[The nature of the major pathology in the perinatal period at the present time].

The main pathology leading to mortinatality has been determined. It is shown that in 57.8% of cases mortinatality is associated with placental insufficiency, the reason for which can be found out by the pathoanatomical study of the afterbirth. It is proposed to differentiate afterbirth disorders of implantation, placentation, circulation and inflammatory changes. Fifty per cent of neonates are shown to die from the respiratory failure associated with the formation of atelectasis, hyaline membranes and edema with pulmonary hemorrhages. Next in frequency are cephalic ventricle extravasations. The main pathogenetic factor of both neonatal pathologies is prematurity with functional and morphological tissue immaturity.

[Complications of resuscitation and intensive therapy in infants (proceedings)].

Most frequent complications of infusion therapy in children include thrombosis and thrombophlebitis of the umbilical and subclavian veins. In the perinatal period thrombophlebitis of the umbilical vein is due to exogenous infection and becomes the source of umbilical sepsis. Thrombophlebitis of the subclavian vein in nurslings results more frequently from endogenous infection. Because of morpho-functional immaturity in infancy, hyperhydration of tissues is extreme, with vacuolar dystrophy of cells up to their necrosis, particularly in the liver and kidneys. Artificial pulmonary ventilation (APV), particularly in premature newborns, is frequently accompanied by breaks of alveolar septae, development of bullous and interstitial emphysema, pneumothorax. In deeply premature infants APV may be ineffective because of immaturity of the lung tissue.

[Septicemia in children according to autopsy data].

Analysis of section material was carried out covering the period 1943-1975. It was established that proportion of septic diseases in the general structure of children's mortality in the recent years was stabilized at rather high levels (1973-1975--17.1%). Fatal outcomes were most often among infants at the early period of life in whom sepsis developed against the background of premorbid factors including prematurity, malformations, pathologic labour, mother's diseases, etc. The course of sepsis was particularly severe in infants with congenital immunodeficient states. The main pathogene of sepsis at present is staphylococcus. During the period under study, correlation and morphology of various forms of sepsis varied depending upon the pathogene and therapy applied. Since 1968 and up to new the most common form of sepsis has been that morphologically identical to sepsis observed in 1943-1947, i.e. before the wide application of antibiotics.
