RU2014100C1 - Method of treating fetus hypoxy - Google Patents

Abstract

FIELD: medicine. SUBSTANCE: new method prescribes administering medicamentous preparations and treating lumbar region of pregnant female by pencils of electric current impulses with periodically changing basic frequency of pulse clusters according to linear law within range of 50 to 250 kHz and synchronizing basic frequency variation with pulse cluster repetition period in such a manner that basic frequency variation will account for 20 to 25 kHz over pulse cluster repetition period. EFFECT: improvement of uterine-placental and fetal-placental blood circulation.

Description

 The invention relates to medicine / and more particularly to obstetrics and gynecology / and can be used to treat intrauterine hypoxia of the fetus / pelvic inflammatory diseases / in the treatment of miscarriage.

 Known drug methods for the treatment of fetal hypoxia.

 The disadvantage of these methods is the undesirable side effects of drugs / allergic reactions.

 Non-drug methods of treatment / associated with the influence of physical factors on internal tissues are also known.

 The disadvantage of these methods are limited functionality and low efficiency.

 The closest in essence is the method / based on the use of diadynamic therapy / consisting in the fact that the treatment is carried out by applying electrodes to the skin in the projection of the pelvic organs and on the lumbar region and is exposed to currents in the mode of constant current and packs of half-sinusoidal pulses with a prolonged trailing edge with a frequency repetition of 50 or 100 Hz and a duration of 10 or 5 ms [1].

 The disadvantage of this method is the low efficiency / as well as the appearance of discomfort during the procedure.

 The purpose of the invention is the improvement of uteroplacental and placental circulation.

 The goal is achieved by the fact that they additionally act on the lumbar region of matter by packs of pulses of electric current / while periodically adjusting the frequency of filling of the packs of pulses according to a linear law in the range from 50-250 kHz and synchronizing the change in the frequency of filling with the repetition period of the packs so that during the repetition period the filling frequency was 20-25 kHz.

 The proposed method for the treatment of fetal hypoxia differs from the known methods in that / periodically a coincidence of the frequency of filling of the pulse packets with the optimal frequency / at which the best penetration of the current to the neuromuscular structures occurs / causing the effect of vasodilation. As a result, there is a rapid achievement of the effect of increased blood flow and its stabilization during the exposure time.

 Example 1. A mother of E. (birth history N 491/422) was admitted on 2.20.3.02.87 to the maternity hospital N 3 of the city of Kuibyshev 1 hour after the outflow of amniotic fluid without labor. The first pregnancy / for a period of 39 weeks / proceeded without complications. The position of the fetus is longitudinal / the head is pressed to the entrance to the small pelvis. Fetal tones are clear / rhythmic / 134 beats / min. For the purpose of labor induction, the dropwise administration of 2 ml of a 5% solution of prostenone in 400 ml of a 5% glucose solution was started at a rate of 14 drops in 1 min. At 700, regular labor began / fetal tones remain clear / rhythmic / 140 beats / min.

 At 11.00, there were contractions of the type of an ascending gradient. The fetal head is pressed to the entrance to the pelvis / the fetal heart rate became muffled / increased in frequency to 160 beats / min. Light amniotic fluid is leaking.

 During vaginal examination, the cervix is smoothed / its edges are thick. Opening of the uterine pharynx 2 cm. The head is pressed to the entrance to the small pelvis. The cape is unattainable. Diagnosis: 1 period of labor. Discoordinated activity. Anhydrous period 10. started intrauterine hypoxia of the fetus. Treatment: 5 ml of baralgin / 2 ml of noshpa / 4 ml of cigetin / 20 ml of a 20% glucose solution were injected into a vein. Due to the lack of the effect of the treatment of discoordinated labor and taking into account the progressing intrauterine hypoxia of the fetus, it was decided to terminate the delivery by cesarean section.

 To improve the condition of the fetus in the order of anesthesia preparation, the treatment was started according to the proposed method: electrodes were applied to the patient’s skin / were applied by packs of pulses of electric current with a duration of 300 μs / amplitude of 50 mA / repetition rate of 150 Hz / periodically changed the frequency of filling of the packs of pulses in the range of 50- 250 kHz according to the linear law / at the same time, the change in the filling frequency was synchronized so that for the period following the change in the filling frequency it was 25 kHz.

3 minutes after the start of treatment with the proposed method, the disappearance of discoordinated labor / a significant improvement in the auscultatory picture of fetal heartbeats was noted: the disappearance of arrhythmias / tones became clear / their frequency was 140 beats / min. Treatment with the proposed method was carried out for 20 minutes until the fetus was removed after the woman in labor was anesthetized and the operation started / proceeded without complications. The child is removed in a satisfactory condition. The Apgar score is 8 points (2 + 2 + 1 + 1 + 2 = 8). Indicators of KShchS: in blood from an umbilical cord vein pH 7.30, pCO ₂ 40.3 bHg / BE = -14/8 mmol / l; in blood from the umbilical artery, pH = 7/06, pCO ₂ = 48.6 mm Hg / BE = - 15/4 mmol / L.

 Thus / it was possible to quickly achieve a significant improvement in blood flow in the uterus and to achieve a beneficial effect on the part of the fetus. Indicators of acid-base balance of his blood indicate metabolic acidosis as a result of intrauterine hypoxia.

 The proposed method of treatment was used in 23 births / where signs of acute and chronic intrauterine fetal hypoxia / caused by toxicosis of pregnant women / weak labor activity / premature detachment of a normally located placenta / drug-related illness of a pregnant woman were noted. In 20 observations, a favorable therapeutic effect that quickly occurred (within 3-6 minutes) was noted / persisted until the delivery was completed. Assessment of the health status of newborns on an Apgar scale of 8-9 points.

 In three cases (premature detachment of a normally located placenta / tight cord entanglement) / after application of the proposed method, a temporary improvement was noted / childbirth was completed operatively. Assessment of the condition of newborns 6-7 points.

Claims (1)
