Pediatric cardiac arrest in the emergency department: Outcome is related to the time of admission

Factors affecting early antibiotic delivery in open tibial shaft fractures

INTRODUCTION

The incidence of infection in open tibial shaft injuries varies with the severity of the injury with rates ranging from roughly 2% for Gustilo-Anderson type I to nearly 43% for type IIIB fractures. As with all fractures, timely antibiotics administration in the emergency department (ED) is an essential component of fracture management and infection prevention. This study identifies factors associated with the expedient administration of antibiotics for open tibial shaft fractures.

METHODS

This retrospective study identified patients treated for open tibial shaft fractures at an academic level 1 trauma center between 2015 and 2021. Open fractures were identified by reviewing patient charts. We used chart reviews to gather demographics, fracture characteristics, postoperative outcomes, trauma activation, and time to antibiotic order, delivery, and operating room. Univariate analysis was used to compare patients who received antibiotics within 1 h of ED presentation to those who did not. Multivariate analysis was performed to investigate factors associated with faster delivery of antibiotics.

RESULTS

Among 70 ED patients with open tibial shaft fractures, 39 (56%) received early administration of antibiotics. Arrival at the ED via emergency medical service (EMS) as opposed to walking in (98% vs. 74%, p = 0.01) and trauma activation (90% vs. 52%, p < 0.001) were significantly more common in the early administration group than the late group. The early group had shorter intervals between antibiotic order and delivery (0.02 h vs. 0.35 h, p = 0.007). Multivariate analysis suggested that trauma activation, EMS arrival, and arrival during non-overnight shifts were independent predictors of a shorter time to antibiotic administration (odds ratios 11.9, 30.7, and 5.4, p = 0.001, 0.016, and 0.013, respectively).

DISCUSSION

Earlier antibiotic delivery is associated with non-overnight arrival at the ED, arrival via EMS, and a coordinated trauma activation. Our findings indicate that in cases where administering antibiotics is critical to achieving positive outcomes, it is advisable to initiate a coordinated trauma response. Furthermore, hospital personnel should be attentive to the need for rapid administration of antibiotics to patients with open fractures who arrive via walk-in or during late-night hours.

Pediatric Cardiac Arrest Outcomes in the United States: A Nationwide Database Cohort Study

Background Knowledge about the causes and outcomes of pediatric cardiac arrest in the emergency department is limited. The aim of our study was to evaluate the characteristics and outcomes of pediatric cardiac arrest in the emergency department (EDCA) and inpatient (IPCA) settings in the United States using a large database designed to provide nationwide estimates. Methods We performed a retrospective cohort study using the Nationwide Emergency Department Sample (NEDS), a database that includes both ED and inpatient encounters. The NEDS was analyzed for episodes of cardiac arrest between 2016-2018 in patients aged ≤18 years. Patients with cardiac arrest were identified using the International Classification of Diseases, 10th revision codes. Results A total of 15,348 pediatric cardiac arrest events with cardiopulmonary resuscitation were recorded, of which 13,239 had EDCA and 2,109 had IPCA. A lower survival rate of 19% was observed for EDCA compared to 40.4% for IPCA. While more than half of the EDCA events had no associated diagnoses, trauma (15.6%), respiratory failure (5%), asphyxiation (2.7%), acidosis (2.4%), and ventricular arrhythmia (1.4%) were associated with the remaining events. In comparison, the most frequently associated diagnoses for IPCA were respiratory failure (75.8%), acidosis (43.9%), acute kidney injury (27.2%), trauma (27.1%), and sepsis (22.5%).  Conclusions Survival rates for EDCA were less than half of that for IPCA. The low survival rates along with the distinctive characteristics of EDCA events suggest the need for further research in this area to identify remediable factors and improve survival.

Effects of regional differences on the outcome of cardiopulmonary resuscitation in children: How much different is Gaziantep from Izmir?

OBJECTIVES:

We aimed to compare the demographic and clinical characteristics between pediatric cardiac arrest patients treated in Gaziantep at South-eastern Anatolian region and Izmir at Aegean Shore.

MATERIALS And METHODS:

We retrospectively reviewed sociodemographic characteristics, laboratory parameters, and clinical outcomes of pediatric patients that underwent cardiopulmonary resuscitation due to prehospital cardiac arrest at two pediatric emergency departments in Izmir Hospital of Health Sciences University and Gaziantep Cengiz Gökçek Kadın Doğum ve Çocuk Hospital of Health Ministry between August 2017 and August 2018.

RESULTS:

The present study included 188 patients (112 patients from Gaziantep and 76 patients from Izmir). All patients arrived at the hospital through emergency medical services. The median age was lower (14 days vs. 15 months; P < 0.001), and the proportion of Syrian refugees was higher in patients from Gaziantep (78.6% vs. 7.9%; P < 0,001). In both centers, respiratory failure was the most common etiology. In patients from Gaziantep, pH levels were lower (median: 7.10 vs. 7.24), and lactate levels were higher (median: 6 mmol/L vs. 3.6 mmol/L; P < 0.001). The mortality rate was higher among patients from Gaziantep (27.7% vs. 7.9%; P = 0.001).

CONCLUSIONS:

The rate of Syrian refugees among children who were brought to emergency department due to pre-hospital cardiac arrest was much higher in Gaziantep compared to Izmir. Syrian children were significantly younger and had more severe tissue hypoxia, resulting in a higher mortality rate.
