Blood pressure monitoring gaps in patients with left ventricular assist devices presenting for non-cardiac surgeries
Authors' conclusion
Patients with a HM2 undergoing noncardiac surgery had nearly three-fold higher odds of blood pressure monitoring gaps of 10 min or greater compared to patients with a HM3.
Study context
- Population
- Patients with left ventricular assist devices (LVAD) undergoing noncardiac surgery without arterial lines at induction (noninvasive blood pressure (NIBP) monitoring), academic university hospital
- Participants
- 115 patients · 187 noncardiac surgeries
- Exposure
- HM3 vs HM2 LVAD
- Outcome
- Association of BP monitoring gaps (≥10 min) with LVAD type, multivariable logistic regression
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
- HM3 vs HM2: P = 0.02
Observational data: associations, not effects.
Further findings
Monitoring gaps by other factors
- Higher odds of monitoring gap with morbid obesity
- P = 0.04
- Higher odds of monitoring gap with surgical duration >180 min
- P = 0.001
Arterial line placement after induction (post-hoc analysis)
- Morbid obesity associated with increased odds
- P = 0.05
- GA associated with increased odds
- P = 0.007
- Prolonged surgery associated with increased odds
- P < 0.001
- Post-hoc analysis
