Summary: The goal of this study is to develop better methods of diagnosis, localization, and treatment for pheochromocytomas. These tumors, which usually arise from the adrenal glands, are often difficult to detect with current methods. Pheochromocytomas release chemicals called catecholamines, causing high blood pressure. Undetected, the tumors can lead to severe medical consequences, including stroke, he...

Summary: The purpose of the study is to evaluate the efficacy of R.E.C.K (ropivacaine epinephrine clonidine ketorolac) vs Exparel during robotic partial and radical nephrectomy in a single institution, prospective, randomized trial. The study will evaluate post operative Numerical Rating Score (NRS) pain scores, post operative pain medication intake (opioids and over-the-counter pain medicines) and length ...

Summary: This project is a multicenter, three armed, prospective randomized control trial studying the effectiveness of a long-acting local anesthetic cocktail in patients undergoing operative fixation of ankle fractures.

Summary: This study is a pragmatic clinical trial examining the comparative effectiveness of two stimulant medications (methylphenidate and amphetamine) in the treatment of ADHD in children and adolescents with autism. Using a sequential, multiple assignment randomization trial (SMART) design the study will not only assess these two medications but also the role of an increasingly popular class of ADHD med...

Summary: Electroconvulsive therapy (ECT) is a highly effective treatment for some psychiatric disorders like major depressive or bipolar disorder, but may lead to agitation and delirium after the procedure in up to 65% of patients. This can have negative side effects and be dangerous for patient and attending staff. Clonidine, a central-acting alpha2-receptor agonist, is an approved antihypertensive medica...

Summary: Hypothesis: Veterans with PTSD prescribed clonidine will demonstrate improvements in PTSD symptoms, including daytime, nighttime, and sleep-related behaviors.

Summary: This clinical trial aims to evaluate the effectiveness of an ultrasound-guided nerve block technique as the sole anesthetic method for patients undergoing outpatient umbilical hernia surgery. The procedure, called rectus sheath block (RSB), involves injecting local anesthetic near the abdominal muscles to reduce pain during and after surgery. The study will compare two groups of adult patients: on...

Summary: The goal of this phase II clinical trial is to study the effectiveness of a treatment with Serratus Plane Block (SPB) or Botox-A in comparison with capsaicin for the control of chronic neuropathic pain of post-mastectomy syndrom, that is not adequately managed by systemic treatment alone. The primary outcome will be the pain evaluation at 8 weeks. 123 patients with chronic neuropathic pain of post...

Summary: Attention deficit hyperactivity disorder (ADHD) or syndrome (ADHS) is a symptomatically defined condition that - if untreated - is linked to a significantly increased risk of traffic accidents. In a recent umbrella review, where data from reviews and meta-analyses on 21.142.129 adults was assessed, a pooled prevalence of 3.1% of ADHD in adults was estimated. Considering that globally around 1.35 m...

Summary: The purpose of this study is to examine the hypothesize that 4 weeks of sympathetic nerve activity (SNA) inhibition (oral clonidine) will cause a significant reduction in circulating blood concentrations and endothelial cell expression of inflammatory markers (e.g., TNF-α, IL-6). Our study is a prospective study using a randomized, double-blinded design to test 4 weeks of SNA blockade (oral clonid...

Summary: Hot flashes present a considerable problem for many breast cancer patients; these symptoms may be intensified by hormonal therapies, such as aromatase inhibitors or tamoxifen. This study examines the value of solifenacin (a muscarinic acetylcholine receptor antagonist) in reducing hot flashes, compared with clonidine (a medication often used for treating hot flashes).

Summary: The goal of this clinical trial is to learn if there is a difference in morphine requirements in patients after upper extremity surgeries including shoulder arthroscopy. The main question it aims to answer is whether there is a difference between Interscalene brachial plexus blocks with the addition of buprenorphine, dexamethasone, and clonidine and the same block without the adjuvant.
