Qhov Tseem Ceeb Qhov txawv - Lobar Pneumonia vs Bronchopneumonia
Kev cuam tshuam ntawm lub ntsws parenchyma los ntawm tus kab mob ua rau tus neeg sawv cev (feem ntau yog cov kab mob) evokes exudative solidification ntawm (sib sau ua ke) ntawm cov ntaub so ntswg pulmonary hu ua mob ntsws. Raws li lub zos ntawm cov inflammatory foci, pneumonia muab faib ua ob lub ntsiab subcategories li lobar pneumonia thiab bronchopneumonia. Thaum tus kab mob no tsuas yog ib lossis ob peb lub lobes ntawm lub ntsws uas hu ua lobar pneumonia. Ntawm qhov tod tes, bronchopneumonia yog qhov mob ntawm lub ntsws parenchyma uas tshwm sim los ntawm bronchi lossis bronchioles thib ob mus rau tus kab mob. Raws li, qhov sib txawv tseem ceeb ntawm ob hom yog tias nyob rau hauv lobar pneumonia, qhov mob yog nyob rau hauv ib lub lobe tab sis nyob rau hauv bronchopneumonia inflammatory foci muaj nyob thoob plaws hauv lub ntsws yam tsis muaj chaw nyob.
Pneumonia yog dab tsi?
Kev cuam tshuam ntawm lub ntsws parenchyma los ntawm tus kab mob ua rau cov kab mob, feem ntau cov kab mob evokes exudative solidification ntawm cov ntaub so ntswg pulmonary hu ua pneumonia.
Kev faib cov kab mob ntsws yog nyob ntawm ntau yam.
Nrog kev cuam tshuam rau tus neeg sawv cev-Bacterial, viral, fungal
- Nrog kev sib raug zoo rau tag nrho cov kev faib tawm ntawm tus kab mob-Lobar Pneumonia, Bronchopneumonia
- Nrog rau qhov chaw uas mob ntsws kis tau-Cov zej zog-tau txais, tsev kho mob-tau txais
- Nrog kev sib raug zoo ntawm tus tswv tsev cov tshuaj tiv thaiv-Suppurative, fibrinous
Pathogenesis
Lub ntsws ib txwm tsis muaj kab mob ua rau muaj kab mob lossis tshuaj. Cov kab mob ua pa muaj ntau yam kev tiv thaiv los tiv thaiv kev nkag mus ntawm cov kab mob no.
- Nasal clearance – particles deposited in front of the airway on the non-ciliated epithelium is nquag tshem tawm los ntawm txham lossis hnoos. Cov khoom uas muab tso rau tom qab raug cheb hla thiab yuav nqos.
- Tracheobronchial clearance- qhov no yog nrog los ntawm mucociliary action
- Alveolar clearance- phagocytosis los ntawm alveolar macrophages.
Mob ntsws tuaj yeem tshwm sim thaum twg cov kev tiv thaiv no tsis zoo, lossis tus tswv tsev tsis kam txo. Cov yam ntxwv xws li cov kab mob ntev, kev tiv thaiv kev tiv thaiv kab mob thiab kev siv tshuaj tiv thaiv kab mob, leukopenia, thiab kab mob kis tau cuam tshuam rau tus tswv tsev tiv thaiv ua rau tus tswv tsev muaj kev cuam tshuam los ntawm cov kab mob no.
Lub tshuab tshem tawm tuaj yeem raug puas tsuaj ntau txoj hauv kev,
Txhob hnoos reflex thiab txham reflex
Secondary to coma, anesthesia or neuromuscular disease.
Kev raug mob rau mucociliary apparatus
Kev haus luam yeeb ntev yog qhov laj thawj tseem ceeb rau kev puas tsuaj ntawm cov mucociliary apparatus.
- Kev cuam tshuam nrog phagocytic action
- Pulmonary congestion thiab edema
- Kev sib sau ntawm cov qog pulmonary hauv cov xwm txheej xws li cystic fibrosis thiab bronchial obstruction.
Lobar Pneumonia yog dab tsi?
Thaum tus kab mob no tsuas yog ib lossis ob peb lub ntsws ntawm lub ntsws uas hu ua lobar pneumonia. Cov kab mob tseem ceeb yog pneumococci, klebsiella, staphylococci, streptococci.
Morphology
Plaub theem ntawm cov lus teb inflammatory tau piav qhia.
Lub ntsws hnyav, boggy, thiab liab. Qhov theem no yog qhov tshwm sim ntawm vascular engorgement, intra -alveolar kua nrog ob peb neutrophils, thiab feem ntau muaj ntau cov kab mob.
Red hepatization
Congestion yog ua raws li cov kab mob siab liab uas tshwm sim los ntawm cov exudation loj heev nrog cov hlwb liab, neutrophils, thiab fibrin sau cov chaw alveolar.
Grey hepatization
Nyob rau theem grey hepatization vim yog qhov kev tawg zuj zus ntawm cov qe ntshav liab uas tau sau rau hauv qhov chaw alveolar, lub ntsws xav tias muaj xim grey. Qhov no greyish tsos yog txhim kho los ntawm lub xub ntiag ntawm fibrino suppurative exudate.
Resolution
Thaum lub sijhawm kawg ntawm kev tsim cov kab mob, cov exudate sib sau ua ke hauv cov chaw alveolar tau dhau los ua kev zom zaub mov kom tsim cov pob zeb ib nrab ntawm cov kua dej uas tau rov ua dua thiab noj los ntawm macrophages lossis hnoos.
Kev nyuaj siab
- Abscess - vim yog cov ntaub so ntswg puas thiab necrosis
- Empyema- vim qhov kis tau kis mus rau hauv cov kab noj hniav pleural
- Organization
- Kev tawm mus rau hauv cov hlab ntsha.
Tshuaj Kho Mob
- Dyspnea
- Cov hnoos qeev
- fwb
- Pleural kev sib txhuam rub
- mob plab
Kev tshawb nrhiav
- X-ray qhia txog thaj chaw ntawm kev sib sau ua ke thiab tuaj yeem muab cov lus qhia muaj txiaj ntsig los txheeb xyuas tus neeg sawv cev ua rau.
- Ntsuab rau kab lis kev cai thiab gram staining
- Bronchoscopy tuaj yeem ua tau thaum muaj kev mob qog noj ntshav lossis muaj kev cuam tshuam hauv lub ntsws.

Kev tswj hwm
Kev kho tshuaj tua kab mob empirical tuaj yeem pib tom qab noj cov qauv rau kev tshawb xyuas. Cov tshuaj tua kab mob uas tau sau tseg yuav raug hloov pauv thaum muaj kev sim tshuaj tua kab mob rhiab heev thiab kab lis kev cai muaj. Kev ua pa yuav tsum tau muab rau cov neeg mob uas ua tsis taus pa hnyav.
Bronchopneumonia yog dab tsi?
Bronchopneumonia yog qhov mob ntawm lub ntsws parenchyma uas tshwm sim los ntawm bronchi lossis bronchioles thib ob mus rau tus kab mob. Staphylococci, Streptococci, Pneumococci, Haemophilus, thiab Pseudomonas auregenosa yog cov kab mob tseem ceeb.

Morphology
Foci ntawm bronchopneumonia yog cov chaw sib koom ua ke ntawm kev mob suppurative mob. Kev sib sau ua ke tuaj yeem ua rau thaj tsam ntawm ib lub lobe tab sis feem ntau yog multilobar thiab feem ntau ob sab
Dab tsi zoo sib xws ntawm Lobar Pneumonia thiab Bronchopneumonia?
- Ob qho xwm txheej yog vim qhov mob ntawm pulmonary parenchyma thib ob mus rau tus kab mob.
- Cov yam ntxwv kho mob, kev tshawb nrhiav tau ua thiab kev tswj hwm ntawm ob qho tib si tib yam.
