    Abstract:
    PURPOSE: To study recovery from vecuronium-induced neuromuscular block in diabetic patients during total iv or sevoflurane anesthesia. METHODS: 30 diabetic patients were assigned to diabetes mellitus (DM)-total iv anesthesia (TIVA); (n = 15) or DM-sevoflurane (S) groups (n = 15). Thirty healthy patients were divided into control-TIVA (n = 15) or control-S groups (n = 15). In the DM-TIVA or control-TIVA groups and DM-S or control-S groups, anesthesia was maintained with propofol and fentanyl, and nitrous oxide-oxygen-sevoflurane 1.7%, respectively. After receiving vecuronium 0.1 mg.kg(-1)iv, recovery of the train-of-four (TOF) was compared among the four groups. RESULTS: Times to the return of T2, T3, or T4 in the DM-TIVA and DM-S groups were longer than in the control-TIVA and control-S groups (46.9 +/- 13.8 vs 32.2 +/- 10.7 and 32.6 +/- 8.7 min for T2, P < 0.05). T1/control in the DM-S group was less than in the control-TIVA and DM-TIVA groups 50 to 120 and 70 to 120 min after receiving vecuronium, respectively (P < 0.05). T1/control in the control-S group was less than in the control-TIVA group 80 to 120 min after receiving vecuronium (P < 0.05). TOF ratio in the DM-S group was less than in the control-TIVA, DM-TIVA, and control-S groups, 60 to 120, 80 to 120, and 80 to 120 min after receiving vecuronium, respectively (P < 0.05). CONCLUSION: In diabetic patients receiving vecuronium, recovery of T1/control and TOF ratio are delayed during sevoflurane anesthesia, but not in association with total iv anesthesia.
