The success rate of intravenous catheter placement at the pediatric emergency department could be improved by experienced providers. The acuity of disease and crowdedness at the pediatric emergency department were not significantly associated factors.

Our new formula is useful and more accurate than the currently available methods.

Intussusception is one of the most common causes of intestinal obstruction in young children. We report a retrospective, observational study of the epidemiology of intussusception in South Korea using the National Health Insurance Service-National Sample Cohort (NHIS-NSC). A cohort of newborns born between 2002 and 2008 was selected. The primary objective was to assess the incidence of intussusception in the pediatric population of Korea. The secondary objectives were to describe the basic epide

Tattooing is becoming more popular around the world. As a result, the reported complications of tattoo are increasing. Local inflammation, infection and allergic reactions are the most common adverse effects. We report here on a healthy 39-year-old woman who developed multiple verruca plana lesions after undergoing semipermanent tattooing. The tattooing had been done 1 year earlier by an amateur.

Children feature more active cellular division and a smaller body area, which leads to a greater radiation dosage accumulation. We tried to reduce radiation hazards by reducing unnecessary radiological studies in a pediatric emergency department (PED) through the radiation reduction campaign.Our campaign involved a reduction from 2 (erect and supine) to 1 ordered abdominal plain radiograph (erect). This quasi-experimental, uncontrolled before-and-after study aimed to evaluate the campaign effect

<b>Objective:</b> We evaluated the validity of a newly developed mobile application (i.e. the Weighing Cam) for pediatric weight estimation compared with that of the Broselow tape. <b>Methods:</b> We developed an application that estimates the weight of pediatric patients using a smartphone camera and displays the drug dosage, device size, and defibrillation energy on the screen of the smartphone. We enrolled a convenience sample of pediatric patients aged <16 years who presented at two pediatri

Foreign body (FB) injuries mainly occur in young children and may cause serious complications. The purpose of this study was to describe the epidemiological and clinical characteristics of FB injuries among children visiting the emergency department (ED) in South Korea and to compare the incidence and the ED results of FB injuries.Using data from the National Emergency Department Information System, FB injury-related ED visits among children (<7 years) between January 2010 and December 2014 were

<b>Objective:</b> We developed a novel compression assist device (palm presser) to perform chest compressions using a palm in infant cardiopulmonary resuscitation (CPR). We hypothesized that the palm presser will increase compression depth without increasing hands-off time and will reduce rescuer fatigue compared with the two-finger technique (TFT).<b>Methods:</b> In this randomized crossover manikin trial, participants performed two minutes of CPR with a 30:2 compression:ventilation ratio using

Two pagurid species, Pagurus quinquelineatus Komai, 2003 and Pagurus rectidactylus Komai, Saito &amp; Myorin, 2015, are reported from South Korea. Pagurus nigrivittatus is most similar to these two species among the congeneric species known from South Korea. The additional morphological differences between P. quinquelineatus and P. rectidactylus are provided briefly. The most distinct feature of the South Korean P. rectidactylus compared to the original description is that an associated hydrozoa

The rolling tape is a good weight estimation tool for children compared with other methods. The rolling tape method significantly decreased the time from weight estimation to orders for essential drug dose, instrument size and defibrillation dose for resuscitation.
