Nasal trauma is a frequent complication of nCPAP, especially in preterm neonates, but long-term cosmetic sequelae are very rare. This study provides a description of nasal trauma and proposes a simple staging system. This could serve as a basis to develop strategies of prevention and treatment of this iatrogenic event.

The epidemiology of meconium aspiration syndrome (MAS) in term neonates is described in a population-based retrospective study of data recorded for all births from 2000 to 2007 in a French region (Burgundy). Of the 132 884 eligible term newborns, the rate of meconium-stained amniotic fluid (MSAF) was 7.93%. The prevalence of severe MAS was 0.067% in the overall population. MAS rate was 0.11% at 37-38 weeks of gestation (WG), 0.20% at 39–41 WG, and 0.49% at 42-43 WG. Factors independently associated with severe MAS were identified by a case-control study, that is, thick meconium amniotic fluid, fetal tachycardia, Apgar score ≤3 at 1 minute, and birth in a level III facility. Our results confirm the high prevalence of MSAF after 37 WG but also show the low frequency of severe MAS in a period corresponding to the new international recommendations on the management of birth with MSAF.

Maintaining appropriate sedation and analgesia in pediatric burn patients can be quite challenging and often requires high doses of analgesics and anxiolytics because tolerance quickly develops. Escalating doses of opioids and benzodiazepines provide little additional benefit while increasing the incidence of side effects. Dexmedetomidine (DEX) is a novel alpha2-adrenergic agonist that provides sedation, anxiolysis, and analgesia with much less respiratory depression than other sedatives. In addition, DEX stimulation of alpha2 receptors on pancreatic beta cells may inhibit insulin secretion. Hyperglycemia has not been studied specifically in patients receiving DEX. Therefore, we hypothesized that DEX would improve sedation compared with our standard sedation regimen. In addition, we studied the effects of DEX on blood glucose levels. We performed a retrospective chart review of 65 pediatric burn patients (42 boys, 23 girls) in the intensive care unit admitted between 2001 and 2004 who received DEX infusion because of failure to achieve adequate sedation with our standard regimen of opioids and benzodiazepines. We recorded age, TBSA burn size, weight, dose and duration of infusion, adequacy of sedation before and after initiation of DEX, blood glucose levels before and after DEX, and the presence or absence of mechanical ventilation. The mean age was 5 years (range, 0.6-17), burn size was 36% TBSA (range, 3-94), and weight was 26 kg (range, 8-100). All patients were rated "inadequately sedate" before DEX infusion was initiated at 0.2 mug/kg/hr and titrated to effect. Twenty-six patients received a loading dose of 1 mug/kg. The average duration of DEX infusion was 11 days (range, 2-50), and no tachyphylaxis was noted. The mean dose was 0.5 mug/kg/hr (range, 0.1-2). Infusions were weaned over the course of 12 to 24 hours without evidence of rebound hypertension or withdrawal. With DEX titration, all patients were rated "adequately sedate," even though all were sedation failures with opioids and benzodiazepines. Eleven of 42 patients receiving ventilatory support were extubated while on DEX infusion, and no patient showed evidence of DEX induced respiratory depression. Patient's blood glucose levels averaged 121.2 +/- 8.9 mg/dl while on DEX infusion and 117.1 +/- 12.1 mg/dl while off, a nonsignificant difference.
