RESUMEN
Background The insertion and subsequent removal of chest tubes are frequently performed procedures for the management of pneumothoraces, pleural effusions, and cardio-thoracic surgical interventions. A chest radiograph is commonly obtained after the removal of a chest tube to rule out the interval development of a pneumothorax. This practice has been questioned in various retrospective and prospective studies conducted on surgical patient populations, showing little to no benefits in performing routine chest X-rays (CXRs) after chest tube removal unless clinical symptoms such as worsening respiratory status and hemodynamic compromise are present. Material and Methods A four-year retrospective study was conducted using the Cleveland Clinic Foundation database. A chart review was performed, and 1,032 patients were screened, with 200 patients meeting inclusion criteria. The inclusion criteria included patients who underwent chest tube insertion for non-surgical reasons. The primary outcome was the percentage of clinically significant pneumothoraces detected by routine CXR after chest tube removal. Results Out of the 200 patients included in the study, 53 had a CXR after chest tube removal showing a residual pneumothorax. Out of the 53 patients, 50 ended up not needing chest tube re-insertion, as the patients were asymptomatic and hemodynamically stable. Only three patients required chest tube re-insertion due to respiratory symptoms and significant hemodynamic changes after the chest tubes were removed. In all three cases, the symptoms manifested prior to the CXRs being obtained; therefore, the decision to reinsert each chest tubes was made based on clinical signs rather than imaging. As expected, the practice of repeating CXRs after removal of the chest tubes resulted in delayed discharges despite patients reporting no symptoms and being hemodynamically stable. Conclusions Our study findings correlate with prior smaller studies on surgical patients. Symptoms and hemodynamic data seem to be a better predictor of whether a patient will require chest tube re-insertion or not. Routine CXR after chest tube removal also leads to prolonged hospital stay.
RESUMEN
BACKGROUND: Systemic sclerosis is a chronic debilitating autoimmune disease characterized by endothelial dysfunction and multi-organ fibrosis. Interstitial lung disease, a common manifestation of SSc, is termed scleroderma-related interstitial lung disease (SSc-ILD) and along with pulmonary hypertension contributes to a majority of deaths in SSc. SSc-ILD patients frequently develop pulmonary hypertension, which prognosticates a poorer outcome. We investigated pulmonary artery dimensions as an outcome predictor in patients with SSc-ILD. METHODS: A retrospective chart review abstracting data from SSc-ILD patients evaluated at a large tertiary care center was performed. HRCT imaging was reviewed and pulmonary artery (PA) and ascending aorta (Ao) diameters were measured for calculation of the PA:Ao ratio. Additionally, demographics, vital signs, spirometric parameters, comorbidities, and mean pulmonary artery pressures were collected when available. Outcome analysis with lung transplant or death events within 4 years based on pulmonary artery size as well as PA:Ao ratio was performed. RESULTS: 70 SSc-ILD patients were identified. Mean pulmonary artery diameter and PA:Ao ratio was 31.17 and 1.07 mm, respectively. Patients with a pulmonary artery diameter ≥32 mm had higher risk of lung transplantation or death (p < 0.001) within 4 years. Patients with a PA:Ao ratio ≥1.1 also had higher risk of lung transplantation or death (p < 0.001) within 4 years. Unadjusted outcomes analyses also identified PA:Ao ratio ≥1.1 as an independent outcome predictor (hazard ratio 3.30, p < 0.001). CONCLUSIONS/CLINICAL IMPLICATIONS: In SSc-ILD patients, a PA:Ao ratio ≥1.1 is associated with higher risk of lung transplant or death. These data suggest that PA:Ao dimension may be used for prognostication in SSc-ILD.
