“…The sample size ranged from one to four infants with a median of four infants. The mean GA varied between studies from 28 to 31.25 weeks and the mean birth weight varied from 1,280 to 1,495.5 g. Two studies only reported inclusion criteria instead of mean values for GA and birth weight ( 19 , 22 ). In one study, aminophylline was administered during the study, which started 7 days after birth ( 23 ).…”

“…Heavy workload and alarm fatigue might have a negative influence on prompt and adequate treatment of apneas ( 18 ). The longer the delay in response time, the longer the total duration of apnea and the lower the peripheral oxygen saturation (SpO 2 ) values ( 19 ). Also, administration of tactile stimulation increases the risks of infection due to cross-contamination and will interrupt sleep, which can be disadvantageous for the growth and development of the infant ( 20 ).…”

Effect of Tactile Stimulation on Termination and Prevention of Apnea of Prematurity: A Systematic Review

et al. 2018

Apnea of prematurity (AOP) is one of the most common diagnoses in preterm infants. Severe and recurrent apneas are associated with cerebral injury and adverse neurodevelopmental outcome. Despite pharmacotherapy and respiratory support to prevent apneas, a proportion of infants continue to have apneas and often need tactile stimulation, mask, and bag ventilation and/or extra oxygen. The duration of the apnea and the concomitant hypoxia and bradycardia depends on the response time of the nurse. We systematically reviewed the literature with the aim of providing an overview of what is known about the effect of manual and mechanical tactile stimulation on AOP. Tactile stimulation, manual or mechanical, has been shown to shorten the duration of apnea, hypoxia, and or bradycardia or even prevent an apnea. Automated stimulation, using closed-loop pulsating or vibrating systems, has been shown to be effective in terminating apneas, but data are scarce. Several studies used continuous mechanical stimulation, with pulsating, vibrating, or oscillating stimuli, to prevent apneas, but the reported effect varied. More studies are needed to confirm whether automated stimulation using a closed loop is more effective than manual stimulation, how and where the automated stimulation should be performed and the potential side effects.

“…O estímulo vibratório obteve sucesso em 56% das tentativas de reversão das apnéias. 12 No presente estudo, foram utilizados somente dois parâmetros fisiológicos a FP e a SpO2, que se mostraram eficazes nesta detecção. A tecnologia proposta pode gerar vantagens, por utilizar, somente, o oxímetro de pulso para a detecção da apnéia, um equipamento rotineiramente incorporado no manejo da apnéia nas terapias intensivas em nosso meio, agregando um novo valor tecnológico, quando acoplado ao sistema de reversão da apnéia.…”

RESUMO: Trata-se de um estudo de desenvolvimento e avaliação de um sistema de detecção e interrupção do episódio de apnéia da prematuridade no recém-nascido pré-termo, utilizando o estimulo vibrotátil para reversão. O sistema foi testado em quatro recém-nascidos pré-termos, em 18 episódios apnéicos observados diretamente nas unidades de terapia intensiva. Para interromper a apnéia o mesmo recém-nascido foi submetido, distintamente, ao estímulo manual e vibratório em 250Hz por quatro segundos. Os dados foram tratados por estatística descritiva. O método de detecção da apnéia mostrou-se satisfatório e o método de interrupção da apnéia por estímulo vibratório promoveu o retorno dos movimentos respiratórios, em nove das 10 apnéias. A tecnologia desenvolvida e testada embora demande continuidade de estudos, vislumbra uma tecnologia promissora para a melhoria da qualidade assistencial em neonatologia. DESCRITORES:Apnéia. Prematuro. Tecnologia em saúde. DEVELOPMENT OF A TECHNOLOGY FOR THE DETECTION AND INTERRUPTION OF PREMATURE APNEA EPISODESABSTRACT: This is a study of the development and evaluation of a system to detect and interrupt premature apnea episodes in newborn pre-terms, using vibrotactile stimulus as reversal. The system was tested in four preterm newborns involving 18 directly observed apnea episodes in the intensive care units. In order to stop apnea, the newborn was submitted, separately, to manual stimulus and guide vibration at 250Hz by four segundos. The data was analyzed with descriptive statistics. The method of apnea detection was shown to be satisfactory and the method of interrupting sleep apnea through vibratory stimulation promoted the return of respiratory movements in nine of 10 apneas. The technology developed and tested, while it demands continuity of studies, gleams a promising technology for improving the quality care in neonatology. DESCRIPTORS:Apnea. Premature.

“…The more the response time is extended, the more difficult it is to stop the episode of AB leading to significant problems and consequences that may be irreversible. The average response time delay, measured from the activation of the alarm until the application of the therapy, was estimated around 33 s, with an average of 13 s of tactile stimulation for the AB event suppression (Pichardo et al 2003). Hence the algorithm that activates the alarm has a crucial role in the early detection of respiratory arrest.…”

Apnea bradycardia (AB) is an outcome of apnea occurrence in preterm infants and is an observable phenomenon in cardiovascular signals. Early detection of apnea in infants under monitoring is a critical challenge for the early intervention of nurses. In this paper, we introduce two switching Kalman filter (SKF) based methods for AB detection using electrocardiogram (ECG) signal.The first SKF model uses McSharry's ECG dynamical model integrated in two Kalman filter (KF) models trained for normal and AB intervals. Whereas the second SKF model is established by using only the RR sequence extracted from ECG and two AR models to be fitted in normal and AB intervals. In both SKF approaches, a discrete state variable called a switch is considered that chooses one of the models (corresponding to normal and AB) during the inference phase. According to the probability of each model indicated by this switch, the model with larger probability determines the observation label at each time instant.It is shown that the method based on ECG dynamical model can be effectively used for AB detection. The detection performance is evaluated by comparing statistical metrics and the amount of time taken to detect AB compared with the annotated onset. The results demonstrate the superiority of this method, with sensitivity and specificity 94.74[Formula: see text] and 94.17[Formula: see text], respectively. The presented approaches may therefore serve as an effective algorithm for monitoring neonates suffering from AB.
