Listening to a recording of a mother's voice and heartbeat reduces the number of cardio-respiratory events among premature babies, a new study published in The Journal of Maternal-Fetal and Neonatal Medicine reveals.
Researchers from Neonatal Intensive Care Unit at Brigham and Women's Hospital (BWH) in Boston conducted the experiment on 14 premature babies born between 26 and 32 weeks of gestation.
The babies were made to listen to a recording of his or her mother's voice and heartbeat for four times a day throughout their stay in the intensive care unit.
The researchers found that the babies were less likely to experience a cardio-respiratory event when listening to this recording compared to when hearing normal hospital sounds. "Our findings show that there may be a window of opportunity to improve the physiological health of these babies born prematurely using non-pharmacological treatments, such as auditory stimulation", lead researcher Amir Lahav said.
