Multicenter Retrospective Review of Ketamine Use in Pediatric Intensive Care Units (Ketamine-PICU Study).

Objective: Describe continuous infusion (CI) ketamine practices in pediatric intensive care units (PICUs) and evaluate its effect on pain/sedation scores, exposure to analgesics/sedatives, and adverse effects (AEs).

Methods: Multicenter, retrospective, observational study in children <18 years who received CI ketamine between 2014 and 2017. Time spent in goal pain/sedation score range and daily cumulative doses of analgesics/sedatives were compared from the 24 hours (H) prior to CI ketamine to the first 24H and 25-48H of the CI.

Out-of-Hospital Intranasal Ketamine as an Adjunct to Fentanyl for the Treatment of Acute Traumatic Pain: A Randomized Clinical Trial.

Study Objective: To evaluate if out-of-hospital administration of fentanyl and intranasal ketamine, compared to fentanyl alone, improves early pain control after injury.

Methods: We conducted an out-of-hospital randomized, placebo-controlled, blinded, parallel group clinical trial from October 2017 to December 2021. Participants were male, aged 18 to 65 years, receiving fentanyl to treat acute traumatic pain prior to hospital arrival, treated by an urban fire-based emergency medical services agency, and transported to the region's only adult Level I trauma center.

Pharmacokinetics of Levetiracetam Seizure Prophylaxis in Severe Traumatic Brain Injury.

Background: Drug pharmacokinetics (PK) are altered in neurocritically ill patients, and optimal levetiracetam dosing for seizure prophylaxis is unknown.

Objective: This study evaluates levetiracetam PK in critically ill patients with severe traumatic brain injury (sTBI) receiving intravenous levetiracetam 1000 mg every 8 (LEV8) to 12 (LEV12) hours for seizure prophylaxis.

Methods: This prospective, open-label study was conducted at a level 1 trauma, academic, quaternary care center.

Antibiotic Duration Following Abdominal Gunshot Injuries With Associated Pelvis or Spine Involvement: A 20-Year Single-Center Experience.

Introduction: Optimal antimicrobial prophylaxis duration following gunshot wounds (GSW) to the abdomen with an associated orthopedic fracture is unknown. This study evaluated the safety and efficacy of short versus long courses of prophylactic antibiotics following penetrating hollow viscus injury with communicating orthopedic fracture.

Methods: This retrospective study included adult patients admitted to the trauma service over a 20-y period who sustained an abdominal GSW with hollow viscus injury and communicating spine or pelvic fractures.

Evaluating the Utility of High Sensitivity Troponin in Blunt Cardiac Injury.

Introduction: Screening for blunt cardiac injury (BCI) includes obtaining a serum troponin level and an electrocardiogram for patients diagnosed with a sternal fracture. Our institution has transitioned to the use of a high sensitivity troponin I (hsTnI). The aim of this study was to determine whether hsTnI is comparable to troponin I (TnI) in identifying clinically significant BCI.

Reversal of apixaban and rivaroxaban with andexanet alfa prior to invasive or surgical procedures.

Background: Outcomes following andexanet alfa reversal of factor Xa inhibitors in patients requiring urgent or emergent invasive procedures are lacking. This study aimed to describe efficacy and safety outcomes following andexanet alfa administration within 24 h of an invasive procedure.

Methods: This single-center, observational, retrospective study included patients who received andexanet alfa within 24 h of an invasive or surgical procedure.

The Association of Norepinephrine Utilization With Mortality Risk in Trauma Patients.

Introduction: While the pillars of trauma resuscitation are surgical hemostasis and blood product administration, norepinephrine (NE) can be used as an adjunct. The goal of this study was to evaluate the relationship between the maximum dose of NE, timing of NE administration, and mortality in trauma patients.

Methods: Patients admitted between January 2013 and January 2021 treated with NE were reviewed.

Tracheostomy decreases continuous analgesia and sedation requirements.

Background: The goals of sedation in the critically ill surgical patient are to minimize pain, anxiety, and agitation without hindering cardiopulmonary function. One potential benefit of tracheostomy during endotracheal intubation is the reduction of sedation and analgesia; however, there are little data to support this supposition. We hypothesized that patients undergoing tracheostomy would have a rapid reduction in sedation and analgesia following tracheostomy.

Multicenter Retrospective Review of Ketamine Use in the ICU.

Unlabelled: The response of ICU patients to continuously infused ketamine when it is used for analgesia and/or sedation remains poorly established.

Objectives: To describe continuous infusion (CI) ketamine use in critically ill patients, including indications, dose and duration, adverse effects, patient outcomes, time in goal pain/sedation score range, exposure to analgesics/sedatives, and delirium.

Design Setting And Participants: Multicenter, retrospective, observational study from twenty-five diverse institutions in the United States.

Retrospective Evaluation of Intrapleural Tissue Plasminogen Activator With or Without Dornase Alfa for the Treatment of Traumatic Retained Hemothorax: A 6-Year Experience.

Background: Intrapleural fibrinolytic instillation is second-line treatment for retained hemothorax. Dornase alfa (DNase) has demonstrated efficacy in parapneumonic effusion, but the lack of deoxyribonucleoproteins limits direct extrapolation to traumatic retained hemothorax treatment.

Objective: This study evaluated the effectiveness of intrapleural tissue plasminogen activator (tPA) with and without DNase in the treatment of retained traumatic hemothorax.

Assessment of Detectable Serum Tobramycin Concentrations in Patients Receiving Inhaled Tobramycin for Ventilator-Associated Pneumonia.

Background: Inhaled tobramycin can be used for empiric or definitive therapy of ventilator-associated pneumonia (VAP) in mechanically ventilated patients. This is believed to minimize systemic exposure and potential adverse drug toxicities including acute kidney injury (AKI). However, detectable serum tobramycin concentrations have been reported after inhaled tobramycin therapy with AKI.

Intercostal liposomal bupivacaine injection for rib fractures: A prospective randomized controlled trial.

Background: Blunt chest wall injury accounts for 15% of trauma admissions. Previous studies have shown that the number of rib fractures predicts inpatient opioid requirements, raising concerns for pharmacologic consequences, including hypotension, delirium, and opioid dependence. We hypothesized that intercostal injection of liposomal bupivacaine would reduce analgesia needs and improve spirometry metrics in trauma patients with rib fractures.

Comparison of Ceftriaxone and Antipseudomonal β-Lactam Antibiotics Utilized for Potential AmpC β-Lactamase-Producing Organisms.

Induction of antibiotic resistance is associated with increased morbidity and mortality in AmpC β-lactamase producing Enterobacteriaceae. The use of ceftriaxone is controversial for treatment of these organisms due to concerns for inducible resistance. This study was designed to compare treatment failure rates between ceftriaxone and antipseudomonal β-lactam antibiotics when used as definitive therapy for organisms most commonly associated with chromosomal AmpC β-lactamase production.

Applying Cefepime Population Pharmacokinetics to Critically Ill Patients Receiving Continuous Renal Replacement Therapy.

Patients admitted to the intensive care unit (ICU) may need continuous renal replacement therapy (CRRT) due to acute kidney injury or worsening of underlying chronic kidney disease. This will affect their antimicrobial exposure and may have a significant impact on the treatment. We aim to develop a cefepime pharmacokinetic (PK) model in CRRT ICU patients and generate the posterior predictions for a group and assess their therapy outcomes.

Clinical Experience, Characteristics, and Performance of an Acetaminophen Absorption Test in Critically Ill Patients.

Background: Altered drug and nutrient absorption presents a unique challenge in critically ill patients. Performing an acetaminophen absorption test (AAT) has been used as a marker for gastric motility and upper small bowel absorption; thus, it may provide objective data regarding enteral absorptive ability in critically ill patients.

Study Question: What is the clinical experience with AAT when used as a surrogate marker for enteral absorption in critically ill patients?

Study Design: This single-center, retrospective, cohort study evaluated serum acetaminophen concentrations within 180 minutes following 1-time enteral administration of an AAT.

Ketamine Stability over Six Months of Exposure to Moderate and High Temperature Environments.

All medications should be stored within temperature ranges defined by manufacturers, but logistical and operational challenges of prehospital and military settings complicate adherence to these recommendations. Lorazepam and succinylcholine experience clinically relevant heat-related degradation, whereas midazolam does not. Because ketamine's stability when stored outside manufacturer recommendations is unknown, we evaluated the heat-related degradation of ketamine exposed to several temperature ranges.

Impact of antithrombin III and enoxaparin dosage adjustment on prophylactic anti-Xa concentrations in trauma patients at high risk for venous thromboembolism: a randomized pilot trial.

The impact of antithrombin III activity (AT-III) on prophylactic enoxaparin anti-factor Xa concentration (anti-Xa) is unknown in high-risk trauma patients. So too is the optimal anti-Xa-adjusted enoxaparin dosage. This prospective, randomized, pilot study sought to explore the association between AT-III and anti-Xa goal attainment and to preliminarily evaluate two enoxaparin dosage adjustment strategies in patients with subprophylactic anti-Xa.

Hitting the Vasopressor Ceiling: Finding Norepinephrine Associated Mortality in the Critically Ill.

Background: There is no consensus on what dose of norepinephrine corresponds with futility. The purpose of this study was to investigate the maximum infusion and cumulative doses of norepinephrine associated with survival for patients in medical and surgical intensive care units (MICU and SICU).

Materials And Methods: A retrospective review was conducted of 661 critically ill patients admitted to a large academic medical center who received norepinephrine.

Impact of Weight on Anti-Xa Attainment in High-Risk Trauma Patients on Enoxaparin Chemoprophylaxis.

Background: Serum anti-factor Xa (anti-Xa) concentration may guide low molecular weight heparin chemoprophylaxis in trauma patients. Higher total body weight (TBW) is a risk factor for subprophylactic anti-Xa and venous thromboembolism (VTE). The purpose of this study was to evaluate TBW differences in patients with subprophylactic versus prophylactic trough anti-Xa.

Cefepime Population Pharmacokinetics and Target Attainment in Critically Ill Patients on Continuous Renal Replacement Therapy.

Sepsis causes half of acute kidney injuries in the intensive care unit (ICU). ICU patients may need continuous renal replacement therapy (CRRT), which will affect their antimicrobial exposure. We aimed to build a cefepime population pharmacokinetic (PK) model in CRRT ICU patients and perform simulations to assess target attainment.

Admission thrombelastography does not guide dose adjustment of enoxaparin in trauma patients.

Background: Enoxaparin is used as chemoprophylaxis to reduce incidence of venous thromboembolism and its complications following trauma. Serum anti-Xa monitoring is used to assess efficacy but requires several doses to be administered. Thrombelastography assesses hypercoagulability and may have utility identifying high-risk patients for venous thromboembolism.

Analgesia and Sedation Strategies in Mechanically Ventilated Adults with COVID-19.

Evidence-based management of analgesia and sedation in COVID-19-associated acute respiratory distress syndrome remains limited. Non-guideline recommended analgesic and sedative medication regimens and deeper sedation targets have been employed for patients with COVID-19 due to exaggerated analgesia and sedation requirements with extended durations of mechanical ventilation. This, coupled with a desire to minimize nurse entry into COVID-19 patient rooms, marked obesity, altered end-organ function, and evolving medication shortages, presents numerous short- and long-term challenges.

Food and Drug Administration and Institutional Review Board Approval of a Novel Prehospital Informed Consent Process for Emergency Research.

Research on the management of acute pain in the prehospital setting is fraught with challenges. The prehospital setting is complex due to constrained time, resources, and training. Research activities must not interfere with the underlying clinical priorities of immediate patient stabilization and rapid transport to an appropriate hospital.

Intranasal Ketamine as an Adjunct to Fentanyl for the Prehospital Treatment of Acute Traumatic Pain: Design and Rationale of a Randomized Controlled Trial.

: Acute pain management is fundamental in prehospital trauma care. Early pain control may decrease the risk of developing post-traumatic stress disorder (PTSD) and chronic pain. Fentanyl and ketamine are frequently used off-label, but there is a paucity of comparative data to guide decision-making about treatment of prehospital severe, acute pain.
