急诊护士就当前临床实践中3个问题的非正式讨论

在急诊部使用氯胺酮(ketamine)在过去的几个月里,急诊部的很多人问我如何最有效地指导护士去掌握和使用氯胺酮以及监督病人正确使用这种止痛药。因为有很多人询问我,所以我在ENAListserv上作了一个调查。我收到了很多反馈。在我开始讨论解决方法之前,也许我首先应该概括一下解决此问题面临的困难。虽然无法指出在急诊部正在接受镇静治疗的孩子的确切数字,但是基于我已经得到的反馈信息以及我个人的临床经验,发现不同部门的数字差异甚远。一些同事指出在儿童患者中每年会临床使用中等量的镇静剂一两次。也有一些人指出,在门诊使用中等量的…     

Labial surgery for well women: a review of the literature

This review investigates the quality and content of published reports relating to labial surgery for well women. Electronic databases were searched for relevant articles between 1950 and April 2009. Forty articles were identified, 18 of which included patient data. The specification of the study design was unavailable in 15 of the 18 papers; the remaining three were retrospective reports. No prospective, randomised or controlled studies were found. All reports claimed high levels of patient satisfaction and contained anecdotes pertaining to success. Medically nonessential surgery to the labia minora is being promoted as an effective treatment for women's complaints, but no data on clinical effectiveness exist.     

Effect of alternative photostimulable phosphor plates erasing times on subjective digital image quality

Objective

To evaluate the influence of alternative erasing times of DenOptix® (Dentsply/Gendex, Chicargo, IL) digital plates on subjective image quality and the probability of double exposure image not occurring.

Methods

Human teeth were X-rayed with phosphor plates using ten different erasing times. Two observers evaluated the images for subjective image quality (sharpness, brightness, contrast, enamel definition, dentin definition and dentin-enamel junction definition) and for the presence or absence of double exposure image. Spearman''s correlation analysis and ANOVA was performed to verify the existence of a linear association between the subjective image quality parameters and the alternative erasing times. A contingency table was constructed to evaluate the agreement among the observers, and a binominal logistic regression was performed to verify the correlation between the erasing time and the probability of double exposure image not occurring.

Results

All 6 parameters of image quality were rated high by the examiners for the erasing times between 25 s and 130 s. The same erasing time range, from 25 to 130 s, was considered a safe erasing time interval, with no probability of a double exposure image occurring.

Conclusions

The alternative erasing times from 25 s to 130 s showed high image quality and no probability of double image occurrence. Thus, it is possible to reduce the operating time of the DenOptix® digital system without jeopardizing the diagnostic task.     

Stent luxation: Possible complication of subadventitial stenting in coronary chronic total occlusion revascularization

The entry to the subadventitial space is not a mode of failure, but the road to success in many chronic total occlusion (CTO) percutaneous coronary intervention (PCI) cases. Long‐term clinical outcomes of subadventitial stenting are favorable and similar to intraluminal stenting. However, the subadventitial space histology and physiology remains different to the coronary true intraluminal space. We report a complication specific to stenting of the subadventitial space, where overlapping stents dislocated from one another, which resulted in late non‐occlusive stent thrombosis. We describe, for the first time in the literature, this complication, possible reasons behind, and the ways to avoid this potentially major mischief. © 2016 Wiley Periodicals, Inc.
