Randomized Controlled Trial Comparative Study Clinical TrialChoice of opioid supplementation for day-case rigid bronchoscopy:a randomized placebo-controlled comparison of a bolus of remifentanil and alfentanil.
To compare the efficacy of different bolus doses of remifentanil, alfentanil, and saline at controlling the hemodynamic responses to day-case rigid bronchoscopy under general anesthesia. ⋯ A bolus of 2 micro g/kg of remifentanil successfully attenuated the hemodynamic response to rigid bronchoscopy without delaying recovery.

Comparative StudyChronic exposure to nicotine does not prevent neurocognitive decline after cardiac surgery.
To establish the association between smoking and cognitive decline in patients undergoing coronary artery bypass graft (CABG) surgery. ⋯ This study confirmed previous findings that age, baseline cognitive function, years of education, and impaired left ventricular function are independent predictors of neurocognitive decline at 6 weeks after CABG surgery. Smoking is neither preventive nor causative of cognitive decline after CABG surgery.

Comparative Study Clinical TrialDifficult laryngoscopy: incidence and predictors in patients undergoing coronary artery bypass surgery versus general surgery patients.
Cardiac surgery patients might have a higher incidence of difficult laryngoscopy than the general population because of older age, dental problems, and obesity. The authors estimated the incidence and predictors of difficult laryngoscopy in coronary artery bypass surgery patients. ⋯ Difficult laryngoscopy was more frequent in cardiac surgery patients (10% v 5.2%). Older age and limited neck movement, but not cardiac surgery per se, were independent predictors of difficult laryngoscopy.

Comparative StudyThe relationship between the diameters of the adult cricoid ring and main tracheobronchial tree: a cadaver study to investigate the basis for double-lumen tube selection.
Previous investigation of the adult cadaver larynx has shown that the cricoid diameter never exceeds that of the glottis. This further analysis looks at the anatomic relationships between the diameter of the cricoid ring and those of the main tracheobronchial tree to discover how they relate to double-lumen tube selection. ⋯ The dimensions of the cricoid ring best define those of the main bronchi. Knowing its diameter should assist anesthesiologists with double-lumen tube selection.
