Key result
Adrenaline infusion increases acute hemodynamics and leads to delayed diastolic blood pressure elevation vs dextrose.
Why the study?
The effects of 6-hour adrenaline infusion on presynaptic β-adrenoceptor stimulation and related hemodynamic and biochemical changes were investigated.
Does a 6-hour adrenaline infusion alter blood pressure, heart rate, and catecholamine levels in normal subjects?
Does a 6-hour adrenaline infusion alter blood pressure, heart rate, and catecholamine levels in normal subjects?
A 6-hour adrenaline infusion produces prolonged hemodynamic and sympathetic effects up to 24 hours later, consistent with enhanced presynaptic noradrenergic transmission.

May prompt caution for delayed BP effects after adrenaline exposure; leaves open relevance in cardiovascular patients.
Bachmann et al. (1992) studied Healthy volunteers (n=9). Adrenaline infusion vs. Dextrose infusion was evaluated on Blood pressure, heart rate, and catecholamine levels. A 6-hour adrenaline infusion significantly increased systolic blood pressure and heart rate during infusion, and elevated diastolic blood pressure 24 hours post-infusion compared with dextrose.
