About this study

Official title: The Impact of Hypoxic Conditions on Apoptosis in Polymorphonuclear Cells and Inflammatory Cytokines of Trauma Patients at Emergency Department

This study tries to find how hypoxia and hyperoxia, among types of the respiratory failure induced cell damage that can arise in the course of traumatic damage and treatment, influences apoptosis of PMN cells and IL-6 and tumor necrosis factor(TNF)-α as inflammatory cytokines.

Read the detailed description

Many patients visit an emergency room because of their trauma. Trauma patients account for around 25-35% in an emergency room. Trauma is the biggest cause of acquired disabilities, and is greatly related to death and disabilities of those aged less than 44. As such, since trauma leads to lowering personal life quality and greatly influences social and economic aspects, it is greatly dealt with in public medical service.

Primarily, patients with trauma experience a lot of bleeding and respiratory failure induced by multiple causes, and furthermore is likely to have hypovolaemic shock. Secondarily, the low blood flow induced by trauma and hypovolaemic shock triggers hypoxia and systemic inflammatory response syndrome(SIRS), and therefore lowering immunity leads to compensatory anti-inflammatory response syndrome(CARS). After that, failures to keep homeostasis, such as immune dysregulation induced acute respiratory distress syndrome (ARDS), multiple organ failure(MOF), immune function reduction, and inflammation overexpression, and other additional causes damage the patients who can end up being dead without recovery.

A trauma patient is able to be exposed to multiple complications of trauma and continue to have hypoxia and hyperoxia with multiple causes in the treatment step. Hypoxia triggers multiple organ failure by cell death and lack of oxygen, and especially is sensitive to nerve cells. Hyperoxia causes the problem of immunity system stimulation by oxygen radical and hydrogen peroxide(H2O2) secretion. As such, an oxygen condition can influence organ failure and inflammatory response in various ways. These hypoxia and hyperoxia are considered to be influential on post-trauma inflammation and on Polymorphonuclear Cells(PMN) and cytokine. A patient's oxygen condition control is the basic treatment of a trauma patient and is able to influence not only the maintenance of oxygen concentration in the body, but the immunity system for keeping body homeostasis to respond to trauma.

Therefore, it is important to know how a patient's oxygen condition influences cells in order to treat the patient. Nevertheless, there is no research on how hypoxia and hyperoxia influence PMN cell and inflammatory cytokine as inflammatory cells playing a critical role in post-trauma immunity function. Therefore, this study tries to find how hypoxia and hyperoxia, among types of the respiratory failure induced cell damage that can arise in the course of traumatic damage and treatment, influences apoptosis of PMN cells and IL-6 and tumor necrosis factor(TNF)-α as inflammatory cytokines. This study is expected to be used as a fundamental material for treating relevant patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Multiple-trauma patientsProcedure or surgery

    The blood samples of the patients who agreed on this research are obtained in order to check their inflammatory response factor, and then their medical records are checked to find their initial ABGA result, lactate, C-reactive protein(CRP) known as initial inflammatory response, and procalcitonin.

    A patient's whole blood is collected in the tube with ethylene diaminetetracetic acid (EDTA) treatment. A modified method of Boyum's technique is applied so as to separate polymorphonuclear neutrophils. The separated polymorphonuclear neutrophils is collected so as to check apoptosis. And then, in the separated plasma, interleukin(IL)-6 and tumor necrosis factor(TNF)-α are measured, and its correlation with oxygen saturation will be analyzed.
