Occult Pneumothorax• A pneumothorax that is not suspected on the basis of
clinical examination or plain radiography but is ultimately detected with thoraco-abdominal computed tomography.

Objectives
Study conducted both to determine the incidence of OP and describe its current treatment status in blunt trauma population at a Canadian tertiary trauma
center, Of interest were therates of tube thoracostomy vs. observation without
chest drainage and their respective outcome
![Page 6: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/6.jpg)
Methods• Data on all consecutive blunt trauma patients between
October 1994 and March 2003 was reviewed.
• Outcome measures evaluated ;1. Length of stay.2. Discharge status (Dead vs. Alive).3. Intervention and time of intervention (TT and its relation to PPV).
• Direct comparison bet. OP with TT group and OP without TT group… (in terms of baseline characteristics and outcome)

• The natural hx. Of OPTX in blunt trauma pts. at our institution appears to be one of uneventful resolution irrespective of ISS, PPV, or placement of thoracostomy tube.
• The study suggest an interesting hypothesis thatobservation of the blunt trauma patients with OPTX without tube thoracostomy may be safe and contribute to a shorter hospital stay.

Recommendation
These are observations that would benefit from further study in a large, prospective randomized controlled trial.

Objective
To determine which factors predicted failed observation in blunt trauma patients
![Page 13: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/13.jpg)
Methods• Successfully observed patients and patients who failed
observation were compared.
588 OPTX
121( 21% )immediate TT
448( 79% )observed
![Page 14: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/14.jpg)
588 OPTX
121( 21% )immediate TT
448( 79% )observed
27 (6%) failed observation and required TT (1)
Out of 73 pt. on PPV, 10 (14%) failed observation.
Rest did not fail observation
![Page 15: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/15.jpg)
• Hospital and ICU lengths of stay, and ventilator days were longer in the failed observation group.
• OPTX progression and respiratory distress, significant predictors of failed observation.
• No patient who failed observation developed tension PTX, or experienced adverse events by delaying TT.
![Page 16: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/16.jpg)
Conclusion
Most blunt trauma pt. with OPTX can be carefully monitored without TT; however, OPTX progression and
respiratory distress are independently associated with observation failure.

objective
To address the feasibility and safety of randomizing traumatized patients undergoing PPV to drainage or observation.
![Page 20: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/20.jpg)
Methods• Pts. randomized to observation (unless drainage became clinically
indicated) or to chest tube.
• 24 trauma pts. enrolled (2 excluded b/c final CT; no OPTX).
• Episodes of respiratory distress (need for TT, acute/sustained increase in oxygen requirements, difficulty in achieving adequate ventilation and self reported distress) and subsequent imaging abnormalities were recorded until discharge.
![Page 21: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/21.jpg)

Results and Conclusion• Overall respiratory distress, mortality, in hospital days were
similar across groups.
• With no important difference in morbidity, OPTICC trial lays the foundation for future trial comparing drainage or observation in post-traumatic OPTX requiring PPV.

Objective
To identify the incidence of OP using TCT as the gold standard and describes its management amongst Hong Kong Chinese
trauma patients.
![Page 26: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/26.jpg)
Methods• Analysis of prospectively collected trauma registry data.
Consecutive significantly injured trauma patients admitted through ED suffering from blunt chest trauma who underwent TCT between calendar years 2007 and 2008 were included.
![Page 27: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/27.jpg)
36 pts. With at least one OP.
Bilateral OP in 8/36. Total no.
were 44
8/44 had TTAll were
mechanically ventilated in ED
36 pts. Managed
expectantly
No pt. in the expectant group had pneumothorax progression (even though 8 pts. Required subsequent ventilation in the operating room for extrathoracic surgery)
![Page 28: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/28.jpg)
Conclusion
Most OP were managed expectantly without significant complications; no pneumothorax progressed even though
some pts. Were mechanically ventilated.
Incidence of OP in Chinese pt. after blunt trauma is higher than the typically reported in Caucasians.

Objective
To evaluate existing evidence regarding the safety and efficacy of observation as compared to tube
thoracostomy (TT) for management of OPTX in emergency department trauma patients
![Page 32: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/32.jpg)
Methods• Authors searched MEDLINE, EMBASE, the Cochrane Library,
and other databases.
• Inclusion Criteria :studies of adult or pediatric trauma victims at first presentation after blunt or penetrating injury. Randomized to observation or TT. Studies that enrolled pts. On PPV were included.
• Excluded studies :studies that enrolled hemodynamically unstable patients.
![Page 33: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/33.jpg)
• Outcome of interest includes :progression of OPTX, mortality, complications (pneumonia, empyema), and length of stay in hospital and ICU.
• 411 articles identified. After application of inclusion and exclusion criteria, 3 randomized trials enrolling 101 patients were found to have acceptable quality standards suitable for analysis.
![Page 34: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/34.jpg)
Results
Inclusion studies did not reveal any significant difference between observation and TT in regards to progression of OPTX, risk of pneumonia, or length of stay in hospital or ICU.
![Page 35: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/35.jpg)
Conclusion
Existing evidence leads to the conclusion that observation is at least as safe and effective as tube thoracostomy for management of occult pneumothorax.
![Page 36: Presented by : Abdulgadir F. Bugdadi](https://reader036.vdocuments.us/reader036/viewer/2022081604/568166ee550346895ddb4194/html5/thumbnails/36.jpg)
Answer
According to previous studies it appears thatTube Thoracostomy is NOT BETTER than
observation in reducing morbidity and mortality in a blunt trauma patient with occult
pneumothorax.
