Haridas, H., Balasubramanium, R. K., & Bhat, J. S. (2015). Respiratory swallowing coordination in healthy term neonates during the first 4 days of life. Journal Of Laryngology & Voice, 5(2), 39-43. doi:10.4103/2230-9748.183964 Introduction: The purpose of this study is to assess the swallowing and respiration coordination in neonates up to 4 days old, and to investigate their swallowing apnea duration (SAD). SAD is the absence of respiration during swallowing due to the bolus passing through the oropharyngeal region. They are measuring the distribution of the swallows in the infant’s respiratory cycles, which means they are recording when the infant stops breathing to take their swallow. This can happen …show more content…
This is placed at the nostrils of the neonate with the other end connected to the workstation of the instrument. The graph produced traces a line across the screen labeling exhalation as green, inhalation as red, and a horizontal black line representing swallowing. The mothers were seated while feeding their neonates for this study. On average, 8 consecutive swallows were taken from each neonate.
Results/Conclusions:
The results conclude that the mean apnea duration is .702 seconds, with the shortest apnea being .497. Only 2 out of 22 neonates had a swallow that was longer than one second. The most popular suck swallow breath pattern, with 96 swallows recorded, was found to be mid-expiration (EE). The next most common pattern was a swallow at the shift from inspiration to expiration (IE), which was recorded 47 times. Swallowing during the shift from expiration to inspiration (EI) was recorded 25 times. Finally, recorded 8 times, was a mid-inspiration swallow (II) pattern. …show more content…
The experiment should have been conducted with far more than 22 neonates. With such a small sample size, the information from the study would have such a large confidence interval that the measurements taken could not safely assume a neonate would fall within this range. This study also concluded that adults have a longer SAD, which led them to believe that the neonate’s coordination matures as they grow. I believe they should have tested that theory by assessing more than one age group. They could have done twenty-two neonates, twenty-two 2-week-old infants, then a group of 1 month olds to see how quickly this coordination develops. Though the sample size for the study was too small, it sparks further interest into the topic. The better we understand how healthy neonates coordinate their feeding, swallowing, and breathing, the better we can advance our treatment for premature babies with deficiencies in feeding, swallowing and breathing coordination in our field of
