Heart Attack Clinical Trials

Aims: * To describe current sedation use in ECMO patients in the UK and compare to non-ECMO critically ill patients. * To develop a sedation protocol for ECMO patients with input from patients, their family, and staff. Design/methods: Study 1: The investigators will study how sedation is used in adult ECMO patients and compare with non-ECMO but critically ill patients in the UK. The investigators will collect information on drug doses and pain and sedation scores. The investigators will also ask ECMO centres if they use a sedation protocol to adjust sedation doses. This information will be helpful for the design of the protocol in study 2. Study 2: The investigators will design a sedation protocol with input from patients, family, and staff. The investigators will organise meetings to share experiences and agree on what to include in the protocol that is considered acceptable and safe. The investigators will then assess if the protocol is safe and acceptable with staff outside the co-design group. Patient and public involvement/engagement: The investigators received feedback from patients and family members which helped to design this proposal, the lay summary and what to measure in a trial. Patients and family members will continue to help with development of the sedation and trial protocol. They will advise how the investigators should review study findings, and support sharing of results to the public. Impact/dissemination: The investigators will share findings through social media, patient charities, research papers and conferences.
