====== Fentanyl ====== see [[Fentanyl Patch]]. Fentanyl (0.8 mg/kg) is intravenously administered immediately before surgery, followed by additional doses as needed. ---- Using [[fentanyl]] after surgical [[clipping]] for [[ruptured intracranial aneurysm]]s might decrease [[headache]] and produce few adverse effects. Adequate headache control showed improved dietary intake after [[subarachnoid hemorrhage]] ((Terakado T, Nakai Y, Ikeda G, Uemura K, Matsumaru Y, Ishikawa E, Matsumura A.
