Summary: | Objective: To observe the incidence of residual neuromuscular blockade at the end of
operation and during tracheal extubation, and analyze the risk factors causing residual
neuromuscular blockade by judging the degree of muscle relaxation according to clinical
signs when after using rocuronium or cis-atracurium in general anesthesia. Methods: 500
adults were implemented with propofol-remifentanil intravenous anesthesia or sevoflurane
inhalation anesthesia. Rocuronium and cis-atracurium were given, respectively. The TOFr was
observed with blind method by TOF Watch SX monitor during anesthesia. Results: The mean
TOFr=0.53±0.38 at the end of operation,including 275 cases of 0<TOFr<0.9 and 112 cases
of TOFr=0. The mean TOFr=0.97±0.12 at extubation, including 60 cases of TOFr<0.9. The
incidence of residual neuromuscular blockade at extubation showed an increasing trend with
the increase of age or body mass index. The average TOFr value at extubation, which interval
time over 10 min after neostigmine administration to extubation was significant higher than
that of interval time less than 10 min. Conclusions: There has 12% patients with TOFr<0.9
when extubation by estimating rocuronium and cis-atracurium effect with clinical signs and
experience, it has a hidden danger of residual neuromuscular blockade. The main risk factors
to increasing the incidence of residual neuromuscular blockade are growing old and the short
time of administrating muscle relaxants or neostigmine to extubation. |
