Key result
Preoperative hypertension (OR 1.785), older age, and shorter sleep duration the day before surgery were identified as independent risk factors for preoperative blood pressure fluctuations >20%.
Why the study?
The study was conducted to analyze factors affecting preoperative blood pressure fluctuations in patients undergoing elective surgery.
Population
776 elective surgical patients
Comparison
Elevated BP group (n=328) vs non-fluctuating group (n=448)
Design
Observational cohort study

Preoperative BP fluctuations may link to identifiable factors in elective surgery; leaves open causal roles and need for prospective validation.
Observational (n=776)
No
Odds Ratio: 1.785 (95% CI 1.142–2.807)
p-value: p=0.0114
Preoperative blood pressure increases significantly upon operating room entry, with older age, preoperative hypertension, and shorter sleep duration acting as independent risk factors for fluctuations >20%.
Cheng et al. (2023) conducted an observational in Preoperative blood pressure fluctuation (n=776). Preoperative hypertension vs. No preoperative hypertension was evaluated on Preoperative blood pressure fluctuation >20% (OR 1.785, 95% CI 1.142-2.807, p=0.0114). Preoperative hypertension (OR 1.785), older age, and shorter sleep duration the day before surgery were identified as independent risk factors for preoperative blood pressure fluctuations >20%.
