Aim To investigate the effectiveness and safety of alfentanil in general anesthesia.Methods In this study, a multicenter randomized double-blind con¬trolled study was conducted.A total of 352 subjects were selected and randomly assigned to fentanyl group (group A, n =176) and alfentanil group (group 15, n = 176).Anesthesia induction: intravenous midazolam 0.03 mg • kg-1 + fentanyl 25 p.g • kg"'(group A) or alfentanil 4 p,g • kg-1 ( group 15) + propofol 2 mg • kg"1 + rocuronium 0.8 mg • kg"1.Sevoflurane + fent¬anyl ( group A ) or alfentanil ( group B ) + rocuronium were used for anesthesia.The vital signs of patients re¬covery time and extuhation time, anesthesia-related complications and the use of related remedial drugs during anesthesia induction and maintenance were compared between the two groups.Results During the induction and maintenance period of anesthesia, alfentanil and fentanyl could equally effectively inhibit the stress response induced by endotracheal intubation and surgical stimulation.Alfentanil also showed more effective inhibition on stress response induced by endo¬tracheal intubation and surgical stimulation than that of fentanyl ( P < 0.05 ) .However, there was no signifi¬cant difference in the incidence of intraoperative hypo¬tension and hypertension and the time of anesthesia re¬covery and extubation between the two groups.Conclu¬sions Both alfentanil and fentanyl can effectively in¬hibit the stress response induced by surgical stimulation and could be safely used in general anesthesia in sur¬gery.Alfentanil has more advantages in maintaining the stability of blood pressure and heart rate during an¬esthesia induction and maintenance.
