Observational Study
Accuracy of Transthoracic Lung Ultrasound for Diagnosing Anesthesia-induced Atelectasis in Children.
The aim of this study was to test the accuracy of lung sonography (LUS) to diagnose anesthesia-induced atelectasis in children undergoing magnetic resonance imaging (MRI). ⋯ LUS is an accurate, safe, and simple bedside method for diagnosing anesthesia-induced atelectasis in children.

The FLUSH Study-Flush the Line and Ultrasound the Heart: Ultrasonographic Confirmation of Central Femoral Venous Line Placement.
Inadvertent arterial placement of a femoral venous catheter may result in serious morbidity, including limb necrosis. The Flush the Line and Ultrasound the Heart (FLUSH) test is visualization of the heart by a subxiphoid ultrasonic view while the central catheter is flushed with agitated saline solution. We wish to determine whether the FLUSH test can verify proper femoral venous line placement. ⋯ The FLUSH test is simple and reliable, and appears to accurately confirm femoral venous line placement.

Recent studies suggest that phase-rectified signal averaging (PRSA), measured in antepartum fetal heart rate (FHR) traces, may sensitively indicate fetal status; however, its value has not been assessed during labour. We determined whether PRSA relates to acidaemia in labour, and compare its performance to short-term variation (STV), a related computerised FHR feature. ⋯ DC(PRSA) of the FHR can be measured in labour, and appears to predict acidaemia more accurately than STV. Further prospective evaluation is warranted to assess whether this could be clinically useful. The weak correlation between DC(PRSA) and STV suggests that they could be combined in multivariate FHR analyses.

Comparison of Gastroesophageal Reflux Disease Questionnaire (GerdQ) and Multi-channel Intraluminal Impedance-pH Monitoring in Identifying Patients with Chronic Cough Responsive to Anti-reflux Therapy.
Empirical therapy has been recommended as an initial clinical approach for treating gastroesophageal reflux-induced chronic cough (GERC). This study compared the predictive accuracy of the Gastroesophageal Reflux Disease Questionnaire (GerdQ) with the accuracy of multichannel intraluminal impedance pH monitoring (MII-pH) for GERC. ⋯ The GerdQ can be used for predicting acid GERC but not nonacid GERC and is inferior to MII-pH.

Reports of the burden of hypertension in hospitalized children are emerging, but the prevalence and significance of this condition within the PICU are not well understood. The aims of this study were to validate a definition of hypertension in the PICU and assess the associations between hypertension and acute kidney injury, PICU length of stay, and mortality. ⋯ Hypertension is common in the PICU and is associated with worse clinical outcomes. Future studies are needed to confirm these results.
