In our hospital,intravenous patient-controlled analgesia (IV-PCA) with fentanyl is used for the relief of postoperative pain.In this study,we investigated the dosages,correlation between fentanyl dose and operation time,and the relationship between the fentanyl dose and surgical site in patients who had used IV-PCA following operations on digestive organs.We also investigated adverse events due to fentanyl.Regardless of the degree of invasiveness and the surgical site,pain control could be achieved at fentanyl doses lower than those stated in the package insert.When adverse events appeared,a 30% reduction in the dose of fentanyly permitted its administration to be continued.Our findings suggested that IV-PCA with fentanyl is a useful strategy for postoperative pain control.
