Key result
Each additional minute of intraoperative systolic arterial pressure below 80% of pre-induction baseline was associated with increased odds of progressing to a higher Clavien-Dindo complication classification (OR 1.020).
Why the study?
Intraoperative hypotension during hip fracture surgery is linked to 30-day mortality, but data correlating it with postoperative morbidity were lacking.
Is the duration and severity of intraoperative hypotension during hip fracture surgery associated with increased postoperative morbidity?
Population
52 patients undergoing hip fracture surgery
Comparison
Duration and severity of intraoperative hypotension across predefined blood pressure thresholds
Design

Intraoperative hypotension duration was associated with greater morbidity after hip fracture surgery; leaves open whether blood pressure targets improve outcomes in trials.

Odds Ratio: 1.02 (95% CI 1.008–1.035)
p-value: p=0.003
Cumulative duration of intraoperative hypotension (SAP < 80% of pre-induction baseline) during hip fracture surgery is significantly associated with increased postoperative morbidity.
Beecham et al. (2020) conducted a cohort in Hip fracture (n=52). Cumulative duration of intraoperative hypotension (SAP < 80% pre-induction baseline) vs. Shorter duration of hypotension was evaluated on Progression to a higher Clavien-Dindo complication classification (OR 1.020, 95% CI 1.008-1.035, p=0.003). Each additional minute of intraoperative systolic arterial pressure below 80% of pre-induction baseline was associated with increased odds of progressing to a higher Clavien-Dindo complication classification (OR 1.020).
