AN IMPROVED TRACHEOTOMY DILATOR.

The tracheotomy punch for urgent tracheotomy.

Tracheotomy is a commonly performed surgical technique used for long-term mechanical ventilation, upper airway obstruction, need for pulmonary toilet, and as an adjunct to surgery where ventilation is anticipated. Urgent tracheotomy may be performed when difficulty is encountered during an elective tracheotomy, or when cricothyroidotomy is impossible or contraindicated due to distorted anatomy ...

Pediatric tracheotomy.

The procedure of tracheotomy dates back to ancient times. Its use has been adapted in the neonatal and pediatric population over the past half-century. Despite being a life-saving measure, tracheotomy-related mortality rates range from 0.5 to 3.6%, and this procedure is not without significant and sometimes frequent complications. Techniques regarding pediatric tracheotomy vary from surgeon to ...

An Improved WAGNER-WHITIN Algorithm

We present an improved implementation of the Wagner-Whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the Economic- Part-Period concept. The proposed method of this paper reduces the burden of the computations significantly in two different cases. We first assume there is no backlogging and inventory holding and set-up costs are fixed. The second model ...
