To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
To directly compare pH results of gastric aspirate samples in children receiving enteral feeding with endotracheal aspirate samples in children in intensive care requiring tracheal suctioning over a 6 month period. Particularly to examine potential overlap of pH results between the aspirate samples which is where the cutoff for identification of a misplaced tube would occur. This data can then be used to establish a reliable and clinically practical pH cut-off value for gastric aspirate without risking the safety of the patient by not identifying a misplaced nasogastric tube (NGT) in the lung.
Intervention code [1] 241290 0
Not applicable
Comparator / control treatment
All paediatric intensive care unit (PICU) patients within this age range who required endotracheal suctioning as part of their routine care were recruited to obtain endotracheal aspirate samples for pH testing over a 6 month period
Control group
Uncontrolled

Outcomes
Primary outcome [1] 240925 0
We compare the range of pH results between gastric and endotrachael aspirate samples, with particular interest in the area of overlap between the two samples. This data will help to determine a reliable and practical pH value to confirm NGT placement, without increasing the risk of not identifying a misplaced NGT.
Timepoint [1] 240925 0
Gastric aspirate samples taken prior to administration of enteral feed (minimum once per day to maximum 2 hourly) until NGT is removed over the 6 month period.
Endotracheal aspirate samples collected at every tracheal suctioning procedure for patients in ICU (minimum once per day to maximum 2 hourly) until tracheal suctioning is no longer required as routine care over the 6 month period.
Secondary outcome [1] 257644 0
nil
Timepoint [1] 257644 0
nil

Eligibility
Key inclusion criteria
All patients aged over 4 weeks at the Royal Children's Hospital (RCH) receiving enteral nutrition (nasogastric or gastrostomy) were recruited to the study. In addition, all paediatric intensive care unit (PICU) patients within this age range who required endotracheal suctioning as part of their routine care were also recruited to obtain endotracheal aspirate samples for pH testing.
