Filter by:The goal of this clinical trial is to answer whether the use of a single loading dose (20 mg/kg) of caffeine citrate one hour before extubation has an impact on the success rate of extubation among preterm neonates. In addition, the investigators would like to assess the frequency of apneas and side effects of the intervention, as well as the development of NEC, BPD, IVH, PVL, and long-term neurodevelopmental outcomes in the investigated populations. According to institutional protocol, preterm infants born before the 32nd week of gestation receive a standard dose of caffeine citrate therapy. This covers a maintenance dose of 5-10 mg/kg of caffeine citrate administered intravenously once or twice daily after a loading dose of 20 mg/kg on the first day of life. In this trial, preterm infants born before the 32nd gestational week and who had been mechanically ventilated for at least 48 hours before planned extubation are planned to be randomly allocated into intervention and control groups. The intervention group will receive an additional loading dose of caffeine citrate 60 minutes before extubation. The control group will receive standard dosing regimens.
The study proposes to complete the development of and then establish the safety, efficacy, and clinical risk/benefit of a novel hospital incubator pad with stochastic vibrotactile stimulation (SVS) that will provide a complementary treatment and the first improvement in the clinical management of apnea of prematurity (AOP) in over 20 years. Currently, the only approved therapy for AOP is Caffeine Citrate. The SVS mattress pad can prove to be an effective, non-invasive adjunct to Caffeine Citrate for preterm infants with potential to shorten the need for respiratory support as well as overall shortened length of stay.
This study aims to assess whether extending the duration of caffeine therapy will help preterm infants achieve full oral feeding faster.
Diagnostic investigations in paediatric respiratory and sleep medicine are often challenging due to patient size (due to prematurity), tolerability, and compliance with "gold standard equipment". Children with sensory/behavioural issues, at increased risk of sleep disordered breathing (SDB), often find tolerating standard diagnostic equipment difficult. There is a need to develop non-invasive, wireless, devices designed for the paediatric population. Devices must address health in-equalities as high-risk children, with low birth weights, genetic syndromes, or complex neuro-disabilities, are often unable to undergo current investigations, particularly in sleep medicine. Prompt and accurate diagnosis of SDB is important to facilitate early intervention and improve outcomes Infants in the neonatal period can have immature breathing control which manifests as excessive central breathing pauses, apnoea's, whilst asleep requiring oxygen therapy. There is also a risk to newborn term infants of sudden unexpected neonatal collapse, even in "low risk" babies. Diagnosis of breathing issues in babies can be challenging since babies are often too small for standard monitoring equipment. Effective monitoring and appropriate treatment of apnoea's has been shown to improve prognosis in terms of 5-year mortality and neurodevelopmental outcomes. This observational study is part of a phased clinical program of research that aims to validate a small wearable biosensor developed by PneumoWave Ltd in a paediatric clinical setting with the overall primary endpoints of monitoring and assessing respiratory pattern as an aid to sleep diagnostics, and as a device to monitor apnoea in neonatal patients.
This research study is being done to investigate the effect of changing an infant's body position on how hard the baby works to breathe, the baby's oxygen level, the baby's carbon dioxide level, the baby's lung volume, the baby's lung compliance (ability of the lung to expand and fill with air), and how frequently the baby develops clinically significant events such as apnea (baby stops breathing on his own), bradycardia (low heart rate), and desaturation (low oxygen) events.
This trial analyzes the effect of an olfactory stimulation with vanilla or strawberry aroma compared to placebo on desaturations and bradycardia in preterm infants with apnea of prematurity. Infants on continuous positive airway pressure (CPAP) support will be included and the aroma will be applied to the inner surface of the CPAP mask using designated scent pens. The trial uses a cross-over design. Infants are randomised to begin the study with either aroma or placebo which will be applied into the breathing mask every 3 to 4 hours during 12 hours for each of the two intervention periods. Identically looking pens with either aroma or placebo are used and patients, parents, medical staff and the study team are blinded to this allocation. Infants are monitored with an oximetry sensor to measure peripheral oxygen saturation (SpO2) and pulse rate.
Caffeine citrate, the first-line agent for apnea of prematurity, enhances diaphragmatic activity. EDI values of neurally adjusted ventilatory assist (NAVA) modes can be used to quantify the diaphragmatic activity triggered by electrical impulse from the respiratory center. This study aims to evaluate the EDI changes following caffeine citrate administration and cessation in preterm infants, and whether such changes are affected by different doses used variably in clinical settings.
The aim of this proposal is to characterize the acute effect of early postnatal sound exposure on neuronal maturation of the respiratory control regions of the brain in preterm infants.
This is an observational, proof-of-concept, feasibility study where 50 preterm infants with gestational age < 32+0 weeks will be recruited from the neonatal intensive care unit (NICU) at the Montreal Children's Hospital. The study's primary objective is to describe the relationship between respiratory acoustics and airflow and determine the reliability of a novel respiratory acoustic sensor at detecting breathing sounds in preterm infants. The study's secondary objectives are: 1. To compare transthoracic impedance, respiratory inductive plethysmography and an inertial measurement unit for the detection of respiratory efforts in preterm infants. 2. To evaluate the feasibility and accuracy of a novel, non-invasive method for continuously detecting and differentiating cardiorespiratory events in preterm infants on CPAP by integrating measurements of respiratory effort with respiratory acoustic monitoring.
Caffeine, a typical representative of methylxanthine, is world-widely used to manage apnea of prematurity (AOP) in neonatology. However, an appropriate medication regimen of caffeine has not been well defined until now. For example, in terms of the duration of caffeine, AAP guideline for AOP (2016) and British NICE guideline for neonatal respiratory care (2019) all recommended discontinuing caffeine when the infants reached a postmenstrual age (PMA) ≥33weeks and had a stable respiratory status, commonly manifested by weaning from non-invasive ventilation and free of apneic episodes for at least five consecutive days. Interestingly, the actual clinical settings seem to be not strictly following this recommendation. A survey of the neonatologist in North America revealed that a substantial variability existed among sites in the timing of caffeine discontinuation before discharge and the respiratory support at the time of caffeine discontinuation [1]. Another survey in Saudi Arabia also had a similar finding [2]. The optimal timing of discontinuing caffeine is still a conundrum in the field of neonatology. Ideally, the optimal timing of discontinuing caffeine should be individual-specific. Published work has indicated that AOP and intermittent hypoxemia (IH) were frequently observed beyond 36 weeks' PMA in all gestational age groups, particularly in the 24- to 27-week infants [3, 4]. In the clinical settings, intermittent hypoxic and AOP episodes is a predominant cause of oxygen supplement in premature infants and commonly prolong the hospital stay. Optimizing arterial saturation by oxygen supplement is essential to achieve a stable cardiorespiratory status because hypoxemia could induce hypoxic sensitivity of the carotid bodies in neonates, resulting in more pronounced ventilatory depression and more frequent apneic episodes. Some RCTs have shown that continuing caffeine administration beyond PMA 34 weeks could reduce the frequency of IH episodes in premature infants [4, 5]. Therefore, theoretically, a prolonged caffeine administration over the usual duration could shorten the duration of oxygen supplements in those infants at high risk of frequent late AOP or IH. Target weaning oxygen could be an opportunistic indicator of discontinuing caffeine. In light of the above considerations, a multicenter, retrospective, partially blinded, controlled trials will be conducted to verify the hypothesis that a novel caffeine regimen that weaning oxygen as the indicator of discontinuing caffeine could improve respiratory outcomes of very premature infants.
