Safety of diagnostic flexible bronchoscopy in patients with echocardiographic evidence of pulmonary hypertension
https://www.ncbi.nlm.nih.gov/pubmed/30366834
Retrospective
Reference: Ishiwata T, Abe M, Kasai H, et al. Safety of diagnostic flexible bronchoscopy in patients with echocardiographic evidence of pulmonary hypertension. Respir Investig. 2019;57(1):73-78.
Background: Pulmonary hypertension (PH) and anticoagulation could increase risks of hemodynamic complications and bleeding with bronchoscopic procedures. This study assessed safety of diagnostic bronchoscopy procedures in patients with pulmonary hypertension.
PICO:
Populations:
- Patients with echocardiographic evidence of PH (defined by RVSP >40 mm Hg) undergoing diagnostic flexible bronchoscopy at a single facility in Japan between 2004 and 2016.
Intervention:
- Patients with pulmonary hypertension
Comparison:
- Patients without pulmonary hypertension
Outcome:
- 45 patients in PH group and 90 in control group. Forceps biopsy was performed in 62% of PH patients and 58% of control patients and transbronchial needle aspiration (TBNA) was performed in 13% of PH patients and 13% of control patients.
- Total incidence of bleeding was not significantly different between the two groups. Vital signs at 2 hours post-procedure were not significantly different between the two groups.
Take Home: Diagnostic procedures can be safely performed in patients with echocardiographic evidence of PH, but comorbidities and individual risk factors need to be taken into account during pre-procedural risk stratification.

Flexible Bronchoscopy
https://www.ncbi.nlm.nih.gov/pubmed/29433707
Review
Reference: Miller RJ, Casal RF, Lazarus DR, Ost DE, Eapen GA. Flexible Bronchoscopy. Clin Chest Med. 2018;39(1):1-16.
Summary: Diagnostic techniques include bronchial washings, bronchoalveolar lavage, brushing, TBNA, forceps biopsies, core needle biopsies, and cryobiopsy. Each method of sampling has its own indication, risks, unique instruments, and diagnostic yield and a combination of modalities is recommended to increase diagnostic capabilities. While there are relatively few absolute contraindications to flexible bronchoscopy, a thorough evaluation of the indications, benefits, and risks in context of a patient’s clinical condition and comorbidities is essential prior to performing the procedure.
Sedation in Bronchoscopy: A Review
https://www.ncbi.nlm.nih.gov/pubmed/29433726
Review
Reference: Mccambridge AJ, Boesch RP, Mullon JJ. Sedation in Bronchoscopy: A Review. Clin Chest Med. 2018;39(1):65-77.
Summary: Use of sedation during bronchoscopy has become commonplace and is used in addition to topical anesthesia. A combination of opioids and benzodiazepines is common, although use of other agents such as propofol, ketamine, and other agents are also popular depending on the operator’s experience. There is no standardized sedation practice so choice depends on patient factors, experience of the bronchoscopist, and safety and efficacy profile of the agents used.

https://www.ncbi.nlm.nih.gov/pubmed/32030281
Review
Reference: Morton C, Puchalski J. The utility of bronchoscopy in immunocompromised patients: a review. J Thorac Dis. 2019;11(12):5603-5612.
Summary: Outlines diagnostic rate of transbronchial biopsy in different immunocompromised patient populations including solid organ transplant, hematopoietic stem cell and hematologic malignancies, HIV, medication-induced immunosuppression and chemotherapy, along with primary immunodeficiency disorders. Discusses timing of bronchoscopy, potential complications, non-invasive testing, and future areas of research in the context of the immunosuppressed patient with abnormal chest imaging. Essentially, early bronchoscopy can be helpful, complications generally mirror those of the general population but individualized decisions based on clinical judgement are necessary.
