ABSTRACT
Patients undergoing cardiac surgery are at high risk of postoperative bleeding, which is related to worse prognosis and survival. The use of ROTEM®, together with the implementation of a specific treatment algorithm, to reduce the risk of postoperative bleeding. An observational, comparative, cross-case study with historical controls. A total of 1772 consecutive patients admitted to intensive care unit after having undergone cardiac surgery, was divided into 3 groups: Group 1: Coagulation was only monitored by the classical coagulation test (control group). Group 2: Monitorization was done by ROTEM®, according to a protocol designed in our center. Group 3: VerifyNow® was added to ROTEM®, implementing a specific treatment algorithm. We observed a decreased of red blood cell transfusion (Group 1 55.5%, Group 2 52.7%, Group 3 46.6%, P<0.01). Postoperative results include a significant reduction in complications with a marked improvement in overall survival in the ROTEM® - guided groups. Conclusions: Monitoring of hemostasis by POCT'S (ROTEM® and VerifyNow®) in patients undergoing cardiac surgery and cardiac transplantation was associated with a decreased incidence of blood transfusion, postoperative clinical complications, and mortality.

Idiopathic inflammatory myopathies are a group of acquired, heterogeneous, systemic diseases commonly regarded as autoimmune disorders. Differential diagnosis includes muscular dystrophies, especially the dysferlin-deficiency myopathy. We report a case of a patient diagnosed with polymyositis and with associated autoimmune diseases that finally turned out to be a dysferlin deficiency (limb girdle muscular dystrophy type 2B). A possible link between dysferlin deficiency an autoimmunity is discussed.

BACKGROUND: Activated leukocytes may increase morbidity in cardiac surgery. The objective of this study is to investigate the influence on morbidity of leukocyte-depleting blood filters placed into the arterial line of cardiopulmonary bypass circuits. METHODS: Simple, blind, prospective, randomized and controlled clinical trial carried out in a cardiac surgery ICU at a university center. We included 159 consecutive low-risk patients (ie, Parsonnet score < 10) undergoing cardiac surgery who were initially stratified in three risk levels according to the Parsonnet score at admission into the hospital (ie, low, < 4; middle, 4 to 7; and high, 8 to 10). Once stratified, all patients were randomized to undergo cardiopulmonary bypass either with a conventional blood filter or with a leukocyte filter (randomization ratio, 2:1). The outcome variable was morbidity. Patients were considered to have a high morbidity if any of the following clinical situations were present (ie, pulmonary dysfunction, cardiac dysfunction, perioperative infections, postoperative hyperthermia, and hyperdynamic states). RESULTS: The leukocyte filter was used in 52 patients and the conventional filter in 107 patients. The morbidity rate was similar in both groups, but patients with leukocyte filter had a lower incidence of perioperative infections, fever, and hyperdynamic states as compared with patients with the conventional filter. CONCLUSIONS: Leukocyte filtration in patients undergoing cardiac surgery with extracorporeal perfusion showed no measurable effects on postoperative morbidity. However, although not statistically significant, a decrease was observed in the rates of perioperative infection, fever, and hyperdynamic states.
