Although patients with chronic kidney disease (CKD) who present for surgery are often instructed to stop certain medications preoperatively, a study from New York University Langone Medical Center has concluded that such cessation may be largely unnecessary. The researchers found that five common agents—angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers, diuretics, statins, insulin and calcium channel […]

Background: Misidentification of the cricothyroid membrane in a “cannot intubate-cannot oxygenate” situation can lead to failures and serious complications. The authors hypothesized that preprocedure ultrasound-guided identification of the cricothyroid membrane would reduce complications associated with cricothyrotomy. Methods: A group of 47 trainees were randomized to digital palpation […]

Terekhov et al Anesthesiology 11 2015, Vol.123, 1059-1066. doi:10.1097/ALN.0000000000000858 Background: Estimating surgical risk is critical for perioperative decision making and risk stratification. Current risk-adjustment measures do not integrate dynamic clinical parameters along with baseline patient characteristics, which may allow a more accurate prediction of surgical risk. The goal of this study was to determine […]
Read MoreThe American Heart Association has updated its comprehensive guidelines on cardiopulmonary resuscitation and emergency cardiovascular care. The update appears in Circulation. Among the more salient points for healthcare providers: The recommended chest compression depth is 2 to 2.4 inches at a rate of 100 to 120 per minute. To reduce the time to first compression, providers […]
Read MoreLatent class analysis and ASA physical status yield differing results Although perioperative risk stratification is often used to identify so-called independent risk factors, previous research has found that few are truly independent, and various combinations of comorbidities may have differential effects on mortality risk. Researchers turned to “latent class analysis,” a model-based clustering technique, and […]
