Hemorrhage remains the leading cause of death in combat and the primary cause of preventable death after civilian trauma. Over the last 10 years, major improvements in hemostatic agents have resulted in new dressings that are replacing gauze as the standard of care for compressible hemorrhage. This has inspired a plethora of hemostatic products, some of which have been used in the combat and civilian sector. ⋯ Current research is ongoing to determine which of the available hemostatic agents is the most efficacious. The current recommendation by the Committee on Tactical Combat Casualty Care is that Combat Gauze™ (Z-Medica) is the hemostatic dressing of choice and every soldier carries this dressing in their first aid kit. This article reviews novel hemostatic agents used by first responders in the military and civilian sectors.

Over the past two decades, significant advances have been made in mitral valve surgery. Cardiac surgeons have successfully repaired degenerative and ischemic regurgitant mitral valves via a traditional midline sternotomy. In recent years, alternate incisions have yielded minimally invasive approaches to the mitral valve. ⋯ Decreased pain, more rapid return to work, diminished blood loss and reduced length of hospitalization have been witnessed following robotic mitral valve surgery when compared with a traditional sternotomy. Equivalent long-term mortality and freedom from recurrent mitral regurgitation are evident between mitral valve repair performed via a traditional sternotomy and minimally invasive and robotic techniques. As a result, an increasing number of patients and referring cardiologists are seeking minimally invasive approaches to mitral valve surgery.

ReviewCost-effectiveness of robotic-assisted laparoscopic procedures in urologic surgery in the USA.
New technologies such as robotic-assisted surgery are constantly introduced clinically without a complete understanding of benefits and costs. This article will discuss general concepts of health economics and apply them to the application of robotic-assisted surgery to urologic procedures. Utilization of robotic surgery has increased dramatically in recent years. ⋯ In order for the robot to be cost effective, there needs to be an improvement in efficacy over alternative approaches, and a decrease in costs of the robot or instrumentation. Robotic surgery has not been found to be cost effective in urology. Future studies may yet reveal indirect benefits that are not yet obvious.
