Sufentanil reduces emergence agitation in children receiving sevoflurane anesthesia for adenotonsillectomy compared with fentanyl.

Background: Emergence agitation is a common problem in pediatric anesthesia, especially after sevoflurane induction and maintenance anesthesia. The purpose of this study was to investigate the effect of sufentanil to reduce emergence agitation after sevoflurane anesthesia in children undergoing adenotonsillectomy compared with fentanyl.

Methods: One hundred and five children, aged 3 - 11 years, were randomly allocated to receive normal saline (control group), sufentanil 0.

[Cohort study of remifentanil-induced hyperalgesia in postoperative patients].

Objective: To investigate the incidence of remifentanil-induced hyperalgesia and screen for the relevant influencing factors in the post-operative patients.

Methods: A total of 1620 patients from June 2008 to December 2008 in our hospital undergoing general anesthesia with remifentanil and whose length of operative incision was less than 4 cm were enrolled. The incidence of postoperative hyperalgesia was investigated and recorded at the timepoints of staying at post-anesthesia care unit (PACU), 4 h and 24 h postoperation respectively.

[Effect of the new propofol target controlled infusion system in children undergoing high ligation of hernial sac].

Objective: To discuss the effect of the new target controlled infusion (TCI) system in Chinese children undergoing minor operation and compared with TCI system with Marsh parameters.

Methods: Ninety ASA I, aged 3 - 5 yrs children undergoing elective unilateral high ligation of hernial sac under general anesthesia were randomly divided into group L (n = 45) and group M (n = 45) 2 groups. All subjects were unpremedicated.
