SIDS link: Low blood pressure in preterm infantsDecember 08, 2008Monash University scientists show low blood pressure in premature babies during sleep Scientists from Monash University, Melbourne have shown that infants born prematurely have lower blood pressure during sleep in the first six months of life, compared to healthy, full-term infants. Scientists at the Ritchie Centre for Baby Health Research, Monash Institute of Medical Research, believe this may be one reason premature infants are at an increased risk of Sudden Infant Death Syndrome (SIDS). Chief Investigator, Associate Professor Rosemary Horne, said that previous studies have shown that prematurely-born babies are at a significantly increased risk of SIDS; approximately 20 percent of all SIDS cases occur in preterm babies, though preterm babies comprise only 8-10 percent of infants born. "It has been hypothesised that the underlying mechanism of SIDS involves a fall in blood pressure during sleep combined with a failure of the baby to arouse from sleep which would normally restore blood pressure," Associate Professor Horne said. "Our study has now provided evidence as to why preterm babies are at a higher risk for SIDS." The study monitored the blood pressure of 25 preterm and 20 full-term infants at two to four weeks; two to three months and five to six months. Blood pressure was lower during sleep in the preterm infant group at all ages studied, but was lowest in the two to three month age group, when the risk of SIDS is highest. "Our recommendation is that additional research needs to be undertaken to determine whether preterm infants also have impaired cardiovascular control, as this may also contribute to the higher rate of SIDS in preterm infants, particularly when sleeping face down/on the stomach," said Associate Professor Horne. "Parents of both term and preterm infants should follow the advice of SIDS and Kids for infant safe sleeping practices and always sleep their infant on his/her back, keep their baby away from cigarette smoke and ensure that the baby's head cannot be covered by bedding," she said.

Magazines for women depict babies in unsafe sleep environments More than one third of photos in women's magazines depicted babies in unsafe sleep positions, according to a new study in Pediatrics. Was SIDS the cause of infant deaths even 150 years ago? 19th century infant deaths attributed to smothering and overlaying, by either a co-sleeper or bedding, were in all likelihood crib deaths, or Sudden Infant Death Syndrome (SIDS). Simple drug treatment may prevent nicotine-induced SIDS: Study A new study has identified a specific class of pharmaceutical drugs that could be effective in treating babies vulnerable to Sudden Infant Death Syndrome (SIDS), because their mothers smoked during pregnancy. Blood tests reveal tobacco smoke residues in non-smoking New Yorkers More than half of non-smoking New Yorkers have elevated levels of cotinine in their blood - meaning that they were recently exposed to toxic second-hand smoke in concentrations high enough to leave residues in the body. Pregnancy and tobacco a 'smoking gun' for baby: Study Monash University researchers have shown that babies born to a mother who smokes are more likely to be slower to wake or respond to stimulation - and this may explain their increased risk of Sudden Infant Death Syndrome (SIDS). Maternal smoking may alter the arousal process of infants, increasing their risk for SIDS A study in the April 1 issue of the journal SLEEP shows that maternal smoking is associated with an impaired infant arousal process that may increase the risk for sudden infant death syndrome (SIDS). The authors suggest that maternal smoking has replaced stomach sleeping as the greatest modifiable risk factor for SIDS. New study identifies risk factors in severity of 'flat head syndrome' in babies A new study by physician researchers from Hasbro Children's Hospital and Children's Hospital Boston identifies risk factors for the severity of asymmetrical head shapes, known as deformational plagiocephaly (DP), or more commonly as flat head syndrome. The study was published in the March 2009 edition of the Journal of Craniofacial Surgery. OHSU School of Dentistry team discovers new molecule in blood-pressure control system Researchers at Oregon Health & Science University's School of Dentistry (www.ohsu.edu/sod) have discovered that the nerve cells controlling heart rate and blood pressure synthesize a molecule known to be critically important for proper nervous system growth. Studies link maternity leave with fewer C-sections and increased breastfeeding Two new studies led by researchers at the University of California, Berkeley, suggest that taking maternity leave before and after the birth of a baby is a good investment in terms of health benefits for both mothers and newborns.
