Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Chest physiotherapy (CPT) will form the intervention that will be measured in this study. CPT will consist of a combination of techniques including positioning, cupping, expiratory flow increase techniques such as expiratory vibes and sustained expiratory manoeuvres, and endotracheal suction. Treatments will not be standardised. Instead, they will be individualised to each infant’s assessment findings and presentation to reflect clinical reality. All CPT interventions in the study will be performed by a paediatric physiotherapist trained to work in the NCCU. CPT will occur in the NCCU at the infant's bedside as per usual practice in our unit. The techniques, dosing and position utilised during the CPT intervention will be determined by the physiotherapist based on the presence/ type of pathology seen on chest radiograph (CXR), auscultation findings and LUS findings. This is based on current practice in the NCCU where the research project will take place. No published guidelines or practice recommendations are available in the literature due to the lack of previous research undertaken regarding CPT in the neonatal population. A single episode of CPT intervention will be measured, however infant's may be eligible to be measured on more than one occasion, ie. on multiple consecutive days, providing they meet the inclusion criteria. CPT will continue for as many days as indicated (no maximum time frame), based on the physiotherapist's clinical interpretation of assessment findings (CXR, auscultation and LUS). There is no limit on the age of infants being eligible for this research study if they meet inclusion criteria and are receiving care in the NCCU. CPT effects will be measured using Lung Ultrasound (LUS), auscultation, physiological measurements and where available CXR by comparing baseline/ pre-CPT measurements with immediately post, and 4 hours post, CPT measurements. CPT will be undertaken by the physiotherapist and documented in the infant's medical notes and details of the treatment will be documented as part of the study report form. As CPT will be undertaken only by the physiotherapist, not by any other staff members, no adherence strategies will be required.

Outcomes
Primary outcome [1] 339655 0
Change in lung collapse on Lung Ultrasound (LUS)
Timepoint [1] 339655 0
LUS and LUS score will be completed immediately prior to undertaking CPT intervention, again immediately after completion of CPT intervention, and again at 4 hours after completion of CPT intervention.
Secondary outcome [1] 440763 0
Change in auscultation score
Timepoint [1] 440763 0
Auscultation, and auscultation scores, will be collected immediately prior to CPT, immediately after CPT and again at 4 hours post CPT.
Secondary outcome [2] 440764 0
Change in CXR score (if available as part of medical care) with CXR score being a measure of the extent of lung collapse/ how much lung is collapsed, as per the categorization below in Assessment method
Timepoint [2] 440764 0
CXR scores will be made using the most recent formally reported CXR prior to these time points and the details of these CXR will be documented.
Secondary outcome [3] 440971 0
Changes in set Tidal volume or Inspiratory pressure (depending on whether infant is ventilated on a volume mode or a pressure mode)
Timepoint [3] 440971 0
Tidal volume/ set inspiratory pressure be collected immediately prior to CPT, immediately after, and at 4 hours post CPT
Secondary outcome [4] 440972 0
Changes in Fraction of inspired oxygen (FiO2)
Timepoint [4] 440972 0
FiO2 will be recorded immediately prior to CPT, immediately after CPT and at 4 hours after the completion of CPT
Secondary outcome [5] 440973 0
Changes in oxygen saturations (SpO2)
Timepoint [5] 440973 0
SpO2 will be recorded immediately prior to CPT, immediately after CPT and at 4 hours after the completion of CPT
Secondary outcome [6] 440975 0
Changes in transcutaneous carbon dioxide level (TCO2) where available (if being used with infant at the time of CPT)
Timepoint [6] 440975 0
TCO2 will be recorded immediately prior to CPT, immediately after CPT and at 4 hours after the completion of CPT
