About this study

Official title: Neuromodulation of Limb Proprioceptive Afferents Using a Vibratory Device to Decrease Apnea, Intermittent Hypoxia and Bradycardia of Prematurity.

Purpose of Study: Apnea of Prematurity (AOP) is common, affecting the majority of infants born <34 weeks gestational age (GA). Apnea is accompanied by intermittent hypoxia (IH), which contributes to multiple pathologies, including retinopathy of prematurity (ROP), sympathetic ganglia injury, impaired pancreatic islet cell and bone development, and neurodevelopmental disabilities. Standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and caffeine therapy, none of which is optimal. The objective is to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements facilitate breathing.

Methods Used: Premature infants (23-34 wks GA) with clinical evidence of AOP/IH were enrolled 1 week after birth. Caffeine therapy was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in a 6 hour ON/OFF sequence for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2), and breathing pauses were continuously collected.

Read the detailed description

Aim: To study the effect of limb proprioceptive stimulation using a vibratory device on apneic events, intermittent hypoxic episodes and bradycardias in a premature infant with apnea of prematurity.

The objective is to provide support and to assist impaired ventilation and oxygenation in apnea of prematurity (AOP). Recurrent apnea and accompanying resultant intermittent hypoxic (IH) episodes are significant concerns commonly encountered in premature infants, and optimal management is a challenge to neonatologists. AOP is defined as "a pause of breathing for more than 15-20 seconds or accompanied by oxygen desaturation (SpO2<80% for>4s) and bradycardia (heart rate<2/3 of baseline for>4s), in infants born less than 37 weeks of gestation [Moriette G et al., 2010]. When these pauses are longer (> 15s), they are frequently prolonged by obstructed inspiratory efforts, most likely secondary to loss of upper airway tonic activity [Martin RJ et al., 2012]. In extremely low birth weight (ELBW) infants, the incidence of IH progressively increases over the first 4 weeks of postnatal life, followed by a plateau and subsequent decline between 6-8 weeks.

The incidence of AOP correlates inversely with gestational age and birth weight. Nearly all infants born <29 weeks gestation or <1,000 g [Robertson CM et al., 2009], 54% at 30 to 31 weeks, 15% at 32 to 33 weeks, and 7% at 34 to 35 weeks gestation exhibit AOP [Martin RJ et al]. Both animal and human evidence show that immature or impaired respiratory control and the resultant IH exposure contribute to a variety of pathophysiologic issues via pro-inflammatory and/or pro-oxidant cascade as well as cellular mechanisms, e.g., apoptosis, leading to acute and chronic morbidities (e.g. retinopathy of prematurity, altered growth and cardiovascular regulation, disrupting zinc homeostasis which hampers insulin production and there by predisposing to diabetes in later life, cerebellar injuries and neurodevelopmental disabilities) [Martin RJ et al., 2004, Pae EK et al., 2011, 2014, ].

Current standard of care for AOP includes prone positioning, continuous positive airway pressure (CPAP) or nasal intermittent positive pressure ventilation (NIPPV) to prevent pharyngeal collapse and alveolar atelectasis, and methylxanthine therapy (caffeine, theophylline), which is the mainstay of treatment of central apnea [Reher et al., 2008; Pantalitschka T et al., 2009; Moretti C et al., 2012; Henderson-Smart DJ et al., 2010]. Apart from prone positioning, none of these interventions are optimal for early development. CPAP masks will distort the bony facial structure in early development, and methylxanthine interventions pose serious questions of neural development interactions.

Hypothesis: Applying slight vibration to the limbs will reduce the number of breathing pauses, intermittent hypoxic episodes and bradycardias in apnea of prematurity.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • VibrationDevice

    Also called (no generic name)

    A device providing vibrations is placed on the subject and vibration is turned on and off in a 6 hour on/off sequence. Heart rate, respiratory pauses and oxygen saturation are compared during vibration (intervention) and without vibration (no intervention) in the same subject.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Total Number of Episodes of Apnea/Breathing Pauses During Intervention and Without Intervention

    The total number of apneas/breathing pauses will be compared during periods of vibration (intervention) to periods of no vibrations (no intervention).

    Measured: 12 hours of intervention/12 hours of no intervention

Secondary outcomes (2)
  1. Change in the Total Number of Intermittent Hypoxic Episodes to <90% Lasting >5 Seconds/Episode During the Intervention and Without Intervention

    The total number of intermittent hypoxic episodes to <90% (pulse oximetry) lasting >5 seconds/episode will be compared during periods of vibration (intervention) to periods of no vibrations (no intervention).

    Measured: 12 hours of intervention/12 hours of no intervention

  2. Change in the Total Number of Bradycardia Episodes (<100 Beats Per Minute (Bpm), at Least 5 Seconds Long) During Intervention and Without the Intervention

    The total number of bradycardia episodes to <100 bpm lasting >5 seconds/episode will be compared during periods of vibration (intervention) to periods of no vibrations (no intervention).

    Measured: 12 hours of intervention/12 hours of no intervention

In the same subject there were 2 periods: Arm 1. 'No intervention' period (no vibrations) - two 6 hour epochs - total of 12 hours of 'No intervention' Arm 2. Experimental period (with vibrations) - two 6 hour epochs - total of 12 hours of 'vibration intervention' In the same subjects cardiorespiratory parameters - heart rate, respiratory rate and oxygen saturation were compared during the experimental period (vibration) and druing the no intervention period (no vibration).
