Diagnosis and Treatment of Thoracic Conditions: A Comprehensive Review

I- Dx and T of Spontaneous Pnthorax:



^DX :


I- Dyspnea, pleuritic chest
Pain / ↓  Breath Sounds/Hyperesonance!
II-XRay on Inspiration:
-Radiolucent air & absence of MAaking between
 a shrunken lobe or lung
&the parietal pleura are diagnositc of Pneumothorax!
-Tracheal deviation , 
III-  Pnthroax Defined:% of empty hemithorax


^^Tension Pn thorax :


if there is suden & unexplained :
-hypotension
-Dyspnea
-+ve Pressure ventilation



^^Tx:



I-”TENSION Pn TRX=Needle Decompresion

– ER —-> cannot wait for XRay 
– Needle —–> 2nd IC space at mid-clavicular level!



II-‘1o Spont Pnthorax”=Catheter Aspiration

-Small bore IV —-> 2nd IC space ,mid lcaviular
-Air is withdawn from pleural space
-Process is repeated until Lung Re-expands  or 4 L of air remvoed



III-”2nd  & Traumatic Pnthorax”=Tube thoraccostomy:


-1/2 HEmotact/ Kelly Clamps 
-Inserted Tube—-> 4th IC space , midaxillary line
-Using advanging Hemosat or kelly lamp the Pleura is dissected,
 pleura is then pergorated 
-clamp is inseeed through the tract and directly apical to Pnthoax



IV- Thoracosoy:


-Rigid telescope & insturment inserted into the pleiral space ,
 through the trocar under local anasthesia
-1/2 tubes are left in the pleural space


V- VATS (Video assisted thoracic surgery):


-Under general ansthesia
– operated side should be isolated & its bronchial tree exposed
 to outside atmopsere
-VATS beigns with insertion  of a trocar camera and exploraton fo hemithrax later
-Principles of Surgery is :Resecting blebs, nbullae,  
Obliteration of pleural space





(2)*** Surgical Approach in  Tx of pleural empysema : irrigatie -aspirativ drainage ….:


Blood in pleura Sac

Primary Pleural empyema


– bacterial contamination of pleural space due to chest Trauma
Secondary pleural empyema
-Direct contamination from organs adjacent to pleural surface
-direct bacteria spread across the visceral or parietal pleura
90


^^Bacterial Classication:



-non speicif/pyogenic


-Specific


-Mixed


Complicated, Lined with bronchopleual/alvoelar fistula


Non complicated



^^Surgical proceudre foe empyema:


I-Irrigation & Drainage:– Acute & chronic Non compicated Pleural empyema to facilitation elimation of peural content-Caution is adviced in presence of Bronchopleural Fistula  
de to possible aspiration with washing Fluid
II-Decortication and pleuretony -In Case of chronic pleural empyema!
-Decortication:-—–>removal of constricting Peel from the Lung
-Pleurectomy—->excision of thickened parietal pleura
-Goal: of these procedure is Lungreexpansion
III-Pleurostoma:-in patient whose lung can re-expand and his condition is stable-Pulmonary Decortication  alternative-Involves resecting 6-20 cm  of 2-4 ribs
   —–>creating large defect in patient chest




(3) *** Classification of Chest Trauma :


Penetrating ChT(Isolated /Polytrauma)


-Superficial Wound (Chest Wall)
-Involving the parietal pleura & intrathoracic viscera

Blunt ChT(Isolated/Polytrauma)


-Non complicated chest wall injury
( Contusion / hematoma/ Chest bone fracture)
-Complicated Facture of chest Bone
-Blunt Injuries of intrathoracic viscera
(Pleruopulmonary/CVS.Rupture of esophagus/Diaphragm rupture)
(4) *** Syndrome of Chest Trauma :
^^Gaseous Syndrome 
(air —-> into soft tissue of Chest Wall ,mediastinum & Pleural Space)

I-Subcutaneous Emphysema


II-Pneumothorax

-Air in pleural cavity
-minimal= no lung compression
-Moderate=Lung collapse
-Total= compression and displacement of Mediastinum

III-Pneumomediastinum

-Maybe due to esophageal perforation
-Degree caries with location
-Air reaches Visceral pleura

IV- Intersitial Pulmonary emphysema

-Air penetrates into pulmonary parenchyma dissecting
 into along the vessel and small bronchi
-blebs occur when air reaches Pleura

^^Open Pneumothorax:


-Penetrating Wound /Defect in chest wall
-Result : intrapleural = atm

^^Flail chest:


-2 pint fracture of Several Ribs or sternum
-paradoxical movement of segment of chest
-Alters ventilation and result in hypoxemia or Hypercapnia

^^Traumatic Asphyxia

-Cause:
Crush injury or sidden compression 
-Rise n intrathoacic pressre,intrathoracic Venous Pressure
, stopping or reversing venous Drainage(head and neck)
^^Pulmonary contusion & hematoma:
^^Hemothroax
(Blood accumilation in pleural cavity )
