Randomized Controlled Trial
Replacing a double-lumen tube with a single-lumen tube or a laryngeal mask airway device to reduce coughing at emergence after thoracic surgery: a randomized controlled single-blind trial.
Coughing episodes occur frequently at extubation after thoracic surgery, and this may be due in part to the double-lumen tube (DLT). In this study, the DLT was replaced with either a single-lumen endotracheal tube (ETT) or a laryngeal mask airway (LMA) device or left in place, and the incidence of coughing at emergence was compared between the three groups. ⋯ Coughing at extubation after thoracic surgery can be reduced if the DLT is replaced by an LMA-P before emergence. The number of patients in this trial was too small to evaluate the risks associated with exchanging the airway device. This trial was registered at ClinicalTrials.gov: NCT00925613.

The abuse of substances available to anesthesiologists in their workspace is a potentially lethal occupational hazard. Our primary objective was to define the prevalence of substance abuse cases among Canadian anesthesiologists at university-affiliated hospitals. Our secondary aim was to describe the current management of confirmed cases, rehabilitation procedures being offered, and preventative strategies being employed. ⋯ The prevalence of substance abuse among Canadian anesthesiologists and the substances abused appear comparable with data from the United States, with residents being the group most often affected. Early recognition and treatment of chemically dependent anesthesiologists remain imperfect.
