Fentanyl citrate is a synthetic narcotic 1,000 times as potent as meperidine. It produces minimal hemodynamic effects and is characterized by a rapid onset of sedation and analgesia, a relatively short duration of action (approximately 30 to 40 minutes), and rapid reversal with opiate antagonists. These properties make fentanyl an ideal drug for emergency department use. The safety of fentanyl use in an adult ED population has not previously been studied. We retrospectively reviewed the charts of 841 patients who received fentanyl at the University of Cincinnati Center for Emergency Care between January 1985 and June 1988. The study population included 497 (59%) men and 344 (41%) women, with an average age of 33 years. The average dose of fentanyl was 180 micrograms (range, 25 to 1,400 micrograms). Six patients (1%) experienced mild side effects including nausea (one), emesis (two), urticaria (one), and pruritus (two). Nine patients (1%) developed more serious complications including six cases (0.7%) of respiratory depression and three cases (0.4%) of hypotension. Two of 183 patients (1%) who received midazolam and two of nine patients (22%) who received haloperidol developed respiratory depression. Four of the six patients with respiratory depression and two of the three patients with hypotension were intoxicated. All of the complications were transient, and none resulted in hospitalization. We conclude that fentanyl is a safe drug for use in the ED. To maximize safety, we recommend careful dosing and titration, close patient monitoring, and the availability of naloxone hydrochloride and resuscitation equipment.(ABSTRACT TRUNCATED AT 250 WORDS)

Fentanyl citrate or morphine chlorhydrate are injected intramuscularly at increasing doses to patients suffering from intense pain in the facial or trigeminal nerves territory: --fentanyl = 0.0015, 0.003, 0.006 mg/kg; --morphine = 0.100, 0.150, 0.200 mg/kg. The clinically observed side-effects are noted at regular time during the three hours following the injection. Fentanyl induces a drop in ventilation similar in duration to that of morphine, but it is more intense. Fentanyl induces less vomiting, but more euphoria than morphine and the sedation is the same in frequency and intensity with both drugs. The only difference of clinical importance concerns the cardio-vascular effects: morphine induces a constant, dose-related hypotension as that of fentanyl, at equianalgesic doses, is negligible.

Akathisia is a condition wherein sitting calmly and quietly is impossible, with a representative complaint of restless legs. It is generally assumed to be caused by anti-dopamine activity. In severe cases, it has been known to result in suicide attempt. We reported a case of drug-induced akathisia with difficulty in oral intake, in which fentanyl citrate sublingual tablets were found to be effective in relieving symptoms. The patient was a female aged 50's who had a gastric cancer with peritoneal dissemination causing pain and vomiting. Palliative care was requested for management of symptoms. Metoclopramide and haloperidol were administered for vomiting. However, because of the complaints of restless legs, the case was diagnosed as drug-induced akathisia. Fentanyl citrate sublingual tablets were then administered for pain management, resulting in temporary improvement of akathisia symptoms.
