Real-world clinical innovation. Structured evaluation. Practical implementation.
Green Anaesthetic Limited is not an academic research institution.
Our focus is different: translating clinical innovation into safe, reproducible procedural sedation pathways that function effectively in real-world healthcare environments.
Meaningful innovation requires more than enthusiasm. It requires:
Our work combines frontline clinical practice with service development, education and real-world pathway design.
In 2021, Dr David Green became the first clinician in the United Kingdom to introduce remimazolam into routine clinical practice. Since then, he has developed one of the UK’s most established real-world remimazolam practices, encompassing more than 1,000 cases drawn from a broader sedation practice of over 5,000 cases across fertility, cardiology and surgical settings.
This work has led to:
Educational presentations have included:
Green Anaesthetic Limited has supported development of a remimazolam-based cardioversion sedation programme within the NHS.
Developed collaboratively with MALUE, the programme evaluates:
The programme is currently expanding into additional centres.
Green Anaesthetic Limited is currently developing proof-of-concept remimazolam sedation and anaesthetic pathways for pulsed field ablation (PFA) procedures in collaboration with Medtronic and clinicians in cardiac electrophysiology.
PFA is one of the fastest-growing areas within interventional cardiology, yet optimal sedation and anaesthetic strategies remain poorly defined.
Current development work focuses on:
Initial structured data collection is expected to commence during 2026.
The goal of every programme is the same: to develop sedation pathways that are clinically safe, operationally efficient and scalable within modern healthcare systems.
