[The relationship between the intraoperative hypothermia and the residual neuromuscular of single intubation dose of vecuronium].

Objective: To study the relationship between the intraoperative hypothermia and the residual neuromuscular of single intubation dose of vecuronium.
Methods: The designed patients were from July to December in 2009. There are 36 male and 44 female cases. Their age was 19 to 59 years. The induction and sustaining are routine method. There were no additional muscle relaxant. Intraoperative nasopharyngeal temperature (T) < 36°C for the intraoperative hypothermia (LBT group) or non-intraoperative hypothermia group (NBT group). The patients turn back the PACU with tracheal intubation. Measured TOFr immediately after extubation.
Results: The incidence of residual neuromuscular single intubation dose of vecuronium was 28.7%. The incidence of postoperative residual neuromuscular was 43.2% (16/37) in the LBT group. The incidence of postoperative residual neuromuscular was 16.3% (7/43) in the NBT group. LBT group compared with the NBT group the incidence of postoperative residual neuromuscular was significant differences (P < 0.05).
Conclusion: The incidence of residual neuromuscular increases. When patients in the surgery exist low body temperature.
