Objective:  Bronchopulmonary dysplasia (BPD) is the most common late morbidity for premature infants. Continuous neuromuscular blockade (CNMB) is suggested for the most unstable phase of BPD, despite no outcome data. We explored the association between duration of CNMB for severe BPD and mortality.

Purpose: The opioid epidemic continues to result in significant morbidity and mortality even within hospitals where opioids are the second most common cause of adverse events. Opioid stewardship represents one model for hospitals to promote safe and rational prescribing of opioids to mitigate preventable adverse events in alliance with new Joint Commission standards. The purpose of this study was to identify the prevalence of current hospital practices to improve opioid use.

Background Over 6000 children have an in-hospital cardiac arrest in the United States annually. Most will not survive to discharge, with significant variability in survival across hospitals suggesting improvement in resuscitation performance can save lives. Methods and Results A prospective observational study of quality of chest compressions ( CC ) during pediatric in-hospital cardiac arrest associated with development and implementation of a resuscitation quality bundle.

Purpose: An interprofessional initiative to operationalize outpatient naloxone prescribing at a large academic medical center is described.

Summary: The initiative was carried out by a work group of clinical pharmacists and pharmacy administrators in collaboration with physicians and nursing staff leaders from multiple practice settings. An opioid overdose risk-assessment guide was developed on the basis of literature review and expert opinion.

Objective: We aimed to increase detection of pediatric cardiopulmonary resuscitation (CPR) events and collection of physiologic and performance data for use in quality improvement (QI) efforts.

Materials And Methods: We developed a workflow-driven surveillance system that leveraged organizational information technology systems to trigger CPR detection and analysis processes. We characterized detection by notification source, type, location, and year, and compared it to previous methods of detection.

Objective: Anaphylaxis is a life-threatening event. Most clinical symptoms of anaphylaxis can be reversed by prompt intramuscular administration of epinephrine using an auto-injector or epinephrine drawn up in a syringe and delays and errors may be fatal. The aim of this scoping review is to identify and compare errors associated with use of epinephrine drawn up in a syringe versus epinephrine auto-injectors in order to assist hospitals as they choose which approach minimizes risk of adverse events for their patients.

We present the use of a low-resistance membrane oxygenator (Quadrox D, Maquet) in series with a pulsatile right ventricular assist device (Berlin Heart EXCOR, Berlin Heart) in a patient with biventricular support who required high-frequency oscillatory ventilation (HFOV), due to refractory acute respiratory distress syndrome associated with Cytomegalovirus pneumonia. The high mean airway pressure associated with the use of HFOV resulted in a significant negative impact on left ventricular assist device (LVAD) filling that led to a combined respiratory and metabolic acidosis and the need for vasopressor support. Oxygenator placement enabled transition to conventional ventilation and the discontinuation of vasopressor support.

Objectives: To determine whether time to prepare IV medications for hyperkalemia varied by 1) drug, 2) patient weight, 3) calcium salt, and 4) whether these data support the Advanced Cardiac Life Support recommended sequence.

Design: Prospective randomized simulation-based study.

Setting: Single pediatric tertiary medical referral center.

Objective: Hyperkalemia is one of the reversible causes of cardiac arrest in children. The Advanced Cardiovascular Life Support guidelines have specific recommendations on the choice and sequence of medications for treatment of life-threatening hyperkalemia. However, the Pediatric Advanced Life Support guidelines have no specific treatment recommendations.

The purpose of this study was to determine the efficacy of inhaled epoprostenol for treatment of acute pulmonary hypertension (PH) in pediatric patients and to formulate a plan for a prospective, randomized study of pulmonary vasodilator therapy in this population. Inhaled epoprostenol is an effective treatment for pediatric PH. A retrospective chart review was conducted of all pediatric patients who received inhaled epoprostenol at a tertiary care hospital between October 2005 and August 2007.
