Successful closure of a bronchopleural fistula by intrapleural administration of fibrin sealant: a case report with review of literature.

CONTEXT: There are no established guidelines for the proper treatment of patients with bronchopleural fistulas (BPFs). Apart from attempts to close the fistula, emphasis of treatment and management is placed on preventive measures, early administration of antibiotics, drainage of the empyema and aggressive nutritional and rehabilitative support. CASE REPORT: A 53-year-old male presented with nausea, vomiting, and dry cough with eventual respiratory failure. He was found to have an empyema of the left hemithorax which was managed with thoracostomy drainage and antibiotics. However, he had persistent air leak through the chest tube due to a BPF. Bronchoscopy failed to localize the involved segment. Application of fibrin glue through the chest tube succeeded in completely sealing the leak. CONCLUSION: To our knowledge, this is the first case report in which fibrin glue was successfully used intrapleurally to close a BPF related to an empyema.

An atypical case of right-sided bochdalek hernia in an adult.

Bochdalek hernias are usually congenital in nature and normally present after birth. However, in rare cases, these hernias are present in adulthood. We report an unusual case of a posttraumatic right-sided Bochdalek hernia found incidentally in an adult and treated successfully with conservative management.

Association of hypophosphatemia with failure-to-wean from mechanical ventilation.

Severe hypophosphatemia is known to be associated with respiratory failure, but there are few studies that specifically examine the relationship between serum phosphorus concentration and failure to wean patients from mechanical ventilation. This study investigated the association between hypophosphatemia and weaning failure in patients in two medical intensive care units (ICU). The study was conducted in a prospectively developed cohort of 66 patients being treated with ventilatory support and in whom 193 weaning trials were attempted. Ultimately, all 66 subjects were successfully weaned. A cross-sectional analysis was conducted on serum phosphorus levels and success or failure to wean the patients from ventilators. At the time of the successful weaning attempts (n = 66), the subjects' serum phosphorus concentrations (mean +/- SD) were 1.18 +/- 0.27 mmol/L, whereas at all failed weaning attempts (n = 127) serum phosphorus concentrations averaged 1.06 +/- 0.31 mmol/L (p = 0.008). Subjects with phosphorus concentrations below the reference interval (RI) in our laboratory (<0.80 mmol/L) had greater risk for weaning failure compared to subjects with phosphorus concentrations at or above the RI (relative risk = 1.18; 95% confidence interval = 1.06 to 1.32; p = 0.01). Serum calcium concentrations were not significantly different at the time of successful weaning compared to those at failed weaning attempts. This study indicates that there is an association between hypophosphatemia and failure-to-wean from mechanical ventilation in ICU patients on ventilatory support.
