There are about 2320 clinical studies being (or have been) conducted in Chile. 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.
Deep sedation in patients with COVID-19 may be challenging in many aspects. The use of an EEG-based protocol to guide deep sedation may be useful in this particular population, considering their unusually high sedation requirements. In the present trial, we aim to evaluate an EEG-based protocol to guide deep sedation in patients with COVID19, using to EEG derived parameters that are displayed in the BIS monitor: Suppression Rate and Spectral Edge Frequency. The protocol is designed to both minimize the suppression rate along with maintaining a spectral edge frequency over 10 Hz. The use of this protocol may reduce the amount of sedatives administered and, therefore, diminish the time needed for the weaning process.
This is a phase 3, multicenter, randomized, double-blinded, placebo-controlled, parallel-group trial to evaluate the efficacy, safety, and effect on QoL/PRO of efgartigimod PH20 SC treatment in adult patients with primary ITP.

The primary objective of this study is to generate evidence demonstrating the domain specification (via modern psychometric methods), reliability, validity, and responsiveness (within-subject meaningful change) of the Patient-Reported Outcome (PRO) endpoints.
The study will evaluate the efficacy, safety, and immunogenicity of two vaccination schedules of an inactivated vaccine against SARS-CoV-2 infection in adults. Two doses of the vaccine will be administered in a 0,14 and a 0,28-day schedule. Follow-up of safety and efficacy will be assessed for 12 months after the first dose. Immunogenicity will be studied in a subgroup of participants.
Acute respiratory distress syndrome (ARDS) is a form of acute lung injury of inflammatory origin, which represents a public health problem worldwide due to its prevalence, and its high mortality rate, close to 40%. Mechanical ventilation is a fundamental therapy to improve gas exchange, however, it can also induce further lung injury, a phenomenon known as ventilator induced lung injury (VILI). The limitation of tidal volume is the strategy that has shown the greatest decrease in mortality and is the cornerstone of protective ventilation. However, the respiratory rate, a fundamental parameter in the programming of the mechanical ventilator, has not been evaluated in most of the main clinical studies to date. Moreover, the natural clinical response to the use of a low tidal volume strategy is the increase in respiratory rate, which may harm the lung as it increases the energy applied to the lung parenchyma. The investigators hypothesize that the use of a lower respiratory rate, tolerating moderate hypercapnia, is associated with less VILI, measured by the release of proinflammatory mediators at the systemic level (biotrauma), compared to a conventional higher respiratory rate strategy in patients with moderate to severe ARDS. This effect is mediated by lower energy applied to the pulmonary parenchyma. To confirm this hypothesis the investigators propose a prospective cross-over clinical trial in 30 adult patients with ARDS in its acute phase, which will be randomized to two sequences of ventilation. Each period will last 12 hours, and respiratory rate (RR) will be set according to PaCO2 goal: 1) Low RR, PaCO2 60-70 mmHg; and 2) High RR, PaCO2 35-40 mmHg. Protective ventilation will be applied according to ICU standards under continuous sedation and neuromuscular blockade. Invasive systemic arterial pressure and extravascular lung water will be monitored through an arterial catheter (PICCO® system), and airway and esophageal pressures and hemodynamics continuously measured throughout the protocol. The main outcome will be Interleukin-6 in plasma. At baseline and at the end of each period blood samples will be taken for analysis, and electrical impedance tomography (EIT) and transthoracic echocardiography will be registered. After the protocol, patients will continue their management according to ICU standards.
The aim of this observational study is to evaluate the physiological and clinical effects of prone position in awake patients with respiratory failure due to COVID-19.
This project seeks to evaluate the trajectories of suicidal ideation and attempts in adolescent patients with psychiatric disorders in secondary care controls in the Maule region, in relation to clinical factors (depressive symptoms, anxiety, stress, psychiatric comorbidity, mistreatment or abuse, history of psychiatric disorders and pharmacological treatments); psychological (parenting styles, impulsivity, barriers in seeking help and emotional regulation), and neuropsychological (executive function-decision making).
Although COVID-19 affects primarily the respiratory system, several studies have shown evidence of cardiovascular alterations. Increased troponin levels were observed in a significant proportion of patients and this alteration was associated with higher mortality. In addition, case reports of cardiogenic shock or fulminant myocarditis have been communicated. Likewise, pulmonary embolism (PE), right ventricle dilation, and acute cor pulmonale (ACP) have also been described. Therefore, investigating cardiac function in COVID-19 is highly relevant, particularly in critically ill patients who are usually under sedation and mechanical ventilation, which may further impair cardiovascular function. Thus the objective is to determine the prevalence of left ventricle dysfunction and acute cor pulmonale, and its association with respiratory mechanics, in 100 consecutive critically ill COVID-19 patients, who were assessed with critical care echocardiography (CCE) within the first 24 hours of mechanical ventilation.
