Oxygen delivery through a Frova Intubating Introducer may be life-saving, and gas flow characteristics through this device have been described. Nevertheless, the feasibility of using a self-inflating resuscitation bag to deliver air or oxygen through this device has not been assessed. We compared volumes of air delivered and peak pressures generated with normal and maximal bimanual compression of a self-inflating resuscitation bag connected to a 70 cm Frova Intubating Introducer. ⋯ Clinically useful, life-sustaining volumes of air can be delivered using normal and maximal bimanual compression of a self-inflating resuscitation bag connected to a 70 cm Frova Intubating Introducer.

In the article entitled: "Carfentanil: a narrative review of its pharmacology and public health concerns" published online and in the April 2019 issue of the Journal, Can J Anesth 2019; DOI: https://doi.org/10.1007/s12630-019-01294-y , the Figure showed the wrong structures for remifentanil and carfentanil. This is now corrected in the accompanying revised figure and legend.

Review Meta Analysis
Preoperative intravenous dexamethasone prevents tracheal intubation-related sore throat in adult surgical patients: a systematic review and meta-analysis.
Why is this relevant?
Sore throat following endotracheal intubation is common (reported in up to 68%), and along with postoperative nausea & vomiting, negatively impacts postoperative well-being.
Small studies have previously suggested that IV dexamethasone reduces sore throat due to intubation. It is thought this occurs by reducing mucosal inflammation at the point of tracheal cuff contact, the presumed aetiology of the majority of post-ETT sore throat.
Kuriyama and Maeda conducted a systematic review and meta-analysis of 15 RCTs totalling 1,849 patients.
And they found?
Preoperative dexamethasone IV (~4-10 mg across the studies) reduced the incidence of sore throat by almost 40% (RR 95% CI 0.51-0.75) and mean severity by 1.1 (SMD 95% CI 1.8-0.3).
Take-home...
Given the established effectiveness of preoperative dexamethasone to safely reduce post-operative nausea and vomiting, this meta-analysis affirms another important indication for the routine use of dexamethasone in intubated patients who do not have contraindications to steroid use.

Acute kidney injury (AKI) is defined as an abrupt decrease in kidney function, with the most severe form requiring some method of renal replacement therapy (RRT). The use of RRT is required in 5-10% of critically ill patients who develop severe AKI. ⋯ Continuous renal replacement therapy may be run in different modes of increasing complexity depending on a given patient's clinical needs. Regional citrate anticoagulation is recommended as the therapy of choice for the majority of critically ill patients requiring CRRT.
