Remimazolam is safe and effective for inducing general anesthesia in patients with septic shock. Low, medium, and high doses of remimazolam can maintain a stable hemodynamic state, and the recovery of hepatic and renal function is certain to depend on the dose.

During remimazolam induction, the number of patients with intraoperative need for rescue remimazolam in the medium-dose and high-dose groups was significantly lower than in the low-dose group (p < 0.05). In terms of hemodynamic indexes, MAP in the high-dose group at T2 was lower than that at T0 (p < 0.05), and MAP at T2 was significantly lower in the high-dose group than that in the medium-dose group (p < 0.05). Furthermore, MAP at T4 in the medium-dose and high-dose groups declined compared with the low-dose group (p < 0.05). There were no significant differences in HR, CI, and SVI at different time points among the three groups (p > 0.05), but levels of HR and SVI decreased and CI increased after anesthesia compared with those before operation.
