研究概览
简要总结
In this pilot study, the investigator team aims to evaluate whether standardized prone positioning compared to usual positioning improves moderate to severe bronchopulmonary dysplasia (BPD) rates as assessed at 36 weeks post conceptional age in very low birth weight preterm infants with bronchopulmonary dysplasia.
详细描述
The investigator team aims to enroll and randomize infants born at less than 1500 grams at birth, who remain on positive pressure support for at least 7 days after birth AND/OR on any other respiratory device such as nasal cannula with flow rates greater than 2 liters per minute (LPM) receiving supplemental oxygen of greater than 21% for at least 7 days after birth.
Patients whose families consent to participation will be assigned via block randomization to
- usual care in which positioning and duration in each position is random per usual nursing routine OR
- Receive standardized scheduled daily prone positioning starting on day of life 7.
As part of normal developmental care, most infants are evaluated and have care rendered (touch-time), if stable, and repositioned at set three-hour intervals to permit uninterrupted sleep and/or rest. The hands-off interval will be maintained throughout the study interval. Infants randomized to the standardized scheduled daily prone positioning will be placed in prone body position for a total of 6 hours daily, that is prone position for 3 hours, followed by supine positioning for 3 hrs, then placed in prone position for another 3-hour interval. Both infants randomized to standardized prone positioning and usual positioning will have a bedside card identifying that the infant is a study participant and will serve as a way to document the number of times any infant enrolled in the study is placed in prone positioning even if not randomized to standardized prone positioning.
Standardized daily positioning will occur for randomized patients until 36 weeks or discharge whichever is first. The primary outcome of moderate or severe BPD will be assigned by blinded study personnel based on respiratory support parameters on the day the infant is 36 weeks postconceptional age.

入选标准
- •infants born at less than 1500 grams at birth, who remain on positive pressure support for at least 7 days after birth AND/OR on any other respiratory device such as nasal cannula with flow rates greater than 2LPM receiving supplemental oxygen of greater than 21% for at least 7 days after birth. Positive pressure for the purposes of this study is defined as nasal cannula delivering a flow of 2 LPM or higher, continuous positive airway pressure (CPAP), non-invasive positive pressure ventilation or non-invasive mechanical ventilation (NIPPV/NIMV), as well infants who are intubated or have a tracheostomy for oxygenation and ventilation related to their lung disease, irrespective of the mode of ventilation.
排除标准
- •infants who were previously on room air without a respiratory device who were intubated for the purposes of surgery and were not receiving respiratory support as defined above prior, those intubated for other airway issues such as tracheal stenosis, broncheo- or tracheomalacia, etc and not for the management of BPD. Additional patients to be excluded include those with suspected or proven genetic or other major congenital anomalies that may impact cardiac and lung function including cardiac and lung anomalies, as well as those at the time of enrollment who require surgeries that will impact their ability to be placed in prone positioning (eg gastroschisis, omphalocele, etc).
研究组 & 干预措施
Prone positioning for a total of 6 hours daily by study protocol
Patients will be positioned prone for 3 hours then placed supine for 3 hours then prone again for 3 additional hours. The change in position from prone to supine and back is to more reliably document possible changes in ventilation, oxygenation, other vital signs and respiratory support required.
干预措施: Prone positioning for a total of 6 hours daily (Other)
usual positioning
Patients in the newborn intensive care unit are physically handled usually every 3-4 hours. Those study participants who are randomly assigned to "usual position" may rest in a variety of positions in any order based on nursing or perceived patient preference. Positions may include supine, right lateral, left lateral, and prone as well.
结局指标
主要结局
Moderate (Grade 2) or Severe (Grade 3) Bronchopulmonary Dysplasia
时间窗: as determined by respiratory support requirements at 36 weeks postconceptional age
The number of infants with either Moderate or Severe Bronchopulmonary Dysplasia (BPD) will be determined per study arm. Moderate and Severe BPD will be defined as follows: Moderate (Grade 2) BPD: If an infant requires nCPAP, NIPPV, HFNC, or NC \> 2 liters per minute flow and receiving \> 21% FiO2. Severe (Grade 3) BPD: If an infant requires invasive positive pressure ventilation via an endotracheal or tracheostomy irrespective of the amount of FiO2.
