Randomized Controlled Trial Comparative Study
Ultrasound-guided lung sliding sign to confirm optimal depth of tracheal tube insertion in young children.
The tip of the tracheal tube should lie at the mid-tracheal level after tracheal intubation in paediatric patients. Auscultation does not guarantee optimal positioning of the tracheal tube. We compared auscultation and the ultrasound-guided lung sliding sign to confirm optimal positioning of the tracheal tube in paediatric patients. ⋯ KCT 0003015.

Evidence-based international expert consensus regarding anaesthetic practice in hip/knee arthroplasty surgery is needed for improved healthcare outcomes. ⋯ neuraxial anaesthesia is recommended for hip arthroplasty given associated outcome benefits; evidence level: moderate-low, strong recommendation. Based on current evidence, the consensus group recommends neuraxial over general anaesthesia for hip/knee arthroplasty.

Emergence from sedation entails rapid increase in the levels of both awareness and wakefulness, the two axes of consciousness. Functional MRI (fMRI) studies of emergence from sedation often focus on the recovery period, with no description of the moment of emergence. We hypothesised that by focusing on the moment of emergence, novel insights, primarily about subcortical activity and increased wakefulness, will be gained. ⋯ Emergence from propofol sedation is characterised, and possibly driven, by a transient activation of brainstem loci. Some of these loci are known components of the ascending reticular activating system, whereas an additional locus was found that is also impaired in comatose patients.

Observational Study
Incidence of and risk factors for venous thrombosis in children with percutaneous non-tunnelled central venous catheters.
Venous thrombosis (VT) in children is often associated with a central venous catheter (CVC). We aimed to determine the incidence of VT associated with percutaneous non-tunnelled CVCs in a general paediatric population, and to identify risk factors for VT in this cohort. ⋯ ACTRN12615000442505.

Our goal is to develop metrics that quantify the translation of performance from cadavers to patients. Our primary objective was to develop steps and error checklists from a Delphi questionnaire. Our second objective was to show that our test scores were valid and reliable. ⋯ Our tests to quantify ultrasound-guided interscalene nerve block training and performance were valid and reliable.
