Randomized Controlled Trial Comparative Study
Topical silver sulfadiazine vs collagenase ointment for the treatment of partial thickness burns in children: a prospective randomized trial.
The 2 most commonly used topical agents for partial thickness burns are silver sulfadiazine (SSD) and collagenase ointment (CO). Silver sulfadiazine holds antibacterial properties, and eschar separation occurs naturally. Collagenase ointment is an enzyme that cleaves denatured collagen facilitating separation but has no antibacterial properties. Currently, there are no prospective comparative data in children for these 2 agents. Therefore, we conducted a prospective randomized trial. ⋯ There are no differences in outcomes between topical SSD or CO in the management of childhood burns results.

The purpose of this study was to characterize epidemiologic trends and cost implications of hospital readmission after treatment of pediatric appendicitis. ⋯ In freestanding children's hospitals, readmission after treatment of pediatric appendicitis is a relatively common and costly occurrence. Collaborative efforts are needed to characterize patient, treatment, and hospital-related risk factors as a basis for developing preventative strategies.

Massive small bowel resection (SBR) results in villus angiogenesis and a critical adaptation response within the remnant bowel. Previous ex vivo studies of intestinal blood flow after SBR are conflicting. We sought to determine the effect of SBR on intestinal hemodynamics using photoacoustic microscopy, a noninvasive, label-free, high-resolution in vivo hybrid imaging modality. ⋯ Massive SBR results in an immediate reduction in intestinal blood flow and increase in tissue oxygen utilization. These physiologic changes are observed throughout the remnant small intestine. The contribution of these early hemodynamic alterations may contribute to the induction of villus angiogenesis and the pathogenesis of normal intestinal adaptation responses.

Endothelin-1, prostaglandins (PGs), and nitric oxide (NO) have been implicated in the intestinal microvascular dysfunction of necrotizing enterocolitis (NEC). We hypothesized that direct peritoneal resuscitation (DPR) dilates the intestinal microvasculature and improves blood flow independent of these mechanisms. ⋯ Ileal blood flow was significantly reduced in NEC animals as compared with CONTROLs. The addition of DPR to the peritoneum increased ileal blood flow significantly in all groups in spite of blockade of these known vasoactive mechanisms. Direct peritoneal resuscitation may be a novel strategy to improve intestinal blood flow in NEC.

Randomized Controlled Trial Comparative Study
Evaluation of a new pediatric intraosseous needle insertion device for low-resource settings.
The Near Needle Holder (NNH) (Near Manufacturing, Camrose, Alberta, Canada) is a reusable tool to introduce a standard hollow needle for pediatric intraosseous (IO) infusion. We compared the NNH to the Cook Dieckmann (Cook Critical Care, Bloomington, IN) manual IO needle in a simulation setting. ⋯ After training, all subjects successfully inserted the NNH IO device in a simulation environment, and most rated it as easy to use and safe. The NNH is a significant advance because IO needles are often not available in emergency departments in developing countries. Further studies are needed to evaluate clinical effectiveness of the NNH.
