BACKGROUND: Spinal cord stimulation (SCS) is a common intervention for managing intractable pain. Generally, leads are implanted in a minimally invasive procedure with verbal feedback regarding the location and nature of generated paresthesias by active stimulation; in this way their optimal location can be confirmed. However, lead placement under general anesthesia can have additional benefits. OBJECTIVE: To investigate the outcomes of awake vs asleep lead placement procedures...

Introduction: To achieve the aim of zero preventable deaths on the battlefield a deeper understanding of uncontrolled hemorrhage from junctional or proximal extremity sources is mandatory. While tourniquet application to the extremities has drastically reduced morbidity and mortality, there is still room for improvement regarding the timing of tourniquet placement as the available evidence clearly points out a tight correlation between timing of tourniquet application and outcome. To save as many lives as possible the "point of no return" regarding the circulatory breakdown due to hemorrhage, colloquially addressed as platinum 5 min, needs to be determined...

BACKGROUND AND OBJECTIVE: While Minimally Invasive Surgery (MIS) offers considerable benefits to patients, it also imposes big challenges on a surgeon's performance due to well-known issues and restrictions associated with the field of view (FOV), hand-eye misalignment and disorientation, as well as the lack of stereoscopic depth perception in monocular endoscopy. Augmented Reality (AR) technology can help to overcome these limitations by augmenting the real scene with annotations, labels, tumour measurements or even a 3D reconstruction of anatomy structures at the target surgical locations...

BACKGROUND: Ketorolac tromethamine (Toradol) is an effective a nonsteroidal anti-inflammatory drug and a powerful analgesic for patients undergoing breast surgery. However, the potential for postoperative bleeding has not yet been explored specifically in women undergoing implant-based breast reconstruction. There is concern that an increased risk of bleeding exists in this population due to the lack of tissue apposition as a result of implant placement. We therefore seek to assess the associated risk of bleeding complication in implant-based breast reconstruction at our academic institution...
