Prognostic Value of Finger Blood Pressure in Arteriovenous Fistula Care

The goal of this trial is to investigate the prognostic value of monitoring finger blood pressures (FBPs) in predicting the success of surgically created arteriovenous fistula (AVF) for patients with end stage renal disease. The main questions it aims to answer is:

- Can FBPs predict AVF maturation?

Participants will undergo FBP measurements at pre-op, immediately post-op, 4 weeks and 6 weeks post-AVF creation.

Inclusion criteria

Participants has documented Chronic Kidney Disease (CKD), determined by Glomerular Filtration Rate (GFR)
Participant is recommended for renal replacement therapy based on clinical assessment of renal function as well as CKD staging, as documented in clinical notes.
Haemodialysis was chosen as the most appropriate renal replacement therapy
Participant is able to consent to the creation of an AVF in preparation for hemodialysis.
Participant is able to adhere to follow-up assessments of AVF maturation, if applicable.

Treatment and study plan

Finger Blood Pressure Measurement

Other

Finger Blood Pressure Measurement were taken from three digits: the thumb (F1), the middle finger (F2), and the little finger (F3) from both arms.

Primary outcomes

Correlation between AVF maturation and changes in Finger Blood Pressure measurements at baseline and immediately post-op

Time frame: Within 24 hours

To determine whether if there are any pattern in changes observed in FBP pre and post-creation that can be used for correlation to AVF maturation.

Secondary outcomes

Correlation between AVF maturation and changes in Finger Blood Pressure measurements across other timepoints

Time frame: Until 6 weeks post-operation

To determine whether changes in FBP across time points (pre-op, post-op, 4 weeks and 6 weeks post-op) is correlated with AVF maturation
