METHOD FOR EVALUATING VIABILITY IN NEONATALS WITH EXTREMELY LOW BODY WEIGHT ACCORDING TO THYMIC STATE Russian patent published in 2005 - IPC

FIELD: medicine, pathological anatomy.

SUBSTANCE: the present innovation deals with detecting viability in neonatals of 22-27-wk-long gestation, at their body weight up to 1 kg based upon evaluation of thymic morphological maturity. Moreover, in 10 visual fields in medullary substance in thymic lobules one should calculate the content of Hassal's bodies and reticuloepithelial cells. If the content of reticuloepithelial cells is above 10 and Hassal's bodies - above 2 one should consider a neonatal to be a viable one, at the content of reticuloepithelial cells being below 9 and Hassal's bodies - below 2 - as nonviable one. This method enables to detect quantitative criteria in evaluating the viability in neonatals at extremely low body weight by thymic state for the first time, helps to increase accuracy and simplify pathologoanatomical diagnostics of viability and objectively evaluate tactics and purposefulness of resuscitation procedures.

EFFECT: higher accuracy and efficiency of evaluation.
