Effect of Remimazolam on Induction and Maintenance of General Anesthesia in Kidney Transplant Patients

Purpose This study aims to evaluate the effect of remimazolam on induction and maintenance of general anesthesia in kidney transplant patients. Methods 120 patients undergoing kidney transplant were divided into two groups: Propofol group (Group P) and Remimazolam group (Group R). Anesthesia induction: remimazolam had injected IV at a dose of 0.15–0.35 mg/kg in Group R, while propofol had injected IV at a dose of 2.0–2.5 mg/kg in Group P. Anesthesia maintenance: remimazolam was injected IV at a dose of 0.3–1.0 mg·kg−1·h−1 and propofol was injected IV at a dose of 1–12 mg·kg−1·h−1 in Group R, propofol was injected IV at a dose of 3–12 mg·kg−1·h−1 in Group P. All patients have the same remaining anesthesia durgs. Results Compared with Group P, in Group R the time of disappearance of the eyelash reflex and the time to drop to 60 in BIS was longer (P < 0.05), the time of awakening was shorted (P < 0.05), the MAP of T6 was fluctuated less (P < 0.05), the incidence of hypotension and injection pain during induction was reduced (P < 0.001), the incidence of intraoperative bradycardia during operation was reduced (P < 0.05), the dosages of sedatives drug during maintenance was reduced (P < 0.05). There was no statistically significant difference in postoperative renal function between the two groups of patients (P > 0.05). Conclusion Remimazolam can be safely and effectively used for the induction and maintenance of general anesthesia in kidney transplant patients.
