RESUMO
Traumatic brain injuries (TBIs) represent a significant public health concern, with mild-to-moderate cases comprising a substantial portion of incidents. Understanding the predictors of mortality among adult patients with mild-to-moderate TBIs is crucial for optimizing clinical management and improving outcomes. This literature review examines the existing research to identify and analyze the mortality predictors in this patient population. Through a comprehensive review of peer-reviewed articles and clinical studies, key prognostic factors, such as age, Glasgow Coma Scale (GCS) score, the presence of intracranial hemorrhage, pupillary reactivity, and coexisting medical conditions, are explored. Additionally, this review investigates the role of advanced imaging modalities, biomarkers, and scoring systems in predicting mortality following a mild-to-moderate TBI. By synthesizing the findings from diverse studies, this review aims to provide clinicians and researchers with valuable insights into the factors influencing mortality outcomes in adult patients with a mild-to-moderate TBI, thus facilitating more informed decision making and targeted interventions in clinical practice.
RESUMO
Sepsis, the most serious complication of infection, occurs when a cascade of potentially life-threatening inflammatory responses is triggered. Potentially life-threatening septic shock is a complication of sepsis that occurs when hemodynamic instability occurs. Septic shock may cause organ failure, most commonly involving the kidneys. The pathophysiology and hemodynamic mechanisms of acute kidney injury in the case of sepsis or septic shock remain to be elucidated, but previous studies have suggested multiple possible mechanisms or the interplay of multiple mechanisms. Norepinephrine is used as the first-line vasopressor in the management of septic shock. Studies have reported different hemodynamic effects of norepinephrine on renal circulation, with some suggesting that it could possibly exacerbate acute kidney injury caused by septic shock. This narrative review briefly covers the updates on sepsis and septic shock regarding definitions, statistics, diagnosis, and management, with an explanation of the putative pathophysiological mechanisms and hemodynamic changes, as well as updated evidence. Sepsis-associated acute kidney injury remains a major burden on the healthcare system. This review aims to improve the real-world clinical understanding of the possible adverse outcomes of norepinephrine use in sepsis-associated acute kidney injury.
RESUMO
Introduction: Morbid obesity is one of the major concerns when performing surgeries, due to higher risks of anesthetic complications. Combined spinal and epidural (CSE) anesthesia technique is used effectively in variety of surgical procedures. Case presentation: Our patient is a 58-year old female with a Body Mass Index (BMI) of 44.53 who presented to the emergency department complaining of an abdominal pain of a renal nature. She was found to have an abdominal mass suggestive of anexial mass or a Gastro Intestinal Stromal Tumor (GIST) and was scheduled for surgery. Due to the risks associated with general anesthesia, a double neuraxial catheter (subarachnoid and epidural) was the anesthitic method of choice. Discussion: Overweight and obesity represent a rapidly growing threat to the health of populations in an increasing number of countries. The first report using the double catheter technique described a parturient with a BMI of 76 kg/m2 who had a lumbar Combined Spinal Epidural (CSE) catheter placed for intraoperative anesthesia and postoperative pain management. In the published literature CSE technique use is limited to obstetric procedure of obese females. Conclusion: In our case it is highlighted how an obese patient, with severe comorbidities that can jeopardize the success of the treatments, can be discharged in a few days by performing an "unconventional" but effective anesthetic technique.
