Conditions

Persistent air-leak Respiratory

Interventions

Autologous blood patch (ABP), Patients randomised to ABP will have 1mg/kg of blood aspirated by appropriately trained clinician. This blood will be then instilled via the drain into the pleural space.

Design outcomes

Primary

MeasureTime frame
The proportion of the total number of patients who are eligible for trial entry who accept randomisation measured using patient records at end of study

Secondary

MeasureTime frame
Measured using patient records (unless noted otherwise): 1. Duration of air-leak in first 90 days 2. Duration of chest drain in-situ in first 90 days 3. Proportion of patients with air-leak cessation 72hours after 2nd intervention 4. Proportion of patients meeting inclusion and exclusion criteria approached by trial team 5. Proportion of patients randomised who receive the first allocated intervention 6. Proportion of patients randomised who receive the second allocated intervention 7. Proportion of patients randomised who complete trial follow-up 8. Pain (using visual analogue score, VAS) and breathlessness (VAS) measured post-intervention, day 7 and at day 90 post-randomisation (±7 days) 9. Patient-reported health status (EQ-5D-5L) measured post-intervention (within 24 hours), day 5 and day 90 post-randomisation (±14 days) 10. To assess patient views and experiences of interventions and study design 11. To assess clinician views of interventions and study design 12. Total number of pleural procedures in first 90 days 13. Length of initial hospital stay (LOHS) in first 90 days 14. Surgical referral and acceptance rates in first 90 days 15. Mortality rates in first 90 days 16. Serious adverse rates in first 90 days
