Sensory Examination and Pharmacological Modulation of Oral Hyperexcitability in Patients With Atypical Odontalgia and Matched Healthy Controls
This project examines experimental pain and chronic pain in the mouth, specifically the condition called atypical odontalgia (AO:atypical toothpain). In 16 patients with AO and 16 healthy persons, capsaicin (chili-pepper) is applied to the gingiva to cause pain. This pain is evaluated by the participants. In three sessions, 3 different medications are tested for effect on the pain. The medications are fentanyl, S-ketamine and placebo-treatment (saline). The aim is to know more about pain mechanisms in AO in order to develop an effective treatment.

There are multiple retrospective studies detailing the use of etomidate in pediatric procedural sedation but few to no prospective clinical trials. None have compared etomidate to ketamin...
Providing adequate sedation and analgesia is an integral part of the practice of colonoscopy procedure. There are various protocols and methods used to prevent discomfort and alleviate pa...
Comparing patients receiving subanesthetic doses of Ketamine vs placebo to see if it can reduce narcotic needs for patients receiving a tonsillectomy and adenoidectomy
This protocol hopes to determine whether the use of dexmedetomidine-ketamine can reduce the use of standard of care fentanyl-midazolam sedation during bronchoscopy. This may result in less...
The Phase I clinical trial in approximately 50 healthy volunteers will be conducted at a single clinical center in two stages. Stage 1 is an open-label, cross-over comparison of a single d...
Fentanyl is a potent synthetic opioid. Abuse of fentanyl patches is rarely occurring, but has been described. In this case a patient had been drinking hot tea mixed with two fentanyl patches. He was f...
Abstract 1. Fentanyl is a highly lipophilic opioid commonly used to treat cancer pain. Plasma protein binding (PPB) of fentanyl in human plasma is reported as 80-85%, however it is unclear whether ...
Ketamine is used as a general anesthetic for short-term surgical procedures. The aim of this study is to compare the effect of intravenous (IV) ketamine and intramuscular (IM) ketamine in children adm...
Postoperative pain is one of the most important complications encountered after surgery. A number of options are available for treating pain following surgery. One of those options is the use of intra...
Ketamine is traditionally avoided in sedation management of patients with risk of intracranial hypertension. However, results from many clinical trials contradict this concern. We critically analyzed ...
Medical and Biotech [MESH] Definitions
A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.
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)
A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.
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 short-acting opioid anesthetic and analgesic derivative of FENTANYL. It produces an early peak analgesic effect and fast recovery of consciousness. Alfentanil is effective as an anesthetic during surgery, for supplementation of analgesia during surgical procedures, and as an analgesic for critically ill patients.
