Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will compare the safety and efficacy of two interventions in patients with rib fractures. Both interventions are regional anaesthetic techniques where a continuous infusion of local anaesthetic is delivered to nerves travelling to the ribs, however the catheter will be inserted into different locations.
Arm 1: Erector spinae plane
Arm 2: Paravertebral space
Both will have the same prescription for ongoing local anaesthetic delivery - 10ml/hr 0.2% ropivacaine. All interventions will be performed by consultant anaesthetists, or advanced trainees in anaesthesia who are competent at these types of blocks.

In order to enhance the fidelity of the interventions, the consultant anaesthetists performing the regional nerve blocks are a small group of select consultants who are highly skilled in this area. It is voluntary to allow their patients to be a part of this trial and all consultants taking part believe in the value of high quality research in this area. Wherever possible, the interventions will be supervised by a research team member, and all ongoing prescriptions will be reviewed to ensure they reflect the study protocol prescription in its entirety. Where it is not possible to supervise the intervention (e.g. weekends) it is common practise to record the procedure on the ultrasound machine, and this can be checked by a research team member.

Outcomes
Primary outcome [1] 307918 0
Verbal pain score with 0 meaning no pain at all, and 10 described as the worst pain imaginable.
Timepoint [1] 307918 0
Immediately before and following intervention, and on each subsequent day for one week, or the length of hospital stay (whichever is shorter).
Primary outcome [2] 307919 0
Opioid dose used for each 24 hour period following the intervention as assessed by the total of :
1. Patient controlled analgesia device if applicable
2. Hospital medication chart
Timepoint [2] 307919 0
Each 24 hour period for one week, or length of hospital stay (whichever is shorter)
Primary outcome [3] 307920 0
Spirometry - VC
Timepoint [3] 307920 0
Immediately before and following intervention, and on each subsequent day for one week, or length of hospital stay (whichever is shorter).
Secondary outcome [1] 353351 0
Adverse effects / complication rate such as infections at the site, inadequate analgesia requiring replacement of the catheter, pneumothorax, epidural spread of local anaesthetic etc. These will be assessed and recorded daily by the acute pain management service on review of the patient and their medical chart.
Timepoint [1] 353351 0
Daily for one week or length of hospital stay, whichever is shorter
Secondary outcome [2] 353352 0
Length of hospital stay as assessed by hospital records
Timepoint [2] 353352 0
Length of hospital stay as assessed by hospital records
Secondary outcome [3] 353353 0
Patient satisfaction as rated on a 5 point scale with 0 = not at all satisfied and 5 = extremely satisfied.
Timepoint [3] 353353 0
Daily for one week or length of hospital stay, whichever is shorter
