IUGR or Intra-uterine growth restriction is a condition when the fetus is smaller as compared to the expected number of weeks of gestation, because of related health problems such as inadequately developed heart that could cause major bearing on the baby’s health as extreme as brain damage.

When IUGR is detected, doctors employ ultrasound for tracking the baby’s health and determining the appropriate delivery time. However, such measurements are mostly imperfect and gynaecologists had to resort to erudite conjectures regarding the strength of an unborn baby’s circulatory system.

IUGR babies would now have enhanced likelihood of a healthier living with due gratitude to a novel research from Tel Aviv University.

Professor Ofer Barnea from TAU’s Department of Biomedical Engineering in partnership with Professor Jacob from the Wolfson Medical Center, links mathematical models with data regarding a baby’s physiology within the womb. Coalescing ultrasound with potent algorithms based on data derived from real-life, paediatricians acquire vital data on the growth of the fetal circulatory system, so they could establish when the baby is healthy enough to continue to exist.

Professor Barnea states that babies having IUGR undergo stress and growth limitations within the womb. Doctors require weighing up their growth, but presently they have to depend on incomplete information from ultrasound systems. In case the baby is left within the womb for too long, then there are chances of brain damage occurring.  Conversely, the doctors require to ensure that the baby’s heart is fit enough to stay alive outside the womb.

Summarising it all up

Professor Barnea’s group of biomedical engineers and physicians proffer a means to visualise the entire picture so that improved medical decisions could be taken.

Professor Barnea stated that they could now illustrate to the doctors what the human eye fails to spot. Their system incorporates discernible data with mathematical models taken of the fetus’s or newly born child’s circulation.

Prof. Barnea is presently evolving the know-how in a novel direction along with Professor William P. Santamore from Temple University and Nemours Children’s Hospital for managing and optimising operative restorations in newly born children having heart anomalies. It could one day be obtainable for also treating adults.

Professor Santamore stated that this is a significant advancement in paediatric medicine wherein data obtained from babies are delivered to the computer for estimating pressure, flow and other factors that could not be otherwise determined in their small-sized hearts.

The system was initially set up for treating hypoplastic left heart syndrome – a condition wherein the left part of the heart fails to function. In case this is not detected soon, the outcomes could be disastrous. Presently, doctors offer medications with prostaglandins and then carry out operation. However, as measuring the flow of blood to the lung of an unborn are not doable, it is tricky for the doctors to understand means of optimizing flow distribution and managing the baby.

Equating a safer child birth

Professor Barnea’s mathematical model of baby’s heart system offers this data to the doctors to treat heart ailments since birth, and has by now altered the manner in which the health of these children are administered. He stated that they are merging these fundamental physiological outcomes with a more refined mathematical model of circulation in newly born babies, adjusting it the individual employing online calculated data.

The scientists are aiming at developing their novel IUGR tool as a bedside monitoring device that would be based on real information. Feasibility studies are presently on going, and the tool could unravel its course into hospitals in as soon as 2 years.
