Scientific title
Study acronymCESAR
Study objectivesThe objective of this study is to test the hypotheses that, for patients with severe but potentially reversible respiratory failure, extracorporeal membrane oxygenation ECMO:
1. Will increase the rate of survival without severe disability by six months post randomisation.
2. Will be cost effective, compared to conventional ventilatory support.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedRespiratory tract diseases: Severe acute respiratory failure
InterventionConventional positive pressure ventilation vs. Extracorporeal Membrane Oxygenation (ECMO)
Intervention typeOther
Primary outcome measure(s)

Death or severe disability at six months. Severe disability will be defined as requiring full time nursing care at home, or continued residence in hospital.

Key secondary outcome measure(s)

1. Hospital Indices: duration of ventilation, length of ITU stay, length of hospital stay. Daily APACHE II score. In addition, data will be collected on ventilator settings, arterial blood gases, total intake minus output excluding blood loss and replacement, weight, full nutrition, haemoglobin, white blood cell count, blood products administered, prone position, nitric oxide, creatinine, bilirubin and maximum temperature. For ECMO patients only, data will be collected on mode (VV/VA), blood flow and sweep flow.
2. Follow up: Survivors will be contacted 6 months after randomisation for a detailed domicillary by a chest physician using a structured data collection form. Patients (or their carers, if necessary) will also complete questionnaires, assessment using standard scales to assess their activities of daily living, respiratory symptoms and psychological state.

Economic issues: The trial will assess the cost of treatment to the health and social services and to patients and their families in each treatment group. An incremental cost-effectiveness ratio will be calculated and compared to that for similar life-extending treatments. Information for the costs of inpatient and domicillary care will be collected using methods adapted from the neonatal ECMO Trial.
