The word perinatal means relating to a period slightly before and after birth. This is usually considered to be a couple of weeks.
Peri is a suffix that means about. So perinatal would mean about the time of birth.
That is the correct spelling of the adjective "perinatal" (around the time of birth).
Perinatal transmission is more likely if the waters break prematurely.
The perinatal mortality rate is calculated using the formula: [ \text{Perinatal Mortality Rate} = \left( \frac{\text{Number of perinatal deaths}}{\text{Total number of births (including stillbirths)}} \right) \times 1,000 ] Perinatal deaths include stillbirths and deaths within the first week of life. This rate is typically expressed per 1,000 total births.
Perinatal asphyxia can occur a long time before birth, shortly before birth, during delivery, or after birth
Chapter 16 is the chapter in the ICD-10 that contains codes for the perinatal period.
