Resumen de Central venous cannulation
Central venous access is an important component of care of the critically ill cardiac patient, as a tool for monitoring, delivery of fluids, vasoactive agents and drugs. Placement carries associated risks, with morbidity approaching 40% using traditional landmark techniques. Ultrasound offers the clinician real-time imaging of the vascular lumen during insertion, with associated risk reduction. With improvements in training and cheaper equipment, ultrasound guidance has become the gold standard to guide insertion of central venous lines. Additionally, emerging evidence in the use of lung ultrasound means that it may be used immediately post-procedure to screen for the presence of pneumothorax.
