This is a prospective observational pilot study of patients under the care of the Royal Free Hospital with chronic kidney disease who have been established on regular thrice weekly haemodialysis treatments in a dialysis centre,to measure the changes in blood flow in the ear during haemodialysis.
10 patients, attending for thrice weekly outpatient haemodiafiltration shall be studied during a dialysis session using a CE marked commercially available digital otoscope capable of recording digital videos of the tympanic membrane and ear canal. Patients will receive standard clinical care and monitoring of their dialysis session, which includes recording of blood pressure and changes in haematocrit and volume status during dialysis and noting patient symptoms.
