<![CDATA[Intradialytic blood pressure variability (IDBPV) is a common hemodynamic phenomenon during hemodialysis. However, evidence describing sequential blood pressure changes throughout a hemodialysis session remains limited. This study aimed to describe temporal changes in intradialytic blood pressure among patients undergoing maintenance hemodialysis. Methods: A descriptive analytical study with a repeated-measures approach was conducted among 65 patients receiving maintenance hemodialysis at RSUD Indramayu, Indonesia. Participants were recruited using consecutive sampling. Systolic and diastolic blood pressure were measured hourly from the 1st to the 5th hour of a single hemodialysis session. Data were analyzed using descriptive statistics, paired t-tests, or Wilcoxon signed-rank tests. Results: Systolic blood pressure decreased initially, increased during the middle phase, and declined again toward the end of hemodialysis. Diastolic blood pressure showed a similar pattern, although the final decrease was not statistically significant. Significant differences were observed across all consecutive systolic blood pressure measurements (p < 0.05). Diastolic blood pressure changed significantly from Hours 1–2, 2–3, and 3–4 (p < 0.05), but not from Hours 4–5 (p = 0.060). Conclusion: Blood pressure fluctuated throughout the hemodialysis session, demonstrating dynamic intradialytic hemodynamic changes. These findings support routine intradialytic blood pressure monitoring to better characterize temporal blood pressure patterns during hemodialysis.]]>
