"Phlebotomy decreases blood volume and viscosity, increases cardiac
output and
improves exercise tolerance in patients"
"Improvement was dramatic"
Phlebotomy for rapid weaning and extubation in COPD patient with
secondary polycythemia and respiratory failure.

Abstract
The increased incidence of ventilator-associated complications in
patients
with chronic obstructive pulmonary disease (COPD) necessitates rapid
weaning and extubation.
The presence of secondary polycythemia in this subgroup increases the
incidence of stroke and myocardial infarction due to hyperviscosity
and
tissue hypoxia.
We present a 58-year-old male patient of COPD with secondary
polycythemia
(hematocrit 64%) who had possible hyperviscosity-related complications
leading
to cardiac arrest after a minor surgical procedure.
The patient developed ventilator dependence after recovery.
Phlebotomy was done to remove 10% of total blood volume.
Symptomatic improvement was dramatic.
Improvement in weaning indices like rapid shallow breathing index and
PaO(2)/PAO(2) was observed facilitating rapid weaning and early
extubation.
Monitored, acute phlebotomy is safe and cost-effective.
It decreases blood volume and viscosity, increases cardiac output and
improves exercise tolerance in patients.

Half of COPD Patients Were Misdiagnosed as Having Asthma
70% of those with this leading cause of disability are senior
citizens.
COPD (chronic obstructive pulmonary disease) - a progressive
condition
that leads to a worsening of respiratory symptoms, a decline in lung
function and increased disability - tends to be under-diagnosed and
under-treated. More than half of patients with COPD, for example, may
be misdiagnosed as having asthma. Estimates are that almost
three-fourths of COPD patients are senior citizens.
The new study results, published in the Journal of Asthma, are from
the
most recent prospective, patient-reported, objectively documented
COPD
study to examine COPD misdiagnosis.
COPD, which includes chronic bronchitis and emphysema, is
characterized
by a loss of lung function over time.(2) Primarily a disease of
current
and former smokers, COPD affects nearly 12 million Americans.(3)
Unlike
asthma, COPD is associated with a cascade of decline that leads to a
diminished quality of life over time.(7)
Most people with COPD are at least 40 years old or around middle age
when symptoms start. It is unusual, but possible, for people younger
than 40 years of age to have COPD.
"Millions of people live with COPD for years, so their inability to
do
the things they enjoy because they simply can't breathe is
devastating," said the study's lead author, David G. Tinkelman, M.D.,
Vice President for Health Initiatives, National Jewish Medical and
Research Center, Denver.
"We need to clarify the differences between COPD and asthma so
patients
get the right diagnosis early and the appropriate interventions
needed
to change the course of this growing health crisis."
The study, conducted in Denver and Aberdeen, Scotland, and sponsored
by
Boehringer Ingelheim Pharmaceuticals, Inc. and Pfizer Inc, analyzed
data from 597 patients age 40 and older with a history of lung
disease
or recent treatment with respiratory medications.(1) Patients were
then
screened using spirometry, a lung function test, to confirm their
diagnosis of COPD.(1)
In this study, a COPD diagnosis was defined in agreement with
American
Thoracic Society and European Respiratory Society guidelines as the
presence of obstruction -- inability to get air out of the lungs --
based on spirometry results.(1)
Of the 235 patients diagnosed with COPD by spirometry (measuring the
capacity of the lungs), 51.5 percent reported a prior diagnosis of
asthma only.(1) Only 37.9 percent of participants diagnosed with COPD
based on the study tests reported a previous diagnosis of the
disease,(1) while 10.6 percent reported no prior diagnosis of COPD or
asthma.(1)
"These findings are surprising given the availability of credible
diagnosis and treatment guidelines specifically for COPD," noted Dr.
Tinkelman. "Only through proper diagnosis and treatment will COPD
patients fully benefit. Patients can benefit from lifestyle
modifications, pulmonary rehabilitation and proper pharmaco therapy
that may help them breathe better and return to the activities they
enjoy."
About COPD
COPD is second-leading cause of disability (5) and the fourth-leading
cause of death in the U.S.(2) While COPD is primarily caused by
cigarette smoking, other causes of COPD include exposure to
occupational dusts and chemicals.(2) Researchers have also found a
link
between COPD and a rare genetic disorder involving a deficiency in
the
enzyme alpha1-antitrypsin (AAT) that normally prevents loss of
elasticity in the lungs' fibers.(7)
The most common COPD symptoms include shortness of breath, chronic
cough (sometimes with phlegm), and wheezing.(2) In mild COPD,
patients
experience breathlessness during high-energy activities, such as
exercise.(4) As the disease worsens to the moderate and severe
stages,
patients become breathless more frequently, avoiding activities that
cause shortness of breath.(4) This can lead to physical
deconditioning
-- loss of muscle strength -- and disability.(4) Patients eventually
become breathless, even at rest.
COPD accounts for a high proportion of health-care costs -- nearly
$40
billion in the U.S.(8) In the last 20 years, COPD was also
responsible
for nearly 50 million hospital visits nationwide.(9)
COPD is, however, a manageable disease.(7) According to diagnosis and
treatment guidelines set by the Global Initiative for Chronic
Obstructive Lung Disease (GOLD), intervention can help improve and
prevent some of the symptoms of COPD and improve health status and
patient outcomes.(7)
