Detection of venous needle dislodgement during haemodialysis using fractional order shape index ratio and fuzzy colour relation analysis

Abstract

Venous needle dislodgement (VND) is a life-threatening complication during haemodialysis (HD) treatment. When VND occurs, it only takes a few minutes for blood loss in an adult patient. According to the ANNA (American Nephrology Nurses' Association) VND survey reports, VND is a concerning issue for the nephrology nurses/staff and patients. To ensure HD care and an effective treatment environment, this Letter proposes a combination of fractional order shape index ratio (SIR) and fuzzy colour relation analysis (CRA) to detect VND. If the venous needle drops out, clinical examinations show that both heart pulses and pressure wave variations have a low correlation at the venous anatomic site. Therefore, fractional order SIR is used to quantify the differences in transverse vibration pressures (TVPs) between the normal condition and meter reading. Linear regression shows that the fractional order SIR has a high correlation with the TVP variation. Fuzzy CRA is designed in a simple and visual message manner to identify the risk levels. A worst-case study demonstrated that the proposed model can be used for VND detection in clinical applications.

Needle dislodgement in hemodialysis patients: Progress in prevention and early intervention

“…This method can be optimized economically and is highly efficient if combined with an air‐free blood tubing system such as the GENIUS® dialysis machine (Fresenius Medical Care, Bad Homburg, Germany) 23,24 . Lin et al quantified transverse vibration pressures in different conditions to distinguish a venous needle dislodgement‐specific fractional order shape index ratio for accident detection 25 . Other patents, including US2015246173A1 and US10688237B2 mentioned above, provided a method of dislodgement detection based on arterial and venous pressures through the discrimination between a pressure drop resulting from venous needle dislodgment and from the regular no‐flow period of the HD machine 26,27…”

Novel wearable device for blood leakage detection during hemodialysis using an array sensing patch

“…It carries a serious implication and several literatures on medical risk management elucidate VND as a potentially serious complication in HD. If the blood pump is not stopped immediately, the patient could bleed to death within minutes [3]. As Ribitsch et al [4] reported in their study, the American Nephrology Nurses' Association (ANNA) carried out an investigation on VND and its consequences, and results showed that 77% of nurses had seen at least one incidence of VND in the past five years.…”

Integration of wireless flexible sensor and virtual internal impedance model for blood leakage detection during haemodialysis

“…Dialysis machines have been improved to prevent air in the blood circuits, blood clotting, dialyser reaction, roller pump failure, and blood leakages [3,4]. Various alarms have been incorporated into a dialysis machine with a pressure sensor, an optical sensor, a bubble sensor, flowmeter, and temperature sensor to monitor the dialysis conditions.…”
