Microfracture is the most common cartilage-reparative procedure for treatment of osteochondral lesions talus (OLTs). Damage to subchondral bone (SCB) during microfracture may irreversibly change joint-loading support ankle, leading reparative fibrocartilage degradation over time.To investigate morphological in SCB after OLT by developing a novel magnetic resonance imaging (MRI) scoring system specifically evaluating SCB. Furthermore, this study assesses influence changes on clinical outcomes...

To characterize chest compression (CC) pause duration during the last 5 minutes of pediatric cardiopulmonary resuscitation (CPR) prior to extracorporeal-CPR (E-CPR) cannulation and association with survival outcomes.Cohort study from a quality collaborative including E-CPR cardiac arrest events ≥ 10 min CPR data. We characterized CC interruptions defibrillator-electrode recorded (prior cannulation) assessed between longest outcomes using multivariable logistic regression.Of 49 events, median...

Importance Cardiopulmonary resuscitation (CPR) duration is associated with cardiac arrest survival. Objectives To describe characteristics CPR among hospitalized children without return of circulation (ROC) (patient-level analysis) and determine whether hospital median in patients ROC survival (hospital-level analysis). Design, Setting, Participants This retrospective cohort study undergoing pediatric in-hospital between January 1, 2000, December 31, 2021, used data from the Get With...

IMPORTANCE: A recent study showed an association between high hospital-level noninvasive positive pressure ventilation (NIPPV) use and in-hospital cardiac arrest (IHCA) in children with bronchiolitis. OBJECTIVES: We aimed to determine if patient-level exposure NIPPV bronchiolitis was associated IHCA. DESIGN, SETTING AND PARTICIPANTS: Retrospective cohort at a single-center quaternary PICU North America including International Classification of Diseases primary or secondary diagnoses the...

Abstract Systems to detect and respond deteriorating hospitalized children are common despite little evidence supporting best practices. Our objective was describe systems detect/respond at Pediatric Resuscitation Quality Collaborative (pediRES‐Q) institutions. We performed a cross‐sectional survey of pediRES‐Q leaders. Questionnaire design utilized expert validation cognitive interviews. Thirty centers (88%) responded. Most (93%) used ≥1 system deterioration: most commonly, early warning...

Abstract Objective We aimed to describe the risk factors and outcomes of recurrent in-hospital cardiac arrest (IHCA) in a large pediatric cohort. Methods A retrospective cohort study patients ≤18 years from American Heart Association's Get With The Guidelines®-Resuscitation Registry with single or IHCA who achieved return spontaneous circulation were not placed on extracorporeal membrane oxygenation their initial included. Patients categorized into two groups for analysis: (1) (2) ICHA....

Abstract Background Black patients have worse outcomes after in-hospital cardiac arrest (IHCA). Whether these racial disparities are associated with medical emergency team (MET) evaluation prior to IHCA remains unknown. Methods A retrospective cohort study of adults age ≥ 18 years from the American Heart Association Get With The Guidelines® Resuscitation registry who had an between 2000 and 2021 acute physiologic decline (modified early warning score [MEWS] 3) during 24 hours IHCA....

Background: CPR quality is an important modifiable component of cardiac arrest care. Current chest compression (CC) guidelines were primarily generated from out-of-hospital data. However, they are applied to arrests in all contexts, including in-hospital. Aims: We aimed to: 1) quantitatively describe in-hospital (IHCA) CC metrics; 2) determine the association current AHA guideline-recommended metrics with IHCA outcomes; and 3) discover new targets using data quantify their outcomes....

Introduction: The physiologic response to epinephrine during pediatric CPR varies and poor is associated with worse outcomes. Though vasopressin not recommended by guidelines, laboratory data show a among non-responders. We aimed explore the IHCA. Hypothesis: Vasopressin an increase in diastolic blood pressure (DBP) compared patients ≥1 dose of epinephrine. Methods: Single-center retrospective cohort study ICU IHCAs prospectively collected arrest event (2017-2023). subjects received...
