The new NB scope aids in better visualization of the scalp and blood collection and analysis at bed side.
Caesarean section rates and inherent complications are on the rise all over the world. One way to avoid a caesarean is to measure fetal scalp blood lactate levels. The methods available to visualize fetal scalp, obtain the blood sample and perform the blood test are separate, cumbersome and expensive, needing a certain level of expertise. We propose a device that incorporates all the steps of obtaining a fetal scalp blood lactate into one sleek, easy to use device.
The initial design, 3-D print and was tried on mannequin. After ethics committee approval, the prototype was experimented on patients in labour with singleton live fetus in cephalic presentation with no evidence of distress.
There were ( = 9) patients recruited. There were ( = 5) primigravida and ( = 4) multigravida all of whom were in active labour. Parity did not seem to influence ease of instrumentation. Of the ( = 9) mothers ( = 2) had meconium-stained liquor and the rest ( = 7) had clear liquor, meconium-stained liquor did not affect visualization. The mean time taken to collect the sample was 184.11(± 33.04) seconds.
The Neeraj-Bhaskar (NB) scope is an easy to use, affordable device that can be used time and again to decide on cases where emergency caesarean section can be avoided due to fetal distress.
新型NB探头有助于更好地观察头皮情况,并在床边进行血液采集和分析。
全球剖宫产率及其固有并发症呈上升趋势。避免剖宫产的一种方法是测量胎儿头皮血乳酸水平。现有的观察胎儿头皮、采集血样和进行血液检测的方法相互独立、繁琐且昂贵,需要一定的专业技能。我们提出一种设备,将获取胎儿头皮血乳酸的所有步骤整合到一个外形简洁、易于使用的设备中。
进行初步设计、3D打印,并在人体模型上进行测试。经伦理委员会批准后,该原型在单胎头位、无窘迫迹象的临产患者身上进行试验。
共招募了9名患者。其中初产妇5名,经产妇4名,均处于活跃期分娩。产次似乎不影响器械操作的难易程度。9名母亲中,2名羊水有胎粪污染,其余7名羊水清澈,羊水胎粪污染不影响观察。采集样本的平均时间为184.11(±33.04)秒。
Neeraj-Bhaskar(NB)探头是一种易于使用且价格实惠的设备,可反复用于判断因胎儿窘迫而可避免紧急剖宫产的情况。
