P-wave dispersion as a simple tool for screening childhood obstructive sleep apnea syndrome.

Introduction: The gold standard for the diagnosis of childhood obstructive sleep apnea syndrome (OSAS) diagnosis is polysomnography; however, electrocardiography (ECG) may provide a simpler alternative. P-wave dispersion (PWD), the difference between the maximum and minimum P-wave duration measured by 12-lead ECG, is increased in adult OSAS but has not been researched in childhood OSAS. The aims of this study were to determine the PWD and cut-off value for the diagnosis of childhood OSAS and its association with severity.

A Randomized Controlled Trial of Immediate versus Delayed Umbilical Cord Clamping in Multiple-Birth Infants Born Preterm.

Background: Delayed cord clamping (DCC) improves placental transfusion and increases blood volume in preterm infants when compared with immediate cord clamping (ICC). However, evidence to support DCC in multiple-birth preterm infants is still lacking.

Objective: To compare the outcomes of ICC versus DCC in preterm infants of multiple births.

Comparison of three non-invasive hemodynamic monitoring methods in critically ill children.

Introduction: Hemodynamic parameters measurements were widely conducted using pulmonary artery catheter (PAC) with thermodilution as a reference standard. Due to its technical difficulties in children, transthoracic echocardiography (TTE) has been widely employed instead. Nonetheless, TTE requires expertise and is time-consuming.

Ultrasound Versus Traditional Palpation to Guide Radial Artery Cannulation in Critically Ill Children: A Randomized Trial.

Objectives: To identify success rates for radial artery cannulation in a pediatric critical care unit using either palpation or ultrasound guidance to cannulate the radial artery.

Methods: A prospective randomized comparative study of critically ill children who required invasive monitoring in a tertiary referral center was conducted. All patients were randomized by a stratified block of 4 to either ultrasound-guided or traditional palpation radial artery cannulation.
