Urinary tract infection (UTI) is the leading cause of fever without a source in infants younger than 3 months. This data was collected from patients who presented to the emergency department with fever without a source over a 16 year period. Out of 2850 patients, 20.8% were diagnosed with a UTI, the majority of which grew E coli. Of those patients who were diagnosed with UTI, these patients were more likely to have a history of renal/GU problems, have a fever of at least 39C (38% vs 29%) or poor feeding (13% vs 8.7%). However, 48% had none of these risk factors. Also 6.1% of patients with a febrile UTI had another invasive bacterial infection. These patients were more likely to be < 1 month, be "irritable" per parents and have an elevated procalcitonin and CRP.
Bottom line: A lack of risk factors can not exclude a UTI in febrile infants < 3 months. A diagnosis of UTI also does not definitively exclude an additional invasive bacterial infection in a subset of these children.

The typical bag valve mask ventilator (BVM) for adults has a reservoir volume between 1500-2000 mL depending on the manufacturer while the volume is between 500-1000 mL for a pediatric BVM. When trying to obtain the recommended tidal volume of 6-8 mL/kg (500-600 mL for the typical adult), one thought was that a pediatric BVM could be used with adult patients so as to avoid iatrogenic barotrauma. This has been studied on manakins using an oral pharyngeal airway, supraglottic airway and endotracheal tubes (ETT) and has been successful. This study attempted to obtain the same results in the back of a moving ambulance. Paramedics and EMTs, squeezing pediatric and adult BVMs with one hand, bagged adult manakins in the back of a moving ambulance (without lights and sirens). The average tidal volume was recorded using various types of airways (i-gel, King airway and ETT).
Volumes delivered with the pediatric BVM were significantly lower than the tidal volumes with adult BVMs across all airway types suggesting that in the moving ambulance, using pediatric BVMs on an adult patient would not be appropriate.
The I-Gel and King airway provided similar tidal volumes which were not statistically different than volume delivered through the ETT.
EMTs consistently delivered 50% less tidal volumes compared to paramedics. The authors suggested that perhaps the additional training and pathophysiology knowledge that paramedics have could also be important with a skill that is considered basic.

This was a retrospective study involving several hospitals in Italy. 135 patients who had drowned (the term used in the article) were included. 4.5% of patients died. Most drowning occurred in July and August. The most common comorbidity was epilepsy in about 10% of patients. Several patients were also witnessed to have trauma and syncope. Early resuscitation, either by bystanders or trained professionals, was paramount in survival.
Children who are conscious at presentation and have mild or no respiratory distress have the best prognosis. A well appearing child should be observed for 6-8 hours, given that 98% of children will present with symptoms within the first 7 hours. A chest xray is not indicated in the asymptomatic patient. Patients who are submerged greater than 25 minutes or without ROSC after 30 minutes have a poor prognosis.
Bottom line: Never swim alone and everyone should be trained in bystander CPR.
Bystander CPR increases out-of-hospital CPR survival and direction by 911 telecommunicators increases the frequency of bystander CPR. The majority of 911 centers use Medical Priority Dispatch System which walks 911 telecommunicators through a series of questions that give different instructions based on the caller's answers. Studies have shown out-of-hospital cardiac arrests are only recognized between 79-92% of the time and telecommunicator instructions for CPR can take between 176-285 seconds.
This study reviewed recorded 911 calls of patients who were found to be in cardiac arrest. Calls where the caller was not with the patient and confirmed overdoses were some of the call types that were excluded.
Out of 65 reviewed calls, 28% were not recognized during the actual call. When they were reviewed, 8/18 of the calls were deemed to be recognizable. Themes that were noted were: incomplete or delayed recognition assessment (ie uncertainty in breathing), communication gaps (callers were confused with instructions or questions), caller emotional distress, delayed repositioning for chest compressions, non essential questions and assessments, and caller refusal/hesitation or inability to act.
Bottom line: In addition to bystander CPR training, education on the process and questions involved in calling 911 could be helpful in an emergency.

Should EMS place an advanced airway in out of hospital cardiac arrests? Current studies suggest that advanced airway management is not superior to BVM in pediatric out of hospital cardiac arrest (OHCA).
Pediatric OHCA carries a high mortality rate and those that do survive often have a poor neurologic outcome. This study evaluated BVM vs supraglottic airway (SGA) placement vs endotracheal intubation (ETI) in relation to one month survival and favorable neurological outcomes. SGA and ETI were also grouped together and categorized as advanced airway management (AAM).
This study was conducted using the Pan Asian Resuscitation Outcomes Study Clinical Research Network. 3131 pediatric patients were included. 85% received BVM, 11.8% SGA and 2.6 % ETI. In a matched cohort, one month survival and survival with favorable neurological outcome was higher in the BVM group compared to the AAM group and in the BVM group compared to the SGA group. There was no significant difference noted between the ETI group and BVM group.
Bottom line: In this study, AAM was associated with decreased one month survival and less favorable neurological status in pediatric OHCA.
