Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention: 3fr, 4fr (outer lumen midline size); power injectable midline catheter. Catheter size chosen by the operator inserting the device.
A midline catheter begins its insertion in a peripheral vein in the upper arm. Midlines are shorter devices and the tip of the midline terminates at the axilla. Xray is not required to check catheter tip position.

All catheters will be inserted by and appropriately trained anaesthetic consultant, registrar, fellow or nurse practitioner in vascular access. All care and maintenance will be performed by appropriately trained nurses in the clinical area.
All catheters will remain in place for the period of treatment between 12-21 days.
Where a device is complicated by failure and a replacement device is required the same device will be reinserted if the patient and substitute decision maker are agreeable.

Treatment: Devices
Comparator / control treatment
Arm 1 - (Control): 3fr, 4fr (outer lumen size) Peripherally Inserted Central Catheter (PICC). PICCs begin their insertion at a peripheral vein in the upper limb and are advanced into a more central position, i.e. cavo-atrial junction. X-ray is usually required to ensure the tip of the catheter is in the right position.

Statistical methods / analysis
All randomised patients will be analysed by intention to treat, irrespective of treatment. The patient is the unit of measurement with one device per patient being analysed. For this pilot trial, we will test the feasibility of the trial by using the criteria defined for the Primary outcome. Logistic regression will be used to compare percentage of patients requiring a general anaesthesia for insertion of midline, in comparison to peripherally inserted central catheters (PICC)s, for children requiring pulmonary optimisation. Univariable analysis will include group, baseline patient and device characteristics, and potential confounders. Rates of anxiety and difficulty will be compared between the groups using Independent samples t-tests.
Qualitative data will be thematically analysed using the procedures outlined by Braun and Clarke. Qualitative analysis will be conducted using Grounded Theory. Comparative cost-analysis will be assessed by health economist considering; purchase price, staff time, operating room costs, inpatient bed days and costs of treating complications or re-insertion of device if necessary.

Summary
Brief summary
Children with respiratory illness including CF and non CF bronchiectasis are the largest cohort of children requiring PICCs at Queensland Children's Hospital (QCH). Traditionally PICCs require a general anaesthesia to establish procedural compliance. Midlines are also used internationally to administer intravenous antibiotics without necessitating general anaesthesia. We hypothesise that the need for GA will be reduced in this patient cohort whilst still providing the necessary treatment. This will benefit this patient population and the healthcare institution through reduced procedural risk and corresponding respiratory compromise, as well as reduced costs associated with theatre personnel. . The primary aims of this research is 1) to evaluate the feasibility of launching a full-scale efficacy trial, using pre-defined feasibility criteria for recruitment, retention and protocol fidelity and 2) need for general anaesthetic.
