AVIATION NURSING IN THE WESTERN AUSTRALIAN KIMBERLEY

ABSTRACT: This article provides a brief overview of the Western Australian (WA) Kimberley Royal Flying Doctor Service and the role of the flight nurse who accompanies patients requiring aerial medical evacuation from rural and remote WA. Two short case histories of head injured patients evacuated from the Kimberley region will be outlined and some of the potential concerns associated with transferring patients at altitude in a confined and altered working environment will be discussed.     

带手套穿刺对留置套管针一次成功率的影响

为探讨戴手套与不戴手套穿刺对留置静脉套管针一次成功率的影响 ,为护理人员的自身防护提供科学依据 ,选取冠状动脉搭桥术病人 12 0例 ,随机分为实验组和对照组 ,实验组采用戴手套穿刺法 ,对照组采用常规洗手后不戴手套穿刺法。结果两组一次穿刺成功率经χ2 检验 ,无统计学意义( χ2 =0 .5 6 3,P >0 .0 5 )。说明戴手套留置套管针并不影响一次穿刺成功率。     

Management of pediatric pontine gliomas

We present 36 consecutive patients with intrinsic glioma of the pons. Tumors with exophytic expansion were excluded. There were 16 females and 20 males, ranging in age from 2 to 13 years, median 6 years. The most common presenting symptoms were cranial nerve dysfunction. unsteadiness of gait, and hemiparesis. Computed tomography (CT) showed a hypodense (17/21) or isodense (4/21) expansion of the pons. Five tumors had areas of contrast enhancement. Following information about prognosis and possible types of management, parents decided for or against radiation therapy: twentyfour children underwent irradiation and 12 did not. Median survival among children receiving a full course of irradiation was 280 days, compared to 140 days in an equivalent group of non-irradiated children. Hemiparesis presenting without cranial nerve symptoms and contrast enhancement on CT scan were poor prognostic factors, whereas sex, age, and duration of symptoms at diagnosis were unrelated to prognosis.     

便携式负压吸引装置的设计及材料学特点

对负压吸引装置便携方式的研究一直是急救医学追求的目标之一，因为它能够极大地促进急救成功率。文章基于这种需要，研制了一套便携式负压吸引装置，并根据实际应用效果，选择优化的制造材料。研制的便携式负压吸引装置主要由特殊设计的储液罐及罐盖、负压产生装置、过渡接头等部分组成，关键部件采用特殊材料制作，体积小，质量轻，操作简单，易于携带，完全能满足临床抢救及治疗的需要。作为一种急救中必不可少的器械，便携式负压吸引装置在急救伤病员运输、转运，家庭急救，及无动力源环境等情况下，对于抢救患者及提高救治效果，具有极大的竞争优势和应用前景。     

FDA’S Perspectives on Cardiovascular Devices

The Food and Drug Administration (FDA) decision process for approving or clearing medical devices is often determined by a review of robust clinical data and extensive preclinical testing of the device. The mission statement for the Center for Devices and Radiological Health (CDRH) is to review the information provided by manufacturers so that it can promote and protect the health of the public by ensuring the safety and effectiveness of medical devices deemed appropriate for human use (Food, Drug & Cosmetic Act, §903(b)(1, 2(C)), December 31, 2004; accessed December 17, 2008 ). For high-risk devices, such as ventricular assist devices (VADs), mechanical heart valves, stents, cardiac resynchronization therapy (CRT) devices, pacemakers, and defibrillators, the determination is based on FDA’s review of extensive preclinical bench and animal testing followed by use of the device in a clinical trial in humans. These clinical trials allow the manufacturer to evaluate a device in the intended use population. FDA reviews the data from the clinical trial to determine if the device performed as predicted and the clinical benefits outweigh the risks. This article reviews the regulatory framework for different marketing applications related to cardiovascular devices and describes the process of obtaining approval to study a cardiovascular device in a U.S. clinical trial.
