From the Research
Arterial pH Range in ESRD Patients on Maintenance Hemodialysis
- The normal range for arterial pH in patients with End-Stage Renal Disease (ESRD) on maintenance Hemodialysis (HD) is not explicitly stated in the provided studies.
- However, study 1 reports a mean pH of 7.41 ± 0.03 predialysis and 7.48 ± 0.05 postdialysis in 25 veterans with ESRD receiving outpatient hemodialysis.
- Study 2 categorizes predialysis pH as <7.30,7.30 to 7.34,7.35 to 7.39, or ≥7.40, and postdialysis pH as <7.40,7.40 to 7.44,7.45 to 7.49, or ≥7.50, but does not provide a specific normal range.
- Study 3 finds significant differences in pH before and after HD session, but does not provide a specific normal range.
- Study 4 discusses the importance of acid-base balance in dialysis patients, but does not provide a specific normal range for arterial pH.
Factors Affecting Arterial pH in ESRD Patients on Maintenance Hemodialysis
- Buffer bicarbonate concentration has a significant effect on bicarbonate concentration after dialysis 3.
- Predialysis acid-base parameters and post-HD pH are independent of buffer bicarbonate content 3.
- Serum calcium and albumin levels are associated with pulmonary hypertension severity, which may be related to acid-base balance 5.
- Predialysis pH ≥7.40 is associated with elevated risk of all-cause and cardiovascular mortality 2.
