Prevention of hypoxemia during endobronchial ultrasound-guided transbronchial needle aspiration: Usefulness of high-flow nasal cannula.
Hypoxemia during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is often encountered even in patients without respiratory impairment before the procedure. The aim of this study was to evaluate the efficacy of a high-flow nasal cannula (HFNC) in preventing hypoxemia during EBUS-TBNA. ⋯ HFNC could be an effective and safe device for prevention of hypoxemia during EBUS-TBNA.

Comparative StudyStudy of the usefulness of small-bore aspiration catheters (Aspiration Kit®) for treating pneumothorax.
Small-bore aspiration catheters (Aspiration Kit®) cause less pain than conventional trocar catheters in patients. The objective of this study was to examine the usefulness of these less invasive small-bore aspiration catheters for drainage of pneumothorax. ⋯ The numbers of patients with anticoagulant use (P < 0.0001), ischemic stroke (P = 0.0063), and atrial fibrillation (P = 0.0410) were significantly different between the two groups. No significant intergroup differences were noted with respect to the length of hospitalization, drainage duration, subcutaneous emphysema, and treatment failure. Logistic regression analyses of baseline characteristics showed that the severity of pneumothorax, localization of pneumothorax, and recurrent pneumothorax were significantly associated with drainage treatment failure, but the type of drainage catheter was not significantly associated with treatment failure. [Conclusions] The results suggest that small-bore aspiration catheters, which cause less pain in patients, are potentially useful for pneumothorax drainage.
