Review
Anesthetic management of patients with Brugada syndrome: a case series and literature review.
To review the anesthetic management and perioperative outcomes of patients diagnosed with Brugada syndrome (BrS) who were treated at a single centre and to compare those results with a comprehensive review of the existing literature. ⋯ In this series and in the literature, BrS patients tolerated anesthesia without untoward disease-related complications. Propofol and local anesthetics carry a theoretical risk of arrhythmogenic potential in BrS patients, but clear evidence is lacking. However, awareness of their potential to induce arrhythmias warrants caution, especially with propofol infusions. Factors that might exacerbate ST segment elevations and subsequently lead to dysrhythmias (e.g., hyperthermia, bradycardia, and electrolyte imbalances, such as hyper- and hypokalemia and hypercalcemia) should be avoided or corrected.

Randomized Controlled Trial Comparative Study
The McIvor blade improves insertion of the LMA ProSeal™ in children.
The McIvor blade, a tongue retractor with a thin curved blade, is used to improve the operating field during a tonsillectomy. We compared the success rate and incidence of complications between digital insertion and McIvor blade-guided insertion of the laryngeal mask airway (LMA™) ProSeal™ when performed by anesthesia residents in children. ⋯ When inserting the LMA ProSeal in children, anesthesia residents were more successful using the McIvor blade-guided insertion technique than using the digital insertion technique. (ClinicalTrials.gov number, NCT01191619).

Randomized Controlled Trial
Cricoid pressure with the Truview Evo2™ laryngoscope improves the glottic view.
The Truview Evo2™ laryngoscope blade is designed to improve glottic view. This study was designed to evaluate the effect of cricoid pressure (CP) on laryngeal view and the ease of orotracheal intubation with the Truview Evo2 laryngoscope. ⋯ When using the Truview Evo2™ laryngoscope with the patient's head in the neutral position, application of CP improves the glottic view. This approach is not associated with increased difficulty in intubation.

The anesthetic management of women with severe aortic stenosis (AS) undergoing Cesarean delivery (CD) remains controversial. We used a relatively new bioreactance technology to highlight the continuous hemodynamic changes related to anesthesia, delivery, and recovery in a parturient with severe AS. ⋯ Continuous CO data obtained from bioreactance-based monitoring suggests that pregnant women with severe AS may experience an increase in CO under certain circumstances. This result is in keeping with data obtained from non-pregnant individuals and is an interesting finding that warrants further study. Noninvasive CO monitoring may improve our understanding of the peripartum changes in women with heart disease.
