ABSTRACT
OBJECTIVES: To summarize the effectiveness of critical care ultrasonography (CCUS) in adult patients with cardiogenic shock vs. standard of care without CCUS on patient-relevant outcomes.
DESIGN: We performed a scoping review across MEDLINE, Embase, CENTRAL, World Health Organization, International Clinical Trials Registry, ClinicalTrials.gov, and published and unpublished sources from inception until February 2024.
SETTING: The emergency department, ward, or ICU.
PATIENTS: We included randomized clinical trials (RCTs) and observational studies comparing CCUS to non-CCUS care in adult patients with cardiogenic shock. We included any type of ultrasound measure for the intervention in adult patients (≥ 18 yr old).
INTERVENTIONS: CCUS.
MEASUREMENTS AND MAIN RESULTS: We included two RCTs (n = 573 patients) and one observational study (n = 30 patients). RCT data suggested that CCUS, with transesophageal echocardiography in particular, in adult patients with cardiogenic shock may shorten time to resolution of hemodynamic instability at 72 hours (subhazard ratio [SHR], 1.26; 95% CI, 1.02-1.55) but failed to influence mortality (risk difference, -0.03; 95% CI, -0.1 to 0.05), time to resolution of hemodynamic instability within 6 days (SHR, 1.20; 95% CI, 0.98-1.46), ICU length of stay (LOS; p = 0.87), hospital LOS (p = 0.91), duration of mechanical ventilation (p = 0.73), or duration of renal replacement therapy (RRT; p = 0.68).
CONCLUSIONS: In adult patients with cardiogenic shock, CCUS does not impact mortality, time to resolution of hemodynamic instability within 6 days, ICU and hospital LOS, nor mechanical ventilation or RRT duration. Notably, CCUS may hasten resolution of hemodynamic instability at 72 hours, but such evidence is limited by imprecision and indirectness.
