Use of tranexamic acid in primary total knee replacement: effects on perioperative blood loss.

Background And Objectives: The use of tranexamic acid in primary total knee replacement surgeries has been the subject of constant study. The strategies to reduce bleeding are aimed at reducing the need for blood transfusion due to the risks involved. In this study we evaluated the use of tranexamic acid in reducing bleeding, need for blood transfusion, and prevalence of postoperative deep vein thrombosis in primary total knee replacement.

[Airway management in Ludwig's angina - a challenge: case report].

Background: Ludwig's angina (LA) is an infection of the submandibular space, first described by Wilhelm Frederick von Ludwig in 1836. It represents an entity difficult to manage due to the rapid progression and difficulty in maintaining airway patency, a major challenge in medical practice, resulting in asphyxia and death in 8-10% of patients.

Objective: Describe a case of a patient with Ludwig's angina undergoing surgery, with emphasis on airway management, in addition to reviewing the articles published in the literature on this topic.

[Use of tranexamic acid in primary total knee replacement: effects on perioperative blood loss].

Background And Objectives: The use of tranexamic acid in primary total knee replacement surgeries has been the subject of constant study. The strategies to reduce bleeding are aimed at reducing the need for blood transfusion due to the risks involved. In this study we evaluated the use of tranexamic acid in reducing bleeding, need for blood transfusion, and prevalence of postoperative deep vein thrombosis (DVT) in primary total knee replacement.

Anesthesia for cesarean section in a patient with Guillain-Barre syndrome: Case report.

Background And Objectives: Guillain-Barre syndrome during pregnancy is considered a rare neurological complication, and there is no consensus in literature for anesthetic management for cesarean section in such patients. The objective of this paper is to report the case of a pregnant woman with Guillain-Barre syndrome undergoing cesarean section.

Case Report: Female patient, 22-year old, 35 weeks and 5 days of gestation, undergoing cesarean section, hospitalized, reporting decreased strength and lower limb paresthesias.

Occupational hazards and diseases related to the practice of anesthesiology.

Background And Objectives: The practice of anesthesiology is not without risks to the anesthesiologist. The operating room (OR), in which anesthesiologists spend most of their time, is regarded as an unhealthy workplace due to the potential risks it offers. In this review, we propose an analysis of the occupational hazards that anesthesiologists are exposed in their daily practice.

Anterior cervical interbody fusion with hydroxyapatite graft: clinical and radiological analysis of graft breakage.

Study Design: Prospective longitudinal cohort.

Objective: To evaluate the efficacy of hydroxyapatite (HA) grafts in combination with cervical plates in terms of fusion, restoration, and maintenance of cervical lordosis and to compare clinical and radiologic outcomes of patients who experienced graft breakage with patients who did not.

Summary Of Background Data: The most common complication related to the use of HA graft for cervical anterior fusion is graft breakage.

Intraosseous sacral paraganglioma with extradural extension: case report.

Background: Paragangliomas are tumors that arise from the paraganglion system, which is a component of the neuroendocrine system. Approximately 10% are located in the extra-adrenal paraganglion system. Paragangliomas of the spine, however, are rare.

Intramuscular myxoma of the cervical paraspinal muscle.

Myxoma is a neoplasm of mesenchymal origin composed of undifferentiated stellate cells in a myxoid stroma. This tumor can develop in a variety of locations. Myxomas that arise from skeletal muscles are called intramuscular myxomas.

[Dexmedetomidine as adjuvant drug for wake-up test during scoliosis correction surgery: case report.].

Background And Objectives: Scoliosis is a spinal defect very often requiring surgical correction. A uniqueness of this correction is the need for intraoperative emergence and leg movement (wake up test) to rule out central nervous system (CNS) injury after correction of the orthopedic defect. In our report, dexmedetomidine was associated to total intravenous anesthesia with propofol and remifentanil to induce sedation, analgesia and ventilatory stability during wake up test in patient submitted to surgical scoliosis correction.
