Randomized Controlled Trial
Intraoperative use of dexmedetomidine for the prevention of emergence agitation and postoperative delirium in thoracic surgery: a randomized-controlled trial.
We investigated whether preventive use of dexmedetomidine during surgery was effective for reducing emergence agitation and postoperative delirium. ⋯ Intraoperative dexmedetomidine reduced emergence agitation but not postoperative delirium in patients undergoing thoracic surgery. Dexmedetomidine seemed to affect emergence agitation through catecholamines, but not through an anti-inflammatory action. Trial registration Clinical Research Information Service (KCT 0001877); registered 7 April, 2016.

This module will introduce the concept of a point-of-care ultrasound (POCUS) examination for perioperative clinicians. A focused cardiac examination of ventricular filling and function is presented. An examination of the inferior vena cava is also reviewed as a tool to assess volume status. ⋯ Limited ultrasound cardiorespiratory examinations can be performed by non-cardiologists and non-radiologists. Information drawn from POCUS may aid in diagnosis and early rescue in perioperative care. Point-of-care ultrasound is likely to become standard of care for anesthesiologists in the same way that stethoscopy is presently.
