# Intradialytic Hypertension: A Pattern Worth Investigating

Reassess after changes and measure the broader pressure burden. Success is not simply forcing one intradialytic number lower.

## A rise during treatment

Blood pressure can increase during dialysis despite fluid removal. Volume, vascular resistance, sodium balance, medications, and measurement conditions may contribute.

## Confirm recurrent treatment-related rise

Compare technically reliable pre-, intra-, and postdialysis pressures across sessions and record symptoms. A repeated rise into a hypertensive range deserves evaluation; an isolated painful or anxious reading is weaker evidence. Check home or ambulatory BP to determine the interdialytic burden.

## Assess the interval too

Home or ambulatory pressures, weight gains, dry-weight assessment, and sodium exposure help interpret the pattern.

## Review three modifiable contributors

Reassess target weight and congestion, whether dialysate sodium promotes a positive sodium balance, and whether medication timing or dialyzability reduces coverage. Make one reasoned change with follow-up when feasible. A postdialysis rise does not prove the patient needs more fluid or immediate indiscriminate medication.

## Avoid the stability trap

A high chair-side pressure does not prove adequate perfusion or justify aggressive changes without context. Symptoms and organ status remain central.

## Treat the mechanism

Reassess after changes and measure the broader pressure burden. Success is not simply forcing one intradialytic number lower.
