Fentanyl, though generally regarded as a short‐acting narcotic analgesic, can give unexpected respiratory depression several hours after the last dose. This potentially very dangerous effect is explained in pharmacokinetic studies by a mobilisation of fentanyl from tissue stores. In this report we describe a patient who, following a Harrington correction for scoliosis done with neurolept analgesia, developed a severe respiratory depression 5 h after the last dose of fentanyl. 
Respiratory depression following administration of low dose buprenorphine as postoperative analgesic after fentanyl balanced anaesthesia
A clinical observation of respiratory depression following the administration of buprenorphine as postoperative analgesic after balanced anaesthesia with fentanyl is reported to emphasize the importance of the theoretical basis of anaesthesiology. Expand

It is confirmed that OIRD in the acute setting involves complex and interrelated factors and is a significant cause of preventable morbidity and mortality. Expand
Opioid analgesics and narcotic antagonists
Alfentanil is a potent short-acting opioid with a rapid onset and short duration of action, and it is, therefore, the ideal analgesic for focused and ambulatory interventions. Expand

The data indicate that fentanyl's popularity has occurred because it has minimal cardiovascular effects, does not result in increases in plasma histamine, is relatively short in onset of action and duration of effect, is easy and inexpensive to synthesize and prepare for the marketplace, and is now familiar to clinicians working in pain and perioperative medicine throughout the world.

Adverse Effects of Spinal Opioids in Acute Pain and Their Management
In conclusion, analgesia and respiratory depression are dual complimentary effects involving μ and δ-receptors and suggests that pharmacological tailoring by molecular engineering may lead to the development of a drug with selective affinity to analgesic receptors. Expand
Antagonism of fentanyl and alfentanil by intravenous plus subcutaneous naloxone
Twenty patients undergoing microlaryngoscopy were anaesthetised with thiopentone and half received fentanyl supplementation and the other half alfentanil and Respiratory depression in the alfenil group was less pronounced and of shorter duration than in the fentanyl group. Expand
Adverse Effects of General Anaesthetics
Adequate knowledge of drug pharmacology, experience with the use of drugs and proper perioperative assessment of patients are needed for the prevention of ADRs in anaesthesia. Expand
Fentanyl - A Potent Opioid Analgesic: A Review
It was reported that the 3rd position of a methyl group (-CH3) into the piperidine ring, increases analgesic potency, and it was found that activity of the cis (+) 3-methylfentanyl more potent than fentanyl, whereas the cis negative form was less potent. Expand

The distribution and redistribution of fentanyl & norfentanyl in post mortem samples.
The varied distribution of fentanyl in the body after death as a result of misadventure is highlighted and the importance of multi-site sample collection and subsequent analysis for a thorough post mortem toxicological investigation is demonstrated. Expand


Pharmacokinetics of fentanyl as a possible explanation for recurrence of respiratory depression.
It is confirmed that fentanyl is excreted in the gastric juice and reabsorbed from the alkaline medium of the small intestine and the stomach wall in rats has an important storage capacity for fentanyl. Expand
Biphasic Respiratory Depression after Fentanyl—Droperidol or Fentanyl Alone Used to Supplement Nitrous Oxide Anesthesia
Either fentanyl or Innovar was administered to supplement nitrous oxide anesthesia for operations on 29 patients, and full recovery appeared to be more rapid with Innovar than with fentanyl alone. Expand
Intravenous fentanyl kinetics
Fentanyl kinetics and excretion in 7 healthy male subjects who were given a 3.2‐ or 6.4‐μg/kg dose of 3H‐fentanyi intravenously and fluctuations in plasma levels may contribute to prolonged and recurrent ventilatory effects of fentanyl. Expand
Fentanyl Disposition in Cerebrospinal Fluid and Plasma and Its Relationship to Ventilatory Depression in the Dog
It is concluded that fentanyl, a highly lipophilic drug, equilibrated rapidly between plasma and CSF, and that there was a close correlation between the concentrations of fentanyl in plasma andCSF and the intensity of respiratory depression. Expand
Delayed respiratory depression after use of fentanyl during anaesthesia.
A positive correlation between resolution of the clinical features and the disappearance of B catarrhalis from the respiratory tract is observed, which seems to behave as an opportunistic pulmonary invader rather than a primary pathogen. Expand
Ventilatory Responses to Hypercapnia and Hypoxia at Normothermia and Moderate Hypothermia During Constant‐Depth Halothane Anesthesia
The data suggest that the anesthesiologist maintain even greater vigilance over his patient during hypothermia since the usual clinical clues are obscured should hypercapnia or hypoxia develop. Expand
