Intra-dialytic hypertension (IDHtn) is a haemodynamic complication of
maintenance haemodialysis that may worsen cardiovascular outcomes. We examined the
relationship between extracorporeal blood flow rate (QB) and IDHtn. We evaluated the roles
of ultrafiltration goal, dialyser surface area, vascular access type and dialysis duration in a
single-centre cohort in Southeastern Nigeria
We performed a retrospective analysis of 2,491 haemodialysis sessions. Patientand session-level characteristics were described, and generalised estimating equations (GEE)
were used to model predictors of IDHtn while accounting for repeated sessions per patient.
Outcomes included the occurrence of IDHtn (hour-specific and overall), as well as hourly
changes in systolic blood pressure (SBP) and mean arterial pressure (MAP). Key predictors
tested were average QB, hourly QB change, ultrafiltration (UF) goal, dialyser surface area,
vascular access type and treatment duration.
IDHtn occurred in 63.4% of sessions. The most frequent hour for ≥10 mmHg SBP
rises was Hour 2 (37.1%). Average QB was 285.62±42.17. Higher average QB was
independently associated with lower odds of IDHtn (B = −0.009; Exp[B] = 0.991; 95% CI:
0.988–0.994; p < 0.05), indicating a modest protective effect per 1 mL/min increment. In
contrast, acute increases in QB during Hours 2 and 3 were associated with greater odds of
IDHtn (B = 0.012 for both; Exp[B] = 1.012; p < 0.05). Dialyser surface area was a strong
predictor of first-hour IDHtn (B = 2.076; p < 0.05; Exp[B] = 7.98). Dialysis duration showed
a complex, time-dependent relationship: longer prescribed session length was protective for
overall IDHtn (B = −0.343; Exp[B] = 0.709; 95% CI: −0.474 to −0.213; p < 0.05), yet was
associated with higher odds of IDHtn in Hour 3 (B = 0.599; Exp[B] = 1.82; p < 0.05) and
Hour 4 (B = 1.114; Exp[B] = 3.05; p < 0.05). UF goal trended toward increasing IDHtn but did not reach significance (p < 0.05). Vascular access type did not independently predict
IDHtn in adjusted models.
IDHtn was common. Stable, adequately high average QB modestly protected
against IDHtn, while abrupt mid-session increases raised risk. Larger dialyser membranes are
predisposed to early BP rises. Though longer sessions were protective overall, prolonged
treatment increased mid- and late-session risk. Strategies include maintaining steady QB,
avoiding abrupt increases, using moderate dialyser sizes for susceptible patients, and
individualising session length and UF rate with close late-session monitoring.
