Background:
Serious blunt chest trauma usually induces hemothorax, pneumothorax, and rib fracture. Early video-assisted thoracoscopic surgery (VATS) to evacuate retained hemothorax is one commonly used treatment. In this study, a new strategy was implemented to combine VATS with fractured rib fixation simultaneously.
Methods:
This prospective observational study was performed from January 2013 to April 2018. All patients were aged 18 years or older and had blunt chest trauma with displaced fractures in more than three ribs. No patients had acute respiratory failure within 24 h after trauma. Patients with retained hemothorax who received VATS constituted the study cohort. Subsequently, patients who received rib fixation during VATS procedures were compared with those who did not. Clinical outcomes such as dose of analgesics, and length of hospital stay were recorded.
Results:
During the study period, 128 patients were enrolled. Available demographic characteristics of the 2 groups were compared, and no statistical differences were observed. The rates of shorter temporary ventilator dependence after operations were lower in the rib fixation group (0% vs. 24.7%, P = 0.017). Persistent air leakage more than 5 days after operations were also lower in the rib fixation group (0% vs. 10.4%, P = 0.001). The length of stay in overall hospital stay were longer for patients who received VATS without rib fixation (9.29 ± 2.51 days vs. 12.39 ± 4.65, P = 0.001). Furthermore, the rib fixation group were administered much lower doses of opiates during their hospital stays (52.45 ± 15.67 mg vs. 77.24 ± 50.42 mg, P = 0.001).
Conclusion:
Adding rib fixation during VATS in the management of retained hemothorax can contribute to shorten whole treatment courses. Rib fixation can also reduce pain, thus reducing dependence on analgesics.

Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
