Meta Analysis
The use of tranexamic acid to reduce blood loss and transfusion in major orthopedic surgery: a meta-analysis.
Conflicting reports have been published regarding the effect of tranexamic acid (TXA) on reducing blood loss and transfusion in patients undergoing orthopedic surgery. We performed a meta-analysis to evaluate the effectiveness and safety of TXA treatment in reducing blood loss and transfusion in major orthopedic surgery. ⋯ TXA significantly reduced blood loss and blood transfusion requirements in patients undergoing orthopedic surgery, and did not appear to increase the risk of DVT.

Meta Analysis
The role of remote ischemic preconditioning in organ protection after cardiac surgery: a meta-analysis.
Remote ischemic preconditioning (RIPC) appears to protect distant organs from ischemia-reperfusion injury. We undertook meta-analysis of clinical studies to evaluate the effects of RIPC on organ protection and clinical outcomes in patients undergoing cardiac surgery. ⋯ RIPC provides cardiac protection, but there is no evidence of renal or pulmonary protection in patients undergoing cardiac surgery using cardiopulmonary bypass. Larger multicenter trials are required to define the role of RIPC in surgical practice.

The vagina is the most widely used approach to natural orifice transluminal endoscopic surgery. However, a gas leak can significantly affect transvaginal operations during pneumoperitoneum laparoscopy. We tried to establish the proper technique for transvaginal appendectomy under gasless laparoscopy. ⋯ Transvaginal appendectomy with gasless laparoscopy after vaginal hysterectomy appears to be a feasible and safe modification of established techniques, with acceptable outcomes.

Although hyperglycemia has been associated with poor postoperative outcomes, preoperative hyperglycemia is not used as a screening tool in patients without diabetes. We evaluated preoperative glucose as a marker for postoperative outcomes in patients without diabetes to assess its usefulness as a potential screening tool. ⋯ In patients without known diabetes, preoperative glucose is a significant marker for postoperative complications even at moderate levels of hyperglycemia. Some of these patients likely had prediabetes or unrecognized diabetes at the time of surgery. Further studies are needed to determine whether such screening and follow-up of preoperative hyperglycemia in all patients would be effective in lowering complication rates.

Most studies have categorized all antiplatelet drugs into one category. The aim of our study was to evaluate the utility of repeat head computed tomography (RHCT) and outcomes in patients on low-dose aspirin (acetylsalicylic acid; ASA) therapy. ⋯ Low-dose aspirin therapy is not associated with progression of initial insult on RHCT or clinical deterioration. Prehospital low-dose aspirin therapy as a sole criterion should not warrant a routine repeat head CT in traumatic brain injury.
