Within-subject comparisons of tidal breathing parameters of the two CPAP devices Infant Flow System and Babylog 8000 show: (1) a significant influence of the system used; and (2) that the valveless Infant Flow System increases air flow and tidal volume with less fluctuations in CPAP pressures during the breathing cycle.
In order to minimize the lethal risk of gas embolization, the insufflation system has to be completely filled with CO₂ before connecting to the patient.
Embolisms with the smallest amounts of helium administered via direct venous puncture have an immediate lethal impact. Extended perioperative monitoring and trocar placement under vision should be performed.
A retrospective study was undertaken of 22 carpal scaphoid fracture patients younger than 18 years. Of these, 17 patients received conservative treatment, and 5 received treatment involving screw fixation with or without a bone graft from the iliac crest. Clinical outcomes were evaluated using the Cooney score. Radiographs were analyzed with respect to the site of the fracture, the course of the fracture gap, displacement, and time to union. According to the Cooney score, in 94% of patients, good or excellent results were obtained. A total of 94% of patients considered their result as good or excellent. All fractures healed. Malunion was evident in 1 case.
We report the case of an isolated non-displaced fracture of the capitate in an 11-year-old boy. On the basis of the relevant literature we present a survey of the diagnostic and treatment options. To the best of our knowledge this is the first description of a paediatric capitate fracture in the German-speaking area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
