The viability of premature babies is minimal at 22 weeks' gestation
Date:9/18/2014

A new study analyses the survival rates in Spain of newborns with a gestational age under 26 weeks. The results show that survival under 23 weeks is 'exceptional', although other factors such as birth weight and sex also have an influence.

Experts from the Spanish Society of Neonatology have studied the survival rates in Spain of newborns with a gestational age under 26 weeks, taking into account that a newborn carried to term is between 37 and 42 weeks.

The data have been drawn from the national database that gathers information on all babies born weighing less than 1.5 kilos. This database is constantly being updated and is used to ascertain the results of the care provided to these premature babies with less than 32 weeks' gestation.

"The more premature they are, the more complications they present due to their prematurity and the lower their chances of survival," Fermn Garca-Muoz Rodrigo, of the University Maternity Hospital of Las Palmas de Gran Canaria and one of the authors of the study, explained to SINC.

"And, when they do survive, they are at high risk of suffering from sequelae in their neurological and sensory development".

For this study, published in the Anales de Pediatra journal, the experts only analysed the youngest newborns, in other words, 3,236 babies born after 26 weeks or less of pregnancy. According to the experts, the so-called 'limit of viability' is between 22 and 25 weeks.

"Babies rarely survive at 22 weeks and, when they do, it is at the expense of enduring many complications and long hospital stays, which involve a lot of suffering for them and their families," Garca-Muoz Rodrigo added.

The chances of survival increase from that point onwards and the proportion of complications gradually decreases as the gestational age rises. Indeed, babies at 26 weeks, despite being very high-risk, are considered viable and are a benchmark group for comparing the results from the other gestational ages.

The results show that the precise survival rates by gestational age were 12.5%; 13.1%; 36.9%; 55.7% and 71.9% at 22, 23, 24, 25 and 26 weeks, respectively.

Survival with no serious intracranial haemorrhage, periventricular leukomalacia (damage to the brain's white matter close to the ventricles), bronchopulmonary dysplasia (chronic lung disease) or retinopathy of prematurity (abnormal development of the blood vessels in the retina) stood at 1.5%; 9.5%; 19.0% and 29.9% at 23, 24, 25 and 26 weeks, respectively.

"Survival with no serious illness in newborns under 23 weeks is exceptional, and very low in newborns of 23 and 24 weeks," the doctor pointed out. "Newborns of 25 weeks or more have a reasonable chance of survival and, in the absence of major malformations, they should be given active resuscitation and intensive care".

Other Relevant Factors

The group of authors will shortly publish another study which analyses other factors that may have an influence on the survival of these babies, in addition to gestational age.

"Birth weight the higher, the better, sex girls develop a little better than boys, whether or not the mother was given corticoids before giving birth to help to develop the baby's lungs and single foetuses compared to multiple pregnancies are very important factors as they all increase the chances of survival," Garca-Muoz Rodrigo underlined.

The expert concluded by saying that medicine is not an exact science and that every birth must be treated on an individual case-by-case basis. "Other factors such as whether or not the foetus presents malformations, the monitoring of the pregnancy, the parents' values and expectations, etc., are details that should also be taken into consideration".
