Feasibility of early reversal of vecuronium with neostigmine in patients with elective surgery / 中国临床药理学与治疗学

ABSTRACT

AIM: To investigate the feasibility of early reversal of vecuronium with neostigmine. METHODS: 48 patients (ASA class I or II) scheduled for elective surgery undergoing general anaethesia were randomly assigned to vecuronium group (n=16) and vecuronium+ neostigmine group (n=32). Furthermore, the latter was divided into two groups according to the time of reversal. In vecuronium+ neostigmine group 1, the patients received neostigmine antagonization within 10 min after vecuronium administration,and in vecuronium+neostigmine group 2, time of reversal within 11-30 min after vecuronium administration. All patients received vecuronium 1.5 mg?kg -1 after general anesthesia. Neostigmine 0.05 mg?kg -1 +atropine 0.5 - 1.0 mg+saline 8 ml was administered to vecuronium+ neostigmine group and recovery was compared with that of vecuronium patients who received 8 ml saline. The time from vecuronium administration to recovery of?TOF? 0.25 ?and? 0.7 ?was recorded.?RESULTS: In vecuronium group, the recovery time to TOF 0.25 and 0.7 was ( 45.58 ? 8.88 ) min, and ( 67.59 ? 5.60 ) min, respectirely; in vecuronium+ neostigmine group 1,it was ( 23.45 ? 2.82 ) min, and ( 31.86 ? 3.36 ) min, respectirely; and in vecuronium+neostigmine group 2, it was ( 28.70 ? 4.13 ) min,and ( 38.86 ? 2.10 ) min, respectirely. The recovery time in vecuronium+neostigmine group was evidently shorter than that in vecuronium group (P
