Preoperative X-ray CCAR is applicable for prediction of difficult laryngoscopy in patients with cervical spondylosis.

BMC Anesthesiol 2021 Apr 12;21(1):111. Epub 2021 Apr 12.

Department of Anesthesiology, Peking University Third Hospital, Peking University Health Science Center, 49 North Garden Road, Haidian District, Beijing, P.R. China.

Background: Airway management is one of the most important techniques in anesthesia practice and inappropriate airway management is related with airway injury, brain hypoxia, and even death. The patients with cervical spondylosis are often confronted with difficult laryngoscopy who are more prone to appear difficult airway, so it is important to figure out valuable predictors of difficult laryngoscopy in these patients.

Methods: We randomly enrolled 270 patients undergoing elective cervical spine surgery and analyzed the cervical mobility data in predicting difficult laryngoscopy. Read More

Exploring the impact of the COVID-19 pandemic on pediatric surgical services: a scoping review.

Minerva Pediatr (Torino) 2021 Apr 12. Epub 2021 Apr 12.

Department of Cardiovascular Medicine, University of Louisville, Louisville, KY, USA.

Inevitably, along with other healthcare specializations, pediatric surgery was affected by the Coronavirus disease-19 (COVID-19) pandemic. Children were reported to manifest mild to moderate symptoms and mortality was primarily observed in patients aged <1 year and having underlying comorbidities. The majority of the cases were asymptomatic in children, hence, posing a challenge for pediatric surgery centers to take drastic measures to reduce the virus transmission. Read More
