Key result
Intravenous ephedrine bolus administration improved left ventricular contractility (EFA increased from 33% to 49%) without causing relevant changes in left ventricular afterload.

Ephedrine may support contractility under combined anesthesia; leaves open confirmation in randomized trials and outcome impact.
Does intravenous ephedrine bolus administration improve left ventricular function in patients without cardiovascular disease under high thoracic epidural anesthesia combined with general anesthesia?
Absolute Event Rate: 49% vs 33%
Intravenous ephedrine improves left ventricular contractility without significantly increasing afterload in patients under high thoracic epidural and general anesthesia.
Goertz et al. (1994) studied Patients without cardiovascular disease under high thoracic epidural anesthesia combined with general anesthesia. Intravenous ephedrine bolus vs. Baseline was evaluated on Area ejection fraction (EFA). Intravenous ephedrine bolus administration improved left ventricular contractility (EFA increased from 33% to 49%) without causing relevant changes in left ventricular afterload.
