Filter by:Recent studies have investigated the use of local anesthetics (i.e. lidocaine, mepivacaine) to lessen the pain experienced with minor gynecologic procedures such as endometrial biopsy and office hysteroscopy. Local anesthetic injected into the uterine cavity has been demonstrated effective in some studies at decreasing patient pain associated with these intrauterine procedures at an anesthetic concentration of at least 2%. Based on this evidence, we hypothesized that an intrauterine lidocaine infusion may reduce patient pain during first trimester abortions.
This study will evaluate the effectiveness of a stepped care approach in treating depression and reducing pain.
This study will evaluate how genetic makeup contributes to the variation in people regarding their sensitivity to and experience of pain. Scientists believe that differences in information found in genes may explain why an analgesic drug, that is, one that treats pain, works effectively for some people but not for others. The study will explore pain that is acute (fast and short period). Knowledge gained from this ongoing study may permit development of an individualized analgesic drug prescription. Patients ages 16 to 35 who are in good health and have been referred for removal of impacted wisdom teeth; who are not allergic to aspirin or other nonsteroidal anti-inflammatory drugs (known as NSAIDs), sulfites, or certain anesthetics; who are not pregnant or nursing; and who are willing to have a biopsy before and after dental surgery are eligible for this study. Patients will come to the clinic for one test visit and one treatment visit. During the first visit, a questionnaire will evaluate patients' psychological state, including mood and depression. There will be a clinical examination of their wisdom teeth. A blood sample of 10 milliliters (about 0.4 ounces) will be collected from the forearm to provide DNA material containing genes stored in cells. The primary genetic analysis will be done at NIH, although the DNA collected might also be sent to a laboratory outside NIH. DNA samples will be coded so that names of patients cannot be traced. During the second visit, two of the patients' lower wisdom teeth will be removed. Patients will be given a local anesthetic in the mouth and a sedative given through a vein in the arm. While the mouth is numb, a small piece of tissue will be removed from inside the cheek, near the wisdom tooth. It is the first biopsy. After the two wisdom teeth are removed, a small piece of tubing will be placed into both sides of the mouth where the teeth were removed. Every 20 minutes, for the next 3 hours, the researchers will collect inflammatory fluid from the tubing, to measure the chemicals thought to cause pain and swelling. Also every 20 minutes, patients will rate the pain they feel by answering questions. If there is pain before 3 hours following surgery, they will receive a dose of fentanyl to relieve moderate to severe pain. A second biopsy will occur 3 hours after surgery, to measure changes in chemicals produced in response to surgery. Immediately afterward, patients will receive 30 mg of ketorolac (Toradol) whether or not pain is felt. They will answer questionnaires about pain for 3 hours after receiving the drug, to rate how well it works. They will stay at the clinic up to 6 hours after the surgery. If pain is not relieved with ketorolac, patients will receive a one-time dose of tramadol, a pain medication for moderate to severe pain. After the study procedures are completed, patients will receive pain medication for pain after surgery. Patients will be monitored closely, because all drugs have side effects. Ketorolac is a nonsteroidal anti-inflammatory drug, one that may cause gastrointestinal upset. Fentanyl is a powerful narcotic drug that is safe at the dosage used in this study, but stomach upset, dizziness, and breathing trouble may occur. Also, risks from the biopsy include discomfort from injecting the numbing medicine, infection, and bleeding. There may be discomfort from the sedative injected into the vein, and there may be bruising. Benefits from participating are having wisdom teeth removed at no cost as well as close monitoring before and after surgery. There are no plans to give patients the results of genetic tests or questionnaires. Years of research may be needed before such information has the chance to become meaningful.
The purpose of the study is to assess the efficacy and safety of NGX-4010 applied for 60 minutes for the treatment of postherpetic neuralgia (PHN).
We aim to compare pain management among three groups of ethnic disparity (ED) patients, Hispanics, non-Hispanic Blacks, non-Hispanic Whites, and assess whether the observed association between pain management and race/ethnicity is independent of potentially important confounding variables (e.g., age, sex, insurance status, education). We also aim to assess whether the effect of race/ethnicity on adequacy of pain management is explained by patients' initial pain intensity or by discordance between patient and physician's: a) race/ethnicity; b) perception of patient's pain. To do this 285 patients with long-bone fractures will be recruited in the EDs of one municipal and one voluntary hospital serving an inner-city, disadvantaged population in the Bronx. Data will be collected on pain using self-reported pain and non-verbal pain expressions at baseline, one hour post-baseline, and discharge. Data on analgesics administered, patient and physician characteristics will also be collected. We plan to conduct a chart review of long bone fractures in 2000 and 2001 so that we can analyze the association between race/ethnicity and pain management using the same design as published studies. Comparison of the retrospective and prospective studies will strengthen inferences that can be drawn. We hypothesize that Black and Hispanic patients will be less likely to receive opioid analgesics than white patients.
The purpose of this study is to determine whether dextromethorphan (Neurodex) and quinidine are effective in the treatment of pain of diabetic neuropathy.
Pulsed dye laser (PDL) on the face is painful. For this reason, local anesthesia is commonly used to eliminate or minimize the pain. S-Caine™ Peel (lidocaine 7% and tetracaine 7% cream) is a eutectic formulation of lidocaine and tetracaine. The purpose of this study is to evaluate the efficacy of S-Caine Peel for induction of local dermal anesthesia for PDL therapy in adults.
Injection of dermal filler is used as an aesthetic treatment to fill in unwanted wrinkles and scars. There can be substantial pain associated with dermal filler injections. For this reason, local anesthesia is often used to eliminate or minimize the pain. This anesthesia can be administered by injection or through the use of topical creams and ointments. S-Caine™ Peel (lidocaine 7% and tetracaine 7% cream) is a eutectic formulation of lidocaine and tetracaine. The purpose of this study is to evaluate if S-Caine Peel is effective in providing topical local dermal anesthesia for dermal filler injections in adults.
Lasers are used for non-ablative resurfacing of facial rhytides, atrophic scars, and a variety of epidermal and dermal lesions. Pain associated with the non-ablative laser treatment has been described as moderate to severe. For this reason, local anesthesia is commonly used to eliminate or minimize the pain. S-Caine™ Peel (lidocaine 7% and tetracaine 7% cream) is a eutectic formulation of lidocaine and tetracaine. The purpose of this study is to evaluate if S-Caine Peel is effective in providing topical local dermal anesthesia for non-ablative facial laser resurfacing in adults.
There is pain associated with laser-assisted tattoo removal. For this reason, some form of anesthesia is commonly used to eliminate or minimize the pain. This anesthesia is usually a topical local anesthetic cream or ointment spread over the skin. The purpose of this study is to further estimate the effectiveness of S-Caine™ Peel (lidocaine 7% and tetracaine 7% cream) for treating pain during laser-assisted tattoo removal.
