Example 1. Pregnant S. Diagnosis: pregnancy - 28 weeks, childbirth I, headache previa, prenatal rupture of amniotic fluid. On admission, sharply painful contractions were noted, prolongedON O O h4

00

at short intervals, during which the uterus remains in the hypertonus. During a vaginal examination: the cervix is shortened, too thick, the external pharynx hardly passes the finger. Due to the inconsistency of the nature of the clan activity and the state of the cervix, a transcutaneous stimulus was performed using the following procedure: through two lead electrodes of GO 80 and 30 100 mm in size, attached to the skin of the suprapubic and sacral regions and connected to the pulse generator current, bipolar rym asymmetric rectangular pulses with a duration of 0.25 ms, a frequency of 15 Hz. After determining the threshold current at which the patient had a tingling sensation under the electrodes, the magnitude of the applied current was increased from 6 to 24 mA. After 20 minutes from the start of the procedure, the painfulness and duration of contractions decreased, the uterus tone outside the contractions normalized. The duration of the procedure is 2 hours. At the control v vaginal examination: the cervix is dimpled, soft, of moderate thickness, the opening is 4 hours. In the future, labor activity progressed dedekazhno with cervical dilatation. After that, the childbirth proceeded without any complications with the birth of a living fetus, august sex weighing 980 g. The total duration of labor was 5 hours and 55 minutes.

Example 2, Pregnant B. Diagnosis: pregnancy II — 32 weeks, head pretension, prenatal rupture of amniotic fluid, long anhydrous period (72 hours). When examining the patient, short irregular contractions are noted, the uterus of the contractions remains in the hypertonus, Vaginal examination showed that the cervix is in the stage of ripening, mild, open. A trans-electrostimulation was performed, impacted by bipolar asymmetric rectangular pulses with a duration of 0.25 ms, a frequency of 100 Hz, and an amplitude of 24 mA. After 1 h from the start of the procedure, a regular labor was active, with a vaginal control test - the cervix was smoothed, soft, opening 2-3 cm. The rest of the birth was without complications, the birth ended with the birth of a live premature baby, later transferred to a child department at the nth nursing stage. Total duration of labor 4 hours 55 minutes

Example 3. Pregnant, Diagnosis: pregnancy - 35 weeks., Childbirth II, prenatal

water of amniotic fluid, anhydrous

interval 13 h. Upon examination of the patient

no generic activity; vaginal is. following showed that the cervix is up to 2 cm long, soft, we pass a canal for a finger. In order to reduce the risk of complications in the mother and the fetus, percutaneous electrostimulation was performed: impacted by bipolar asymmetrical rectangular pulses of 25 ms duration, 120 Hz frequency, amplitude 24 mA. After 2 hours from the onset of exposure, rare, short, irregular contractions occurred. The duration of the procedure is 4 hours. 2 hours after the procedure has been completed, a regular generic activity has developed. At the control vaginal examination: the cervix was smoothed, the specks were thick, soft, open 2 cm. The subsequent birth parentage proceeded without complications, the childbirth ended with the birth of a live child who was discharged home for 7 days. Total duration of labor 3 h 05 min.

Example 4. Pregnant. Diagnosis:

5 pregnancy IV-34 weeks., Childbirth, headache presentation. On admission, sharply painful, intense contractions were noted, no water poured out. Vaginal examination revealed smoothness of the cervix of the cervix, opening of 5-6 cm, fetal bladder - after the inspection, it was made completely by amiota, light waters poured out in moderate quantities. In connection with a sharp disease and excessive intensity of the skaz5 current {4-5 for 10 min), in order to reduce complications for the mother and the fetus, percutaneous electroneurostimulation was performed according to the following procedure: through two lead electrodes of 80 and 30 mm and 100 mm in size

0 attached to the skin of the suprapubic and sacral areas and connected to the pulse current generator, affected by bipolar, asymmetric rectangular pulses - duration of 0.25 ms,

5, the frequency of pulses sending was 300 Hz, the current strength after determining the pain threshold was increased from 6 to 18 mA. After 20 minutes from the start of the procedure, the pain and intensity of contractions decreased. The tone of the uterus outside the skv0 current is normalized. Duration of the procedure is 30 minutes. At the control internal study: the neck is smoothed, the opening is 6-7 cm. After 1 h after the end of the procedure, the birth ended in birth

5 boys weighing 2,350 gr. Total duration of labor 4 hours 55 minutes.

Example 5. Pregnant, Diagnosis: pregnancy I - 35 weeks. prenatal rupture of the amniotic fluid, an interval of 16 hours. Hormonal background was created, it was decided to carry out further labor induction using percutaneous electroneurostimulation. A vaginal examination performed before the procedure showed that the cervix is shortened to 1.5 cm, it is softer, the channel passes for one transverse finger. Percutaneous electrosystroke stimulation was carried out according to the above described method: through two lead electrodes attached to the skin of the suprapubic and sacral areas and connected to the pulse current generator, they were applied to bipolar, asymmetric, 0.25 ms pulses with a frequency of 120 Hz , current 6-18 mA. The duration of the procedure was 4 hours. By the end of the procedure, rhythmic contractions of the uterus appeared. half an hour after

the end of the procedure, the procreative activity has developed. Further

childbirth without complications, the total duration is 8 h 10 m. The live boy was born weighing 2200 g,
