Introduction:
Most traumatic lung injuries are managed non-operatively. There is a paucity of recent data on the outcomes of operatively managed lung injuries. The aim of our study is to determine the survival rates of operatively managed traumatic lung injury patients on a nationwide scale.
Methods:
We performed a retrospective analysis of the ACS-TQIP 2017-2020. We included all adult trauma patients with lung injuries that underwent operative management. Patients were stratified based on type of surgery into 3 groups (wedge resection, lobectomy, pneumonectomy). The outcome was mortality. Multivariable logistic regression analysis was performed to identify the independent predictors of mortality.
Results:
We identified a total of 170,377 patients with lung injuries, out of which 2159 (1.3%) patients underwent operative management (Wedge resection [61%], Lobectomy [31%], Pneumonectomy [8%]). Among operatively managed patients, the mean (SD) age was 37 (16) years, and 86% were male. Overall, 65% sustained penetrating injuries, with a median [IQR] ISS of 25 [16 - 33], and median [IQR] lung injury AIS severity of 4 [3 - 4]. About 7% of the patients suffered hilar injuries. The mean (SD) SBP on arrival was 108 (43) and the median [IQR] time to surgery was 177 [52 - 5351] minutes. The median hospital LOS was 10 [1 - 19] days, and overall mortality rate was 30%. On univariate analysis, patients undergoing pneumonectomy had the highest mortality (54%), followed by lobectomy (33%), and wedge resection (25%). On multivariable regression analysis, hilar injuries (aOR 1.9, 95%CI = 1.06 - 2.80, P = 0.029), increasing age (aOR 1.02, 95%CI = 1.01 - 1.03, P = 0.001), concomitant head (aOR 1.34, 95%CI = 1.22 - 1.47, P < 0.001) and abdominal injuries (aOR 1.42, 95%CI = 1.31 - 1.54, P < 0.001) were independent predictors of mortality.
Conclusions:
Nearly 1 in 3 patients with lung injuries who were managed operatively did not survive their index admission. These findings highlight that operatively managed lung injuries still carry a high risk of mortality and should be reserved for selected patients. The decision for surgery in patients with concomitant head or abdominal injuries must be taken on a case-to-case basis.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
