Filter by:The aim of the present study is to access the success rate of ultrasound-guided thoracic epidural catheter insertion, using fluoroscopy.
The purpose of this study is to compare the results of combining two anesthetic medications (dexmedetomidine and propofol) in low doses with a standard dose of a single drug that is commonly used to provide sedation/anesthesia for MRI studies in young children (propofol). The drugs used for the MRI scan in this study will be chosen randomly. Half the patients will receive small doses of propofol and dexmedetomidine. The other half will receive propofol administered constantly throughout the scan. Other drugs that may be used include sevoflurane and nitrous oxide at the start of the sedation (for placing an intravenous), lidocaine (to reduce the pain of propofol injection) and glycopyrrolate (to prevent the heart rate from decreasing too low. The investigators will record 5 additional blood pressures and heart rates. If additional medications are required to complete the scan, the investigators will administer whatever is necessary. At the end of the study, the investigators will have an observer record the time it takes for participants to spontaneously open eyes , to be able to drink liquids and/or eat and to behave as before the study. Also, it is very important that the investigators find out from participants about changes in behavior, or if eating or sleeping habits were unusual following completion of the study. For that reason, the investigators will call participants in a day or so following the MRI scan. The investigators expect to recruit 40 children between the ages of 12 and 72 months for the study and hope to have the study completed in December 2018.
This study will test the effectiveness of an experimental treatment for peritoneal cancer involving surgical removal of the tumor, perfusion of the abdomen during surgery with a heated solution of the drug cisplatin, and post-surgery combination chemotherapy in the abdomen with fluorouracil (5-FU) and paclitaxel. Patients with certain peritoneal cancer whose tumors are confined to the abdomen may be eligible for this study. Candidates are screened with a medical history and physical examination, including blood tests, electrocardiogram and possibly bone scan, brain magnetic resonance imaging (MRI), and chest, abdomen and pelvic CT scans. Participants undergo surgery to remove as much tumor as possible. Part of the intestines, pancreas, stomach or the entire spleen may also be removed if they are affected. During surgery, after the tumor has been removed, two catheters (thin plastic tubes) are placed in the abdomen. A chemotherapy solution containing the anti-cancer drug cisplatin heated to a temperature of about 108.6 degrees (10 degrees above normal body temperature) is then delivered into the abdomen through one catheter and drained through another. During treatment, a drug called sodium thiosulfate is given through a vein to reduce the risk of side effects of cisplatin, particularly kidney damage. After 90 minutes of bathing the abdomen with this solution, the drug is rinsed from the abdomen and the catheters removed. Another small catheter is then placed and left inside the abdomen with one end coming out through the skin. Seven to 12 days after the operation, the anti-cancer drugs 5-FU and paclitaxel are given through this catheter. After complete recovery from the surgery, the catheter is removed and the patient is discharged from the hospital. Clinic visits are scheduled for periodic follow-up examination, imaging, and tests 3 and 6 months after surgery and every 6 months for up to 5 years as long as the disease does not worsen. Patients whose disease progresses are taken off the study and referred back to their local physician or referred for alternative care or other research studies. Patients are also asked to assess how this therapy affects their general health and well being. This will require filling out two quality-of-life (QOL) questionnaires before surgery and again at each follow-up visit after surgery. Each questionnaire takes about 15 minutes to complete.
