Filter by:The goal of this clinical trial is to learn about the effect of ketamine on intraoperative motor evoked potentials in adult patients undergoing thoracolumbar spinal fusions. Participants will undergo a standard anesthetic. In addition to the standard anesthetic, the patients will be administered increasing doses of ketamine with motor-evoked potentials being measured at each dose, to assess any impacts.
Unplanned re-operation is one of the common negative indicators reflecting the quality and safety of surgery in the medical industry and has become one of the ten goals for the improvement of national medical quality and safety in China since 2022, while about 40% of unplanned re-operations in Peking University Third Hospital in recent years occur in spine patients of the orthopedics department. This project intends to establish a high-quality and sustainable ambispective disease cohort for spine surgery in Peking University Third Hospital based on the unplanned re-operations that occurred in the Orthopedics Department of Peking University Third Hospital from January 2012 to December 2025. The investigators further summarize and analyze clinical causes and risk factors of re-operations, aiming to explore scientific coping strategies and provide reference for continuous improvement of medical service quality.
Vertebra is one of the most common site of metastatic disease, which may cause severe pain or neurological deficit. Debulking surgery usually has better local control and survival benefit as compared with decompression or radiotherapy. However, debulking surgery often accompany with massive blood loss, which may cause hemorrhagic shock or death. The major bleeding point during operation including tumor parenchyma, arteries that are difficult to ligate, and epidural venous plexus. Vascularity of tumor parenchyma had been associated with increased intraoperative blood loss, on the other hand, there is a lack in the literature regarding to evaluation of the size, flow and pressure of epidural venous plexus, and their changes after embolization.
Cervical spine tumor is a small sample of tumor disease with low incidence, great harm, and complex anatomical structure. It is very difficult to identify and classify benign and malignant cervical spine tumors clinically. The deep learning model we constructed in the early stage has a higher accuracy rate for the image diagnosis of cervical spondylosis with a large number of cases, and a better clinical application effect, but the accuracy rate for cervical spine tumors with a small number of cases is lower. The reason may be the amount of data. With limited tasks, the traditional deep learning model is difficult to play an effective role. Based on this, we propose to build a small sample-oriented deep learning model to assist clinicians in the diagnosis of cervical spine tumors with multimodal images, and to evaluate the benign and malignant tumors.
Background: Brain and spinal cord tumors are uncommon. But they contribute substantially to cancer deaths in the U.S. in children and adults. Little progress has been made in treating brain tumors. Researchers want to learn more about these tumors by studying people who have them. Objectives: To understand brain and spinal cord tumors better and uncover areas for further research. Also, to connect people with these tumors to doctors who can help them manage their illness and give them new treatment options. Design: Participants will have an initial (baseline) visit. They will have their medical history taken and undergo physical and neurological exams. They will have blood tests. They may have scans (imaging studies) of the nervous system. If participants have urine or cerebrospinal fluid collected during their regular care, researchers may save some. Brain tumor tissue from a prior surgery may be studied. Genomic DNA testing will be done on samples. Results will be linked to participants medical and/or family history. The number of study visits at NIH will depend on the wishes of participants and their local doctors. Participants will take a brain tumor survey on a computer. They can take it all at once or in 6 separate sections. Participants will answer questions about their general well-being. They will answer questions to learn if they have symptoms of depression or anxiety. Physicians will discuss test results with participants. They will recommend management and treatment options.
Recently intraoperative motor evoked potential monitoring (MEP) is widely used to reduce neural damage during neurosurgery. As neuromuscular blockade(NMB) during MEP monitoring decreases the amplitude of MEP, partial NMB is usually maintained during general anesthesia. Continuous infusion of NMB agent is preferred than bolus infusion during MEP monitoring. There are a lot of NMB agents in clinical use. But there have been no reports about the effect of changing NMB agent on efficacy of MEP monitoring. Therefore, the investigators performed a randomized controlled trial to evaluate the effect of changing NMB agent on the variability of MEP amplitude during neurosurgery.
Within defined groups of primary malignant and benign bone and soft tissue spine tumors, what variables (clinical, diagnostic, therapeutic, and/or demographic) are associated with overall survival?
