Abstract
Background
Rebleeding is a frequent complication of peptic ulcer bleeding (PUB) and is associated with increased mortality. Blood pressure and heart rate are two easy non-invasive measurements to evaluate the hemodynamics and therefore a standard observation during hospitalization.
Objective
We aimed to investigate the dynamics of systolic blood pressure and heart rate up to time of peptic ulcer rebleeding.
Design
Retrospective matched cohort study. Hemodynamics in patients with peptic ulcer rebleeding was compared to hemodynamics in a matched control group consisting of patients with PUB without rebleeding. Blood pressure and heart rate in the six hours up to diagnosis of rebleeding was compared with baseline in the case cohort as well as with the matched control group.
Results
Thirty-eight patients with peptic ulcer rebleeding and 66 controls were included. Mean age was 75 years, 62% were males and 30-day mortality was 23%. Baseline systolic blood pressure in cases was 114 mmHg. Compared to baseline, we found significant decrease in systolic blood pressure two hours before rebleeding (4 mmHg; p = 0.041) and one hour before rebleeding (14 mmHg; p = 0.0002). Mean systolic blood pressure 30 min before rebleeding was 89 mmHg. No significant change was found in heart rate (p = 0.99). In the control group no change was found in systolic blood pressure or heart rate.
Conclusion
In patients with peptic ulcer rebleeding, hypotension develops 1–2 h before other symptoms of rebleeding. Thus, close monitoring of blood pressure is needed in order to ensure early identification of rebleeding in high-risk patients.
