UNASSIGNED: Acute heart failure necessitates intensive care, and arterial catheterization is a commonly performed invasive procedure in the intensive care unit (ICU). We aimed to investigate the association between arterial catheterization and outcomes in acute heart failure patients without shock.
UNASSIGNED: We utilized MIMIC-IV database records for acute heart failure patients at Beth Israel Deaconess Medical Center from 2008 to 2019. Employing doubly robust estimation, we examined the relationship between arterial catheterization and outcomes, including 28-day, 90-day, in-hospital mortality, and ICU-free days within 28 days.
UNASSIGNED: Of 6936 patients identified, 2078 met inclusion criteria; 347 underwent arterial catheterization during their ICU stay. We observed no significant difference in 28-day mortality (odds ratio [OR]: 0.61, 95 % confidence interval [CI]: 0.31-1.21, P = 0.155), though catheterization was associated with reduced in-hospital mortality (OR: 0.41, 95 % CI: 0.14-0.65, P = 0.02). No significant effects were observed on 90-day mortality or ICU-free days within 28 days.
UNASSIGNED: Our findings suggest that arterial catheterization is not associated with 28- and 90-day mortality rates in acute heart failure patients without shock but is linked to lower in-hospital mortality. Additional research and consensus are required to determine the appropriate utilization of arterial catheterization in patients.

We conducted a meta-analysis to assess the diagnostic performance of chest ultrasound compared with a pericardial window for the detection of occult penetrating cardiac wounds in patients with penetrating thoracic trauma who were hemodynamically stable. A systematic literature search up to December 2022 was performed and 567 related studies were evaluated. The chosen studies comprised 629 penetrating thoracic trauma subjects who participated in the selected studies\' baseline. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of different chest ultrasounds on wound infection after penetrating thoracic trauma by the dichotomous methods with a random or fixed effect model. The chest ultrasound resulted in significantly lower occult penetrating cardiac wounds detection (OR, 0.02; 95% CI, 0.01-0.08, P < 0.001), higher false positive (OR, 33.85; 95% CI, 9.21-124.39, P < 0.001), and higher false negative (OR, 27.31; 95% CI, 7.62-97.86, P < 0.001) compared with the pericardial window in penetrating thoracic trauma. The chest ultrasound resulted in significantly lower occult penetrating cardiac wound detection, higher false positives, and higher false negatives compared with the pericardial window in penetrating thoracic trauma. Although care should be taken when dealing with the results because all of the studies had less than 200 subjects as a sample size.

This study was undertaken to determine the most hemodynamically stable method to low-flow anesthesia (LFA) between 10-minute administration of high fresh gas flow, 0.8 equilibration ratio (Fe/Fi), and state entropy (SE) between 40 and 60, a marker for adequate depth of anesthesia. Change from high fresh gas flow to LFA was done in 3 groups of 30 patients each: group T (time): 10 minutes; group R (ratio): Fe/Fi = 0.8, and group SE: SE = 40 to 50. A decrease in mean blood pressure or heart rate was treated with ephedrine or atropine, with study termination at more than 2 boluses of either. In group SE, no patient required ephedrine or atropine. The requirement for ephedrine was statistically higher in groups R and T than group SE. Atropine requirement was statistically higher in group R vs groups T and SE. In group R, the mean (SD) time to LFA was 43.9 (20.37) minutes, and in group SE was 151.9 (74.4) seconds. Hypotension or bradycardia did not occur when LFA was started at SE of 40 to 50 after anesthesia induction compared with LFA at 10 minutes, which caused hypotension, and Fe/Fi of 0.8, which caused hypotension and bradycardia.

Laparoscopy is being increasingly applied as either a diagnostic or therapeutic intervention in the management of abdominal trauma. However, its outcomes in comparison with conventional laparotomy remain unclear, especially in terms of therapeutic management.
This retrospective cohort study included patients from three trauma centers in Beijing, China. Fifty-four patients undergoing laparoscopic interventions for abdominal trauma by experienced laparoscopists were enrolled in the laparoscopy group (LP group). Another 54 patients who underwent laparotomy (LT group) were matched according to the patients\' baseline characteristics, causes of injury, and hemodynamic parameters. Perioperative clinical parameters and short-term survival were compared between these two groups.
The baseline characteristics were comparable between these two groups (LP vs. LT: Age, p = 0.112; Sex, p = 0.820; Injury severity score, p = 0.158; Cause distribution, p = 0.840). The most common cause was traffic accident (36.1%) and the most frequent surgical intervention was bowel repair/resection (34.3%) in our study. The operation time was similar in these two groups (LP vs. LT: 202.2 ± 72.58 vs. 194.11 ± 82.95 min, p = 0.295) while post-operative complication rate was slightly reduced in LP group (7.7% vs. 13.5%) with no statistical significance (p = 0.383). Opioid use was lower in the LP than LT group (11.67 ± 4.08 vs. 26.0 ± 13.42 morphine equivalents (MEQ), p = 0.034). The hospital stay was significantly shorter in the LP group (13.48 ± 10.9 vs. 18.64 ± 14.73 days, p = 0.021). One patient in the LT group died of an intra-abdominal abscess and multiple organ dysfunction syndrome 19 days postoperatively, while all patients in the LP group recovered and were discharged.
Laparoscopy is feasible and safe in treating abdominal trauma patients in hemodynamically stable conditions performed by experienced surgeons. Laparoscopy might have the advantages of reduced pain and quicker recovery with similarly favorable clinical outcomes.

BACKGROUND: The role of thrombolytic therapy for the initial treatment of hemodynamically stable patients experiencing an acute pulmonary embolism remains controversial.
RESULTS: We performed a meta-analysis of randomized trials comparing between administration of recombinant tissue plasminogen activator (rt-PA) and heparin in hemodynamically stable patients experiencing an acute pulmonary embolism. Seven trials, involving 594 patients, were included in this meta-analysis. Compared with heparin, rt-PA was associated with a non-significant reduction in death (2.75% versus 3.96%; RR 0.69, 95% CI 0.31-1.52, P for heterogeneity=0.520) and recurrent pulmonary embolism (2.13% versus 3.34%; RR 0.70, 95% CI 0.28-1.73), and a non-significant increase in major bleeding (5.15% versus 4.29%; RR 1.06, 95% CI 0.520-2.150). Similar results were found based on a subgroup analysis of patients displaying echocardiographic evidence of right ventricular dysfunction (RVD). In contrast, rt-PA treatment was associated with a significant reduction in escalation of care in trials that also enrolled patients displaying RVD compared with heparin treatment (6.56% versus 19.7%; RR 0.34, 95% CI 0.20-0.65).
CONCLUSIONS: The currently available data provide no evidence for a benefit of administration of rt-PA compared with heparin for the initial treatment of hemodynamically stable patients experiencing an acute pulmonary embolism. However, rt-PA is partially beneficial specifically among patients displaying RVD.
