Description of intervention(s) / exposure
New Standard Operating Procedure on how to run peripheral vasopressors safely
-Using peripheral Cannulae in the arms or below the knees
-Must be <5cm long
-Infusing Adrenaline or Noradrenaline via pump or syringe driver (B-Braun)
-Treatment as felt indicated by treating retrieval clinician in liaison with retrieval co-ordinator
-Duration of treatment recorded as arrival of team with patient to handover at receiving facility, so includes ground, air and any road legs to transfer.
-Complications followed out to 24 hours post handover at receiving
-Infusions will be run per protocol involving dedicated lines, regular line obs and guidance on site and type of canula and patency checks prior to use.

Guideline based on internal audit data and literature, was an update on last 2016 guideline. It will be attached to this document and available.

Due to the configuration on pumps, initial recording will be in mcg/min, audit range for this was 1-50mcg/min with medians for adrenaline and noradrenaline peripherally of around 12mcg/min. As this study includes children mcg/kg/min will also be provided in write up based on known patients weights also collected.

Compliance is asked with tick box questions in the data collection page. Adverse events are investigated via internal and external governance and adherence to the guideline would be part of any investigation.

Care based on updated SOP and education from retrospective study was planned to be reaudited with a new data capture page dedicated to peripheral vasopressors as specific questions related to it.
This new data capture became live on 1st April 2022. Data from this prospectively collected cohort will be included in the analysis from 1st April onwards. Full ethics was received on 18/7/22 and at that stage 116 patients had already been captured

Outcomes
Primary outcome [1] 330465 0
Complications of peripheral vasopressors graded by severity and type
Tissue
-minor: skin reactions requiring no treatment
-moderate: any reaction requiring topical or infiltrative treatment
-severe: any reaction with tissue loss requiring debridement or surgical intervention
Operational
Minor: line kinks/disconnects with pressure alarms but no hypotension
Moderate: line kinks/disconnects with hypotension or delayed recognition
Severe: Line dislodged requiring transfer to another line or any prolonged >5 minute hypotension due to peripheral vasopressor

outcome is assessed by data linkage to medical records using a mix of medical and nursing notes, skin assessments as part of this and any operation notes and clinical photography will give a good assessment of any complications.
Timepoint [1] 330465 0
within 24 hours of transport
Secondary outcome [1] 406323 0
- What is the complication rate in the use of peripheral vasopressors in this population?
o Including: What is the incidence of complications up to 24 hours post retrieval to destination hospital
o What are the types of complication: local, systemic etc, also stratified by harm: no treatment required but evidence of extravasation, minor morbidity (ie skin necrosis), major morbidity (tissue damage requiring debridement, systemic hypotension with associated complications)
o What treatment is required to manage complications, both immediately and within the first 24 hours in hospital post retrieval
- What sites and types of access are used
- Which monitoring is used: invasive or non-invasive blood pressure, whilst on peripheral vasopressors
- What are the indications for peripheral vasopressor use
- What is the dosage and peak doses of peripheral vasopressors

data is collected via data linkage to medical records
Timepoint [1] 406323 0
during transit

Statistical methods / analysis
Previous literature from ED and ICU has shown complications of 2-7% and internal audit has shown rates of 3.7-5%.
A sample size of 400 was chosen in order to be able to achieve a 80% power for an alpha of 0.05 comparing a 7% event at upper limit with our reported of 3.7%.
