Trauma injury is the leading cause of mortality and hospitalization worldwide and the leading cause of potential years of productive life lost. Hypercatabolism after trauma may lead to acute protein malnutrition that ultimately results in multiple organ failure. Therefore, nutritional support is an essential component of the care of critical trauma patients for optimizing outcomes. Evidence-based practice improves the quality of care through patient-centered care, the utilization of patient resources, provider resources and experiences, current research and scientific information. The main objective; of this study was to assess and evaluate the effect of evidence-based enteral nutrition (EN) protocol on complications prevention among trauma patients. The research hypothesis; evidence-based enteral nutrition protocol will prevent complications among trauma patients. The study subjects consisted of 50 adult patients diagnosed with trauma and divided equally into two groups; control group who received the routine hospital nutrition and study group who received evidence-based enteral nutrition protocol at the Intensive Care Unit (ICU) El-Minia University Hospital. The tools of data collection were; 1) Assessment sheet, it includes two parts, 1st part included socio-demographic data of the patient. 2nd part included five items that cover medical data, 2) Evidence-based enteral nutrition protocol, and 3) Evaluation sheet, it includes two parts, 1st part included the laboratory investigations. 2nd part covers the vital signs. Results: This study revealed that the majority of the control group less than thirty years old compared to study group equal or more than forty years old. There are statistically significant differences regarding mouth condition, severe infection, and nutritional assessment, among study and control groups. The result also revealed that the highest percent regarding the time of start enteral feeding and body positioning were among the study group. Conclusion: Evidence-based enteral nutrition protocol had significantly prevention of complications among trauma patients. Recommendation: Hospital should be following evidence-based enteral nutrition protocol to prevent complications among trauma patients at intensive care unit.

Background: Acid-base disorders are very common in critically ill as well as contribute significantly to morbidity and mortality. Aim: To evaluate the effect of acid-base disorders on mortality and level of consciousness for patients admitted to ICU. Design: descriptive exploratory research design was utilized to conduct this study .Setting: This study was carried out in anesthesia intensive care units at Assiut university hospital. Sample: One hundred sixty adult male and female patients. Tools: Two tools were used in this study, the Critically Ill Patients Characteristics tool, and Acid-base parameters assessment tool. Result: more than one third of the patients (36.3%) had respiratory alkalosis and was the most common acid-base disorder observed on admission . Metabolic acidosis and respiratory acidosis was associated with higher mortality (36.4%), and (22.75). Length of ICU stay was significantly higher in non-survivors (10.23±6.91 versus 7.60±4.69, p= 0.007). Mortality was significantly higher in the GCS < 9 group with metabolic acidosis (37.5 % versus 33.3 %, p=0.033). Conclusion: Respiratory alkalosis was a common acid base disorder. Acidemia whether due to metabolic or respiratory acidosis is associated with increased mortality in ICU patients. Low GCS low is associated with increased mortality especially in the patients with metabolic acidosis. Recommendation: Closely monitoring and early managment is important to correct acid-base imbalance to avoid poor patient outcomes.
