Conservative Management May Be Appropriate for Small CT-Diagnosed Hemothorax: Study
A new study published in the journal of Injury showed that if clinically stable, individuals with a CT-diagnosed hemothorax of less than 300 cc (pleural thickness <15 mm) may frequently be treated conservatively.
Hemothorax, or the buildup of blood in the pleural cavity, is a common consequence of chest trauma. Traditionally, chest tubes had to be inserted right away as part of routine therapy. However, tiny, clinically occult hemothoraces that are not apparent on normal X-rays are frequently discovered as a result of the common use of computed tomography (CT) in contemporary trauma care.
So, conservative treatment which relies on careful clinical monitoring without tube thoracostomy has become a practical substitute. To improve trauma procedures, lower needless procedural risks, and guarantee patient safety, it is essential to assess the clinical results, success rates, and possible consequences of this non-operative technique. The study assessed the outcomes and consequences of conservative therapy in patients with a small-volume hemothorax.
PRISMA principles were adhered to in this meta-analysis and systematic review. CT-diagnosed traumatic hemothorax in stable patients receiving conservative treatment was searched in PubMed, Scopus, and the Cochrane Library. Articles that satisfied the requirements for inclusion were examined. The failure rate of conservative management was the primary result that was measured.
Ten studies that reported on 3030 patients with hemothorax identified by CT satisfied the inclusion criteria out of the 3089 papers that were evaluated.
Of them, 1679 patients (55.4%) received conservative care, with an 81% success rate.
A hemothorax volume of less than 300 cc was seen in the majority of cases (94.4%), and 409 individuals also had an undetected pneumothorax.
Of patients under conservative care, 19% (319/1679) needed a delayed tube thoracostomy; just 1.8% needed further surgery.
The development of respiratory distress (12.3%), worsening pneumothorax (16.4%), and hemothorax progression on follow-up chest x-ray (62.0%) were the main reasons for a delayed tube thoracostomy.
Thoracic injuries had no bearing on any of the reported deaths.
Overall, one in five patients with CT-diagnosed hemothoraces less than 300 cc (thickness less than 15 mm) can be treated conservatively. These findings emphasize the necessity for close observation and consistent procedures while also supporting observation in stable patients.
