In Ontario, approximately 140,000 women deliver newborn infants each year. Of these women, 60,000 to 70,000 have multiple marker screening, 10,000 undergo amniocentesis or chorion villus sampling and virtually all have at least one prenatal ultrasound. Multiple marker screening is not used in every province and territory; however, amniocentesis and prenatal ultrasound are used throughout Canada. Most paediatric patients will have been exposed to some form of prenatal diagnosis. If an abnormality is found prenatally, parents may have concerns to discuss with the paediatrician after the child is born. Likewise, if a child with a problem is born following a normal pregnancy, the parents will want to know why the problem was missed prenatally. Paediatricians should be aware of prenatal tests that have been performed to understand better their patients and their families.
在安大略省,每年约有14万名妇女分娩新生儿。在这些妇女中,6万至7万人进行多项标志物筛查,1万人接受羊膜穿刺术或绒毛取样,几乎所有人都至少进行过一次产前超声检查。并非每个省和地区都使用多项标志物筛查;然而,羊膜穿刺术和产前超声检查在加拿大各地都有应用。大多数儿科患者都曾接受过某种形式的产前诊断。如果产前发现异常,孩子出生后父母可能会有一些问题要与儿科医生讨论。同样,如果在正常妊娠后出生的孩子有问题,父母会想知道为什么产前没有发现这个问题。儿科医生应该了解已进行的产前检查,以便更好地了解他们的患者及其家庭。
