Severe injury and associated hemorrhagic shock lead to an inflammatory response and subsequent increased tissue damage. Numerous reports have shown that injury-induced inflammation and the associated end-organ damage is driven by Toll-like receptor 4 (TLR4) activation via damage-associated molecular patterns. We examined the effectiveness of Eritoran tetrasodium (E5564), an inhibitor of TLR4 function, in reducing inflammation induced during hemorrhagic shock with resuscitation (HS/R) or after peripheral tissue injury (bilateral femur fracture, BFF). ⋯ These data suggest Eritoran can inhibit tissue damage and inflammation induced via TLR4/myeloid differentiation factor 2 signaling from damage-associated molecular patterns released during HS/R or BFF. Eritoran may represent a promising therapeutic for trauma patients to prevent multiple organ failure.

Meta Analysis
A meta-analysis of the effectiveness and safety of using tranexamic acid in primary unilateral total knee arthroplasty.
To evaluate the effectiveness and safety of tranexamic acid (TEA) treatment in reducing perioperative blood loss and transfusion for patients receiving primary unilateral total knee arthroplasty (TKA) and to explore the most effective and safe protocol. ⋯ Intravenous TEA could significantly reduce perioperative blood loss and blood transfusion requirements following primary unilateral TKA. Its application is not associated with increased risk of venous thromboembolisms or other adverse events.

Despite a growing body of literature supporting the limited use of prophylactic intra-abdominal drainage for many procedures, drain placement after pancreatic resection remains commonplace and highly controversial. ⋯ The current literature supports a strategy of selective drainage and early drain removal after pancreatic resection in low-risk patients.

Prolonged elevated blood lactate levels strongly correlate with poor outcomes in a variety of critically ill patients. We hypothesized that the dynamic postoperative changes in blood lactate levels during the first 24 h were significantly associated with postoperative morbidity and mortality in patients undergoing elective major abdominal surgery. ⋯ The dynamic changes in blood lactate levels during the first 24 postoperative h were significantly associated with complications after major elective abdominal surgery. This result warrants a "golden hour and silver day" perspective of early resuscitation in this patient cohort.

Case Reports
Augmented environments for the targeting of hepatic lesions during image-guided robotic liver surgery.
Stereotactic navigation technology can enhance guidance during surgery and enable the precise reproduction of planned surgical strategies. Currently, specific systems (such as the CAS-One system) are available for instrument guidance in open liver surgery. This study aims to evaluate the implementation of such a system for the targeting of hepatic tumors during robotic liver surgery. ⋯ The da Vinci Surgical System provided an excellent platform for image-guided liver surgery with a stable optic and instrumentation. Robotic image guidance might improve the surgeon's orientation during the operation and increase accuracy in tumor resection. Further developments of this technological combination are needed to deal with organ deformation during surgery.
