要点提示:十月怀胎共40个周期,怀孕40周时,应该是‘瓜熟地落’了,但也有一部分宝宝到现在还不愿意“出来”。不用太过紧张,预产期提前或推迟一到两周都是正常现象,所以不用惊慌。

宝宝发育与母体变化

胎儿的情况:

进入怀孕40周时,胎儿的各个器官已完完全全的发育成熟,要准备降生了。怀孕40周出生的宝宝平均体重在3.3~4千克左右,身长大概有51厘米。大多数的胎儿会在预产期这一个孕周期降临,据统计,真正能准确地在预产期出生的婴儿只有5%。超过两周还不分娩,就及时就诊。

母体情况:

进入怀孕40周的孕妈妈,十月怀胎你已经是“满月”了哦。马上就要分娩的孕妈咪,这个时候的宫高增加到30~34厘米,胎儿位置向下降,孕妈妈随时可能分娩,因此要做好去医院的一切准备了。首先你要准备好生育卡、保健册、医保卡等入院手续必备品,等待分娩征兆的到来。

怀孕四十周重点关注

确认预产期

由于现在很多女性的月经周期不规律,或者周期较长,甚至有记不清楚者,所以对于临近40周仍无产兆的孕妈咪,建议最好请医师确认预产期是否正确。“月经算法”有时需要修正,或者用超声波的CRL值来进一步确认预产期。

第1步 加强产前检查

缩短检查间隔时间,随时与医生取得联系,告知宫内胎动情况,同时B超随访羊水量。如果无异常,可在密切监护下继续妊娠。  >>>纠正胎位的正方法(图)       >>>【预产期】预产期怎么计算 预产期计算方法  

第2步 运动+催产

虽然过期妊娠的原因还不明确,但绝大部分产科医生认为这跟孕妇本身的体质及怀孕后期是否做适度的运动有关。这个时候你可以每天散步30分钟以上或每天缓慢上台阶数次。(适用不会喘得太厉害、不会造成异常宫缩的妈咪)     

孕41周时可到医院催产

催产可以说是孕妇期盼自然产的最后关键,过去产科认为要过了42周医生才需要为孕妇做催产,但现今医学发现,42周后孕妇的胎盘可能已经老化(48%的人已经是第三级),其功能变差,羊水也变少了,事实上,这个时候催产的效果并不佳,所以现在只要过了40周仍未生产即可进行催产。    >>>孕晚期 必须立刻入院待产的4种情况

本周饮食要点

怀孕40周孕妇吃什么好,顺产相当于一次重体力劳动,产妇必须有足够的能量供给,才能有良好的子宫收缩力,宫颈口开全才有体力把孩子生出。如不好好进食、饮水就会造成脱水引起全身循环血容量不足,当然供给胎盘的血量会减少,引起胎儿宫内缺氧。引起宫缩乏力、难产、产后出血等危险情况。   >>>让顺产分娩更顺利的饮食与运动

分娩前如何进食?

虽说在预产期分娩的孕妇只占5%,但临近分娩的孕妇饮食,主要还是以帮助孕妇顺利分娩为主。此时的孕妇饮食应以富含糖分、蛋白质、维生素并且易消化为好。可根据自己的爱好,选择蛋糕、面汤、稀饭、肉粥、藕粉、点心、牛奶、果汁、西瓜等多样食品。每天进食4-5次,少食多餐。 初产妇从有规律性宫缩开始到宫口开全,大约需要12小时。    >>>怀孕晚期要多吸收哪些营养      >>>孕妇可以吃巧克力吗?     >>>孕期饮食的十大禁忌 

如果孕妈妈是初产妇,无高危妊娠因素,准备自然分娩,可准备一些易消化吸收、少渣、可口味鲜的食物,如鸡蛋汤面、排骨汤面、牛奶、酸奶、巧克力等食物,同时注意补充水分,让自己吃饱吃好,为分娩准备足够的能量。

另外,在进产房之前,你可以为自己准备一些助生产的小零食,既能缓解产房中紧张的情绪还能快速的补充能量,为分娩减少痛提高顺产成功率做好准备。    >>>利于胎儿大脑发育的七种食品

孕检事项

怀孕40周要做什么检查?已进入分娩周期的孕妈妈,这次检查要复查血、尿常规,产科检查(宫高、腹围、胎心、胎位检查、血压、体重),指导自数胎动及临产征兆,胎心监测。

胎教提示

大多数妈妈都认为,随着分娩过程的完成,胎教也就随之告一段落。然而,由于新生宝宝出世后的前6个月是大脑细胞增殖的另一高峰,因此,为了继续促进宝宝的智力发育,此时的准爸准妈,还是要坚持做好胎教工作哦。

你可以把每天把生活中愉快的事情讲给宝宝听,让他意识到等待他的世界是美好的,通过和胎儿共同生活、共同感受,培养他热爱生活、果断自信、活泼外向等优良性格,使母子、父子间的纽带更牢固。
