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.

The objective of our study was to analyze plenary abstracts since 2006, when the Association for Academic Surgery (AAS) and Society of University Surgeons (SUS) began hosting the combined annual Academic Surgical Congress (ASC). Plenary session abstracts from the separate AAS and SUS meetings from 2002 to 2004 had previously revealed no significant difference in the scientific impact of published manuscripts. ⋯ After the initiation of the joint ASC meeting in 2006, the SUS and AAS plenary presentations continue to exhibit high-quality research. This study supports the benefit of a joint meeting for the AAS and SUS, as it has been associated with an increasing overall scientific impact for plenary abstracts.

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.

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.

Hyperoncotic albumin may be a therapeutic option to improve tissue perfusion and organ injury in sepsis. To clarify the hypothesis and its mechanism, hyperoncotic albumin was administered to the rats in a polymicrobial sepsis-peritonitis model. ⋯ In this sepsis rat model, 25% albumin reduced macro- and microhemodynamic changes and attenuated intestine and lung injuries in peritonitis-induced sepsis.
