Effects of fentanyl infusion on tracheal intubation and emergence agitation in preschool children anaesthetized with sevoflurane.
Summary of "Effects of fentanyl infusion on tracheal intubation and emergence agitation in preschool children anaesthetized with sevoflurane."
/st> Sevoflurane can be used as a sole agent for intubation in children, but studies have suggested that it is associated with emergence agitation. Fentanyl infusions can be used both to facilitate intubation and decrease emergence agitation. We investigated the effects of fentanyl on conditions at intubation and on emergence from sevoflurane anaesthesia without confounding nitrous oxide or premedication.
/st> IRB approval and informed consent were obtained. Subjects comprised 150 ASA physical status I or II (age, 2-6 yr). Anaesthesia was induced with sevoflurane in oxygen and maintained using a predetermined concentration of sevoflurane. Subjects were randomly allocated to receive one of three doses of fentanyl: vehicle only (control group), a bolus dose of 1 microg kg(-1) followed by a continuous infusion of 0.5 microg kg(-1) h(-1) (F1 group), or a bolus dose of 2 microg kg(-1) followed by a continuous infusion of 1 microg kg(-1) h(-1) (F2 group). Sevoflurane minimum alveolar concentration for tracheal intubation (MAC(TI)) and emergence agitation score were assessed.
/st> MAC(TI) values were 2.49%, 1.61%, and 1.16% in control, F1, and F2 groups, respectively (P<0.05). Agitation scores were 11.5, 7.0, and 2.6 in control, F1, and F2 groups, respectively (P<0.05).
/st> Fentanyl infusion consisting of a bolus dose of 2 microg kg(-1) followed by a continuous infusion of 1 microg kg(-1) h(-1) facilitates tracheal intubation and smooth emergence in children anaesthetized using sevoflurane. Clinical trial registration: this study was started in 2000 and was finished in 2008. We had no registration number. IRB approval was obtained.

Medical and Biotech [MESH] Definitions
A butyrophenone with general properties similar to those of HALOPERIDOL. It is used in conjunction with an opioid analgesic such as FENTANYL to maintain the patient in a calm state of neuroleptanalgesia with indifference to surroundings but still able to cooperate with the surgeon. It is also used as a premedicant, as an antiemetic, and for the control of agitation in acute psychoses. (From Martindale, The Extra Pharmacopoeia, 29th ed, p593)
A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)
Home Infusion Therapy
Use of any infusion therapy on an ambulatory, outpatient, or other non-institutionalized basis.
Central Nervous System Stimulants
A loosely defined group of drugs that tend to increase behavioral alertness, agitation, or excitation. They work by a variety of mechanisms, but usually not by direct excitation of neurons. The many drugs that have such actions as side effects to their main therapeutic use are not included here.
Virulence Factors, Bordetella
A set of BACTERIAL ADHESINS and TOXINS, BIOLOGICAL produced by BORDETELLA organisms that determine the pathogenesis of BORDETELLA INFECTIONS, such as WHOOPING COUGH. They include filamentous hemagglutinin; FIMBRIAE PROTEINS; pertactin; PERTUSSIS TOXIN; ADENYLATE CYCLASE TOXIN; dermonecrotic toxin; tracheal cytotoxin; Bordetella LIPOPOLYSACCHARIDES; and tracheal colonization factor.
The objective of this study was to examine the effects of low-dose infusion of landiolol on hemodynamics during tracheal intubation in elderly patients with cardiovascular disease. The study populatio...
Background: Dexmedetomidine, a specific alpha(2) agonist, has an analgesic-sparing effect and reduces emergence agitation. We compared an intraoperative dexmedetomidine infusion with bolus fentanyl to...
BACKGROUND: Macintosh laryngoscopic intubation is a lifesaving procedure, but a difficult skill to learn. The Airtraq optical laryngoscope (AOL) is a novel intubation device with advantages over the d...
PURPOSE: We investigated the effect of low-dose droperidol on heart rate-corrected QT (QTc) interval and interaction with propofol. METHODS: Seventy-two patients undergoing upper limb surgery were inc...
Obstructive fibrinous tracheal pseudomembrane is a rare, but potentially fatal complication associated with endotracheal intubation. It has been known that the formation of tracheal pseudomembrane is...
Various supraglottic airways may be used as a dedicated airway for insertion of intubating fibrescope and tracheal intubation in the patients with difficult to manage airways (Difficult Ai...
60 patients, in three group of 20 patients each, scheduled for surgery needing general anesthesia will be researched. Group A: tracheal intubation of single lumen tube using laryngoscope....
The purpose of this study is to determine whether depth of anesthesia has an effect on emergence agitation (EA) in children age 2 - 8 years old. EA is a common problem in pediatric patient...
The purpose of the study is to see if a small dose of propofol given intravenously (through a needle into a vein) at the end of anesthesia can make it less likely that children will be agi...
Purpose: This study is designed to assess the impact of teaching tracheal intubation using video-guided feedback on the ability to perform and maintain this clinical skill by medical stud...
