Filter by:Background: - Sickle cell disease often causes crises, with episodes of pain. Many people with sickle cell disease also have pain between crises. Inflammation is an important part of sickle cell pain. It may be related to levels of nitric oxide. Nitric oxide is a gas in the body that helps relax blood vessels and may be related to the pain from sickle cell disease. Researchers want to study the relationship between blood levels of nitric oxide and pain in people with sickle cell disease. Researchers also want to study how certain genes express themselves related to sickle cell pain. Objectives: - To collect blood samples and other genetic expression information to study sickle cell pain and its relation to nitric oxide levels in the blood. Eligibility: - People at least 18 years of age who have sickle cell disease. - Healthy volunteers at least 18 years of age. Design: - This study requires a screening visit and four study visits scheduled 1 week apart. Each visit will last about 1 hour. - Participants will be screened with a medical history and physical exam. They will complete questionnaires about pain levels (if any). They will also provide blood samples for genetic and other testing. - Participants will have a breath test to see how much nitric oxide they exhale. They will also have a test of their ability to detect small changes in temperature and touch. - Participants will keep a diary to record daily pain levels and pain medicines taken. They will write down what they eat to track foods that contain nitrates (such as meats like ham and bacon and vegetables like beets and spinach). - At each of the four study visit, participants will bring the pain diary, provide blood samples, and have breath nitric oxide tests.
The primary hypothesis is that those patients who choose an interscalene catheter will have less pain postoperatively than those with single injection blocks. Secondary hypotheses examine physical therapy outcomes and incidence of parasthesia or pain following surgery for up to 3 months.
In this study the investigators will be comparing two different types of anesthetic, a numbing eye drop and a numbing gel, to test if they are equally effective or if one has a better outcome in terms of the level of comfort you experience one hour and one day after your surgery. The two medications are commonly used and appear to be equally effective for other types of eye surgery, such as cataract surgery. This study will show if one type of anesthesia is preferred over another by patients getting LASIK. Before your LASIK procedure, you will be given a short questionnaire to determine the baseline comfort of your eyes. In the operating room, one type of anesthetic will be put in one eye, and the other medication will be put in the other eye. Which anesthetic you get in each eye will be chosen in a random way (similar to flipping a coin). After your LASIK surgery, the investigators will ask you if you felt more comfort in your right eye, your left eye, or if they were equal, and the investigators will ask you the same survey questions that were asked prior to your LASIK to get more details about your experience. *Of note- the randomization being done is for which eye will be receiving the lidocaine and which eye will be receiving the tetracaine. Each patient will receive lidocaine in 1 eye and tetracaine in the other eye, the randomization is for each individual eye. This means, of 11 patients in our study, 22 eyes received treatment. 11 eyes received lidocaine and 11 eyes received tetracaine. when we did our comparison, 11 values were used for lidocaine and 11 eyes were used for tetracaine, giving a total of 22 eyes. This is important to note since the randomization refers to EYE for each individual patient, and not for the patient (ie: participant means 1 eye, not 1 person in the descriptions below).
Pain following Cesarean delivery remains the most common post-operative complaint, and the provision of effective and safe analgesia is very important. Pain can impede the mother's ability to mobilise, and to care for and breastfeed her newborn baby. Pulsed electromagnetic field (PEMF) devices have been used in various clinical settings, especially after plastic surgeries, to reduce postoperative swelling and pain, as well as to accelerate wound repair. PEMF therapy is simple to use, cost-effective and has no known side effects. Despite advances in post-operative analgesia, pain relief and maternal satisfaction remain inadequate in some patients. Improving the quality of post-Cesarean analgesia while limiting undesirable side effects will enhance maternal satisfaction and reduce the risk of post-operative complications. The investigators hypothesize that the continuous use of a PEMF device for 48 hours after Cesarean delivery will result in decreased post-operative pain scores on movement at 48 hours.
The purpose of this study is to compare the effectiveness of a more feasible method for reducing the pain and distress of childhood immunization with the standard method in use at the Pediatric Medical Group. A secondary aim is to evaluate the impact of parental involvement on the parent and child satisfaction with the immunization experience. Study Hypotheses: In the standard, pre-kindergarten, two- or three vaccine sequence, there will be no statistically significant group differences between PPT and ST with respect to: 1. Child self-reported pain using the Faces Pain Scale-Revised (FPS-R) scale13 (primary outcome); 2. Parent report of child pain using the FPS-R; 3. Observer-rated child distress and pain using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale14; 4. Parent and child satisfaction with pain management during immunization measured by a 5-point Likert type scales; 5. Time required for completion of immunization from initiation of ST or PPT to 2 minutes after completion of the last injection.
In this controlled study the investigators will examine the analgesic and sensory effects of ultrasound-guided blocks of the iliohypogastric and ilioinguinal nerves with lidocaine in persistent postherniorrhaphy pain patients.
For post-Cesarean analgesia, the investigators will compare the efficacy of single-shot epidural preservative free morphine with a continuous epidural fentanyl infusion. The investigators will be comparing the patient's pain level and satisfaction with the two techniques, as well as the side effects that the patients experience, such as itching, nausea, back pain and respiratory depression.
Patients undergoing deep sedation for outpatient procedures typically receive a combination of benzodiazepines, propofol, and opioids. Side effects of such anesthetics include respiratory depression, nausea and vomiting, and urinary retention, with resultant extended hospital stays and unanticipated admission. The use of dexmedetomidine for deep sedation may increase patient safety by maintaining respiratory drive, while providing sedation, hypnosis, and analgesia. Furthermore, patients may experience decreased pain, nausea, and time to discharge in the PACU, especially if dexmedetomidine decreases the requirement of other drugs such as opioids. The hypothesis of this study is administration of dexmedetomidine during deep sedation for ambulatory hysteroscopic surgery will result in a 50% reduction of intraoperative opioid compared to sedation with propofol.
CUC10-PAN09 will evaluate the safety and efficacy of cryoablation therapy on the relief of epigastric/abdominal pain associated with pancreatic cancer.
While narcotic medication are commonly used for pain control near the time of surgery, there are significant side effects including constipation, nausea, risk of overdose leading to decreased breathing, and risk of addiction to narcotics. Our goal is to explore alternatives to narcotics for perioperative pain for patients undergoing sperm retrieval surgery. We have designed a prospective randomized clinical trial to evaluate how effective the anti-inflammatory medicine celecoxib(Celebrex©) is for pain control near the time of surgery. Celecoxib is known as a COX-2 inhibitor, a drug that belongs to the non-steroidal anti-inflammatory drug (NSAID) class. It is used to reduce swelling and to treat pain. Patients will be divided into two groups: the first group receives a celecoxib pill and the second group receives a sugar pill(placebo). Patients and doctors will be unaware of exactly which pills are given. The patient will complete questionnaires for pain level. By comparing the pain levels we can better understand whether celecoxib (Celebrex©) significantly decreases perioperative pain.
