Anomalies of patrimonial activity. To their basic kinds carry delicacy of patrimonial activity, excessively strong patrimonial activity.

Delicacy of patrimonial activity is characterized by a failure of force and duration of reductions of a myometrium, augmentation of pauses between fights. Distinguish primary and secondary patrimonial delicacy. Primary delicacy arises in the beginning of a childbed and can, proceed both in II, and in III period of sorts. Secondary delicacy develops on a background of normal fights in I or II period of sorts. The reasons of primary delicacy of patrimonial activity: an overstrain of function of the central nervous system, an endocrinopathy, preceded frustration of a menstrual cycle, an infantilism, disturbances of a metabolism, developmental anomalies of a uterus, inflammatory processes in genitals, a strong stretching of a uterus (a hydramnion, a multiple pregnancy, a large fetus), advanced age travailling. Development of primary delicacy of fights is promoted by an antenatal pouring out of amniotic waters. The reasons of secondary patrimonial delicacy, besides specified above, - fatigue of the parturient woman in sorts, clinically narrow basin, cross-section position of a fetus, a fetal presentation, a rigidity of passage of a uterus, unsystematic purpose of the preparations stimulating labors. Delicacy of patrimonial activity is expressed in a shorting of fights (or attempts) and augmentation of pauses between them. It leads to fixing current of sorts, a hypoxia of a fetus, development of an ascending infection, a bleeding in postnatal and early postnatal the periods and to rising of frequency of postnatal diseases.

The diagnosis put on the basis of dynamic observation over character of patrimonial activity - weak, short fights, long pauses between them, the slowed down disclosing of passage of a uterus (define at. A vaginal examonation), slow forward promotion of a presenting part of a fetus. From additional methods of research use a cardiography, an external hysterography.

Excessive patrimonial activity is caused by a hypertonus of a uterus and clinically expressed by very frequent fights with the truncated intervals between them. Labors come to an end quickly (promptly), thus there is a frustration of a uteroplacental circulation and a hypoxia of a fetus. The child often is born with the phenomena of an intracranial birth trauma.
