Heart rate monitoring is the predominant quantitative health indicator of a newborn in the delivery room. A rapid and accurate heart rate measurement is vital during the first minutes after birth. Clinical recommendations suggest that electrocardiogram (ECG) monitoring should be widely adopted in the neonatal intensive care unit to reduce infant mortality and improve long term health outcomes in births that require intervention. Novel non-contact electrocardiogram sensors can reduce the time from birth to heart rate reading as well as providing unobtrusive and continuous monitoring during intervention. In this work we report the design and development of a solution to provide high resolution, real time electrocardiogram data to the clinicians within the delivery room using non-contact electric potential sensors embedded in a neonatal intensive care unit mattress. A real-time high-resolution electrocardiogram acquisition solution based on a low power embedded system was developed and textile embedded electrodes were fabricated and characterised. Proof of concept tests were carried out on simulated and human cardiac signals, producing electrocardiograms suitable for the calculation of heart rate having an accuracy within ±1 beat per minute using a test ECG signal, ECG recordings from a human volunteer with a correlation coefficient of ~ 87% proved accurate beat to beat morphology reproduction of the waveform without morphological alterations and a time from application to heart rate display below 6 s. This provides evidence that flexible non-contact textile-based electrodes can be embedded in wearable devices for assisting births through heart rate monitoring and serves as a proof of concept for a complete neonate electrocardiogram monitoring system.

Preterm infants are babies who are delivered before the completion of 37 weeks gestation period. They are born with immature functioning of the brain. In  Neonatal Intensive Care Unit (NICU), these infants receives many environmental stimuli, and their comfort will be disturbed. These various sensory stimulus received in NICU influence the functional and neurodevelopmental outcome of these infants and also their quality of life. So this study was intended to evaluate the axillary temperature, heart rate, respiratory rate and oxygen saturation level of these infants prior to nesting and after nesting at the 60th minute. Forty preterm infants who fulfilled the criteria of selection were included in the study by simple random sampling and segregated into case and control groups by blocked randomization. Data was collected and recorded. The temperature was recorded by a digital thermometer, respiratory rate was counted by the number of times the infants' chest rises, heart rate and oxygen saturation readings from the pulse oximeter. The result of the study showed that there was statistically significant effect of nesting at 60th minute, temperature (t=5.03966,p<0.05), respiratory rate(t= -2.13,p<0.05) and heart rate (t=-2.59766,p<0.05). But the effect was not significant on oxygen saturation level (t=1.2,p=0.238).  Hence this study result supports the use of nesting in NICU.

The resuscitation of a neonate in the emergency department is an infrequent occurrence. As such, it is imperative that emergency physicians are aware of the resources available at their institution in the event that resuscitation arises. The two mainstays of neonatal resuscitation are respiration and temperature. When resuscitation is required, it is due to a respiratory cause in the majority of neonates. Therefore, if the airway and breathing are managed properly, the heart rate and overall neonatal status will follow suit. Should the neonate’s heart rate continue to be below 60 beats per minute, then he or she will need chest compressions in addition to respiratory support. During the transition from intrauterine life to extrauterine life, neonates stand to lose substantial amounts of heat. Therefore, the temperature of the neonate also needs to be actively managed to prevent the loss of heat. The resuscitation will eventually end in one of two pathways: the termination of efforts or the successful resuscitation of the neonate. If the resuscitation is successful, the proper admission or transfer will need to be arranged for definitive care for the neonate. Figures include the review of fetal and neonatal circulation, proper use of equipment, and proper chest compression technique. Tables include equipment needed, Apgar scores, normal neonatal vital signs, disposition, and neonatal intensive care unit levels. Key words: Apgar scores, fetal circulation, neonatal chest compressions, neonatal circulation, neonatal resuscitation, neonatal intensive care unit levels
