Ultrasound-assisted catheter directed thrombolysis (US-CDT) is frequently used for the treatment of pulmonary embolism. Due to the variety of thrombolytic and anticoagulant dosing utilized in practice, patients with pulmonary embolism who undergo US-CDT may be at an increased risk of bleeding. The primary objective of this study was to determine factors associated with major bleeding occurring with US-CDT. Secondary outcomes included in-hospital mortality and ventilator-free days. This multicentre retrospective cohort study evaluated inpatients diagnosed with pulmonary embolism and treated with US-CDT and systemic anticoagulation. A total of 173 patients were included. Most patients receiving US-CDT had a submassive pulmonary embolism with a median Pulmonary Embolism Severity Index (PESI) score of 85. Major bleeding events occurred in 37 of the 173 patients (21%). In-hospital mortality occurred in four (11%) of the patients who experienced major bleeding and three (2%) patients who did not experience major bleeding (P = 0.04). Factors associated with a higher risk of major bleeding included female sex and anticoagulation strategy. The odds of major bleeding were 3.3 times higher for women than for men (odds ratio = 3.32, 95% confidence interval 1.29-8.54). In addition, for each second increase in goal aPTT the odds of major bleeding increased by 5% (odds ratio = 1.05, 95% confidence interval 1.02-1.09). In patients with pulmonary embolism treated with US-CDT, major bleeding may be underestimated. In this analysis, major bleeding was associated with female sex and higher goal aPTT levels. In addition, bleeding with US-CDT was associated with a higher risk of in-hospital mortality.

Background Paroxysmal sympathetic hyperactivity, which affects up to 10% of all acquired brain injury survivors, is characterized by elevated heart rate, blood pressure, respiratory rate, and temperature; diaphoresis; and increased posturing. Pharmacological agents that have been studied in the management of this disorder include opiates, γ-aminobutyric acid agents, dopaminergic agents, and β blockers. Although paroxysmal sympathetic hyperactivity is a relatively common complication after acquired brain injury, there is a paucity of recommendations or comparisons of agents for the management of this disorder. Objective To evaluate all relevant literature on pharmacological therapies used to manage patients with paroxysmal sympathetic hyperactivity to help elucidate possible best practices. Methods Of the 27 studies evaluated for inclusion, 10 studies received full review: 4 retrospective cohort studies, 5 single case studies, and 1 case series. Results Monotherapy is usually not effective in the management of paroxysmal sympathetic hyperactivity and multiple agents with different mechanisms of action should be considered. α2-Agonists such as dexmedetomidine may hold some slight clinical efficacy over agents like propofol, and with respect to oral medications, propranolol might convey some slight advantage compared to others. However, with the limited data available, these results must be interpreted with caution. Conclusions As the treatment of paroxysmal sympathetic hyperactivity is reactive to symptomatic evolution over time, critical care nurses play a vital role in the monitoring and treatment of these patients. Limited data exist on the management of paroxysmal sympathetic hyperactivity and larger robust data sets are needed to guide decision-making. (Critical Care Nurse. 2020;40[3]:e9-e16)

Background There is significant data in the medical and surgical literature supporting the correlations between positive volume balance and negative outcomes such as AKI, prolonged mechanical ventilation, intensive care unit and hospital length of stay and increased mortality. Methods This single-center, retrospective chart review included adult patients identified from a Trauma Registry database. The primary outcome was the total ICU LOS. Secondary outcomes include hospital LOS, ventilator-free days, incidence of compartment syndrome, acute respiratory distress syndrome (ARDS), renal replacement therapy (RRT), and days of vasopressor therapy. Results In general, baseline characteristics were similar between groups with the exception of mechanism of injury, FAST exam, and disposition from the ED. The ICU LOS was shortest in the negative fluid balance and longest in the positive fluid balance group (4 days vs 6 days, P = .001). Hospital LOS was also shorter in the negative balance group than that of the positive balance group (7 days vs 12 days, P < .001). More patients in the positive balance group experienced acute respiratory distress syndrome compared to the negative balance group (6.3% vs 0%, P = .004). There was no significant difference in the incidence of renal replacement therapy, days of vasopressor therapy, or ventilator-free days. Discussion A negative fluid balance at seventy-two hours was associated with a shorter ICU and hospital LOS in critically ill trauma patients. Our observed correlation between positive volume balance and total ICU days merits further exploration with prospective, comparative studies of lower volume resuscitation to key physiologic endpoints compared with routine standard of care.

BACKGROUND Sepsis is associated with high rates of in-hospital mortality, despite being the focus of medical research and public health initiatives for several years. The primary objective of this study was to determine the influence of septic phenotypes on rates of in-hospital mortality throughout ICU admission. MATERIALS AND METHODS Retrospective, single center cohort study. Medical ICU of an academic medical center. Medical ICU patients admitted between January 2016 and August 2019 with a "sepsis alert" were screened for admitting diagnosis of "sepsis" or "septic shock." Patients were classified into one of four clinical sepsis phenotypes: multi-organ failure (MOF), respiratory dysfunction (RD), neurologic dysfunction (ND), or other patients (OP). RESULTS An analysis of 320 patients was completed. In-hospital mortality was different between groups (p
