| NCT00014040 ↗ | Nitric Oxide Inhalation Therapy to Relieve Chest Pain in Patients With Coronary Artery Disease | Completed | National Heart, Lung, and Blood Institute (NHLBI) | Phase 2 | 2001-04-01 | This study will test whether inhaling nitric oxide gas can improve blood flow to the heart, ventricular function, exercise tolerance in patients with coronary artery disease and chest pain that has not improved with medical or surgical therapy. Patients with coronary artery disease who have chest pain despite treatment with medicines and angioplasty or surgery may be eligible for this study. Those enrolled will receive monetary compensation for their participation in this study. The duration of the study is 5 days, with 2 testing periods lasting 2 days each. During one of the periods, the study participants will breathe nitric oxide mixed with room air through a face mask during the tests. During the other period, the participants will breathe room air alone through a face mask during the tests. At least 1 day will separate the treatment periods. During each of the 2 treatment periods (nitric oxide and room air), participants will undergo 4 tests to determine whether the treatment improves the heart's response to stress with increased heart rate and contraction. Approximately one hour before each of the tests, participants will breathe either nitric oxide mixed with room air or room air alone through the face mask, and continue the inhalation treatment while each test is being performed. The face mask will be removed at the end of each test. On the morning of the first day of each treatment period, participants will have a special echocardiogram with imaging of the heart. The echocardiogram will be performed during an infusion of dobutamine, a medicine that increases heart rate and contraction, and serves to stress the heart. This manner of stress testing is commonly used in hospitals around the country to determine if walls of the heart are receiving sufficient blood supply. That afternoon, participants will undergo a magnetic resonance imaging (MRI) study of the heart. The MRI will determine the heart's blood flow and contraction while receiving the same dosage of dobutamine as was used earlier in the day. On the morning of the second day of each treatment period, participants will exercise on a treadmill until moderately uncomfortable chest pain is reported. Later that morning, participants will undergo cardiac catheterization. For the cardiac catheterization, a long tube (catheter) will be placed into a vein of the neck once the skin is numbed with xylocaine. This tube will be positioned within the right atrium of the heart and into a tube-like structure called the coronary sinus, where venous blood exits the heart muscle. A small catheter will also be placed in an artery of the upper forearm after the skin has been numbed with xylocaine. Blood samples will be taken to allow us to measure the amount of nitric oxide transported in the blood. The blood samples will be drawn (through the tube in the heart and through the small tube in the artery) at the beginning of the study and during infusion of dobutamine to stress the heart. The dose of the dobutamine infusion will be the same dose used in the previous day's stress studies. After the completion of the first treatment period, we will stop testing for at least one day. Participants will begin the second treatment period with the inhalation treatment not received during the first treatment period. |
| NCT00219713 ↗ | Evaluation of Pain Intensity During Bone Marrow Biopsy Performed With Inhalation of Pre-Mixed 50 Per Cent Nitrous Oxide and Oxygen Mixture. | Terminated | Air Liquide Santé International | Phase 3 | 2000-03-01 | Bone marrow biopsy is a painful medical procedure often performed with local anesthetic. Therefore a double-blind, randomized, controlled trial was carried out in 330 adult patients who where referred for bone marrow biopsy and aspiration. 164 were assigned to inhale an equimolar mixture of nitrous oxide and oxygen and 166 to inhale a placebo. Pain measurement used visual-analogue pain scales, which involve rating the intensity of pain on a horizontal ruler |

| NCT00456872 ↗ | Contrast of Buffered Vs. Unbuffered Lidocaine in Bone Marrow Biopsies | Completed | Ohio State University Comprehensive Cancer Center | N/A | 2004-12-01 | Oncology patients require numerous invasive procedures throughout their disease process including bone marrow biopsies (BMB). BMB.s are performed by a significant number of health care providers. One of the biggest concerns for health care providers is to improve patient comfort. The goal of this study was to reduce pain during BMBs. Specific aims of the study were to determine if there is a difference in patients' perceived pain during injection of the pre-procedure anesthetic when buffered versus unbuffered lidocaine is administered to patient's receiving bone marrow biopsies. A double blind, experimental crossover design was used to examine the difference in pain levels when using buffered versus unbuffered lidocaine prior to the bilateral bone marrow biopsy procedure. Based on a power analysis for a paired t-test, a convenience sample of 48 patients was enrolled into the study. Patients served as their own control. The site of first biopsy, and which lidocaine solution was administered first, were randomized. A 100mm visual analogue scale (VAS) was used to measure pain. All data has been collected, are currently under analysis, and results will be completed in August 2006. Differences in groups will be examined using a paired t-test. A demographic questionnaire was used to gather select demographic variables. Correlative studies will be done to examine the relationship between the patient's perceived pain scores and several exploratory variables. Results of this study may change the current type of anesthetic used pre-BMBs thus improving patient comfort. |
| NCT00465439 ↗ | Safety/Efficacy Study of Local Anesthetic Prior to Femoral Artery Sheath Removal | Completed | Hamilton Health Sciences Corporation | N/A | 2007-05-01 | This randomized controlled trial will examine the impact of local anesthetic on the frequency of vasovagal reactions and the patients perception of pain during femoral arterial sheath removal after percutaneous coronary intervention. |
