Abstract PDF PT

Objectives: To identify the frequency of risk factors, classification of degree of risk and the practice of prophylaxis to venous thromboembolism (VTE) in a general hospital. Methods: Randomly selected cases were included. Patients were excluded if they were on anticoagulant treatment. Determination of risk factors and classification of degree of risk were done according to international consensus. Results: Most patients (96%) had at least one recognized risk factor, 81% of them fulfilled the criteria to be classified as moderate/high risk. Prophylactic measures were prescribed to 221 (63%) patients. There was a significant association between the higher risk level for VTE and increased use of heparin (p < 0.001). Contraindications to the use of heparin were noticed in 7% of the cases. Conclusion: Risk factors for VTE are usually seen and prophylaxis is unsatisfactory. Contraindications to the use of heparin are uncommon; prophylaxis should be considered for a higher number of patients.

Objectives: To identify the degree of risk and the practice of prophylaxis to venous thromboembolism (VTE) in an intensive care unit (ICU). Methods: The subjects were patients admitted to the ICU between December 1997 and February 1998. Patients were excluded if they were in anticoagulant therapy or presented contra-indication to heparin. Determination of risk factors and classification of the degree of risk for VTE were done according to international consensus. The ICU medical staff did not know about the study. Results: The authors evaluated one hundred and eighty patients with a mean age of 58 years (±16.5). Risk factors more frequently found were: age ³ 40 years (85.0%), surgery (47.8%), thoracic or abdominal infection (22.8%). Two or more risk factors were present in 146 (81%) cases. In the evaluation of VTE risk, 142 (79%) patients were classified as moderate/high risk. Prophylactic measures were prescribed to 102 patients (57%), and heparin was used in 60% of moderate/high risk cases. There was a significant association between risk level and the number of risk factors with the use of prophylaxis (p < 0.05). Conclusion: VTE risk factors were frequent in the sample analyzed. However, 40% of patients considered moderate/high risk did not receive pharmacological prophylaxis for VTE.

Relationship between functional and X-ray alterations in patients with cystic fibrosis

Relação entre alterações funcionais e radiológicas em pacientes com fibrose cística

Abstract PDF PT

Background: Cystic fibrosis (CF) is a disease marked by airway inflammation and airflow obstruction, resulting in air trapping in the lungs. Objective: To assess the associations between airflow limitation, pulmonary volume and X-ray findings in patients with cystic fibrosis. Method: A cross-sectional retrospective study. Review of spirometric, plethysmographic, and chest X-ray findings of outpatients (age ³ 16 years). The airflow findings were classified as within normal limits or as airflow obstruction: mild, moderate or severe obstructive alteration. Results: A total of 23 patients (15 male and eight female; mean age, 21 ± 5.9 years) were studied. Six of them were within normal limits, four had a mild, five had a moderate, and eight had a severe obstructive alteration. There was an association between airflow limitation and the increase of residual volume (p = 0.006) and also with the Brasfield score (p = 0.001), but not with the total lung capacity (p = 0.33). There was a correlation between residual volume and Brasfield score (r = 0,73, p = 0,002), but not with the total pulmonary capacity. Moreover, according to X-ray criteria, the air trapping was correlated only with the residual volume (p = 0.006). Conclusion: In patients with cystic fibrosis (age ³ 16 years), the progressive airflow limitation is accompanied by an increase in residual volume, while the total pulmonary capacity remains normal or tends to decrease. The X-ray score was associated with airflow limitation and residual volume, but not with total lung capacity.
