Randomized Controlled Trial
The effect of tranexamic acid on hemoglobin levels during total knee arthroplasty.
The aim of this study was to evaluate the efficacy of perioperative administration of 1,4-amino-carboxylic acid (tranexamic acid) in reducing the intraoperative and postoperative blood loss in patients undergoing total knee replacement (TKR). Tranexamic acid is an antifibrinolytic agent that is 7-10 times as potent as epsilon aminocaproic acid. ⋯ In the study group, the drug was administered in 2 doses 1 hour preoperatively and 6 hours postoperatively. The use of tranexamic acid injection in TKR surgeries can be considered as an effective method to control and minimize the blood loss during total knee arthroplasty surgeries.

Up to 2008, dopamine was the catecholamine that was the most recommended in our intensive care unit (ICU) after fluid resuscitation. However, recently, norepinephrine has become the catecholamine that was most recommended in our ICU after fluid resuscitation. The aim of this study was to determine if there was an efficacy or safety benefit to this protocol therapeutic change in patients with shock admitted to our ICU. ⋯ The occurrence of arrhythmias was significantly more frequent in the first group. Mortality rate was at 51% in the first group and 44% in the second group (P = 0.27). The mortality rate was not significantly different for each type of shock (septic, cardiogenic, and hypovolemic) in both groups (P > 0.05 for all), although the occurrence of arrhythmias was significantly more frequent in the first group, in clinical practice, our study confirms that the rate of death did not differ significantly between the 2 groups of patients mostly treated with dopamine (group 1) and the group mostly treated with norepinephrine.

Epidural hematoma is a major complication that can occur when neuraxial anesthesia is used concurrently with newer anticoagulation and antiplatelet medications. In complex hospital environments, the opportunity of performing a neuraxial procedure in an anticoagulated patient or starting potent anticoagulants on a patient with existing epidural catheter still exists. We describe a technique to use an electronic clinical decision support ordering system that helps reduce this risk of epidural hematoma. ⋯ Before initiating the alert system, we had 26 events noted in the medical chart over a 3-month period. We noted only 11 events after the initiation of the new alert systems and clinical decision support in a similar 3-month period. Using electronic clinical decision support systems can help reduce medication errors related to neuraxial anesthesia and anticoagulation medications in a large hospital system.

Clostridium difficile infection (CDI) is the leading cause of antibiotic-associated and nosocomial infectious diarrhea. Presenting as clostridium difficile colitis, it is a significant cause of morbidity and mortality. Metronidazole is regarded as the agent of choice for CDl therapy and also for the first recurrence in most patients with mild to moderate CDI. ⋯ Role of toxin-binding agents is still questionable. Monoclonal antibody and intravenous immunoglobulin are still investigational therapies that could be promising options. The ongoing challenges in the treatment of CDI include management of recurrence and presence of resistance strains such as NAP1/BI/027, but early recognition of surgical candidates can potentially decrease mortality in CDI.
