Preeclampsia, a pregnancy-specific disorder, is the third leading cause of maternal morbidity and mortality worldwide. METHOD OF APPROACH: To develop a device to detect preeclampsia in pregnant women living in low resource environments, a method was needed that had to be very low cost and, preferably, easily monitored by the woman herself. Due to the high cost and expertise involved in monitoring the two diagnostic criteria of preeclampsia (elevated blood pressure and proteinuria), edema, an indicator of preeclampsia was chosen instead. RESULTS: The general principle of the method is to have each pregnant woman, early in pregnancy, fitted, on either her wrist or ankle, with a detection band, which is set to a preset expansion limit (e.g., expansion by 5%). When edema causes that body part to swell to the limit, the pregnant mother knows that she should seek medical assistance. CONCLUSIONS: The resulting prototype device and calibration method requires little knowledge, and is very durable, cost-effective and portable.
子痫前期是一种与妊娠相关的疾病,是全球孕产妇发病和死亡的第三大主要原因。
为了开发一种用于在资源匮乏环境中生活的孕妇中检测子痫前期的设备,需要一种成本非常低且最好能由孕妇本人轻松监测的方法。由于监测子痫前期的两个诊断标准(血压升高和蛋白尿)涉及高昂成本和专业知识,因此选择了作为子痫前期指标的水肿。
该方法的总体原则是让每位孕妇在怀孕早期在其手腕或脚踝上佩戴一个检测带,该检测带设置为预设的扩张极限(例如,扩张5%)。当水肿导致该身体部位肿胀到极限时,孕妇就知道她应该寻求医疗帮助。
由此产生的原型设备和校准方法所需知识很少,且非常耐用、经济高效且便于携带。
