There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to evaluate the feasibility and sensitivity of nipple-areolar complex (NAC) prospectively due to the section of the dermis after decortication (Schwartzmann's maneuver), in 50 patients undergoing breast reduction surgery.
Oximetry monitoring is common practice in patients undergoing anesthesia. PVI continuous evaluation may be a possibility of agility and ease of obtaining accurate information about the state of cardiovascular responsiveness to volume expansion. This prospective and randomized study will try to demonstrate that the assessment of PVI is a simple and cost-saving method as compared to cardiac output or oxygen delivery monitoring technologies. Such a simple approach has therefore the potential for widespread application as it is not routinely feasible for anesthetists to use cardiac output or oxygen delivery monitoring technologies in many institutions, as well as in many countries.
To evaluate the efficacy and the safety of using a single, intravenous 5mg dose of zoledronic acid in managing pain in Complex Regional Pain Syndrome patients.
The purpose of this study is to determine whether resistance exercise are effective in combating the decline in muscle strength during an exacerbation of Chronic Obstructive Pulmonary Disease (COPD).
The aim of this study was to investigate the effects of using positive pressure in the preoperative, intraoperative and postoperative morbidly obese individuals undergoing gastroplasty. It is believed that the application of these devices before, during or after surgery can help to improve the lungs and reduce pulmonary complications after surgery to reduce the stomach.
CHECKLIST-ICU will be a cluster randomized trial to ascertain whether the use of an intervention including 1) checklists with assessment of daily goals during the multidisciplinary visit, and 2) clinician prompting can reduce in-hospital mortality of patients admitted to intensive care units (ICUs). The investigators also aim to describe participant ICUs in terms of the standards for intensive care units proposed by the Brazilian National Health Agency (ANVISA).
The purpose of this study is to determine whether sugammadex reverses a profound neuromuscular blockade induced by rocuronium in patients with end-stage renal disease just as effectively and safely as it does in patients with normal renal function.
Phase 3, unicentric, randomized clinical trial, with allocation concealment and intention-to-treat analysis to evaluate the efficacy of videolaparoscopic Roux-en-Y Gastroplasty to decrease the prescription of antihypertensive drugs maintaining normal levels of blood pressure, decrease systemic arterial blood pressure and other risk factors for cardiovascular events compared to clinical treatments of patients with arterial hypertension.
Muscle performance is largely influenced by modulations in gene expressions of muscle tissue. In this context, low-level laser therapy has been used to improve muscle performance in experimental models and human researches. Thereby, the investigators examined modulations on global gene expression of muscle tissue influenced by exercise associated to low-level laser therapy.
This Randomized, pragmatic, multicentric with blinding of patients and health professionals, intention-to-treat analysis has by primary endpoint to evaluate whether the aspirin use reduces the intensity of organic dysfunction measured by the variation of the SOFA score starting from the day of admission to the seventh day. Secundary endpoint: To evaluate if the aspirin use reduces the time of mechanical ventilation, length of stay in the ICU and in the hospital. In addition, to evaluate the safety of its administration regarding the occurrence of bleeding. The data will be collected directly from the chart of the patients admitted to the ICU. Data quality assurance will be made through periodic verification, aiming for complete and consistent data. The centers will receive periodic reports for adequacy of potentially inconsistent or incomplete data. The baseline SOFA of patients with sepsis is 8.8 with a standard deviation of 3. The expected reduction in the control group in the SOFA at day 7 is 2 points. Considering a power of 80% and a level of significance of 0.05, it is estimated that 109 patients will be needed in each group. A total of 218 patients will compose the sample. All analyzes will follow the intention-to-treat principle. We will evaluate the effect of aspirin compared to placebo on primary and binary outcomes by means of relative risks, 95% confidence intervals and chi-square tests. For continuous outcomes with normal distribution, we will present the mean difference, 95% confidence interval and P value calculated by t test. For continuous outcomes with asymmetric distribution, we will perform Wilcoxon test.
