简要总结
The goal of this observational study is to learn about how screening tests inform the radial artery (RA) suitability for harvesting and coronary bypass grafting in adults with ischaemic heart disease. The main question it aims to answer is:
• What factors influence the diagnostic accuracy of RA screening in patients undergoing surgical coronary revascularisation?
Participants will:
- Receive an assessment of their RA through routinely used techniques (Modified Allen Test +/- pulse-oximetry, Barbeau Test and Ultrasound examination)
- Answer a symptoms scale about their physical experience after surgery
详细描述
A multi-centre cross-sectional study design to investigate the validity of radial artery (RA) assessment techniques in adults with ischaemic heart disease undergoing surgical coronary revascularisation with their RA being selected as an autologous graft conduit.
Patients taking part in the study will receive an assessment of the arterial forearm circulation from their non-dominant upper extremity through multiple observations.
Pre-operative observations. Before surgery (in the ward environment after the patient is being admitted or whilst patient in the anaesthetic room) the forearm blood circulation is measured through a Modified Allen Test (MAT) (+/- pulse-oximetry), Barbeau Test and Ultrasonography examination. Assessment will be performed by experienced Surgical Care Practitioners/Advanced Nurse Practitioners/Cardiac Specialist Registrars. These assessments will inform the decision to surgically expose the RA.
Intra-operative observations. Oxygen saturation readings are taken prior to harvest the RA. Once the RA is surgically harvested a series of measures are taken through a validated structured questionnaire: the Radial Artery Quality Evaluation Survey (RAQES).
Observations at 4-6 weeks post operation. Patients finger movements, cold tolerance sensitivity and tactile/touch perception is measured through an ordinal symptoms scale (Follow-up Radial Artery Harvesting Scale) at post-operative day 2-5 and at follow-up appointment (3-6 weeks after surgery). Bilateral comparison between hands and forearms will be undertaken. A Surgical Care Practitioner will perform this assessment post-operatively.
