Driving Pressure in Trauma
Sever Chest TraumaMechanical VentilationTraumatic chest injuries are responsible for significant morbidity and the cause of trauma-related death in 20%-25% of cases. Thoracic trauma can include multiple injuries, mainly osseous (ribs, sternal fractures, flail chest), pulmonary contusions or lacerations, pneumothoraces and pleural effusions, and sometimes involve wounds to the heart and vessels (aortic dissection, cardiac contusion) or diaphragm. Following trauma, patients with thoracic injuries are at risk of developing acute respiratory distress syndrome (ARDS). This worsening of respiratory function can lead to requirement for mechanical ventilation. In addition, changes to gas exchange may also be generated or aggravated by mechanical ventilation as a result of barotrauma, biotrauma, or ventilation-associated pneumonia. Many mechanical ventilation strategies have been tried in trauma patients in the last 30 years to determine the optimal method of maximizing gas exchange with minimal lung damage. The driving pressure of the respiratory system has been shown to strongly correlate with mortality in a recent large retrospective ARDSnet study. Respiratory system driving pressure [plateau pressure-positive end-expiratory pressure (PEEP)] does not account for variable chest wall compliance especially in cases of chest trauma. Esophageal manometry can be utilized to determine transpulmonary driving pressure. A recent study suggests that utilizing PEEP titration to target positive transpulmonary pressure via esophageal manometry causes both improved elastance and driving pressures. Treatment strategies leading to decreased respiratory system and transpulmonary driving pressure at 24 h may be associated with improved 28 day mortality. However, currently no specific study with chest trauma patients exists. We propose to investigate the effect of hight transpulmonary driving pressure on duration on mechanical ventilation, length of stay and mortality in patients with sever chest trauma.
Association of Tissue Oxygen Saturation With Postoperative Acute Kidney Injury in Double Valves...
Acute Kidney InjuryTo investigate the relationship of tissue oxygenation of different organs and tissue beds (e.g., a tissue bed on the arm vs. leg vs. flank tissue bed(s) and renal tissue bed, and thus can be used as a surrogate of renal tissue oxygenation monitoring.
Physical Activity on Heart Rate Variability in Patients With Severe Acquired Brain Injury
Acquired Brain InjuryConsciousness1 moreThis study aims to explore autonomic cardiovascular regulation, through measures of heart rate variability (HRV), during different passive and active activities in patients with severe acquired brain injury and a low conscious state. Data from active rehabilitation will be compared with passive periods of rest as well as nightly variance during a continuous 5-day period.
Implementing a School Prevention Program to Reduce Injuries Through Neuromuscular Training
Wounds and InjuriesAdolescent3 moreThe purpose of this study is to evaluate the effectiveness of a neuromuscular training program in decreasing sport and recreational injuries and improving healthy outcomes in junior high school students (grades 7 to 9). The neuromuscular training program is implemented as a 15-minute warm-up at the beginning of the students' physical education classes over a three-month period. This study is a randomized controlled trial design, involving twelve schools over a three-year period. Upon enrolment into the study, schools are randomly assigned to the intervention (neuromuscular training) group, or the control group. The control group includes a standard-of practice warm-up consisting of aerobic components and static stretching. A study athletic therapist visits the schools each week to assess and record information on any injuries sustained by study participants. Baseline health and physical fitness is measured at baseline, and again at 3-month follow-up in study participants to assess changes over the course of the program.
A Novel Device for Surveillance of Vascular Access Sites for Bleeding
Dialysis; ComplicationsWound Complication3 moreBackground Bleeding is often encountered after vascular access procedures for dialysis and fatal episodes of haemorrhage has been reported. A technological solution was sought to monitor for such rare but potentially catastrophic incidents. A novel device, BWATCH, was developed to detect fresh blood from wounds. Aims The aim of this clinical trial was to evaluate the sensitivity and specificity of the device in detecting bleeding in a clinical environment. Methods This a prospective, observational study on inpatients who will have a dialysis catheter inserted or removed. The device will be placed over the dressing for at least 6 hours. An alarm will be triggered if the device detects moisture and wavelength of light reflected specific for haemoglobin.

Spironolactone on Acute Kidney Injury in Critically Ill Patients
Acute Kidney InjuryThis study was designed to evaluate the effect of spironolactone administration in the incidence and severity of AKI in patients critically ill with invasive mechanical ventilation (IMV) in the critical care unit. Patients in critical care unit (CCU) are the most at risk of developing AKI. In most cases a mechanism of ischemia/reperfusion has a central role in the development of AKI. Aldosterone has traditionally been recognized as a mediator that maintains water and sodium homeostasis. Nevertheless, there are enough evidence in humans and experimental models that aldosterone might mediate detrimental effects on renal function and structure in pathophysiological conditions. Indeed, several experimental studies from our laboratory have shown that mineralocorticoid receptor blockade protects the kidney against ischemia/reperfusion injury. The aim of this study is to know: o If mineralocorticoid receptor blockade may reduce the incidence and severity of AKI in critically patients with IMV in CCU. You may be able to enter in this study if: You are at least 18 years old. You are male or female You are with IMV. You are in CCU. Your serum K is less than 4.5 mEq/L Your BP is >90/70 mmHg You cannot enter this study if: You have CKD You have AKI This study will recruit 90 patients from Instituto Nacional de Ciencias Médicas Salvador Zubiran in México City. The study will begin in April 2017. The patients will be randomized to one of 2 groups of treatment (Spironolactone 25 mg or placebo). All treatments looks identical (1 capsule), will be administered through the nasogastric tube. Neither the patients nor their doctors will be able to know or decide which group you are in. You will receive the medication during the first five days of stay in the critical care unit. As part of this trial, the doctors will ask your permission to get a sample urine during this days. They will use the samples to do tests in the laboratory (different to routine tests) that may help them to compare renal function and biomarkers of renal injury. Your participation will end 10 days after your entry into the critical care unit. The most common side effect of spironolactone is hyperkalemia.
