RETRACTED: RECOVERIES OF POSTTETANIC TWITCH AND TRAIN-OF-4 RESPONSES AFTER ADMINISTRATION OF VECURONIUM WITH DIFFERENT INHALATION ANESTHETICS AND NEUROLEPTANESTHESIA (Retracted article. See vol. 122, pg. 150, 2019)

We have studied recovery of post-tetanic twitch (PTT) and train-of-four (TOF) responses after administration of vecuronium in 100 patients under different inhalation anaesthetics and neuroleptanaesthesia. Patients were allocated randomly to five groups of 20 patients each to receive: neuroleptanaesthesia (droperidol and fentanyl), halothane, isoflurane, enflurane or sevoflurane (1 MAC in nitrous oxide and oxygen). The times from initial administration of vecuronium 0.2 mg kg-1 to the first appearances of Tl, T2, T3 and T4 differed significantly between groups. However, the intervals to the first appearance of PTT1, PTT10 and PTT20 did not differ significantly between groups.
