A 42-year-old woman was hospitalized with fever and hypoxemia. The workup for fever was unrevealing. A computed tomographic scan of the chest showed centrilobular, small, nodular opacities throughout both the lung fields. A flexible bronchoscopy with transbronchial biopsy was performed. Pathology specimens consisted of intravascular foreign material with birefringent properties suggestive of microcrystalline cellulose. It was later determined that the patient was self-injecting herself with crushed pill fragments through a tunneled central venous catheter. The central venous catheter was removed and fever resolved.
Several studies have demonstrated the diagnostic yield of medical thoracoscopy (pleuroscopy) in making the diagnosis of malignant pleural effusion (MPE). No previous studies, however, have reported long-term outcomes for patients undergoing diagnostic pleuroscopy in whom no malignancy was demonstrated either with cytologic examination of pleural fluid or pathologic examination of thoracoscope-guided pleural biopsies. We report the results of long-term follow-up (at least 3 y) of patients with the diagnosis of nonmalignant pleural effusions (NMPEs) after pleuroscopy.One hundred and nineteen patients underwent the procedure between 1994 and 2003 at Lahey Clinic. We report a retrospective review of 25 of those patients diagnosed with NMPE after diagnostic pleuroscopy. All 25 patients underwent thoracoscopic pleural biopsy and cytologic examination of the effusion. Outcomes were assessed using review of the medical records, appointment scheduler, social security death index, and/or telephone conversation with primary care providers.Mean age±SD was 68 years (range, 34 to 87 y). Median survival time was estimated at 114 months. Concomitant illness was also evaluated: 40% (n=10) diabetes, 64% (n=16) coronary artery disease, 40% (n=10) congestive heart failure, 20% (n=5) liver disease, 20% (n=5) renal disease, and 36% (n=9) pulmonary disease. Final diagnoses after pleuroscopy most commonly included chronic pleuritis (n=7) and pleural plaques (n=5). Survival was found at 1 year to be 88% (22/25), 3 years 80% (20/25), and 5 years 74.7% (19/25). None of the 25 patients developed subsequent MPE.Patients with NMPE after pleuroscopy have a favorable prognosis and are unlikely to be subsequently diagnosed with an MPE.
Background: A case-control study was conducted to identify the possible risk factors for acute respiratory failure in patients undergoing bronchoscopy. We also aimed to estimate the financial costs incurred in the care of high-risk patients. Methods: All hypoxic respiratory complications that occurred during bronchoscopy between January 2005 and March 2009 were reviewed. Mild hypoxia was defined as the need for up to 6 L of nasal cannula, moderate hypoxia as requiring up to 100% nonrebreather face mask, and severe hypoxia requiring intubation and mechanical ventilation to maintain pulse oximetry above 90%. The Wilcoxon 2-sample test was used to compare continuous groups. Categorical variables were assessed using χ2, Fischer exact, and Kruskal-Wallis tests. We calculated the cost of medical care for patients admitted to the intensive care unit after bronchoscopy. Results: During our study period, 26 patients were reported to have hypoxia with bronchoscopy. The mean age for our study group was 66.1 years, and body mass index 26.1 kg/m2 (SD, 7.6). The study group’s mean albumin was 2.9 g/dL (SD, 0.6) compared with 3.3 g/dL (SD, 0.7, P=0.0019), the study group’s hematocrit was 32.4% (SD, 5.7) compared with 37.9% (SD, 5.5, P=0.0241), the study group’s forced expiratory volume to forced vital capacity ratio ratio was 65.0 (SD, 15.8) compared with 78.0 (SD, 18.8, P=0.0133), and the study group’s forced expiratory volume was 59.5% compared with 71.2% (P=0.0606). The study group’s mean pCO2 was 53.7 mm Hg (SD, 18.6). Six patients required intensive care unit admission after bronchoscopy and the total cost of care for this group was $80,353. Conclusions: Prescreening of selected patients may reduce respiratory failure and possibly the total cost of medical care.
Percutaneous dilational tracheostomy (PDT) is a commonly performed procedure in any intensive care unit. We hope to provide a concise review of the basic anatomy, technique, indications, contraindications, and complications of PDT. PDT is now a long established procedure for most physicians caring for intensive care unit patients. Not all clinicians will be able to perform the procedure but everyone caring for these patients should be familiar with the technique, indications, and potential adverse effects.
