Comment ReviewCritical appraisal of Perez et al: Jugular venous oxygen saturation or arteriovenous difference of lactate content and outcome in children with severe traumatic brain injury.
To review the findings and discuss the implications of jugular venous bulb oxygenation monitoring in children with severe traumatic brain injury. ⋯ This study is the first to demonstrate that jugular venous monitoring may aid in predicting the neurologic outcome of children with severe traumatic brain injury. More studies need to be performed (particularly on safety) before adopting jugular venous bulb oxygenation monitoring as a prediction tool or, ultimately, as a therapeutic intervention to help manage and improve outcome for children with severe traumatic brain injury.

Comparative Study Clinical TrialTissue Doppler echocardiographic and color M-mode estimation of left atrial pressure in infants.
Using recorded flow and tissue Doppler, we evaluated the relation of peak velocity of early transmitral Doppler filling (E)/early diastolic velocity of the lateral mitral annulus (Ea) ratio and of E/flow propagation velocity (Vp) ratio to mean left atrial pressure in infants after surgery for congenital heart disease. ⋯ Doppler ratios might be considered as promising noninvasive tools for left atrial pressure evaluation in infants after cardiac surgery.

Clinical TrialProspective evaluation of dexmedetomidine for noninvasive procedural sedation in children.
Children often require sedation for lengthy noninvasive procedures. Conventional agents such as chloral hydrate, benzodiazepines, or barbiturates have been associated with sedation failure, respiratory depression, and paradoxic agitation. Dexmedetomidine is a newer alpha(2)-adrenergic receptor agonist with sedative properties and minimal respiratory depression. We hypothesized that it would be an effective agent for these procedures. ⋯ Dexmedetomidine provided effective sedation in children undergoing noninvasive procedures and represents an alternative sedative choice for this population.
