Chapter 63: Hemoptysis Flashcards
What is the definition of massive hemoptysis?
100 - 1000ml per 24 hours. with midpoint of 600ml
What is the definition of minor hemoptysis?
self limited, small volume expectoration of blodd in a patient with no comorbid lung disease an stable vital signs
What type of artery is the most common cause of hemoptysis?
bronchial arteries because it is high pressure system. at the same time accounts for 1% of the blood flow to the lungs
Where is the origin of bronchial artery?
from thoracic aorta at level of T5 - T6
Most common causes of potentially massive hemoptysis?
parenchymal origin (TB, mycetoma, neoplasm and bronchiectasis)
How the COPD patient have hemoptysis?
in COPD patient neogenesis stimulated to increase blood to alveoli and this new vessels in fragile which produce hemoptysis
What is Rasmussens’s aneurysm
a false aneurysm of dilated blood vessels crossing the wall of a tuberculosis cavity
What pulmonary carcinoma accouts for massive hemoptysis
squamous cell carcinoma
A disease manifest in friable telangiectasis compromised of pulmonary vessel arteriovenous malformations in the lungs and other organ
Osle-Weber-Rendu disease
Patient with hemoptysis presented with hematuria and renal insufficiency
goodpasture’s syndrome or granulomatosis with polyangiitis (saddle nose)
Associted with hemoptysis and hydatic cyst within the lungs
Echinococcosis species
If patient with hemoptysis has normal hemoglobin. when can you repeat cbcpc for accurate measurement of hgb?
after 6 hours
This increase mortality in patient with massive hemoptysis
thrombocytopenia and coagulopathy
This shows scattered alveolar infiltrates on chest radiograph
diffuse alveolar hemorrhage
This shows infiltrates, masses and cavitation
focal alveolar hemorrhage
