A Single Hospital-Wide Antibiogram is Insufficient to Account for Differences in Antibiotic Resistance Patterns Across Multiple ICUs.

Background: Infection is a common cause of mortality within intensive care units (ICUs). Antibiotic resistance patterns and culture data are used to create antibiograms. Knowledge of antibiograms facilitates guiding empiric therapies and reduces mortality.

Monotherapy Antibiotic Prophylaxis of Lower Extremity Long Bone Type III Open Fractures.

Gustilo type III open fractures involve extensive soft tissue damage and wound contamination that pose significant infection risks. The historical standard for antibiotic prophylaxis has been cefazolin and gentamicin. We conducted a retrospective cohort study of lower extremity type III open fractures treated with ceftriaxone alone for prophylaxis.

Patient Resiliency and Caregiver Burden After Traumatic Spinal Cord Injury Resulting in Quadriplegia.

Traumatic spinal cord injury (tSCI) resulting in quadriplegia is a life-altering injury for patients and caregivers. We conducted a retrospective review of patients treated for tSCI and quadriplegia at a level 1 trauma center to assess quality of life (QOL), socioeconomic factors, and mortality. Patients and caregivers were surveyed.

Admission Medication Reconciliation Discrepancies in Trauma Patients: Consistent Nursing Care May Not Be the Answer.

Inadvertent medication reconciliation discrepancies are common among trauma patient populations. We conducted a prospective study at a level 1 trauma center to assess incidence of inadvertent medication reconciliation discrepancies following decreased reliance on short-term nursing staff. Patients and independent sources were interviewed for home medication lists and compared to admission medication reconciliation (AMR) lists.

Deleterious effects of plasma-derived cellular debris in a porcine model of hemorrhagic shock.

Background: Recent studies identify large quantities of inflammatory cellular debris within Fresh Frozen Plasma (FFP). As FFP is a mainstay of hemorrhagic shock resuscitation, we used a porcine model of hemorrhagic shock and ischemia/reperfusion to investigate the inflammatory potential of plasma-derived cellular debris administered during resuscitation.

Methods: The porcine model of hemorrhagic shock included laparotomy with 35 % hemorrhage (Hem), 45 min of ischemia from supraceliac aortic occlusion with subsequent clamp release (IR), followed by protocolized resuscitation for 6 h.

Treatment of Chronic Hypertrophic Burn Scars With a Fractional CO 2 Laser Is Well Tolerated in an Outpatient Clinic Setting.

Introduction: The necessity of treating hypertrophic burn scars has expanded significantly with increased burn survivorship. Ablative lasers, such as carbon dioxide (CO 2 ) lasers, have been the most common nonoperative option for improving functional outcomes in severe recalcitrant hypertrophic burn scars. However, the overwhelming majority of ablative lasers used for this indication require a combination of systemic analgesia, sedation, and/or general anesthesia due to the painful nature of the procedure.

Incidence and Outcomes of Undiagnosed and Untreated Diabetes Mellitus in Trauma Patients.

Diabetes is a major determinate for mortality in trauma patients. Many diabetics are undiagnosed or poorly controlled. Trauma patients disproportionately come from lower socioeconomic status, making missed diagnoses more likely.

Defining Pathogen and Susceptibility Patterns for Early Versus Late Ventilator Associated Pneumonia in Trauma Patients to Guide Empiric Treatment Decisions.

Introduction: Studies have demonstrated that trauma patients with early-ventilator associated pneumonia (early-VAP, < 7 days) have decreased risk of methicillin-resistant (MRSA) and infections. We hypothesize that routinely using broad-spectrum antibiotics is unnecessary to treat trauma patients with the diagnosis of early-VAP.

Methods: This retrospective cohort study included adult trauma patients with the diagnosis of VAP.

Cryoablation for Chest Wall Trauma: A Brief Report.

Respiratory failure secondary to rib fractures is a major source of morbidity and mortality in trauma patients, particularly in older populations. Management of pain in these patients is complex due to the nature of the injuries. We present 3 patients who underwent a video-assisted thoracoscopic cryoablation of intercostal nerves for pain control after chest trauma.

The Relationship between Serum Sodium, Serum Osmolality, and Intracranial Pressure in Patients with Traumatic Brain Injury Treated with Hyperosmolar Therapy.

Background: Treatment of elevated intracranial pressure (ICP) in traumatic brain injury (TBI) is controversial. Hyperosmolar therapy is used to prevent cerebral edema in these patients. Many intensivists measure direct correlates of these agents-serum sodium and osmolality.

The Treatment of Rib Fractures : A Single-Center Comparison.

Background: Rib fractures are a major problem characterized by pain, increased length of stay, and respiratory complications. Treatments include fixation, management with opiates, paraspinous local anesthetic pumps, and intercostal nerve blocks. The aim of this study was to evaluate the use of treatment options and compare clinically relevant outcomes.

Potential contribution of mitochondrial DNA damage associated molecular patterns in transfusion products to the development of acute respiratory distress syndrome after multiple transfusions.

Background: Massive transfusions are accompanied by an increased incidence of a particularly aggressive and lethal form of acute lung injury (delayed transfusion-related acute lung injury) which occurs longer than 24 hours after transfusions. In light of recent reports showing that mitochondrial (mt)DNA damage-associated molecular patterns (DAMPs) are potent proinflammatory mediators, and that their abundance in the sera of severely injured or septic patients is predictive of clinical outcomes, we explored the idea that mtDNA DAMPs are present in transfusion products and are associated with the occurrence of delayed transfusion-related acute lung injury.

Methods: We prospectively enrolled fourteen consecutive severely injured patients that received greater than three units of blood transfusion products and determined if the total amount of mtDNA DAMPs delivered during transfusion correlated with serum mtDNA DAMPs measured after the last transfusion, and whether the quantity of mtDNA DAMPs in the serum-predicted development of acute respiratory distress syndrome (ARDS).

Mitochondrial DNA damage associated molecular patterns in ventilator-associated pneumonia: Prevention and reversal by intratracheal DNase I.

Background: Previous studies in isolated perfused rat lungs have revealed that endothelial barrier disruption after intratracheal administration of Pseudomonas aeruginosa (strain 103; PA103) only occurs after accumulation of extracellular mitochondrial DNA (mtDNA) damage-associated molecular patterns (DAMPs) in the perfusate and is suppressed by addition of DNase to the perfusion medium. Herein, we tested the hypothesis that intratracheal DNase-a route of administration readily translatable to patient with ventilator-associated pneumonia (VAP)-also enhances degradation of mtDNA and prevents bacteria-induced lung injury.

Methods: Intratracheal DNase was administered to isolated rat lungs either before or after intratracheal challenge with PA103 to determine if bacteria-induced mtDNA DAMP-dependent lung injury could be prevented or reversed by enhanced mtDNA degradation.

The Combination of SAT and SBT Protocols May Help Reduce the Incidence of Ventilator-Associated Pneumonia in the Burn Intensive Care Unit.

There are few published reports on the unique nature of burn patients using a paired spontaneous awakening and spontaneous breathing protocol. A combined protocol was implemented in our burn intensive care unit (ICU) on January 1, 2012. This study evaluates the impact of this protocol on patient outcomes in a burn ICU.

Evaluation of Microvascular Perfusion and Resuscitation after Severe Injury.

Achieving adequate perfusion is a key goal of treatment in severe trauma; however, tissue perfusion has classically been measured by indirect means. Direct visualization of capillary flow has been applied in sepsis, but application of this technology to the trauma population has been limited. The purpose of this investigation was to compare the efficacy of standard indirect measures of perfusion to direct imaging of the sublingual microcirculatory flow during trauma resuscitation.
