title: [Influence of intraoperative fentanyl and remifentanil infusion on early postoperative oral intake after general anesthesia].
abstract: BACKGROUND
  There is no reports on influence of intraoperative fentanyl and remifentanil infusion on ability of oral intake after short stay surgery under general anesthesia.
  
  
  METHODS
  Data were collected retrospectively on 497 patients undergoing short stay surgery under general anesthesia with intraoperative remifentanil infusion (R group, n = 273) or without intraoperative remifentanil infusion (NR group, n = 224). The amount of fentanyl used and percentage of patients unable to eat supper were compared.
  
  
  RESULTS
  Amount of fentanyl used in patients unable to eat supper were significantly higher than in patients able to eat supper in both NR and R groups. There is no difference in the percentage of patients unable to take supper between group NR and R. Total amount of fentanyl used was significantly lower in group R than in group NR.
  
  
  CONCLUSIONS
  With or without the use of remifentanil, greater the amount of fentanyl used, greater the percentage of patients unable to eat. Amount of fentanyl used in R group was significantly less than in group NR; however the difference in percentage of patients unable to eat supper was not observed.
