The current study aimed to compare the effects between remimazolam and propofol on hemodynamic stability during the induction of general anesthesia in elderly *** used propofol at a rate of 60 mg/(kg·h)in the propofol group(group P)or remimazolam at a rate of 6 mg/(kg·h)in the remimazolam group(group R)for the induction.A processed electroencephalogram was used to determine whether the induction was successful and when to stop the infusion of the study *** measured when patients entered the operating room(T_(0)),when the induction was successful(T_(1)),and when before(T_(2))and 5 min after successful endotracheal intubation(T_(3)).We found that mean arterial pressure(MAP)was lower at T_(1–3),compared with T_(0) in both groups,but higher at T_(2) in the group R,whileΔMAP_(T0–T2) andΔMAP_(max) were smaller in the group R(ΔMAP_(T0–T2):the difference between MAP at time point T_(0) and T_(2),ΔMAP_(max):the difference between MAP at time point T_(0) and the lowest value from T_(0) to T_(3)).Cardiac index and stroke volume index did not differ between groups,whereas systemic vascular resistance index was higher at T_(1–3) in the group *** findings show that remimazolam,compared with propofol,better maintains hemodynamic stability during the induction,which may be attributed to its ability to better maintain systemic vascular resistance levels.

Traumatic brain injury(TBI)is an acquired injury of the brain caused by the impact of external forces on the brain(Maas et al.,2008).It is a major cause of death and disability among people of all ages(Maas et al.,2008).The primary mechanical injury to the brain initiates a cascade of secondary biochemical events that lead to acute and chronic neurodegeneration and activation of inflammatory pathways(Maas et al.,2008).Both brain-resident microglia and blood-derived myeloid cells-macrophages and monocytes that infiltrate the brain due to injury-induced blood-brain barrier damage,contribute to the inflammatory responses after TBI(Morganti et al.,2015).
