Multicenter Study Observational Study
Local anaesthetic dosage of peripheral nerve blocks in children: analysis of 40 121 blocks from the Pediatric Regional Anesthesia Network database.
The knowledge regarding appropriate dosage of local anaesthetics for peripheral nerve blocks in children is very scarce. The main objective of the current investigation was to evaluate dosing patterns of local anaesthetics in children receiving peripheral nerve blocks across multiple paediatric hospitals in the USA. We also sought to estimate the incidence of local anaesthetic systemic toxicity. ⋯ We detected a large variability in the local anaesthetic dosing practices for peripheral nerve blocks in children across multiple hospitals in the USA. Nonetheless, the risk of local anaesthetic systemic toxicity was very low. Due to the lack of dose findings studies, our results suggest the need to develop practice guidelines to minimize variability of regional anaesthesia practices in children.

I.V. and perineural dexamethasone have both been found to prolong loco-regional analgesia compared with controls without dexamethasone. It is unclear whether perineural administration offers advantages when compared with i.v. dexamethasone. ⋯ There is evidence that perineural dexamethasone prolongs the duration of analgesia compared with i.v. dexamethasone. Using GRADE, this evidence is low quality.

Observational Study
Efficacy of a new dual channel laryngeal mask airway, the LMA®Gastro™ Airway, for upper gastrointestinal endoscopy: a prospective observational study.
Significant cardiorespiratory events are frequent in patients undergoing gastrointestinal endoscopy. Central to the occurrence of respiratory events is an unsecured airway. This study sought to determine the efficacy of a new laryngeal mask airway, the LMA®GastroTM Airway (Teleflex Medical, Athlone, Ireland), in patients undergoing upper gastrointestinal endoscopy. New design features include a dedicated channel for oesophageal intubation and separate channel with terminal cuff for lung ventilation. ⋯ ACTRN12616001464459.
