Related to neonatal mortality: postneonatal mortality
the statistical rate of infant death during the first 28 days after live birth, expressed as the number of such deaths per 1000 live births in a specific geographic area or institution in a given time.
mortality(mor-tal'it-e) [ mortal]
1. The condition of being mortal.
2. The number of deaths in a population. In the U.S. about 2,300,000 people die each year. The most common causes of death, according to the National Center for Health Statistics, are (in descending order) heart disease, cancer, stroke, chronic obstructive lung disease, accidents, pneumonia and influenza, diabetes mellitus, suicide, kidney failure, cirrhosis, and other chronic liver diseases. The causes of death vary by age group: accidents are the most common cause of death among infants, children, adolescents, and young adults; cancers are the most common cause of death among people ages 45 to 64. Heart disease predominates after age 65. See: table
All of the deaths that occur in a population, regardless of the cause. It is measured in clinical trials and used as an indicator of the safety or hazard of an intervention.See: disease-specific mortality
All of the deaths that occur in a population from a specific illness. In clinical trials that study the effect of a treatment on that illness, it is used as a measure of the treatment's effectiveness.See: all-cause mortality
The number of deaths of children younger than 1 year of age per 1000 live births per year.
The death of a newborn.
The number of fetal deaths plus the number of deaths of infants younger than 7 days of age per 1000 live births per year.

pertaining to the period immediately after birth; the duration varies between species; in humans refers to the first four weeks of life; in animals the first week seems appropriate. Some neonatal disorders are listed in entries below. Others are listed elsewhere under titles specific to their anatomic location, including hyaline membrane disease, respiratory distress syndrome.
neonatal cardiac murmur
is observed in foals and most disappear before the fifth day. Persistence after that time may suggest valvular dysfunction. Many congenital murmurs are functional and cause no signs of disease.
see undifferentiated diarrhea of the newborn.
see neonatal maladjustment syndrome (below).
usually caused by obstruction to lymphatic flow by defective development of lymph drainage system.
neonatal hyaline membrane disease
see hyaline membrane disease.
see neonatal jaundice (below).
a metabolic disease of newborn piglets caused by restriction of food intake. Clinical signs include weakness, shivering, hypothermia and terminal convulsions.
see alloimmune hemolytic anemia of the newborn.
neonatal isoimmune purpura
see neonatal thrombocytopenic purpura (below).
is an important clinical sign in foals because of the possibility of alloimmune hemolytic anemia. Some cases of benign, physiological jaundice also occur in foals. There is jaundice but no other clinical or pathological abnormality. Called also neonatal hyperbilirubinemia.
neonatal maladjustment syndrome
a disease of newborn thoroughbred foals caused by premature severance of the umbilical cord in assisted foalings and by hypoxia due to other causes. The foals may be normal for some hours after birth. Clinical signs include aimless wandering, apparent blindness, and convulsions including a sound like a dog barking. Called also barkers and wanderers.
death in the neonatal group.
occurs rarely. Lymphosarcoma, benign and malignant melanoma and myeloid leukosis are recorded. Sporadic bovine leukosis, manifested by many subcutaneous tumors, is the most common form of the disease.
see ophthalmia neonatorum.
many bacteria, which are not widely invasive in older animals, can cause septicemia in neonates because of their immunological immaturity; common examples are Escherichia coli, Listeria monocytogenes, Salmonella spp., streptococci, e.g. S. suis.
an inherited disease of calves which are normal at birth but soon develop a susceptibility to tetanic convulsions when stimulated. See also neuraxial edema.
neonatal streptococcal infection
occurs in all species, but is especially important in piglets and foals. Bacteremia and septicemia may result in the animal's death or the development of arthritis, endocarditis, meningitis or ophthalmitis. Causative bacteria are: foals—Streptococcus zooepidemicus (S. pyogenes equi); piglets—S. suis types 1 and 2, S. equisimilis; calves—S. pyogenes; lambs—S. faecalis and group C streptococci.
neonatal thrombocytopenic purpura
a severe bleeding disease in piglets a few days old which have drunk colostrum containing antiplatelet antibody from their alloimmune dam.
amount of physical activity displayed by the newborn animal; an indication of the potential viability of the patient.
