Sepsis involves imbalance between the proinflammatory and antiinflammatory response to bacterial insults. Ulinastatin (UTI) is a serine protease inhibitor and reportedly exhibits antiinflammatory properties aside from its blocking of the protease pathway both in vitro and in vivo. This study was designed to investigate the potential therapeutic efficacy of UTI for sepsis. ⋯ UTI exerted a protective effect against sepsis by suppressing inflammatory response and lymphocyte apoptosis.

Unplanned reoperations have been proposed as a quality indicator in surgery but have not been studied extensively, especially concerning risk factors. ⋯ Tertiary general surgery service patients had a significantly increased risk of being reoperated on if the initial surgery was an emergency surgery compared with elective surgery. Unplanned reoperations led to a significantly increased mortality risk and a longer postoperative hospital stay, which could be regarded as warning signs in the care of surgical patients.

Experimental hemorrhagic shock (HS) is based on controlling bleeding and the treatment of fluid resuscitation to restore tissue oxygenation and perfusion. The HS could promote ischemia/reperfusion injury, which induces a general exacerbation of the inflammatory process, initially compromising the lungs. N-acetylcysteine (NAC), an antioxidant, may attenuate ischemia/reperfusion injury. This study evaluated the effect of NAC in association with fluid resuscitation on pulmonary injury in a controlled HS model in rats. ⋯ N-acetylcysteine was associated with fluid resuscitation-attenuated oxidative stress and inflammatory cell infiltration in pulmonary parenchyma. N-acetylcysteine did not modify cytokine expression.

Hemorrhage within an intact abdominal cavity remains a leading cause of preventable death on the battlefield. Despite this need, there is no existing closed-cavity animal model to assess new hemostatic agents for the preoperative control of intra-abdominal hemorrhage. ⋯ This model can be used to screen other interventions for pre hospital control of noncompressible.

Nonoperative management of hemodynamically stable children and adolescents with splenic injury regardless of grade has become standard; however, numerous studies have shown a wide variation in management. We compared the treatment and outcomes of adolescent splenic injuries in our region, which includes a pediatric level I trauma center (PTC) and an adult level I trauma center (ATC). ⋯ Our study demonstrates that the location of presentation was independently associated with splenectomy while controlling for a higher injury severity score at the ATC. With the higher percentage of nonoperative management, treatment at the PTC was not associated with an increased LOS (total or intensive care unit).
