Severodonecke

Severodonecke in forensic against. When forensic medical study of the corpse of a newborn is set, the child was born dead or alive. The definition of live birth is made by ascertaining whether the newborn independent breathing.
Methods of definition of live birth are the so-called living samples. Key life samples serve as a hydrostatic test - establishing a presence in the lungs or the gastrointestinal tract air or other gas.
Light breathing of the newborn, the pieces cut from them, tied at the entrance and exit of the stomach and intestines contain air and when immersed in water swim. Life tests are not always reliable, because the air can get into the lungs during artificial respiration, and gases formed by the decay.
Much greater confidence in severodonecke is set in radiological and histological studies. Detected by x-ray presence of air in the lungs and gastrointestinal tract is usually evidenced by the live birth.
The newborn breathing histological examination of the drug light visible alveoli round shape and about equal size, gleams of the bronchi and bronchioles round or oval. The alveoli nedyalsko newborn - slit-like or irregular shape; small and medium-sized bronchi are spasams condition. If applied artificial respiration, the alveoli uneven and in the tissue between them can be air. Formed when the rotting corpses stillborn gases contained in millionares connective tissue and the alveoli, but most of the parenchyma of the lung remains unmounted. Detection of hyaline membranes (deposition on the inner surface of the alveoli or bronchioles glinoporoshka substances crusaders eosin) evidence of live birth.
Severodonecke confirmed by detection of debriscaught in the respiratory tract after birth.
Diagnosis of live birth place on the basis of the results obtained in the study of all these methods.
