Intra-Articular Adrenaline Versus Tourniquet in Knee Arthroscopy: A Cohort Study
Arthroscopy has become one of the most commonly performed orthopedic surgeries in the world due to it being a minimally invasive technique. Clear visualization is crucial for both safe and efficient arthroscopic procedures. Pneumatic tourniquet has been widely used in knee arthroscopic surgeries to obtain bloodless surgical field, improve visualization, and thereby surgical time. However, complications from tourniquet use are not uncommon, particularly in patients whose procedure takes longer than 60 minutes. Using a tourniquet could increase problems, such as electromyographic alterations, nerve compressions, arterial occlusions, delayed muscle recovery, and muscle weakness. Intra-articular adrenaline injection creates a bloodless field by reducing local perfusion through its vasoconstrictive properties, mimicking the effect of a tourniquet. It appeared to be a potentially effective and safe option. Therefore, this study aimed to evaluate intra-articular adrenaline infiltration as an alternative for achieving a bloodless field without tourniquet-related side effects, in terms of clinical efficacy, operative duration and safety. We would compare intra operative visibility and safety of intra articular adrenaline (1:200,000) injections with use of a tourniquet in arthroscopic knee surgeries. Comparison is made between one group that received standard tourniquet application and another group that received intra articular adrenaline injection. Then the intraoperative visibility in these two groups is compared using tools like surgeon visual analogue score and amount of irrigation fluid required. The effectiveness and safety of the method used is compared using appropriate statistical tools. Null Hypothesis: There is no difference in intraoperative visibility and safety during knee arthroscopic surgeries with standard tourniquet application versus intraarticular adrenaline injection. H0: outcome in Adrenaline group =\< outcome in Tourniquet group Alternative Hypothesis: Intra articular adrenaline injection is better than tourniquet use in arthroscopic knee surgeries with respect to operative field visibility and safety. H1: outcome in Adrenaline group \> or (not less than) outcome in Tourniquet group

Premedication With N-acetylcysteine and Simethicone to Improve Mucosal Visualization in Elective Upper Endoscopy
The goal of this randomized, double-blind, placebo-controlled clinical trial is to assess whether the combination of N-acetylcysteine and simethicone improves mucosal visibility during upper gastrointestinal endoscopy in adults aged 18 to 99 years of both sexes, including both healthy individuals and those with non-bleeding gastrointestinal symptoms. The main questions this study aims to answer are: Does pre-endoscopy administration of N-acetylcysteine/simethicone improve mucosal visualization based on the Toronto Upper Gastrointestinal Cleanliness Score (TUGS)? Is this combination safe and well tolerated in this patient population? Researchers will compare patients receiving N-acetylcysteine (600 mg) and simethicone (100 mg) orally 20-60 minutes before the procedure with those receiving placebo (water) to determine if there is a significant improvement in TUGS scores. Participants will: Receive a single oral dose of either N-acetylcysteine/simethicone or placebo prior to endoscopy Undergo a routine upper GI endoscopy Have mucosal cleanliness evaluated using the TUGS scoring system Be monitored for any adverse events or intolerance

UTERINE EVALUATION FOR THE IDENTIFICATION OF PATHOLOGY. This Study Will Compare the Intrauterine Pathology Detection Rate Between Standard of Care Hydrosonography, and a New Visual Saline Infusion Device Providing Direct Visualization of the Uterus.
This is a prospective, single center, multiple arm cohort study intended to compare the diagnostic accuracy of a Visual Saline Infusion Device (VSI) device, vs standard of care Hydrosonography in reproductive aged women to identify pathology in the uterus.
