The purpose of this study is to determine, in preterm infants less than 37 weeks gestation with respiratory distress who are ventilated in the first 48 hours after birth, if mid frequency ventilation strategy using ventilator rate of ≥ 60 to ≤ 150 per minute compared with standard frequency ventilation strategy using ventilator rates of ≥ 20 to < 60 per minute will increase the number of alive ventilator-free days after randomization and reduce the risk of ventilator induced lung injury.
Acute respiratory distress syndrome in neonates has been defined in 2015. Earlier identification and successful intervention into the potential pregnancy associated risk factors for the conversion from NRDS to ARDS is one of the most important components of ARDS prevention.
This is a quality improvement study with the purpose of observing and measuring the effects of implementation of a proven standardized lung protective ventilation protocol in the new electronic medical record system iCentra across all Intermountain Healthcare hospitals. Approximately 14,000 records will be accessed for this study from a database of mechanically ventilated patients established for quality improvement purposes. The investigators hypothesize that implementation of a standardized computerized lung protective ventilation protocol across all Intermountain Healthcare hospitals will be feasible, will decrease initial tidal volumes to the target 6 ml/kg PBW, and will improve outcomes. The objectives of this study are to: - Determine if the implementation of lung protective ventilation (with a 6 ml/kg PBW tidal volume ventilation protocol on initiation of mechanical ventilation) improves outcomes in patients with acute respiratory failure requiring mechanical ventilation - Determine if the implementation of lung protective ventilation (with a 6 ml/kg PBW tidal volume ventilation protocol on initiation of mechanical ventilation) improves outcomes in the sub-group of patients with the acute respiratory distress syndrome (ARDS) - Measure compliance with the implementation of a computerized lung protective ventilation protocol at 12 Intermountain Healthcare hospitals
Acute respiratory distress syndrome (ARDS) in neonates has been defined, the role of surfactant is not clear. This study aimed to determine whether ARDS neonate would benefit from surfactant when oxygenation deteriorated on mechanical ventilation and to identify any potential risk factors related to mortality.
Continuous distending airway pressure (CPAP) has gained popularity as a means to provide non-invasive respiratory support in neonates to reduce ventilator induced lung injury (VILI). However, maintaining CPAP in preterm infants has been challenging, often related to issues with nasal interface such as nasal septal injury, problems with keeping the prongs in the nose and leak around the prongs with are important factors in proving effective CPAP. RAM cannula was recently approved for providing supplemental oxygen and soon adapted by many centers to provide CPAP in preterm infants. Concerns have been raised that RAM cannula interface results in sub-optimal pressure delivery compared to standard nasal prongs.
The investigators compared advantages and disadvantages of two forms of noninvasive respiratory support -noninvasive high-frequency oscillatory ventilation (nHFOV) or nasal continuous positive airway pressure (nCPAP) -as a primary mode of ventilation in preterm twins infants with respiratory distress syndrome
The goal of this interventional crossover study, in intubated and mechanically ventilated Acute Respiratory Distress Syndrome (ARDS) patients, is to compare two positive end-expiratory pressure (PEEP) titration techniques regarding: respiratory mechanics, gas exchange, changes in aeration, ventilation/perfusion matching its impact on cardiac function, especially the right heart (RH). The PEEP titration techniques are: PEEP selection based on low PEEP/high FiO2 table ("PEEPARDSnet") and lung recruitment maneuver (LRM) plus PEEPdec titration based on the best compliance of the respiratory system("PEEPLRM").
Respiratory distress syndrome (RDS) is the main cause of respiratory failure in preterm neonates, its incidence varying from 80% to 25% depending on gestational age.When optimal prenatal care is provided, the best approach to treat RDS, according to several recent trials,consists in providing continuous positive airway pressure (CPAP) from the first minutes of life using short binasal prongs or masks, followed by early selective surfactant administration for babies with worsening oxygenation and/or increasing work of breathing. Any effort should be done to minimize the time under invasive mechanical ventilation (IMV).Nonetheless, clinical trials have shown that a relevant proportion of preterm neonates fails this approach and eventually need IMV.The duration of IMV is a well known risk factor for the development of broncho-pulmonary dysplasia (BPD) - a condition associated with significant morbidity and mortality. To minimize the duration of IMV, various non invasive respiratory support modalities are available in neonatal intensive care units (NICU). CPAP is presently the most common technique used in this regard. However, a systematic review has shown that non-invasive positive pressure ventilation (NIPPV) reduces the need for IMV (within one week from extubation) more effectively than NCPAP, although it is not clear if NIPPV may reduce need for intubation longterm and it seems to have no effect on BPD and mortality. NIPPV main drawback is the lack of synchronization, which is difficult to be accurately achieved and is usually unavailable. A more recent alternative technique is non-invasive high frequency oscillatory ventilation (NHFOV) which consists on the application of a bias flow generating a continuous distending positive pressure with oscillations superimposed on spontaneous tidal breathing with no need for synchronization. The physiological, biological and clinical details about NHFOV have been described elsewhere. To date, there is only one small observational uncontrolled study about the use of NHFOV after extubation in preterm infants. Other relatively small case series or retrospective cohort studies suggested safety, feasibility and possible usefulness of NHFOV and have been reviewed elsewhere.The only randomized trial published so far compared NHFOV to biphasic CPAP,in babies failing CPAP and it has been criticized for methodological flaws and for not taking into account respiratory physiology.An European survey showed that, despite the absence of large randomized clinical trials, NHFOV is quite widely used, at least in some Countries and no major side effects are reported, although large data about NHFOV safety are lacking. This may be due to the relative NHFOV easiness of use but evidence-based and physiology-driven data are warranted about this technique.
In very preterm infants with severe respiratory distress syndrome(RDS), invasive ventilation(IV) , besides nasal continuous positive airway pressure (NCPAP) and early/selective pulmonary surfactant administration, is one key cornerstone to reduce neonatal mortality. However, IV is related to increased risks of bronchopulmonary dysplasia (BPD) and abnormal developmental outcomes in the survival.Weaning from IV is therefore a key procedure to reducing these risks above, and if extubation does not success, repeated intubation and/or prolonged duration of IV will result in increased medical burden and intubation-associated complications and death. How to minimize the need for endotracheal ventilation and subsequent complications constitutes a challenge for neonatologists.
