早孕期妊娠毒血症篩查
First-trimester Preeclampsia Screening

妊娠毒血症是什麼?
妊娠毒血症是一種嚴重的妊娠併發症,影響全球約2至8%的孕婦,傳統的診斷是基於妊娠20週後出現的高血壓和蛋白尿。醫學界普遍認為妊娠毒血症主要是胎盤功能較差所致,令胎盤無法提供足夠的血液給胎兒,導致子宮動脈血管舒張不良,繼而引致妊娠毒血症的常見症狀,例如頭痛、視力模糊、噁心、嘔吐和腿部腫脹。

What is Preeclampsia?
Preeclampsia is a serious pregnancy complication affecting 2-8% of pregnant women worldwide. Preeclampsia is traditionally diagnosed based on high blood pressure and presence of protein in urine after the 20th week of gestation. Symptoms include headache, blurred vision, nausea, vomiting and leg swelling.

This disorder is thought to be caused by poor function of the placenta, which leads to its inability to support the adequate blood supply required by the fetus, and poor uterine arterial vasodilatation, attributing to the common symptoms of preeclampsia.

為什麼要接受篩查?
妊娠毒血症是孕婦和胎兒產生併發症和死亡的主要原因。研究證實通過篩查和早期風險評估,可以採取預防措施來降低妊娠毒血症風險。

本篩查嚴格符合國際婦產科聯合(FIGO)在2019年推薦的最新指引,並且證實達至早孕期妊娠毒血症篩查的國際標準。

Why Screening?
Preeclampsia is a major cause of morbidity and mortality for both the mother and fetus. Currently, research suggested that through screening and early risk assessment, preventive measures could be instigated to reduce the risk of preeclampsia development.

Our screening follows the newest guidelines set by the International Federation of Gynecology and Obstetrics (FIGO) in 2019 and is evidenced to be in line with the global standards for first-trimester preeclampsia screening.

誰適合參與此篩查?
所有懷孕第11+0 至13+6 週的單胎孕婦

Who is Eligible?
All women with a singleton pregnancy between their 11+0-13+6 weeks of gestation.

篩查步驟
篩查分為四個部分:

  1. 記錄孕史及病史
  2. 抽取血液樣本
  3. 雙手測量血壓兩次
  4. 進行超聲波掃描評估子宮動脈流量

Screening Process

  1. Record obstetric and medical history
  2. Take blood sample
  3. Measure blood pressure twice in both arms
  4. Ultrasound scan to measure uterine artery blood flow

完成篩查後
大約3個工作天便可得知早產妊娠毒血症的風險評估結果。

若篩查結果顯示為高風險,我們會為你安排覆診作進一步跟進。

After Screening
The result of estimated risk of preterm preeclampsia will be available in approximately 3 working days.

If you are screened high risk for preeclampsia, you will be invited to attend a follow up visit for further counselling.
