exam 3 lung absess ca Flashcards
Common causes of lung absesses
aspiration
TB
Fungal infections
Hx pneumonia, aspiration, obstruction
Common causes of empyema
infection
lung abscess
infected pleural effusion
S/S of lung abscess
pleuric chest pain temp pale, fatigue, night sweats, foul sputum odor dullness on chest percussion crackles often over lesion pleural friction rub
S/S of emphyema
pleuritic chest pain & friction rub decrease lung sounds
dyspnea, uneven chest expasion
plerual effusion
foul smelling sputum
compression of lung tissue near effusion
anorexia, night sweats
What are the most common organisms for lung abscess
from alcohol induced aspiration
gingivitis
streptococci and staphylococci—sometimes methicillin-resistant Staphylococcus aureus (MRSA)
lung abscess
a necrotizing lung infection characterized by a pus-filled cavitary lesion
Pneumonectomy
Removal of the whole lung b/c ca, brochiectasis, lung abscesses, extensive tb.
Removal of the right is worse bc right lung has larger vascular bed & poses more risk
Lobectomy
Removal of lobe of lung.
More common
Segmentectomy
Removal of segment of lobe is removed
Wedge
Resection of A small well circumscribed lesion
Plural cavity is drained bc of poss air or bld leak. Performed for lung biopsy and for excision of small perhiral nodules
Post op care after thoracic surgery
Vitals, o2 , hob 30-45, pnuemo- turn 1h back to operative side, lobe- turn either side,
Meds, splint chest, is, check chest tubes & drainage
Managing chest tubes
If it comes unplugged- put gauze cover connection come apart put back to gether bottle breaks, submerge it in water bubbling-air in, vigourous--leak small, gentle buble-ok fluid tidling-ok, normal if it stops tidling the lung has re expanded, someone stepped on it, turn off suction, theres a clot, if its hanging low & coiled. carry it below gravity do not milk strip tubing ever tdbc assess bottle, drainage draw a line with time date and initials little bld ok green, yellow infection- should be clear Good body alignment with turning q1.5-2
S/s to report immediately with chest tubes
Rapid, shallow breath Cyanosis Press in chest Sucq empyema Sx of hemorrhage Change in vitals
When the wall vacuum is turned off…
The drainage system must be open to atmosphere so that intramural air can escape the system. This is done by detaching tubing from suction port to provide a vent.m
If chest tube comes apart from drainage system…
Pneumo can occur, to prevent place tubing in a container of sterile water.
