Cannula

BOSTON — When capturing ROX index in acute hypoxic respiratory failure, time from the start of high-flow nasal cannula therapy impacted the index’s sensitivity and specificity, according to data presented at the CHEST Annual Meeting.

Abbott/Thoratec Corp. announced the recall of its left ventricular assist device implant kit due to complaints of blood leakage or air entering the seal interface between the LVAD inflow cannula and the apical cuff.

Nightly positive airway pressure use has been shown to control obstructive sleep apnea, reduce health care costs and lower the rate of hospitalizations and emergency room visits.

Among pediatric patients hospitalized with bronchiolitis, use of weight-based non-ICU vs. ICU-only high-flow nasal cannula protocols was linked to lower yearly ICU admission rates, according to results published in JAMA Network Open.

Pediatric patients with bronchiolitis who are admitted to hospitals that use more high-flow nasal cannula outside the ICU face longer stays and greater total costs, according to study results published in Hospital Pediatrics.

The addition of high-flow nasal cannula to long-term oxygen therapy may decrease exacerbations among patients with stable hypercapnic COPD, according to a study published in American Journal of Respiratory and Critical Care Medicine.

Medtronic plc announced the U.S. launch of its Kyphon Assist Directional Cannula for use with its balloon kyphoplasty products to treat vertebral compression fractures due to osteoporosis, cancer or benign lesions.

New data published in JAMA indicate that continuous pulse oximetry monitoring is being used often in children hospitalized with bronchiolitis who are not receiving active supplemental oxygen administration — a population in whom this is not indicated.

Eyes with a posterior polar cataract are predisposed to posterior capsule dehiscence during cataract surgery. In such eyes, the recommended surgical strategy is to avoid cortical cleaving hydrodissection. Instead, conventional hydrodelineation is performed. Even with the latter, there remains a possibility of fluid being injected inadvertently in the subcapsular plane, leading to unwarranted hydrodissection.
