The hypoxia of a fruit is the insufficient receipt to an oxygen fruit connected with diseases of mother, violations of a uterine and placentary or funic blood-groove, diseases of the child. Diagnosis of a hypoxia is based on direct assessment of a condition of a fruit and the analysis of results of indirect methods.
It is required to you
- - observation of stirs of a fruit;
- - listening of heartbeat by means of a stethoscope;
- - kardiotokografiya;
- - doplerometriya;
- - amnioskopiya.
Instruction
1. If you noticed changes in physical activity of a fruit, it can be symptom of a hypoxia. In an initial stage you can find the uneasy behavior of the child which is expressed in increase and strengthening of its stirs. At an acute shortage of oxygen and increase of a hypoxia of the movement of a fruit begin to weaken.
2. Surely tell the doctor observing you about changes of stirs. He by means of a stethoscope will listen heartbeat of a fruit, will estimate the heart rate, a rhythm, existence of noise. But such method will be able to reveal only rough changes more often arising at a sharp hypoxia. The doctor can also suspect a chronic hypoxia on indirect signs, such as reduction of height of standing of a bottom of a uterus connected with a fruit growth inhibition and lack of water.
3. At suspicion of a hypoxia to you will appoint a kardiotokografiya (KTG). This research is successfully conducted in polyclinic conditions. By means of elastic thongs on a stomach of the pregnant woman the ultrasonic sensor which is fixed in the place of listening of heartbeat of a fruit fastens. Frequency of increase and an urezheniye of warm reductions has diagnostic value. If increase of warm reductions is the response to the movement of a fruit or reductions of a uterus (not less than 5 in 30 minutes), then it is possible to speak about a safe condition of a fruit. For this purpose within KTG not stressful test which essence consists in emergence of uchashcheniye of serdtsebiyeniye in response to movements of the child or reduction of a uterus is carried out. If does not yield a fruit any reaction, it allows to speak about a hypoxia.
4. By means of a dopplerometriya the blood-groove research in vessels of a uterus, umbilical cord and fruit is conducted. In the presence of violations in blood circulation, it is possible to estimate degree of severity of a hypoxia and to take measures for the further safe course of pregnancy. The first research is recommended in 16-20 weeks of pregnancy as, since this term pathological violations of a blood-groove are possible.
5. For the purpose of diagnosis of a hypoxia at the child are estimated insufficiency existence in amniotic waters of meconium - a fruit calla testifies. Its hit in waters is connected with violation of blood circulation in intestines owing to a hypoxia. There is a relaxation of a sphincter of a rectum of a fruit and meconium gets to amniotic waters. By means of an amnioskopiya it is examined by the optical device via the cervical channel of amniotic waters. This method is more often applied just before childbirth.
