Meta Analysis
A systematic review of lidocaine-prilocaine cream (EMLA) in the treatment of acute pain in neonates.
Neonates routinely undergo painful cutaneous procedures as part of their medical treatment. Lidocaine-prilocaine 5% cream (EMLA) is a topical anesthetic that may be useful for diminishing the pain from these procedures. EMLA is routinely used in children and adults. There is substantial apprehension about its use in neonates because of concerns that it may cause methemoglobinemia. The objective of this review was to determine the efficacy and safety of EMLA as an analgesic for procedural pain treatment in neonates and provide evidence-based recommendations for clinical practice. ⋯ Eleven studies of the efficacy of EMLA were included in the analysis. Infant gestational age at the time of delivery ranged from 26 weeks to full-term. Two studies included data from both neonates and older infants. The following procedures were studied: circumcision (n = 3), heel lancing (n = 4), venipuncture (n = 1), venipuncture and arterial puncture (n = 1), lumbar puncture (n = 1), and percutaneous venous catheter placement (n = 1). Nine studies were randomized controlled trials. The total sample size for each study ranged from 13 to 110 neonates. The dose of EMLA used was 0.5 g to 2 g in 9 studies, and was not specified in the others. The duration of application ranged from 10 minutes to 3 hours. The three studies that investigated the efficacy of EMLA for decreasing the pain of circumcision used a randomized controlled trial design. All of them demonstrated significantly reduced crying time during the procedure in the infants in the EMLA group compared with the infants in the control group. Facial grimacing, assessed in two of the studies, was also significantly lower in the EMLA group. Using meta-analytic techniques, the heart rate outcome data for two studies was summarized. Increases in heart rate compared with baseline values were 12 to 27 beats per minute less for the EMLA group than in the placebo group during various stages of the surgical procedure. Three studies that investigated the pain from heel lancing were randomized controlled trials; the other was a nonrandomized controlled study. None demonstrated a significant benefit of EMLA for any of the outcome measures used to assess pain (ie, behavioral pain scores, infant crying, heart rate, blood pressure, respiratory rate, oxygenation parameters). One randomized controlled study of the pain from venipuncture showed that infants treated with EMLA had significantly lower heart rates and cry duration compared with infants treated with a placebo. In one nonrandomized study, a significantly lower behavioral pain score was observed for infants treated with EMLA compared with the control group. Infant heart rate, however, did not differ between the groups. In one randomized controlled study of pain from percutaneous venous catheter placement, EMLA resulted in a significantly lower increase in heart rate and respiratory rate. Behavioral pain scores were significantly lower during arterial puncture in one nonrandomized controlled study. EMLA did not reduce physiologic changes or behavioral pain scores in one randomized controlled trial in infants undergoing lumbar puncture. Meta-analytic techniques revealed that methemoglobin concentrations did not differ between EMLA-treated and placebo-treated infants (weighted mean di

Comparative Study
Safety of hospitalized ventilator-dependent children outside of the intensive care unit.
Hospitalization of clinically stable ventilator-dependent children in an intensive care unit (ICU) remains the standard in most pediatric centers. The aim of this study was to determine whether chronically ventilator-dependent children could be hospitalized safely in a non-ICU setting. ⋯ We conclude that ventilator-dependent children hospitalized outside of the ICU do not have an increased incidence of deaths and unexpected ICU admissions compared with nonventilator-dependent inpatients. We speculate that hospital care of stable ventilator-dependent children can be provided safely outside of an ICU and at lower cost.

To measure the effect of environmental tobacco smoke (ETS) on respiratory health in a national sample of young children. ⋯ ETS exposure is common among children in the United States. The reported prevalence of asthma, wheezing, and chronic bronchitis was increased with ETS exposures. No statistically significant increase in the prevalence of upper respiratory infection, pneumonia, or cough was associated with ETS exposure. ETS exposure has little effect on the respiratory health of children between 3 and 5 years of age, with the exception of asthma. ETS appears to increase the prevalence of asthma rather than the severity as measured by medication use. These findings reinforce the need to reduce the exposure of young children to ETS.

Since the 1990 publication of a decision analysis, in which the treatment of pharyngitis in children was evaluated, a number of assumptions important in that analysis have changed. Updating many of the assumptions and costs used in that analysis to reflect the conditions currently found in a large, suburban pediatric practice, a cost-effectiveness analysis was performed in which four strategies for the treatment of pharyngitis were considered: treat all, high-sensitivity antigen test, culture, and high-sensitivity antigen test with culture confirmation. ⋯ Although most cost-effective, the treat-all strategy is not recommended because of concerns about antibiotic resistance, which could not be included in the model, and the high number of allergic reactions found in children who did not have streptococcal infection. Use of the high-sensitivity antigen test without culture confirmation of all negative results was the most cost-effective strategy in which a diagnostic test was used with respect to prevention of suppurative and nonsuppurative complications of streptococcal pharyngitis. Culture confirmation of negative high-sensitivity antigen tests was not cost-effective under any of those conditions currently seen in the United States.

To determine the reasons for placement of children in foster care, the prevalence of medical findings during initial placement, and the relationship between reason for placement and medical findings. The association between placement reasons and parental substance abuse also was explored. ⋯ Specific medical findings associated with reasons for placement provide health professionals with additional information to assess more accurately the health care needs of children entering foster care. As important, screening tests revealed high rates of vision problems and exposures to tuberculosis, warranting earlier and more comprehensive screening. Finally, children who have endured variations of neglect or failed placement may have more health problems than anticipated previously.
