Active clinical trials for "Wounds and Injuries"

Post-traumatic brain hypoxia/ischemia develops hours after traumatic brain injury (TBI), and its intensity is directly related to the neurological outcome. The thresholds for irreversible tissue damage following TBI indicate a particular vulnerability of injured brain. Improving brain oxygenation after severe TBI is the focus of modern TBI management in the intensive care unit (ICU). The calculation of cerebral perfusion pressure (CPP), with CPP = mean arterial pressure (MAP) - intracranial pressure (ICP), has become the most used estimator of cerebral blow flow. To prevent ischemia due to elevated ICP, current international guidelines recommend maintaining CPP at 60-70 mmHg and ICP below 20 mmHg. However, episodes of brain hypoxia/ischemia, as assessed with brain tissue oxygen pressure (PbtO2) measurements, might occur despite optimization of CPP and ICP, and have been independently associated with poorer patient outcome. PbtO2 values lower than 15 mmHg for more than 30 minutes were shown to be an independent predictor of unfavorable outcome and death. The aggressive treatment of low PbtO2 was associated with improved outcome compared to standard ICP/CPP-directed therapy in cohort studies of severely head-injured patients. On the basis of these findings, it is hypothesized that an early optimization of brain oxygenation, together with keeping ICP and CPP within recommended values, could reduce the volume of vulnerable lesions following severe TBI and possibly improve neurological outcome.

Significance: The long term objective of this study is to improve physical therapy and fitness programs in people with spinal cord injury. The results of the study will demonstrate the importance of matching blood flow to a muscle with exercise of that same muscle. Scientific Objective: The objective of the study is to measure how the body regulates bloodflow to a muscle during exercise. We intend to study these effects by triggering blood flow changes during movement, and measuring bloodflow changes during exercise in people with spinal cord injury. We will also look at the long term effects of different exercise programs on bloodflow during exercise. Study Populations: This study will involve people with partial spinal cord injury and age and sex matched controls without injury. Specific Aims: Aim 1 will be to measure bloodflow during exercise of the legs (below the injury). This aim will examine the control of bloodflow and muscle contractions and how it changes after spinal cord injury. Aim 2 will then look at changes in bloodflow during exercise after training. Three different eight week exercise training programs will be tested including 1) upper body ergometry, 2) treadmill training with exertion level matched to the upper body ergometry and 3) treadmill training with heart rate matched to an initial test of upper body ergometry.

The purpose of this study is the evaluation of the safety of autologous tissue-engineered dermal substitutes "denovoDerm" (first arm) and dermo-epidermal skin substitutes "denovoSkin" (second arm) transplanted onto the wound bed in children and adults.

Postoperative pain and time taken to return to normal activities after laparoscopic surgery are significantly shorter. Wound infections still occur and contribute to prolonged hospital stays and morbidity. Typically, port incision sites are covered with a standard dressing (approximating strips and a gauze). Although the umbilical wound infection rate in laparoscopic surgery is considered to be low, a recent study by Muensterer and Keijzer showed that the umbilical wound infection rate after single incision laparoscopic appendectomy in children is approximately 7%. In the same retrospective study, the investigators demonstrated that a simple low cost vacuum dressing can significantly reduce the infection rate. The aim of this prospective randomized controlled trial is to determine if the simple vacuum dressing is superior to a standard dressing in reducing laparoscopic postoperative umbilical wound infections. All patients under 17 years of age undergoing a laparoscopic operation in the Children's Hospital will be randomized to a standard postoperative dressing or a standard postoperative dressing with vacuum applied to it. The vacuum will be applied with a 22g needle on a 10ml syringe passed percutaneously from outside the dressing into the gauze and the air around the gauze is evacuated. The umbilical wounds will be evaluated 8-10 days postoperatively in the clinical research unit of the Manitoba Institute of Child Heath according to a standardized and validated wound evaluation tool from the Canadian Center for Disease Control. Primary outcome measure in this study is postoperative wound infection. A sample size calculation using the retrospective data demonstrated that the investigators need 275 patients in each group for the Chi-squared test to have an 80% chance of detecting a difference in wound infection rate of 6% at the 5% level of significance. Based on the annual number of laparoscopic operations in the Children's Hospital (around 400) the investigators anticipate completing the inclusion of patients within a two-year period.

The effect of intrathecal transplantation of autologous adipose tissue derived mesenchymal stem cells in the patients with spinal cord injury, Phase I Clinical study.

The main purpose of this phase III clinical trial was to compare intra-individually the efficacy, safety and tolerability of Oleogel-S10 and non-adhesive wound dressing versus non-adhesive wound dressing only in accelerating the wound healing of Split-Thickness Skin Graft (STSG) donor sites.

Background: Trauma is a major cause of death in children and teenagers. When young patients have suffered major traumatic injuries, they require intravenous (iv) fluids to keep their blood vessels full and ensure blood flow to vital organs. Current fluid guidelines by International Trauma Committees recommend either Normal Saline (NS) or Ringer's Lactate (RL) as the fluid of choice for these patients. Although these solutions share some similarities in their composition, there are also some significant differences in sodium, chloride and lactate concentrations. Despite these differences in fluid composition, there has never been a study comparing these two fluids in paediatric trauma patients to determine which is optimal. In this study, the investigators aim to determine the optimal fluid choice for trauma resuscitation of young patients. Hypothesis: The investigators hypothesize that severely injured paediatric trauma patients resuscitated with NS will have optimal blood sodium levels compared to patients resuscitated with RL. Methods: The investigators will study 50 paediatric trauma patients that will be randomized so that half will randomly receive NS and half will receive RL as their only iv fluid for 24 hours. After 24 hours, the investigators will compare in blood the sodium level, the amount of acid, and the concentrations of inflammation molecules in relation to those whom received NS versus RL. Expected Results and Significance: Maintaining optimal levels of these biochemical markers is imperative in reducing morbidity and mortality in severely injured paediatric patients. If significant differences are present, the investigators will be able to determine which fluid is preferred and expect these data to complement current trauma resuscitation guidelines.
