女性怀孕期间有必要做胎位检查嘛?具体什么时间检查好?

胎位检查有必要做吗

胎位是指胎儿在母体内的姿势,胎儿在母体子宫里的正确姿势应该是头朝下,屁股朝上。胎儿出生前在母体子宫里的姿势很要紧,它关系到孕妇是顺产还是难产,顺产的胎儿头部应该先进入阴道,有很多的胎儿头部先进入到阴道,但是头部是仰着的,也属于胎位不正,胎位不正对于胎儿和母体的危害很大。
 
而胎位检查有必要做吗?答案是肯定的。胎位检查的作用:通过孕晚期的一系列检查,基本能确定胎位的正常与否。如果发现准妈妈胎位不正,就可进行胎位的矫正;胎位也是分娩方式选择的依据之一。
 
由于胎位不正会给分娩带来不同程度的困难和危险,故早期纠正胎位,对难产的预防有着重要的意义。
 
怀孕7个月前,由于羊水相对较多,胎儿较小,在子宫内活动范围较大,所以位置不容易固定。在孕7个月前发现的胎位不正,此时在医生的指导下能调整过来的可能性较大。反之,如果过晚检查,在孕34周后才发现胎位不正,此时胎位可调整过来的可能性不大,因此准妈妈需要做好选择剖腹产的心理准备。
 

胎位检查是什么

胎位检查是产前检查的主要项目之一,一般在妊娠七个月左右检查。由于胎位异常将给分娩带来程度不同的困难和危险,故早期纠正胎位,对难产的预防有着重要的意义。那么,胎位检查是什么呢?
 
胎位检查,就是检查胎儿在母体子宫内的位置,一般在怀孕7个月以后可通过B超和触诊等方式检查。胎位不正一般是指妊振30周后,胎儿在子宫体内的位置不正,较常见于腹壁松弛的准妈妈和经产妇。胎位不正包括臀位、横位、枕后位、颜面位等。其中,臀位比较常见,横位对准妈妈和胎儿的影响是最严重的。
 
胎儿出生前在子宫里的姿势非常重要,医学上也把胎位做为分娩方式的选择依据之一。比较合适的胎位调整时间为为孕30—32周。
 
胎位是指胎儿先露的指定部位与母体骨盆前、后、左、右的关系,正常胎位多为枕前位。妊娠30周后经产前检查,发现臀位、横位、枕后位、颜面位等谓之胎位不正,其中以臀位为常见。胎位不正如果不纠正,分娩时可造成难产。

 

胎位loa是什么意思

胎位的学问其实是比较大的,胎位本身的种类其实也有比较多的。所以,不少的孕妇对于胎位的了解也是比较重要的,因为不少孕妇对此知识比较少,胎位loa的知识有不少的很多孕妇根本就不了解。下面就一起去看看究竟胎位loa是代表的什么意思吧。
 
胎位loa指的就是一些身体上的胎位缩写方式,胎位首先是属于一些先露部,代表的是在产妇的骨盆所在的一些位置,当然也是指的骨盆的四相位,就是右前、左后、左前、右后这些地方。
 
预产期不是精确的分娩日期,科学家们统计过只有53%左右的妇女在预产期那一天分娩。预产期可以提醒胎儿安全出生的时间范围,但不要把预产期这一天看得那么精确。真正分娩在预产期的39周左右都属正常。如果胎儿正常最好顺产,不论是剖腹还是自然分娩最好都是要等到疼了后在决定,最好是顺产,对宝宝和妈妈都好。
 
子宫出现不规则收缩,孕妇会感到肚子隔一定时间就紧一次,越来越勤,这是开始临产的一个重要现象。子宫开始有规则收缩前后,会流出一些混有血的粘液,这就是见红,医学上叫做产兆。见红是由于子宫颈宫逐渐扩张大,子宫颈里的粘液和子宫颈宫壁少量出血混会在一起形成的;血量不多,是开始临产的可靠现象;如果血量多,超过了月经量时,就要注意是否有产前出血,要及时做进一步检查。绝大多数产妇是在子宫口开全前后破水,少数产妇可在开始临产前破水,所以,怀孕到月,若是流出羊水时,表示已经破膜,要开始临产了。
 
胎位loa属于女性在孕前的一种检查兆头,要是我们怀孕一个月的时间的话,妇女要随时的时间去注意临产的先兆,并且需要我们不需要到时去检查医院等待分娩,切勿等到了便胀感的时间就要去医院或者是去找接生员正规接生才是。
 

胎位roa是什么意思

胎位的检查基本上从孕28周后即开始做检查,频率为每2周一次;在32周之后,胎位基本上已经确定了。有些孕妈妈在做B超检查的时候,每次医生都写胎位roa,那胎位roa是什么意思?
 
胎位是指胎儿先露的指定部位与母体骨盆前、后、左、右的关系,正常胎位多为枕前位。妊娠30周后经产前检查,发现臀位、横位、枕后位、颜面位等谓之胎位不正,其中以臀位为常见。胎位不正如果不纠正,分娩时可造成难产。
 
而胎位roa是胎儿在子宫内的位置是右枕前的意思,属于正常胎位,孕妈妈无须紧张。B超roa为顶先露,枕骨在骨盆右侧,朝前,胎位为右枕前位,在顺产的最佳胎位来讲,这种胎位排第二。
 
胎位的写法由三方面来表明:
 
1、代表骨在骨盆的左侧或右侧,简写为左(L)或右(R);
 
2、代表骨名称,如顶先露为“枕”,即“O”,臀先露为“骶”,即“S”,面先露为“颏”,即“M”,肩先露为“肩”,即“Sc”;
 
3、代表骨在骨盆之前、后或横,例如顶先露,枕骨在骨盆左侧,朝前,则胎位为左枕前(LOA),为最常见之胎位。
 
顶先露有六种胎位:
 
左枕前(loa);左枕横(lot);左枕后(lop);右枕前(roa);右枕横(rot);右枕后(rop)这些都属于正常胎位。
 
产前定期检查很重要,如果孕妈妈发现宝宝胎位不正,应及时加以纠正,减少难产的风险。
 

胎位检查要注意什么

通常,医学上称枕前位为正常胎位,这种胎位分娩一般比较顺利。而在产前做的胎位检查主要是检测胎位是否不正,如果胎位不正的话,可能就需要做出相应措施,那么胎位不正需要注意什么?
 
1、横位应做选择性剖腹产,臀位分娩,初产妇多作剖腹产;经产妇,胎儿较小、骨盆够大者,可考虑阴道分娩。
 
2、膝胸卧位操纠正,孕妇排空膀胱,松解腰带,在硬板床上,俯撑,膝着床,臀部高举,大腿和床垂直,胸部要尽量接近床面。每天早晚各1次,每次做l5分钟,连续做1周,然后去医院复查。
 
3、医生为孕妇施行转向,如果在孕32周-34周时,胎儿仍未转向,医生就要考虑为孕妇实行外转胎位术,让胎儿翻转,使孕妇能顺利分娩,外转胎位术有一定的风险性。操作时,会导致脐带缠绕或胎盘早剥。
 
4、针对胎位不正,我国有针灸治疗的成功先例。用针刺至阴穴,治疗胎位不正,每日1次,每次l5~20分钟,5次为一疗程,适用于妇科检查诊断为臀位、横位、斜位的孕妇。
 
5、作好产前检查,预先诊断出胎位不正,及时治疗,如未转为头位,则需要在预产期前1~2周住院待产,由医生根据孕妈妈的具体情况决定分娩方式。
