Description of intervention(s) / exposure
The Kangaroo feeding tube with IRIS technology placed post-pylorically in critically ill patients. In the ICU, as per standard care patients are assessed to determine whether there is a clinical requirement for post-pyloric feeding. To facilitate this, standard care dictates that a small feeding tube (i.e the Kangaroo feeding tube with IRIS technology), be inserted in the small intestine. This may be clinically indicated for a number of reasons, including large gastric residual volumes and decreased gastric motility.

This study will be observing the success rate of the Kangaroo feeding tube with IRIS technology insertion, and no intervention outside of standard care will be carried out.

The tube will be inserted by an ICU clinician once in each participant, and will remain in place as long as a post-pyloric feeding tube is clinically indicated in the participant. Once removed, the tube will only be reinserted if required in the opinion of the treating clinican. Study observation will only occur during insertion of the feeding tube (typically 30 minutes to one hour).

The Kangaroo feeding tube with IRIS technology has a 3mm camera integrated within the tip that transmits images to a visual display. The picture quality is similar to the resolution obtained with the iPhone camera. The tube is single use, disposable, and has TGA approval for the intended purpose of ‘administration of nutrition, fluids and medications for patients who have an intact gastrointestinal tract but are physically unable to manage nutritional intake through normal mastication and deglutition'.

The device has the potential to be superior to both the ‘blind’ placement of gastric tubes, and the endoscopic placement approach to post-pyloric tube insertion because it may facilitate more rapid placement, and the visualisation feature may diagnose certain occult gastrointestinal pathologies (e.g. ulceration), with fewer contraindications. Furthermore, direct visualisation of duodenal placement may eventually obviate the need for radiological confirmation (abdominal x-ray ~0.7mSv) as is current practice not only with 'blind' placement of gastric tubes but also endoscopically placed small intestinal catheter tubes.

Outcomes
Primary outcome [1] 318697 0
Successful rate of insertion of Kangaroo tube with IRIS technology by established users (>= 5 previous attempts).
This will be determined by clinician at the time of insertion. An abdominal x-ray will only be performed to confirm insertion if required in the clinician's opinion. A de-identified image of the lumen will also be taken at the completion of insertion. This will be stored, encrypted, and reviewed in block by an experienced endoscopist who will confirm successful insertion.
Timepoint [1] 318697 0
At time of insertion.
Secondary outcome [1] 365754 0
Time taken to insert Kangaroo feeding tube with IRIS technology.
This will be determined by clinician at the time of insertion using a time-measuring device (i.e. clock).
Timepoint [1] 365754 0
At time of successful insertion.
Secondary outcome [2] 365756 0
Evaluation of whether there is a 'learning curve' associated with using the device (comparing intra-individual success of the first 4 insertion attempts to subsequent attempts).
Successful insertion will be confirmed by clinician at the time of insertion (abdominal x-ray confirmation only performed if required in the opinion of clinician), as well as by experienced endoscopist (using encrypted, de-identified images of participants lumen, sent in block). The success of each individuals first 4 insertion attempts will then be compared to the success of their subsequent attempts, to determine whether a 'learning curve' exists (i.e. operators progressively attaining a higher proportion of successful attempts at insertion as they gain experience).
Timepoint [2] 365756 0
At completion of the study.

Eligibility
Key inclusion criteria
Critically-ill patients admitted to the ICU who:
- require enteral feeding
- are suitable to have a small intestinal feeding catheter inserted
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
In the opinion of the treating clinician, there is a medical condition or concern that means that the patient would not be suitable for a post-pyloric tube, or there is a contraindication to post-pyloric tube placement.

Statistical methods / analysis
We will collect usage for all insertions. The first four insertions will be considered the 'learning phase'. Data for insertion 5 and onward will be used toward the primary outcome, but we will compare success in experienced users to their success in the 'learning phase'. Data from 15 insertions at 5 centres will provide us with a reasonable evaluation of this technique.

We will summarise data using descriptive statistics and include frequency (95% confidence intervals) and time taken (median [IQR]).
