Review
Molecular mechanisms of action of systemic lidocaine in acute and chronic pain: a narrative review.
The systemic antinociceptive effects of lidocaine occur by mechanisms other than sodium channel blockade, including silencing of ectopic discharges, inflammatory suppression, and neurotransmission modulation.

Observational Study
The effect of i-gel® insertion on the accuracy of cricothyroid membrane identification in adult females: a prospective observational study.
Identification of the cricothyroid membrane is frequently inaccurate in females because of less distinct anatomy compared with males. Supraglottic airway devices cause ventral displacement of the laryngeal structures. We investigated if this would impact on the accuracy of cricothyroid membrane identification using palpation. ⋯ The presence of the i-gel® improved accuracy of identifying the cricothyroid membrane using palpation in females. The cricoid cartilage was pushed ventrally by the i-gel® in the hypopharynx, creating a more palpable prominence. It may therefore be advantageous to retain a sited supraglottic airway, rather than remove it, before performing emergency cricothyroidotomy.

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.

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.
