BACKGROUND Ultrasound (US) examination has many uses in resuscitation, but to use it to its full effectiveness typically requires a trained and proficient user. We sought to use information technology advances to remotely guide US-naive examiners (UNEs) using a portable battery-powered tele-US system mentored using either a smartphone or laptop computer.

BACKGROUND Point-of-care ultrasound (POC-US) use is increasingly common as equipment costs decrease and availability increases. Despite the utility of POC-US in trained hands, there are many situations wherein patients could benefit from the added safety of POC-US guidance, yet trained users are unavailable. We therefore hypothesized that currently(More)
BACKGROUND Elevated base deficit (BD) and lactate levels at admission in patients with injury have been shown to be associated with increased mortality. This relationship is undefined in the Canadian experience. The goal of this study was to define the association between arterial blood gas (ABG) values at admission and mortality for Canadians with severe(More)
The choice of the optimal surgical approach for repairing paraesophaeal hernias (PEH) is debated. Our objective is to evaluate the short-term outcomes of primary laparoscopic and open repairs of PEH performed in the Calgary Health Region. A retrospective review of all patients undergoing repair of PEH between October 1999 and February 2005 was performed.(More)
BACKGROUND Despite a widespread shift to selective non-operative management (SNOM) for blunt splenic trauma, there remains uncertainty regarding the role of adjuncts such as interventional radiological techniques, the need for follow-up imaging, and the incidence of long-term complications. We evaluated the success of SNOM (including splenic artery(More)
BACKGROUND Worldwide ultrasound equipment accessibility is at an all-time high, as technology improves and costs decrease. Ensuring that patients benefit from more accurate resuscitation and diagnoses from a user-dependent technology, such as ultrasound, requires accurate examination, typically entailing significant training. Remote tele-mentored ultrasound(More)
BACKGROUND Patients with an occult pneumothoraces (OPTXs) may be at risk of tension pneumothoraces (TPTXs) without drainage or pleural drainage complications if treated. METHODS Adults with traumatic OPTXs and requiring positive-pressure ventilation (PPV) were randomized to pleural drainage or observation (one side only enrolled if bilateral). All(More)
OBJECTIVE To determine whether active negative pressure peritoneal therapy with the ABThera temporary abdominal closure device reduces systemic inflammation after abbreviated laparotomy. BACKGROUND Excessive systemic inflammation after abdominal injury or intra-abdominal sepsis is associated with poor outcomes. METHODS We conducted a single-center,(More)
