Br J Haematol ; J Am Soc Nephrol ;9: Rheological influences on thrombosis. Patients Patients over 18 years of age, with a history of chronic lung disease, hypoxemia at admission and diagnostic impression of exacerbation of, infectious or non-infectious, chronic lung disease were selected.

Determining tratamientk virtual implications of red cell parameters in patients with pulmonary exacerbations could eirtrocitosis defining the particular use of measures such as phlebotomy or red blood cell transfusion. Pulmonary vascular disease in adults with congenital heart disease. The evaluation began the day of admission of the patient to the institution until day 30 of follow-up. Regarding the outcomes, there was a predilection to higher length hospital stay in the presence of lower levels of hematocrit.

For bivariate analysis, the Mann-Whitney U test was performed. Leuk Lymphoma ; published online 29 Jul. This is why the diagnosis reported by the patient and relatives was chosen, making it difficult to determine which patients actually had a chronic lung disease and which type. Patients with congenital heart disease, for whom diagnosis of exacerbation of lung disease was discarded at discharge, and those who did not wish to participate in the study were excluded from the study.

The qualitative variables were reported as absolute and relative frequencies. By contrast, other prognostic factors found to be related with exacerbations in other studies, such as age, use of home oxygen, the presence of signs of respiratory distress at admission, the number of Anthonisen criteria present and blood gases, could not be validated in this cohort 2,5,22,23, Hemorheology in the erythrocytoses.

Hematocrit and the risk of cardiovascular disease—the Framingham study: Type of chronic lung disease. The frequency of anemia was 7. Erythrocytosis could affect the prognosis of an exacerbation by altering the microvascular rheology of patients and decreasing tissue perfusion and cardiac output 6,7.


Cerebral blood flow and blood viscosity in patients with polycythaemia secondary to hypoxic lung disease. The results suggest the need for further studies to clarify the relevance of erythrocyte parameters in exacerbations of chronic lung disease, both at sea level and in populations located at higher altitudes, as in this case. History of ischemic heart disease.

When assessing the data by dividing the sex distribution and the hematocrit levels in the 25th and 75th percentiles Table 2 in order to debug the virtual relationships of the different levels of red cell parameters with the characteristics of the cohort, no relationship between hematocrit values and NYHA functional class of patients, nor between severity of exacerbation according to the criteria of Anthonisen was evident.

Since the NYHA functional class and the use of medications did not differ due to hematocrit levels, erythrocyte parameters in this cohort did not appear to have any relation to the severity of chronic lung disease in patients.

At admission, five patients had a history of phlebotomy and hematocrits were located preferentially in the last interquartile or near this range. On the other hand, the presence of the exacerbation did not differ according to the Anthonisen criteria, but did show a trend to greater affectation of oxygenation and hypercapnia in the presence of higher hematocrit levels.


Spleen sizing by ultrasound in polycythaemia and thrombocythaemia: The acute and chronic effects of phlebotomy on general hemodynamics and pulmonary functions of patients with secondary polycythemia associated with pulmonary emphysema.

Use of long-acting anticholinergic. It is also probable that there were cases of patients with exacerbation who died during hours not available for sample collection and, therefore, could not be included.

There are limited data on its usefulness, as there are no works on proper methodology to evaluate its effectiveness Am J Hematol ; To define the entry of each individual to the study, the patient or caregiver was asked to sign an informed consent during the initial interview for authorization to collect data, accessing medical records, follow-up at 30 days and processing the information obtained.

The selection of the cohort was done in order to determine prognostic factors tratqmiento 30 days of admission related to hospital stay, need for mechanical ventilation, need for transfer to intensive care unit ICU trtaamiento, rehospitalization and death.

Eritroccitosis, an angiotensin II type 1 receptor antagonist, lowers hematocrit in posttransplant erythrocytosis. Survival on long-term oxygen therapy in chronic airflow limitation: The outcome variable was a composite between death, length of hospital stay in floors, need for invasive or non-invasive ventilatory support, need to transfer to ICU and rehospitalization, provided that they were associated with chronic lung disease.

The prognostic value of this variable in the exacerbation has not been evaluated to date. In-hospital mortality following acute exacerbations of chronic obstructive pulmonary disease.

Adverse outcomes were more likely to occur at the extremes of the distribution of hematocrit values, also with longer hospital stay when hematocrit values were lower. The survey was completed by telephone at 30 days after admission to hospital in order to assess the rratamiento.

For this, oxygen saturation was chosen considering the dissociation curve of hemoglobin and the values of red blood cell parameters of studies that have determined normal values in high altitudes 18, Effects on pulmonary hemodynamics, gas exchange, and exercise capacity.
