ARTHROPLASTY, REPLACEMENT; ANESTHESIA Clinical Trial
Official title:
Is Postspinal Hypotension a Sign of Impaired Cardiac Performance in the Elderly? An Observational Mechanistic Study
Patients, scheduled for elective arthroplasty were monitored with Lithium Dilution Cardiac Output monitor (LiDCOplus™) before and 45 minutes after spinal anesthesia. Hypotension was defined as systolic blood pressure ≤ 100 mmHg or ≥ 30% decrease from baseline. Associations between hypotension and the hemodynamic changes after preanaesthetic fluid loading and spinal anesthesia were analysed by logistic regression analyses.
