              四維彩超檢查前需要注意什么
              1651809546

              四維彩超檢查沒有特殊注意事項,建議做之前不要吃太飽,也不要喝太多水,避免胃過度充盈對子宮產生擠壓而影響胎兒活動空間,不利于觀察。四維彩超檢查前半小時左右最好適量吃東西或者喝水可以促使胎兒胎動,更有利于仔細檢查。檢查時間最好避開寶寶睡眠時間,選擇寶寶胎動比較頻繁時間段做比較好。四維彩超檢查主要用于檢查胎兒是否有發育畸形等情況,屬于大排畸檢查。雖然在懷孕12周以后就可以做,但是在懷孕20-26周之間做最合適。因為這個時期胎兒各器官基本已經發育成熟且胎兒不是太大,在宮腔活動空間最大,胎動也比較頻繁以有利于觀察的更清楚
