Children who have undergone heart surgery as infants may risk hearing loss by the age of four, in addition to poor language skills and cognitive problems, researchers have found.

Researchers discovered that around 21 percent of 348 pre-schoolers, who had survived cardiac surgery, suffered hearing loss. This rate was 20 times higher than that prevalent among the general population.

For the study, published in the Journal of Pediatrics, the researchers analyzed neurodevelopmental outcomes in these children. A total of 75 children were found to have developed hearing loss.

The study suggested that children who undergo heart surgery should have their hearing evaluated by age 24 to 30 months, to increase their chances of receiving a timely medical intervention.

“Children born with life-threatening heart defects require a great deal of sophisticated care before and after surgery,” said the lead author of the study Nancy B. Burnham, a nurse-practitioner in the Division of Cardiothoracic Surgery at the Children’s Hospital of Philadelphia. (IANS)

If you are planning to start motherhood, quit smoking, say researchers. Exposing your baby to tobacco smoke during pregnancy or after the birth may cause hearing impairment in them.

According to the researchers, babies who were exposed to smoking during pregnancy had a 68 per cent increased relative risk of developing hearing problems.

“This study clearly shows that preventing exposure to tobacco smoke during pregnancy and postnatally may reduce the risk of hearing problems in children,” said Koji Kawakami from the Kyoto University in Japan.

The study, published in the journal Pediatric and Perinatal Epidemiology, included data from 50,734 children aged 3 years.

Out of the group, 3.8 per cent were exposed to smoking only during pregnancy, 3.9 per cent were exposed only to second-hand smoke at 4 months and 0.9 per cent were exposed to tobacco smoke during pregnancy and at 4 months.

The results showed that the prevalence of hearing impairment among babies aged three who were exposed to smoke was 4.6 per cent while those exposed to only second-hand smoke at 4 months had a 30 per cent increased relative risk.

“The findings remind us of the need to continue strengthening interventions to prevent smoking before and during pregnancy and exposure to second-hand smoke in children,” Kawakami added. (IANS)
