Influence of cause of death on body and internal organs weight in perinatal autopsies - Revista Brasileira de Ginecologia e Obstetrícia
To evaluate changes in body and internal organ weight of autopsied children in the perinatal period and their relationship with the cause of death.
One hundred and fifty three cases of perinatal autopsies performed at a university hospital in Southeastern Brazil ere included. Information about cause of perinatal death, date of autopsy, gestational age, perinatal weight and organ weight was obtained from the autopsy protocols and medical records of the mother and/or the newborn. Four groups of causes of death were defined: congenital malformations, perinatal hypoxia/anoxia, ascending infection and hyaline membrane. Brain, liver, lungs, heart, spleen, thymus and adrenals were analyzed.
The weight of children with perinatal hypoxia/anoxi (1,834.6±1,090.1 g versus 1,488 g), hyaline membranes (1,607.2±820.1 g versus 1,125 g) and ascending infection (1,567.4±1,018.9 g versus 1,230 g) was higher than expected for the population. Lung weight was higher in cases with ascending infection (36.6±22.6 g versus 11 g) and lower in cases with congenital malformations (22.0±9.5 g versus 40 g). Spleen weight was higher in children with ascending infection (8.6±8.9 g versus 3.75 g ) and adrenal weight was lower in cases with congenital malformations (3.9±2.1 g versus 5.5 g). Thymus weight was lower in cases with miscellaneous causes (3.7±1.2 g versus 7.5 g) and spleen weight was lower in patients with lung immaturity (0.4±0.1 g versus 1.7 g). All results showed significant differences.
This study demonstrates that variations in the weight of children and the weight of their organs are related to the types of cause of perinatal death. These data may contribute to a better interpretation of autopsy findings and their anatomical and clinical relationship.
