Background and importance: Effective and safe procedural sedation is pivotal for the quality of care in the emergency department (ED).

Objectives: The aim of this work is to evaluate the feasibility, effectiveness, and safety procedural sedation performed by emergency physicians in the ED setting in Italy.

Design/setting and participants/intervention: Following a specific training of the staff and with the adoption of a standardized protocol, a registry of procedural sedations performed on adult patients in 10 Italian EDs was compiled from 2019 to 2022; the following basic data were recorded: demographic and clinical information, procedure's indication, administered drugs, predefined, and actual sedation level.

Outcome measures and analysis: Effectiveness was evaluated considering three parameters: successful completion of the procedure, absence of procedural pain, and no memory of the procedure; adverse events were classified according to the World Society of Intravenous Anaesthesia criteria and evaluated taking into account clinical and procedural variables.

Main results: The study included 1349 patients (median age 68 years, male 64%). Sedation was performed for electrical cardioversion (66.3%), orthopedic procedures (23.2%), or other procedures (10.5%). Propofol (67%) and midazolam (24.2%) were the two most frequently used sedatives and 70.6% of the patients achieved a deep level of sedation.Procedural failure occurred in 4.6% of cases, with no significant differences between procedure types or drugs used. Recall of the procedure and procedural related pain were reported by 2.9% and 2.6% of patients, respectively, and were more frequently related to orthopedic procedures, midazolam use - if compared with propofol, and lower levels of sedation.A total of 135 adverse events were observed, with an overall incidence of 10%: 38 minimal adverse events (2.8%), 38 minor adverse events (2.8%), and 59 moderate adverse events (4.4%). There were no adverse events requiring unplanned hospital admission or escalation of care, and no sentinel adverse events were observed. All adverse events were resolved with simple and noninvasive treatments. The incidence of adverse events was greater with higher American Society of Anesthesiologists class, intermediate/difficult airway, and deeper sedation levels.

Conclusion: Procedural sedation performed in Italian EDs by emergency physicians, with propofol as main sedative, was effective and safe, and has comparable adverse event rates with previous international studies.

Background: Noncompressible truncal hemorrhage is a major contributor to preventable deaths in trauma patients and, despite advances in emergency care, still poses a big challenge.

Objectives: This study aimed to assess the clinical efficacy of trauma resuscitation care incorporating Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) compared to standard care for managing uncontrolled torso or lower body hemorrhage.

Methods: This study utilized a target trial design with a matched case-control methodology, emulating randomized 1 : 1 allocation for patients receiving trauma resuscitation care with or without the use of REBOA. The study was conducted at a high-volume trauma center in Southern Austria, including trauma patients treated between January 2019 and October 2023, aged 16 and above, with suspected severe non-compressible torso hemorrhage. The primary outcome was 30-day in-hospital mortality. Secondary outcomes were in-hospital mortality rates at 3, 6, 24 h, and 90 days, need for damage control procedures, time to these procedures, computed tomography (CT) scan rates during resuscitation, complications, length of intensive care and in-hospital stay, and causes of death.

Results: Median age was 55 [interquartile range (IQR) 42-64] years. Median total injury severity, assessed by Injury Severity Score, was 46.5 (IQR: 43-57). There was no significant difference in 30-day in-hospital mortality between groups [9/22 (41%) vs. 9/22 (41%), odds ratio: 1.00, 95% confidence interval (CI): 0.3-3.36, P  > 0.999]. Lower mortality rates within 3, 6, and 24 h were observed in the REBOA group; in a Cox proportional hazards model, hazard ratio (95% CI) for mortality in the REBOA group was 0.87 (0.35-2.15). Timing to damage control procedures did not significantly differ between groups, although patients in the REBOA group underwent significantly more CT scans. Bleeding was cited as the main cause of death less frequently in the REBOA group.

Conclusion: In severely injured patients presenting with possible major non-compressible torso hemorrhage, a systematically implemented resuscitation strategy including REBOA during the initial hospital phase, is not associated with significant changes in mortality.

Background and importance: Elderly patients often have atypical clinical presentations. Lactate measurement on arrival at the Emergency Department (ED) could be useful to identify elderly patients with a bad prognosis.

Objective: The study aimed to investigate the relationship between serum lactate determined at ED arrival and the probability of inhospital mortality and intensive care (ICU) admission in elderly patients.

Design: Retrospective multipurpose registry. Secondary analysis of the EDEN cohort (Elderly Department and Elder Needs).

Settings and participants: All patients ≥65 years attending 52 Spanish EDs during 2 week and in whom serum lactate was determined at ED arrival.

Outcome measures and analysis: The relationship between serum lactate values and the risk of inhospital all-cause death and transfer from the ED to the ICU was assessed by unadjusted and adjusted logistic regression assuming linearity and restricted cubic spline models assuming nonlinearity.

Results: The cohort included 25 557 patients. The 3024 patients in whom lactate was measured were analyzed. The median age was 81 years (74-87), 1506 (27.2%) were women, 591 (19.5%) had serious comorbidities, 475 (15.7%) severe dependency, and 648 (21.4%) dementia. Death occurred during hospitalization in 217 patients (7.2%) and 53 patients (1.75%) were admitted to the ICU. Serum lactate values were nonlinear related to inhospital mortality and ICU admission. Serum lactate >3.1 mmol/L [odds ratio (OR): 1.60, 95% confidence interval (CI): 1.02-2.50] for inhospital mortality and 3.2 mmol/L (OR: 2.83, 95% CI: 1.03-6.79) for ICU admission were associated with significantly increased ORs in the adjusted models.

Conclusion: Serum lactate measured at ED arrival has a significant and exponential relationship with inhospital mortality and ICU admission in elderly patients.
