“…Due to neonatal immaturity and developing gastrointestinal systems, preterm infants are more prone to feeding intolerance and necrotizing enterocolitis (NEC). Near-infrared spectroscopy ( 9 ) and intestine ultrasonography ( 10 ) are two non-invasive methods that have been examined for blood flow and motility to observe intestinal movement and aid in the diagnosis of NEC in preterm infants. However, the necessity for expert interpretation and the incapacity of real-time and long-term monitoring restrict their extensive application.…”

ObjectiveBowel dysfunction continues to be a serious issue in neonates. Traditional auscultation of bowel sounds as a diagnostic tool in neonatal gastrointestinal problems is limited by skill and inability to document and reassess. Consequently, in order to objectively and noninvasively examine the viability of continuous assessment of bowel sounds, we utilized an acoustic recording and analysis system to capture bowel sounds and extract acoustic features in term neonates.MethodsFrom May 1, 2020 to September 30, 2020, 82 neonates who were hospitalized because of hyperbilirubinemia were included. For 20 h, a convolutional neural network-based acoustic recorder that offers real-time, wireless, continuous auscultation was employed to track the bowel sounds of these neonates.Results(1) Usable data on five acoustic parameters of bowel sound was recorded for 68 neonates, and the median values were as follows: The rate was 25.80 times/min [interquartile range (IQR): 15.63–36.20]; the duration was 8.00 s/min (IQR: 4.2–13.20); the amplitude was 0.46 (IQR: 0.27–0.68); the frequency was 944.05 Hz (IQR: 848.78–1,034.90); and the interval time was 2.12 s (IQR: 1.3–3.5). (2) In comparison to the parameters of the bowel sounds recorded from the right lower abdomen in 68 infants, the acoustic parameters of the 10 out of 68 infants from chest controls and blank controls were considerably different. (3) The 50%–75% breast milk intake group had the highest rate, the longest duration, and the highest amplitude of bowel sounds, while the >75% breast milk intake group had the highest frequency of bowel sounds. (4) Compared with neonates without hyperbilirubinemia, there was no significant difference in the five parameters of bowel sounds in hyperbilirubinemia infants; nor was there a significant effect of phototherapy and non-phototherapy status on the parameters of bowel sounds during bowel sound monitoring in hyperbilirubinemia patients. (5) A mild transient skin rash appeared on the skin of three infants. No other adverse events occurred.ConclusionThe acoustic recording and analysis system appears useful for monitoring bowel sounds using a continuous, invasive, and real-time approach. Neonatal bowel sounds are affected by various feeding types rather than hyperbilirubinemia and phototherapy. Potential influencing factors and the significance of their application in neonatal intestinal-related disorders require further research.
