Cochrane Summary:

Croup is a common childhood illness which primarily affects those between the ages of six months and three years, with a peak annual incidence in the second year of life of nearly five per cent. Males and females are affected equally. Croup is most often caused by a viral infection. Symptoms of croup include a hoarse voice, a ‘barking’ cough and noisy breathing. These symptoms are the result of swelling that occurs in the area of the windpipe (trachea) just below the voice box (larynx). Although most cases of croup are mild and resolve on their own, occasionally the swelling can be severe enough to cause difficulty in breathing. In these children, epinephrine (also called adrenaline) is a medication that is inhaled as a mist to temporarily shrink the swollen area in the trachea.

This review looked at trials of inhaled epinephrine for the treatment of children with croup and is comprised of only eight studies with 225 participants. Of the eight included studies, six were assessed as having low risk of bias and two as unclear risk of bias (based upon assessment of adequate random sequence generation, allocations concealment, blinding of participants and personnel, blinding of outcome assessment, completeness of outcome data, and selective reporting). Studies assessed a variety of outcome measures and few studies examined the same outcomes; therefore, most outcomes contained data from a maximum of three studies, and in some cases only single studies.

Compared to no medication, inhaled epinephrine improved croup symptoms in children at 30 minutes following treatment (three studies, 94 children). This treatment effect disappeared two hours after treatment (one study, 20 children). However, children’s symptoms did not become worse than prior to treatment. No study measured adverse events.

The evidence is current to July 2013.

Authors’ Conclusions:

Nebulized epinephrine is associated with clinically and statistically significant transient reduction of symptoms of croup 30 minutes post-treatment. Evidence does not favor racemic epinephrine or L-epinephrine, or intermittent positive pressure breathing over simple nebulization. The authors note that data and analyses were limited by the small number of relevant studies and total number of participants and thus most outcomes contained data from very few or even single studies.

Prophylactic Antibiotics for Penetrating Abdominal Trauma

This week, as part of the Child Health Emergency Medicine Social Media Campaign, we are highlighting a Cochrane summary on prophylactic antibiotics for penetrating abdominal trauma. This review was selected for the TREKK Evidence Repository on multiple trauma.

Cochrane Summary:

Should prophylactic antibiotics be used in patients with penetrating abdominal trauma?

For over half a century antibiotics have been given to patients that have suffered from a penetrating injury to the abdominal peritoneal cavity in an attempt to decrease the incidence of post-operative wound infection, intra-abdominal infection and mortality. This review was designed to assess whether or not this practice is supported by medical evidence.

No randomised controlled trials could be found that met the inclusion criteria for this review. Therefore, there is no evidence to unequivocally support or refute this practice. Current guidelines are based on expert opinion rather than fact.

We recommend that a randomised controlled trial be designed to assess which patients would benefit from antibiotic prophylaxis, and which patients would not. Hopefully this would result in less unnecessary antibiotic use, and thus less antibiotic resistance.

Authors’ conclusions:

There is currently no information from randomised controlled trials to support or refute the use of antibiotics for patients with penetrating abdominal trauma.

High quality research is needed in this area so that evidence-based recommendations for treatment can be made. Check out the resources developed by TREKK for more information on what is currently known. Follow us @Cochrane_Child and @TREKKca for more on this topic throughout the week.
