It has been demonstrated in the literature that with 20 years of experience, the percutaneous dilational tracheotomy procedure is more affordable, faster to perform, and a generally safe procedure when performed under appropriate conditions. Most case series of percutaneous dilational tracheotomy reveal an equal or lower risk of short-term complications than open tracheotomy. This series demonstrates that tracheal stenosis is a potential long-term complication. Longitudinal follow-up of patients undergoing percutaneous dilational tracheotomy is indicated.
Endotracheal tube cuff deflation/reinflation and pressure adjustment do not reduce the incidence of vocal fold immobility in anterior cervical spine surgery.
To improve the number of qualified high school students entering into engineering disciplines, the University of Arizona (UA) and local businesses have created a program called the Summer Engineering Academy or (SEA). The SEA program has proven to be highly successful during the summers of 1999 and 2000. The idea behind the SEA program is to show students how a concept becomes reality. On this program, student teams designed and rapid prototyped aerodynamic vehicles using SolidWorks™ and Fused Deposition Modeling (FDM) for Computer Aided Design (CAD) and rapid prototyping (RP), respectively. In 1999, two groups of 35 freshmen-sophomores and 47 junior-seniors participated, while in the 2000 program, 52 freshmen-sophomores and 40 junior-seniors attended. Out of the students who attended the program in 1999, 27 students from the senior batch have enrolled in the University of Arizona engineering programs. In both of the programs, 68 female students and 57 students from under-represented groups participated. The students were taught concepts of materials science, aerodynamics, CAD, and rapid prototyping by faculty from UA. The students visualized and modeled to prepare CAD files of the cars. The parts were built using a Fused Deposition Modeler. The vehicles were then tested in a wind tunnel and prizes were awarded for the best aerodynamic design. The students also toured the ACR and Raytheon rapid prototyping facilities during the weeklong program. The design and model competition results were presented to the parents and faculty members of the College of Engineering.
The application of in-line stabilization (ILS) during endotracheal intubation of patients with suspected cervical spine injury makes visualization of the laryngeal inlet difficult1. We tested the hypothesis that the GL2 provides a better view of the larynx and results in a higher rate of successful intubation than the Mac. Materials and Methods Following institutional approval, written informed consent was obtained from ASA I and II patients requiring general endotracheal anesthesia. Exclusion criteria were: history of prior difficult intubation, morbid obesity (body mass index [BMI] > 35 kg/m2), gastroesophageal reflux disease and poor dentition. Patients were randomized into either GL or Mac. After onset of paralysis, ILS was applied. In GL patients, laryngoscopy was first performed with a Mac, then GL. The view obtained with either was scored3. If "good" (I or IIa), intubation was attempted with the GL. Otherwise, external laryngeal manipulation (ELM) was applied and if the view was "good", the larynx was intubated. If not, the attempt was aborted and the intubation was considered "failed". Patients in the Mac group had the same in the reverse order, with intubation attempted at Mac laryngoscopy. Time to intubation was recorded as the interval from when the blade passed the incisors to confirmation of tube placement by capnography. Means were compared using unpaired Student's T-test and proportions, with Chi-test. P < 0.05 was considered significant. Results (See Table 1) Discussion GL provided a good view of the laryngeal inlet in 95% of attempts versus 44% with the Mac. The numbers improved to 100% and 60% with ELM. The success rate of intubation was higher with the GL (100% versus 65% with the Mac), but it took longer. Our preliminary data suggest that in comparison to Mac, GL is a better tool for laryngeal visualization and intubation in patients in whom ILS is applied.
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.
